I noticed my friend James' gorgeous sixteen-year-old sister Laura the first time I visited his house. James and I were both in the same class at Birmingham University, but since his family was in Dudley, he didn't need to move out. Once we had discovered that we were both bisexual and attracted to one another, these visits became very frequent, as my room in the house I rented with other students was too tiny to spend much time in,

On each visit, it took all my will power not to stare lustily at Laura's petite body whenever she entered the room. She had the same beautiful dark skin of her brother, huge brown eyes, the cutest face framed by straight, black hair coming to just above her shoulders, and the way she swung her hips whenever she moved was mesmerising. However, while she was friendly towards me, I didn't think she was interested in me in the same way, and anyway, I was having too much fun with James to think about making a move.

Then one night, James and I were in his room. He was sucking my cock while I sat on the bed, when I noticed that the door had been left ajar. I was about to tell James to close it, but then I noticed it open a bit wider to reveal Laura, stark naked, crouched with her legs spread wide open, watching us while she fingered herself. This knowledge of being watched turned me on even more, and I soon came hard in James' mouth. Through my half-closed eyes, I saw her quietly close the door.

A month later, when I was staying with James for a week during the mid-semester break, he caught a nasty cold and went to bed early on the Friday afternoon. His parents had tickets for a concert in Birmingham, leaving Laura and I alone to entertain ourselves for the evening.

It began innocently enough, with pizza in the lounge while watching TV with the curtains drawn. She looked very sexy, still in her school uniform since she had already had her half-term break. It consisted of a white shirt, through which I could clearly see her bra over her dark brown skin; a short, green, pleated skirt to match the tie that she has discarded on coming home; and white socks coming up to just below her knees. After a couple of minutes, she moved closer to me on the sofa and cuddled up to me. I put my arms around her and looked into her eyes.

"You're so beautiful Laura," I told her, lowering my forehead so it touched hers.

"Thank you," she replied, pressing herself harder against me.

"I saw you watching me and James the other week," I said. "Did you enjoy it?"

"Yes," she replied hesitantly, looking away bashfully. "You didn't mind, did you?"

"No, it was great, I loved the feeling of being watched. Did you tell James?"

"No," she replied, "I didn't want him to know I was jealous. I thought maybe you just liked boys, but..." She completed her sentence by kissing me gently on the lips. I kissed back, slipping my tongue into her mouth and meeting hers. "Will he be angry with me for this?"

"I don't think so," I replied, my erection beginning to rise, "it was just a kiss, wasn't it?"

For an answer, she unbuttoned her shirt and pulled off her socks. I unbuttoned my shirt and removed it while she took hers off and removed her skirt so that she stood on the carpet in her white knickers and bra. As I pulled down my trousers and took off my socks I noticed that part of her knickers were soaked. I stood up to face her, and as I did so the tip of my cock popped out at the top of my briefs.

We kissed again, our hands running over each other's backs, my hands finding the clasp of her bra. We stepped apart allowing her bra to fall to the floor, freeing her beautiful, pert, brown breasts, the nipples hard and prominent. She reached out, pulled down my pants and began massaging my cock in an exploratory way, while I removed her knickers and threw them in a corner.

I tentatively traced the moist lips of her vagina, watching her delicate brown hands pull my pale foreskin backward and forwards over the head of my penis. I leaned down and begin licking her nipples, then reached around and, clasping her buttocks, lifted her up and sat down on the sofa with her on my lap, her damp thighs on either side of my legs.

"Are you ready?" I asked her.

"I'm ready," she replied, lifting her knees up on to the sofa. With my hands holding her waist, she raised herself up and forwards so her dripping pussy was directly above my hard cock. She put one hand on my shoulder to steady herself and held my dick in position with the other, then tilted her face down to kiss me lightly on the lips. Our lips parted and she lowered herself slowly, her tight pussy squeezing my penis firmly as it slid wetly around it.

Laura closed her eyes and sighed with pleasure through her parted lips, and then I felt a slight resistance at the tip of my dick. She winced slightly and her eyes watered, but then she continued sinking down, her vagina swallowing my cock. Finally, she reached the base of my cock, and moved her arm round to my back, pressing her breasts against my chest. Now her lips were level with mine, so we kissed long and hard.

Once Laura had recovered from the initial pain, she lifted herself up again until my cock popped out. I was so hard that she didn't need to hold it in position as she lowered herself down, the entrance slightly easier this time, but still a very tight squeeze. She moved down a little quicker and went straight up again after she reached the bottom, keeping the tip of my dick inside her.

I slid my hands up from her waist, over her back to her shoulder blades, and then leaned forwards to bury my face in those irresistible tits, bouncing as she moved up and down. The inside of her slippery pussy around my cock sent a wave of warmth through my groin. Laura began to move faster, moaning softly with pleasure and clutching at my back. Those moans grew louder when I nibbled and sucked on her nipples.

She began rotating her hips, grinding our short and curly hairs together. I licked her neck and chin before slipping my tongue into her mouth. On the verge of ejaculating, I quickly moved my hands down to her buttocks, lifted her up and moved her back so my cock stood up through her black bush, its throbbing head lightly touching her stomach.

We rested for a minute, snogging passionately. Then, after we'd recovered and my dick had softened a little, I got her to lean back and to the side so that she lay on the sofa. I held myself above her while she wrapped her legs around my back. Gradually, I lowered myself on to her, but keeping most of my weight on my arms so that our stomachs touched and her breasts pressed against my chest. I held my cock so that the tip touched her opening for a while, then as I kissed her and manoeuvred my tongue around in her mouth, I slowly entered.

The tight wet membrane of her cunt caressed my penis as I pushed it in, until it would go no further. Then I began a slow, rhythmic withdrawal and re-entry, whilst exploring her tongue with mine and moving my hands down to knead her buttocks. After a minute we both began breathing heavily and moaning from the pleasurable sensations shooting through our bodies, and I began going faster. Laura broke away from the kiss, arching her back, letting out louder and louder cries of pleasure.

We began to near orgasm, so I slowed my pace, increasing our anticipation until it was unbearable. I withdrew and penetrated her one last time before she let out one long, loud moan, her whole body tensing at once with her orgasm. My own climax brought a groan to my lips, and I came powerfully inside her, before collapsing, my face in her breasts.

We lay like this, smelling each other and feeling our sweat on our skin, for several minutes, before I withdrew from her. As my semi-erect cock came out of her pussy it was accompanied by a large amount of cum, its pale-white colour contrasting beautifully with her black hair and brown skin.

I scooped her up in my arms and carried her upstairs, as quietly as possible since we didn't want to wake James. I took her into the bathroom and locked the door while she sat on the side of the bath and got the shower ready.

As she sat there, she spread her legs and began touching her clitoris. I knelt down at her feet and began to lick her pussy, still glistening with semen and pussy juice. I lapped at the lips to clean them, thrusting my tongue deep inside her, then returning to her clit. I slowly slipped two fingers inside, feeling for the slight lump I'd read about, then began rhythmically circling and massaging it.

At this, Laura began quietly moaning again, and put her hands around my head, pushing my face into her pussy. I sucked and licked at her clit and labia, and thrust my fingers faster as her moans got louder. Her g-spot swelled between my fingers, and she began thrusting forwards with her hips, humping my face as I licked harder. Then she let out one final cry and contracted around my fingers, her grip on my head pulling painfully at my hair.

She pushed me gently away, and I removed my finger, producing a delightful slurping sound. Giving her vagina a final lick, I stood up, admiring her firm, dark brown body.

"Shall we shower then?" I asked her.

"You don’t want me to return the favour first?" she replied, tilting her head to the side and fluttering her eyelashes in and impossibly cute gesture.

"Oh, if you like," I replied, "I didn’t want to presume…"

“I would like to,” she replied. “I was so jealous of James that night.”

My cock had already started to become erect again from licking her. I sat down in her place on the side of the bath where she had and she got down on her knees, her big brown eyes looking up into mine as she took my cock in her mouth. First, she just licked at the head with little exploratory tongue movements, but then grew more confident and licked strong and firm, bringing it up to a hard erection.

Then she started sucking, moving her mouth back so it almost slipped out and then pushing forwards again so her wet lips stroked it. She wrapped one hand around the shaft and massaged it with a firm grip, and sucked harder and faster. At first, I thought I wasn't going to cum due to having ejaculated so recently, but gradually I felt the pressure building up in the base of my dick. I put my hands around her head stroking her hair, feeling her head thrust back and forth, her mouth causing divine sensations in my cock.

One long, strong suck licking the head with her tongue at the same time and massaging my shaft hard, and I came. She swallowed the first two squirts, but she had to have a breather for the third, so it hit her next to the nose and dribbled down, the whiteness showing up against her dark skin. Only some of the fourth landed in her mouth, the rest running down her chin, but she took my cock back in her mouth for the rest, then licked and sucked up the remaining semen that dribbled out.

I helped her into the shower, and we washed each other, too drained to do anything else. Once we'd dried, we went into her room where we fell asleep in her bed, her head and breasts resting on my chest.

We were woken by the sound of her parents putting their key in the lock downstairs, so I kissed her cheek and ran silently from her room to James' and got into my sleeping bag on the floor. Breakfast was going to be interesting, was my final thought as I closed my eyes.
