. I just didn't want it to end yet," I stammered. They looked at me, surprise showing clearly on their identical faces."You don't really, really think...we'll be done tonight if you lose it now, do you?" Katie asked incredulously."Dude," Becky added as they both giggled at me again. They knew how much I hated that expression. I had to admit, they did a great Valley Girl imitation. Identical twin Valley Girls — I didn't think I had ever seen that before."We can't stop yet; you still have some. I didn’t want to spoil him all at once. Swaying to the music, my red panties felt tight. I could feel my engorged clit pushing against the fabric and was sure that someone would notice the wet stain between my legs. Standing, I spread my legs wide, and, in a sudden motion, dropped my pelvis to the floor. I was doing the splits, much to the delight of the crowd. Who knew yoga could be so useful I chuckled to myself. I pulsed there for a while, my pussy bouncing off the floor, then leaned back. "Oh God, yes, yessss, fuck, fuuck, fuuuuuuck!" she groaned as her muscles clamped my fingers and her thighs began to shake. Suddenly, a massive orgasm swept over her as her whole body went into spasm. Her body arched and she let out a long high pitched scream.Slowly she came back down and laid flat on her back, panting heavily. "Oh fuck, that was good" she moaned. "I never thought it would be that good"."Has no-one ever gone down on you before?" I asked.She rolled slowly around so that she was. Gently he rubbed along my pants and I felt very aroused and moist. His bulge was even bigger now and I reached down to feel his hardness. We both rubbed and felt over our clothes; Sam got even harder and I got wetter.We were not speaking — our hands were doing all the talking — and I wanted to fuck him but it would not be on this settee. My bed I was in the adjoining room and, with the sexual heat at fever pitch, I whispered, ”Hey, Sam, why don't you come to mummy's bedroom and we’ll see what.
