Boku wa Imouto Sen'you Semen Tank

My busty little sister owns me... owns me and ALLLLLLL my cum! She will squeeze me dry to the very last drop! I cannot resist her even though I made try... it just feels so good to splash my cum all over her. And she doesn't even bat an eyelid!? She loves my cum, she drinks my cum, she bathes in my cum! That's why I cannot even let my guard down while I sleep, or take a shower, even when I'm eating! Anytime, anyplace, anywhere! She even makes me dress as a girl, takes me to the park and rapes my ass. (Not that I'm complaining or anything.)
