I couldn't believe it, of course I wanted to, my cock was aching it was so hard, I said yes, and swallowed hard. Steph pulled up her T shirt and spre...d her legs, after taking a sip of wine. She started to rub her clit right after putting a couple fingers inside of her pussy to get them wet, I really couldn't believe this, her pussy looked so fine and she was letting me, her brother, watch.As she got turned on, her voice got a bit husky and she asked if I was enjoying the show. I had to tell. The only sound in the tent was Darlene's soft breathing as she cuddled close, but still I felt a presence."You look beautiful tonight, Zo," I softly greeted her, her image waltzing through my mind. I wondered what she thought of all this. The road trip. A different girl every night. "I miss you."I've never been certain of the afterlife, but I hoped their was a heaven for Zoe's sake. "G'night." I lay my head back on the pillow and closed my eyes.I woke when Darlene kneed me in the. I woke up again, only on my back, I felt a warm wash cloth on my dick and balls. Mom kissed me, then gathered our clothes and we dressed in the dark room. She went out first to go shower. I went out and sat down to rest. She walked by me later, fully dressed and paid no attention to me, like nothing had happened. We never said a word about it, outside the dark room.Two days later I was getting ready to go hang with my buddy’s and mom whispered: (….”when you get back, why don’t go in the dark. So i continued to fuck her pussy while the vibrator was deep inside of her and as she wanted i went balls deep in that pussy and i picked up the speed and went faster and harder but after awhile i switched it up i put the vibrator in her pussy and my cock in her gapped ass n we continued goin at it for a least another 10 to 15 mins.then i felt her climax coming on so i pounded her ass as hard as i could and she finally let loose OHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH.
