[casis-kabosu (Aria.)] There's no way I would lose to Onii-chan, right? (Riddle Joker) [raspyery]

Nanami Arihara takes charge of her tied-up brother, wringing flattery out of him before rewarding his honesty with her body. Riding him while he's still bound, she teases him about how warm she feels around him and milks him to a gushing finish that leaves her cooing her love. The sweet, teasing mood carries right through to a comedic finale where the exhausted brother sprints for the door with his siscon sister in hot pursuit.
