When I first went to her house, her older sister, Nene, was there, winking at us with a mischievous smile. A few hours later, when I went to the toilet, Nene's room door was open, and I peeked inside to find her lying on her back, completely pantsless! I stumbled back in surprise, and Nene, noticing me, asked, "Were you peeking?" while sticking her ass out at me with a teasing grin. "You've only been looking at my ass, are you into that? You can lick it if you want." From there, I stole glances at her while she made me lick her anus and gave me reverse cowgirl lessons. Nene's pheromones are just amazing!
