My sister, seeing I wasn't popular with women, slept with me. Of course, in the end, she slipped in and ejaculated inside me! 17 IENF-328

I was tutoring my sister when I fell asleep from exhaustion. When I woke up, I was amazed by what I saw under her skirt. I have absolutely no luck with women, and seeing her lewd pose really made me want to masturbate. But I got caught. She took pity on me and let me have my way with her bare butt... Who knew that after some hesitation, she just slid in and fucked me until I came inside!
