While my girlfriend is away, her innocent yet aggressive little sister comes to me every day, secretly giving me creampie after creampie. She mischievously snuggles up beside me, whispering in my ear, teasing me with the same tempting words over and over: "Big sister won't give you bareback, but I can do it for you~" Each time she says it, my self-control crumbles a little more. In the moments when my girlfriend isn't around, I've ended up shooting creampie after creampie deep inside her.
