Then it happened. We had been hiking that day and everyone was tired. I heard Judy tell Bill she was going to walk over and take a shower before bed. ...As she went to her tent to get her stuff, I also told Sarah that I was going to shower quickly and would be back in a little while. I got to the shower first. I had only intended to masturbate in the shower knowing that Judy would be showering herself so close, savoring the thought of the water running over her 5'2" 115 lb. body. Her brown hair. " Shelly pleaded. Now as a guy, when a pretty woman begs me to stick my cock inside her cunt, who am I to say no? Plus, how can I say no. I had Shelly lean against the table and spread her legs. I got between them and placed my cock at her entrance. She was dripping wet. "See, there is no way that is going to fit!" Shelly said. "Hold your lips apart and watch this." I asked. Shelly pulled her lips apart and I pushed my cock into her fine cunt. But I did not stop at half way, I pulled back and. Then without warning my cock let out a huge stream of cum into her mouth. She didn't expect it either and gagged alittle forcing her to swallow. My body went limp and I couldn't believe that something like a finger in my ass made me cum so much more than normal. "I told you, you'd like that" she said while giggling. It took awhile for my body to recover when she said "Now it's my turn, hun!" She went to the bathroom for alittle while and to my suprise came out totally naked. "I want you to. .. ohhhhhhh!" Jan indeed got quite vocal, but by that time no longer cared as I moved smoothly in and out of her whilst gently caressing her clit, until her cries ended abruptly in a loud squeal as she orgasmed on my pistoning cock just as I'd timed my own climax to perfection."You naughty man, after all my good intentions," giggled a blushing Jan."Hey, you grabbed me remember?" I chuckled as Jan got out of the bed to throw a robe on and head for the bathroom.Throwing on a robe myself, I padded.
