It was as impressive as I thought it would be. Fondling my boobs had begun to arouse him, and his prick was already semi-hard, sticking out from his t...rso in a gentle arc, ending in a mushroom-shaped tip that seemed almost too heavy for his shaft. He kicked his boxers over next to my clothes, then returned one hand to my breasts, while slipping the other one between my legs, rubbing it along my now extremely wet pussy lips.I couldn’t take my eyes off his bouncing shaft and his big, swinging nut. If you behave we’ll go swimming today, will you be a good boy?” “yes Mistress” was the only reply I could make, just thinking of fucking or being fucked had my brain aswirl.

Sure enough, there she was splayed out on her towel with her red bag of surprises at her side. The bigger surprise was seeing Tom! He was naked, leaned back against a tree. I wanted her to feel something she feared more than anything, something.Giving her minimal attention throughout the night and teasing her subtlety kept her pining for more. She and I both knew we were going to fuck, but how and why was more valuable to me than just the cock in the pussy. Owning a woman's mind is much more powerful than their pussy alone.

I could feel her hips moving with me, and could sense her orgasm getting closer. Very quickly, and without much warning, her pace became furious and she simply exploded! Her orgasm almost surprised her, and you could tell it was a very welcome experience.I continued to slide inside her, and I could.
