Encounters

What a morning I said to myself as I went out to our sitting room for it was now coming up to lunchtime. I'd fucked Sarah and Carol and had been fucked by Julian and also went down and sucked on Sarah, sucked on Julian and had my own cock sucked by Carol. Yes, a very good morning for me and the afternoon and evening still to come and wondered if I could get to have Grace and for me to tackle the tackle of Sam.

With some sweet talking to Grace during the afternoon, I managed to get Grace into her bedroom and there we fucked and I found that she was as good as Sarah. She'd already been told at how Sarah and I not only fucked in room one but that I had plated her on the floor of the sitting room afterwards and she wanted some of the same. So the prelude was that I went down between her thighs and brought her up to an orgasm and she literally dragged me up her body for me to give her another one with me inside her with my cock instead of my tongue.

She had the same musky taste and smell as that of Sarah and wondered if it was the same with all black women. As to fucking her, there isn't any difference between black and white in that department and knew that this wouldn't be the last fuck we would have together for she said I was the same size as Sam. Now that pleased me and I set about finding this out after dinner. I managed to corner him, if that's the right word, on the settee while the two girls played pool of sorts.

`I know that you've said that you're not bi-sexual like I am, but I can tell you now, that if I sucked on you it won't turn you, I can assure you of that. Sarah has said that you are as big as me and I would just love to see it and taste you at the same time,' I had said.

`Well... I'm flattered Randy, but, well I don't know,' he stammered.

`You'll enjoy it Sam. That I can guarantee. Please? It's been a long time since I last sucked on a man. You've had a woman do it, why not let me show you how good it can be with it being another man doing it.' He thought of this for a minute and I waited, holding my breath.

`Are you sure it won't turn me?' he asked.

`Absolutely,' I lied, for I didn't know if it would or not, but I was not caring about that as all I wanted was to suck on my first black man and hoped, hoped that he would also later agree to having him fuck me.

`Er, well, er, wh....where?' he stuttered.

`Your room,' I said, standing up, my heart thumping away at his now agreeing to it.

`What, what about the girls?' he whispered.

`Fuck the girls,' I replied.

I have,' he smirked. Well one anyway and hope to have the other later.' As I do too, I thought, having the other but not in reference to the girls. He got up and we both went into his room, ignoring the girls as they stopped playing to watch the pair of us go into his room and shut the door behind us.

Sam stood by the bed not knowing quite what to do with himself and so I started the ball rolling by stripping off my T shirt and shorts and stood naked in front of him, my cock sticking out in front of me, throbbing, though I didn't expect him to suck on me but to let him see that I was excited at the prospect of what I was going to do to him.

He was slow, but took his things off and seemed a bit embarrassed at me seeing his cock was as erect as mine and I now knew that we were indeed about the same size in what we had sticking out in front of us.

`Sit on the bed,' I said, which he did and I pushed his legs apart and knelt down in between them, my heart pounding at see that black cock, up and hard in front of me. The flesh inside the foreskin pinky in colour and I licked my lips and lowered my head and took that of his into my mouth.

What bliss to have a throbbing cock once more to suck and nibble as I held him firmly and gently and slowly moved the outer skin up and down the solid muscle beneath it. I used my lips to push the foreskin right down so to be able to tease the G string with my tongue. He gave out a groan as I did and carried on to use my teeth to gently rasp the exposed head as I sucked and worked my hand on him.

I didn't go fast for I loved having this big black cock in my mouth and wanted it to last as long as possible as I sucked and teased him. But nature took over and I felt him start to tremble and he leaned his body backwards, supporting himself with his outstretched arms as his hips started to buck slightly and I held him even firmer as I now pumped his cock and had the first taste of a black man's sperm come into my mouth.

It was slightly spicy but most enjoyable as he added more and yet more to make it feel like I had a bucket full of his semen there which I moved round in my mouth before swallowing. It was lovely having it slide down my throat and I crowed in my mind at having this first black man come in my mouth.

His cock was still throbbing away when I lifted my head up off of him so that I could see the glistening head, still with some semen coating it that I then licked off, cleaning him up with my tongue before finally and with some reluctance, let go of him and stood up before sitting down on the bed next to him.

With me letting go of him, he flopped his body back on the bed with a big smile on his face at the pleasure I had just given him. Well I had got pleasure too in the sucking of his erection and smiled back at him when he opened his eyes to look up at me.

That was great man,' he said, his eyes alight. I didn't know that a man could do that better than a woman.'

Well a man knows from having been sucked just how to do it properly,' I said as I lay down next to him. Now I don't expect you to suck on me, but, well, would you jerk me off instead?' I asked, hoping that he would at least do this for me. He looked down to see that my erection was now lying up on my stomach and seemed to think about this for a moment before propping himself up on his elbow and have his other hand come over and lift my cock upright.

It's hard and I can feel it throbbing, just like a pulse,' he said, looking down at it before he slowly, with a firm hand, began to move the flesh up and down. The skin is soft too.' I gave out a low moan and closed my eyes as I had his hand now slowly jerking me off and as I was so much aroused, it wasn't long before I knew that I was going to come.

Harder, harder,' I said. I'm nearly there.'

`If I do, it's going to shoot out all over your stomach,' he said, almost slowing down.

I can wash it off afterwards,' I said between gritted teeth. Now harder and faster.' This he did and groaned again as the first emission shot out of the eye, splashing up on my stomach to be followed by the rest until I was empty.

I felt it coming up,' he said in awe, and some of it on my hand now,' he said as he let go of me for it to flop back on my stomach. I lifted myself up and took the hand that had been round my cock and licked off the sperm that had landed on it.

I didn't know I tasted that good,' I said with a smile as I licked my lips. Thanks Sam, I needed that release. If you were like me I would now kiss you for doing that,' I said as I lay back on the bed.

`I...I, if I was like you, I think I would have kissed you too. I would have if you were a woman,' he stammered.

`Being bi-sexual is that I play the part of a woman as well as that of a man, so I wouldn't mind if you kissed me,' I said softly, my heart thumping away again as I looked up at the indecision in his eyes. He must have enjoyed what I had done for him for he wavered and slowly leaned over me and gave me one of the softest of kisses I had yet received from either sex.

He gave a little laugh after he had kissed me. `Don't think that because I've just given you a kiss that I'm going to suck on you for I'm not. I didn't mind jerking you off but that's as far as I will go.'

A pity,' I said smiling back up at him. With you having such a lovely cock, I would very much like you later to fuck me with it. That's another experience you would enjoy too, it being that much tighter than the fucking of a woman.'

`I don't know about that, putting myself, er, where the sun don't shine,' he said.

`That's no problem when you're wearing a condom,' I said.

`I don't know,' he replied, and I left it at that for the time being, for now having let me suck on him, he might come round to agreeing to putting his cock up in my backside and fucking me with that lovely black tool. With a sigh at what he was missing, I got up and put my T shirt and shorts back on, him doing the same before we returned to the sitting room. I saw the looks on the faces of the two girls and the question that was in them.

Don't ask,' I said. It was man to man talk.'

`About us?' asked Sarah.

`No.'

Oh,' and paused before going on. Do you think she will want another sample tomorrow?' she asked with a smile, giving her lips a lick with her tongue.

I doubt it,' I said, guessing as to what sample she was referring to, for she only took a couple of samples the first time I was here, though they will probably want another blood sample. That was a daily thing.'

`Pity,' said Grace, looking pointedly at my groin and giving me a grin when she noticed that I had seen where she looked in asking the question.

Well I'm for bed,' I said. Goodnight all,' and went off into my room to sleep on my own but it was the only night that I did, for the girls finished up swapping places every other night thereafter.

Grace was the first one to come into my room after the lights had gone out and with the door being opened, I turned on the bedside light and saw her there in her dressing gown. I knew why she was there and gave her a smile and opened up the bed cover in invitation. She gave me a smile back and came over to the bed and took off the dressing gown for me to see her naked body. And lovely it looked. Black all over with two big tits that looked firm and had a small bush of hair between her thighs.

I've been looking forward to this after hearing what Sarah said about you,' she said as she got in beside me, her hand going straight down under the cover to find that just the sight of her naked body that would be mine for the night had roused me up to a full erection. Wow. It feels as big as Sam's,' and pushed the covers off to have a look. Definitely! Sara said you went down on her,' she said, cuddling up to me, her body feeling quite hot against mine. Would you do the same for me?'

`Of course,' I said, pushing her onto her back so that I could half lay on one tit at least as I kissed her. Her lips were big and soft and her mouth opened so that our tongues could touch and play with each other. I then rolled fully on top of her and began to kiss my way down her body, pushing the cover down as I moved until I was between her open legs and began to use my tongue and teeth to excite her clit and vagina.

She had the same musky smell as Sarah and gave out a groan and a squirm as my tongue rasped over the clit for the first time. I managed to get my shoulders between her thighs as I began to really plate her, switching from clit to vagina feeling her give little starts at my technique in cunnilingus. It didn't take long before her thighs gripped the sides of my head as she began her orgasm, having her trying to mash her body down onto my mouth as she shuddered with a small scream as she came. She was much like Sarah in the fact that her juices had a slight spicy taste which wasn't bad to take in, also like Sam though he had more to give me than what the girls produced.

Now Randy, now!' she cried out. Put it inside and fuck me!' Pulling at my ears and didn't need that really and quickly moved up her body and let my cock slide up the wet slippery slope and entered her to a big sigh as I filled her. My cock now really throbbing at being in the heat of her insides and feeling her using her muscles to squeeze me. It was lovely as the others at being where it was though not as tight as a man's backside, but what the fuck. I was there now and so I fucked her.

Yes, yes, yes,' she cried to my thrusting. She was right! It feels much bigger than it looks and it is the same as Sam's,' she finished with a gasp, her face smiling up at me as I moved inside her. It was only my grunts and her gasps that could be heard for the next couple of minutes as I ploughed her field.

`I'm nearly there,' she panted as her fingers now began to really dig themselves into my shoulders as her thighs tightened themselves round my waist, her legs moving up higher as she began to buck beneath me. As she began to shudder, her body all tense, I let go and started to come inside her and she gave out a loud cry as she had her orgasm at feeling my sperm hit her insides.

Her back had been arched as she came and when finished, she went rather limp and flopped back under the weight of my body on top of her. Her breasts were as sweaty as my chest as they were flattened, both our chests heaving as we took in deep breaths. Her eyes were sparkling and had a big smile as I leaned in closer for us to kiss.

That was just great man!' she said, flexing her muscles round my still hard cock inside her. Let me suck on you now,' and gave out a little cry as I lifted myself up, my cock sliding out of her at the same time. I rolled over onto my back, my wet cock slapping itself on my stomach as she moved down the bed on her side and quickly took hold of me and took me into her mouth.

She was as hot there as her fanny had been and she made little noises as she sucked away, getting a taste of her own fluids as she pulled out what I still had left inside my cock before licking all over the bare fleshy head. It was a wet kiss I then got after she'd come back up the bed and into my arms.

`I can't wait to have that again Randy,' she sighed and then for the next hour, she played with my dick and balls, nibbling and sucking away, being able to take the whole of my flaccid piece it to work her magic in rousing me up again. Which happened and got to fuck her for the second time before we finally dropped off to sleep.

The following night it was Sarah in my bed and we went through the same process of having each other as with Grace and then it was turn and turn about between the two of them. Them switching between me and Sam, him getting as much as me.

So every morning sometime after breakfast, I would go into room one to lay on the couch with Carol, fucking her and giving over my sperm sample at the same time. Then during the afternoon, I would go into Sam's room and suck on his rampant black cock, loving the feel and taste of him in my mouth and it took over a week before I finally got him to agree to using his cock up my backside. What a thrill that was to once again have the hardness of a man fill me in our fashion as he fucked me. This then took over on my sucking of him though I still did after pulling off the used condom to pull out any remaining seed inside that wonderful cock of his.

I even got to fuck Julian a couple of times over those three weeks, letting him fuck me too but the highlight was when I got Sam to see to me. We had gone into his room for a sucking session, that being me sucking on him, but not getting him to suck on me. We'd both stripped off and had sat down on the bed, both of us with an erection sticking up though, as he wouldn't suck on me, I would usually jerk myself off as I sucked on him and had my release when he came in my mouth, my seed being shot out onto the carpet beneath the bed. But on this day, I took hold of his erection and gave it a few rubs before speaking. Sam. Will you please fuck me with this wonderful tool you've got? I've had it in my mouth and would like very much for you to fuck me with it.' He started to speak but I stopped him. I know that you don't want to suck on me and definitely will not let me fuck you, but please fuck me. It won't turn you into a bi-sexual, believe me, but you will enjoy the difference between having me and having one of the girls.'

He started giving reasons why he shouldn't which I shot down every time and finally got him to agree to at least fuck me once and that if he liked it, would do so more often. Well it was enough for me and quickly got a condom out of the drawer and went onto my knees between his legs and took the head of his now really throbbing cock and gave him a few sucks before rolling the condom down on him.

I got up onto the bed on my knees and had him get there behind me.

`I don't know if it will fit,' he said as he saw where he was going to shove his cock.

It will,' I said getting a bit frustrated with him dithering. Just put it at the entrance and push forward. I promise you that you'll enjoy the tightness,' and bent myself really forward to get as much of him inside as possible and began to drool as I felt the head of his cock nuzzle the entrance to my backside, and lo and behold, he began to push himself into me.

I gritted my teeth, trying to force myself to relax and really felt some pain as he stretched me as the head widened me far more than Julian's cock head did and he suddenly was inside and I had the whole length of his cock slide in until I had his thighs up tight to the cheeks of my bum.

Wow!' he gasped. You weren't joking at it being a tight fit,' and I began to flex my muscle around the shaft, feeling him throb inside me. His hands were firm on my hips as he held me and didn't need my telling him what to do for he began to move himself in and out giving me that lovely thrill of having a new strange cock giving me that internal massage.

I could see in my mind's eye the picture we made on the bed. Me on my knees with him between my legs, his hands on my hips as his own hips moved in the action of moving his cock in and out of my backside. I loved it! He was finally fucking and giving me the pleasurable sensations that his cock generated inside me and I knew damn well that he was enjoying this fucking of me in this fashion.

It was only a minute or two of having him enter me before he held me tighter as he began to ram himself tight up to me and then felt that extra expansion of his cock as it began to give out that extra throb as he started coming in the condom buried inside me.

He came to a stop, leaning against my rear end, panted heavily as though he'd just run a mile in record time.

Wow!' he gasped again, his cock still twitching and throbbing inside me as I kept up the flexing of my inside muscle. I had no idea it would be as good as this.' This made me glow inside and knew that he wouldn't say no to fucking me again and I had loved it too. So much so, that as he had come inside me, I, without touching my own erection, came myself as it bounced beneath me as he had been thrusting himself inside me, shooting my load out onto the bed covering and still had it dribbling out when he came to a stop.

I gave out that usual little cry at losing what had just given me a thrill and quickly turned round to pull the condom off him as he sat back on his heels with a bemused smile on his face. I threw it to one side as I lay down and took the head of that still hard cock into my mouth and sucked out what was left of his seed to swallow before licking the whole head clean.

I felt just like the cat that had got the cream as I pulled him down and kissed him, telling just how happy he had made me with what he had just done. He must have still been in that bemused state for he didn't object to my kissing him but didn't do it long in case it upset him which I didn't want to do for I wanted him to fuck me again another day.

So when he wasn't giving up his sperm to the lab boys and in his fucking of the girls, he was using the rest inside me, and I loved it. It had been my first time in having had a black man fuck me and lived up to the theory that all men of his colour were well endowed.

Those three weeks were a glorious fuck fest for me in having all three females to fuck and have the two males fuck me. I was in heaven again and was really sorry when it came to the end of this guinea pig stage that the clinic wanted.

Breakfast was over and the two girls and I kissed as we said our goodbyes and I think they had guessed that Sam had been fucking with me for they didn't show any signs of surprise when Sam and I kissed. It was a peck on the cheek to Carol as they said their goodbyes to her as she thanked them for being at the clinic as she handed each of them an envelope which held their stipend for being guinea pigs.
