"What?! You take baths with your sister at your house?!" After club activities, I borrowed the bathroom at my friend's house, and to my surprise, his older sister, Nanao, barged in while I was bathing! Apparently, it's normal for siblings to bathe together in this house, but I was pressed against her defenseless, massive breasts in the small bathtub! What's more, she even peeled back my foreskin and washed my dick for me! Unlike her real brother, my dick was rock hard, and she gave me a blowjob! I begged the kind, easily swayed older sister for sex! I stayed the night at her house and, while my friend wasn't looking, I devoured her massive breasts and came inside her! Sister, my dick's acting weird again… I'd like you to fix it…!
