[mimamoriencyo] Little Sister Masturbating With Onii-Chan's Dick [Full Color]

A concerned little sister can't sleep, so when her tired onii-chan offers to help her rest, she seizes the chance to pull him onto her lap and grind against his slumbering cock. With her petite, flat-chested body bouncing eagerly on top of him, she bites her lip and stifles her moans while he drifts in and out of sleep. The tension spikes the moment his eyes flutter open, catching his dear imouto in the act and turning her tender "medicine" into a very awkward confession.
