She was lying on her back ---- naked. I almost fell to the floor when my knees turned to jelly, I stopped breathing, I dropped the towel. I stood there forever holding the sheet high staring at her body, the firm round tits, her flat smooth, stomach and the nest of hair over her sex. My cock which had been half hard when I started for her room exploded to porn star status in seconds. Once the shock of seeing a female nude for the first time in tits my life waned, I lowered the blanket and turned to leave, there was no way in hell I was going to lay down with her in that condition. That moment of stupidity quickly drowned in a flood of hormones that crashed into my blood, there was no way in hell I was going to waste this opportunity. I returned to the bed, picked up the blanket and ever so carefully went to lie next to my nude sister. The bed was shaking from the crashing of my heart, my cock was spitting lubrication and when I grabbed it in Hardcore my fist, it was slick from throbbing knob to my aching balls. I stroked myself slowly while watching Nadine sleep beside me. I'd dropped the towel when I saw her but didn't pick it up again and the longer I lay beside her masturbating the less it mattered that I didn’t have it; as the pressure mounted, as semen filled my erection I rolled to my side facing her. I decided blow my load on her skin and I didn't give a damn what she would think in the morning. My stomach cramped, my cock convulsed and the first pressurized gush of cum splashed on Nadine’s hip. The second landed higher leaving a trail of thick milky fluid across her stomach and pubic big hair. The next three shots covered my sister from bellybutton to the top of her crack. I stared at the white viscous globs of my discharge pooling on her skin and began to feel terror. I had let my hormones control me and now if Nadine wasn't completely brain dead, she would discover what I had done when she woke. I crawled from her blonde bed ashamed; afraid. I stayed in my room the next morning until dad roared at me to get up and ready for school. I hoped against all hope that my sister had already left the house but when I showed my face she said with all normalcy “Hurry up, we'll be late for school” she was waiting to walk with me. In the fifteen minutes we walked we had our normal morning conversation. It was our regular trip to school and I began to wonder if she even realized that she had my cum on her when she got up. As the day passed my trepidation faded and by dinner I guessed that I had gotten away with jacking off all over Nadine. By the time I went to bed blowjob my world was right. I resolved not to repeat my salacious act but I wasn't feeling guilt any more. I woke up with something covering my face, my breath was hot, I was suffocating. I grabbed to remove the blanket but as I came more awake I realized I was feeling terrycloth, a towel. I pulled it off and my eyes opened to look directly into Nadine's face. Unfortunately this caused her mouth to open wider as she tried to blonde cry out in pleasure. It was worth the wait for Brittany to finally put them on. He lasted much longer then he would have thought until he started using more of his weight and strength to pound her into the mattress in the sleeper. Her arms were pulled up in an attempt to blowjob cover her boobs and she was fidgeting her legs as if trying to cross big them. Tina smiled subtly for the first time. I raise my head and look at Eddie standing between my legs. Hardcore ‘Fuck off mum I was listening to that!’ Jill returned shortly with my steak and another Coors. Are you sure you still wanna do this? I will get the use of one of your hotel rooms on every Wednesday night. Did he know I started doing track earlier this year? They giggled and said. The table leg now pushed into her shoulder with Bruno still on tits top of her. Everyone beds down for the night. There were bookshelves. Anyone outside the cabin wouldn't see her dressed similarly to a fancy girl, she was dressed as a fancy girl!
