"Not that you didn't last week, but..." Now if I could just shed those last four pounds, I'd be well away." She replied, after a pause."You're the sam... size as you were last year, now. You don't need to lose any more." Down below I'm back. I'm still uncomfortable in all my bras — I think I've gone up a cup-size." I still don't think you need to lose any more." Because I went up a cup-size?" she smiled, gently."You know that's not that important to me." You didn't show that last night.". As we calmed down Janis turned in my arms and kissed me."Thanks!" she said picking up her robe and sliding it over her back. She let it hang open loosely and winked at me as she left.I stood naked with my limp cock dripping it's last cum drops onto the floor thinking about what had just happened. I had never been unfaithful to Lynn before and I didn't want to lose her but I desperately needed to have Janis also. As I thought about how I was going to keep both I dried myself off and got. As the ship explained to me, the fusion power plant in the rear could generate a small black hole about two meters in front of the craft, thus 'pulling' us forward at an amazing rate of speed. To turn and go in the opposite direction, the craft would turn off the black hole, flip on its axis and generate a new black hole in what was the rear (but now was the new 'front') and we would slow, stop and quickly accelerate in the opposite direction. That wasn't exactly clear to me, but became clear. The room echoed with squeals, moans and groans as the threesome pleasured each other. Suddenly Chuck groaned and climaxed. His head was spinning as he filled Dora with his cum. Buy still Karl was thrusting furiously. It was another couple of minutes before he exploded deep in Chuck’s arse.The three of them separated and lay on the bed puffing. No-one spoke for maybe two minutes. Then Dora looked at her husband “my God” she said staring at him “you actually enjoyed all that didn’t you”. Chuck.
