"Please Bec, push down on me." and with that I felt the first touch of her hot wet cunt envelope the head of my penis. The feeling was indescribable and every nerve was tingling with anticipation. Slowly, ever so slowly she lowered herself onto my rod. The heat, the wetness, the passion... Finally she had lowered herself all the way achieving maximum penetration. As she settled all her weight onto me I thought I was going to cum.
"Stay still for a minute please Bec, I'm really close."
I looked back at Bec and noticed she'd arched her back and thrown her head back. As she began to squirm on my cock she started breathing quite rapidly and let out a slight moan of pleasure. She looked down at me and said "Oh God Tony, that feels so good."
"Look Bec, I might not last very long this morning, I'm really worked up."
"That's OK I understand, but I really want to ride you and feel you inside me, I want to go for it."
"Just do it, as long as you understand..."
With that, Bec, her eyes closed tightly, began lifting and lowering herself on my shaft. Slowly at first but as her breathing began to quicken she increased the tempo. I reached up and cupped her breasts as they jiggled up and down with her momentum. As I felt the first sensations of orgasm spread through my groin I pinched her nipples quite hard which evoked a guttural groan from deep inside her throat. Watching her and the look of pure ecstasy on her face was too much for me and I began thrusting to meet her rhythmic movements. I was well down the path towards orgasm now and so I said "Is it OK for me to cum?"
Bec hissed "Fill me with your cum Tony, just fill me with it."
"Ohhhh fuuuck, here it is" and with that I thrust deeply into her beautiful hole and began erupting my semen deep inside her. Bec moaned and said "I can feel you cumming" as contraction after contraction pumped more lava into her. My orgasm seemed to go on for minutes and at one stage the intensity was so great I thought I might lose consciousness. Bec kept riding me until well after I'd spent my load but she seemed to fall short of orgasm. She slowed her rhythm until she sat still on top of me; as she lifted herself off my slowly softening cock a cocktail of semen and vaginal juices dripped from her hole splattering onto my cock and balls. Bec rolled off and lay on her back beside me on the bed. After a moment she said "Do you mind if I keep going I didn't quite manage to orgasm?"
"Please do Bec, can I help?"
Bec nodded and put her hand between her legs and began masturbating. It was awesome to watch my beautiful twin sister lying beside me stimulating her clitoris. She was using her middle and index fingers in a circular motion to get herself off so I rolled onto my side and placed my hand between her legs feeling for her vagina. As I slipped two fingers inside she moaned softly and began rubbing more rapidly at her mound. I was astonished at how wonderful her cunt felt full of our juices. So hot and swollen and oh so slippery; I was amazed how the mixture of our juices could create so much viscous and silky body fluid. I could feel it running freely from her vagina and down over her anus. I probed her tight anus with my middle finger pressing against the muscles until it slipped in to the first joint Bec moaned and pressed against me and I remember thinking that if my cock was still hard, and Bec was willing, she was lubricated well enough for me to penetrate her anally. I'd never done that before but somehow it seemed perfectly natural at this time.
I sensed Bec was getting close to orgasm because she'd clenched her teeth and had a look on her face that could easily have been mistaken for pain. I plunged my fingers in and out of her hole as she attacked her mound and clit with gusto. Bec began to arch her back and turned her head away moaning "Yes... yes... yes..." as her orgasm neared. Then with a cry of "Oh God YESSSS!" she went into an uncontrollable spasm of contractions and closed her legs tight together on my hand as if to stop further movement. I could feel her cunt and anus contracting with each orgasmic spasm and after maybe a dozen or so she slowly relaxed and settled back onto the bed. Bec must have felt quite self conscious because she looked at me sheepishly and gave a nervous giggle.
