[Poriuretan] My friends' Sister [Uncle Bane]

Mamoru drops by his friend Kazuya's house only to find him gone—and the friend's sister fast asleep on the couch, her pantyhose-sheathed ass too tempting to resist. Caught red-handed fondling her breasts, he braces for fury, but she flips the script entirely: pinning him down, teasing him about what a naughty boy he is, and demanding he confess what he really wants from his friend's Onee-chan. What unfolds is total femdom surrender—her huge breasts smothering him as she grinds on top with a fanged grin, stroking and riding him until he's begging her to stop, right up until she's purring that he came quite a lot inside her.
