Incest Seduction/Put some oil on Kim's bum

From Create Your Own Story

With a grin, you hold the bottle over your sibling's exposed ass and give a few quick squirts. She starts to squirm as soon as the volley hits her, but she doesn't exactly have anywhere to go.

"Ryan! You're not supposed to put it on like that!"

"I thought I was the masseuse?" you tease.

"Ewww, it's running down my..." Kim trails off. She fumbles around under her towel, then you see her thighs part slightly. You catch merely a glimpse of her smooth hairless vulva before her hand pops into view from underneath her to cover herself. Is she really still hairless down there? Maybe she waxes. In any case, catching a glimpse of your sister's pussy has your dick twitching again, as if this situation wasn't erotic enough. You watch as a runny glob of oil appears from between her buttcheeks and runs onto Kim's fingers.

You sister sighs in exasperation. "Well at least... rub it in, or something."

Gladly! Spread the oil around Kim's ass for her.

At least try to remain somewhat chivalrous. It's better if Kim rubs around there.
