HUNTA-601 - My sister passed out in the bath, and her wet towel couldn't hide those massive tits.

My sister stayed in the bath too long, so I checked on her and found her passed out naked. I carried her to the room, but seeing her massive chest through the towel gave me an instant erection. As I tried to leave, she stumbled and grabbed my hard-on. The awkward tension melted away as she became aroused by my bulge, eventually devouring me and begging for more all night long.
