On the fifth night I was thinking about jacking off more than ever. I had my hand on my throbbing dick and it was all slick with my natural lube and I... was thinking about getting up and going to the latrine and beating off there in the dark.But for some reason I just started to rub on my dick while lying in my sleeping bag next to Sandy. I figured that I could get away with it and I had a bandana to cum in, so what the hell. I turned on my side facing away from my sister and began to slowly jack. Rhonda went behind me and began working with the laces in the back. She started in the middle and what had been snugness around my waist was soon tightness. She went to the top of the laces next and as she drew than tighter and worked down toward my waist I found it was difficult to take a deep breath. Next she began work at the bottom and it first drew my thighs together and then the tightness spread through my hips and buttocks. I didn't notice too much change in my groin area but it was. Slowly,erotically,she busied her hands soaping her damp and wet skin,fondling her tits, she again caught the man outside, almost feeling the lust crawling all over him,slowly she spread out her legs open wide, and touching her soapy skin,fondling the apex of her vagina, and let some moans...out enough to be heard by the man outside on a semi arousal..She was in progress in what she was doing ,luring the pervert man out from his sanity,stealing it away from him,touching her clitoris. Mating with the opposite sex is considered for procreation only.Yuatan introduced Settna and Pittna Sordii.
