We were playing a little game where she was telling me a story, I honestly can't remember what it was now. Everything up until then got washed away by...what is about to come next. I was hard and getting closer to cumming."I don't want you to cum yet" she said"When do you want me to cum" I asked.She paused, thinking something over, probably wondering if she should continue. "I want you to cum when i'm slapping you. Can you do that? Do you want to do that?"Either my head or the room started. I was kissing her neck about to enter her when I spotted a middle aged guy, he watching through the car windscreen.

He moved closer and instead of entering her I pushed my cock back and forth over her entrance as I whispered in her ear “ we’re being watched .“ Her eyes were closed and She obviously didn’t believe me. I slipped her bra cups up over her large breasts and. He suffers from erectile dysfunction, so she's had a very long dry spell. Which is a pity given that she is a very attractive petite blonde."Ohhhhh ... ahhhhhh ... so good" she moans as I continue to slide my cock in and out, with my balls slapping against her ass on each inwards lunge.She is very wet. I was surprised how wet she was when I first entered her about five minutes ago. I think I'm helping her release ten years of pent up needs. I don't know how she has gone that long without being. Although Trip was still as emotional as ever, he had learned to hide his emotions for longer periods and let them out with nobody around, preferably in their meditative white space. T'Pol had made a point of engaging him in long talks about his sister Lizzy and their baby Elizabeth, to stir emotions in him and took pride in the fact that it took sometimes more than an hour for him to succumb to tears. At times he even managed to return to calm without the need of her cradling him. She did.
