Ok, so here's how I want this scene to play out.
In the first panel I want an anon guy to fondle Ibuki's breasts in the shower while Ibuki slowly teases the guy by playing with his penis from behind. The first picture should give you a good reference.
In the second panel Ibuki gets banged from behind while she moans in pleasure. The anon guy is grabbing her sides and goes at it roughly until he cums inside her. Please use the second picture for reference. Also, Ibuki's facial expression should match the second picture as well as the first.
