As we walk over I ask if she needs someone to wash her back for her...and she turns around with a big smile. "Only if I get to return the favour - but we will need to be quick" she says in eager anticipation. I tried to contain my excitement as we walked by the university crowd outside the showers. As we entered the shower stall together we got the "we know what you are up to" look from a few of them. We quickly stripped down and admired each other's nakedness. Her tits were small but firm with beautiful nipples that were full of excitement. The rest of her body was nicely firmed and rounded with all the hiking. I was nearly fully aroused as she stepped into the stream of water. My hands explored her soft skin and deepest parts as I lathered her with soap. She took the soap from me and washed my backside first. "Oh Pat, I love that ass of yours". As her hands worked my butt cheeks, a finger slipped up and slightly penetrated me. She turned me around, now completely aroused and took the soap to my cock and shaved balls. She turned back around, bent over and said "take me from behind, but be quick because I'm ready to come". Well so was I and it did not take us long. I had my hands on her hips, penetrating her slowly at first then thrusting my cock into her hot pussy. My hands reached further forward to massage her breasts. Her hand had reached up between us caressing my balls between strokes. "J, I can't hold back, I'm coming, I'm coming" I said hoarsely. "Yes baby come in me, give me all your cum" as we began to shake. "Oh God, I'm coming too, don't stop. Yes, yeess, yeesss, oh God yes. Fuck me hard baby." My cock finally slipped out of her after the convulsions stopped and she turned and pressed her body against mine. The water continued to pour down, then stopped as the 5 minute meter expired. Our lips met, tongues exploring each other mouths and we held onto each other not wanting it to end, but knowing we had to return to the campsite. She shared her towel and I quickly dried myself off, and hurried back to the campsite. J lingered in the shower, showing up a few minutes later. "Nothing better than a long shower at the end of a hike" J said smiling at the three of us. I could not have agreed more. I grabbed m towel and headed back for my second shower.
I can't wait for our next adventure with them. Finding ways to sneak away and do some real exploring with J. And just maybe this time we will all be naked for the next time we jump in the lake...and all that that will bring.
