Emma and Kate didn't want anything to eat. They drank some water and said, "How about skinny dipping. That water looks too good to miss out on."Dan an...d Lana looked embarrassed. Lana replied, "You guys go. We'll wait here for you."Emma and Kate both stood up and without waiting started to undress. Neither girl showed any sign of embarrassment as they pulled their tops over their heads, undid their bras and slid the straps down their arms placing both items of clothing on the blanket they had. A small dollop of precum emerged as I tickled his sensitive spot. "Mmm, look at that. I'm making you dribble. You like this don't you?" A grunt sounded as the veins popped out of his neck. I could literally see the blood flow through his arteries there as I toyed with his smooth erection. "Let's see how you like this," I said as I slapped one side of his tied testicles. The sound of the riding crop's end whipping against his shaved balls reverberated through the whole barn. The sting of it made. This year, Ryan had turned sixteen about two weeks before I turned eighteen. We were going to spend seven days in a static caravan where I'd need to share a cramped bedroom with him.Even on the days the group didn't meet, I was still giving myself at least one orgasm a day, so I'd need to be sneaky. What's more, my period was fast approaching; I'd always feel horny in the days leading up to it and masturbation helped take the edge off any cramps. Fortunately, I'd shared with Ryan on many. ." He said."Come on...let's go home...it's getting dark.."I said,"Duh.." He said walking with me to the car...He was living with me for a while because his parents were taking care of private matters, and didn't want to expose him to some stuff...so since I moved out to my own place, he's with me....it've been a long time ever since we tried doing something, of course...we would kiss eashother eventually...but nothing major since we both didn't have enough time...that's how my routine ended up.
