My sister, seeing I wasn't popular with women, slept with me, and of course, she ended up ejaculating inside me! 16 IENF-295

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 buttocks... Who knew that after some hesitation, she just slid in and fucked me until I came inside her!
