“Uh, huh,” she half screamed. I spanked her ass again and shouted, “Now!” I could see her push back and feel her tummy tense as she pushed her... water out. “Hhhuuuuggghhh,” she groaned out as her water jetted to the other end of the tub and splashed against the wall. I kept rubbing her pussy furiously and shouted, ”Cum, now!” She pushed out more water and then began to tremble and scream with a ripping orgasm. Streams of water were still flying out of her ass, water was dribbling down her pussy. Then they walked back out and into their living room. I closed the curtain and lay in bed, as the sounds slowly filtered out, they were fucking, and they both drove me crazy, lying there naked, eyes closed, and visualising their bodies enmeshed in copulation.My alarm went off at six and the first thing I did was peek through my curtains to catch a look at him, but everything was dark.After work I sat and ate a microwave meal, and was almost finished, when I heard them again and my heart. It felt so good, I knew I wouldn’t last much longer. She must have known, because as she pulled me out of her mouth she cupped my balls in one hand, looked up at me and said, “I want to taste your cum.”I felt my balls begin to tingle immediately at the thought of cumming in her mouth, and I reached forward with both hands, gently holding the side of her head to keep it in place as I pushed my cock back towards her open mouth. This time, as she took my length in her throat, I clamped my hands. Jon and I shook hands before Mandy and I kissed and hugged our ‘hello’s’. Even just the sight of Marie embracing Jon and kissing him lightly made my cock jump and if I had any doubts about going through with this, they were already totally dispelled. We were clearly all nervous but the wine soon loosened everyone up.Marie and I looked across the table at Jon and Mandy and I suggested that Jon and I should swap places to mix up the group a bit. Nobody objected and I slipped my arm around Mandy’s.
