Yamada's First Time: B Gata H Kei

Suddenly So Close in the Darkroom! Kinda Dangerous Club Activities?! / Passionate School Festival! I, Yamada, Will Be the School's Queen!

When Yamada learns of Kosuda's membership in the photography club, and finds out that he is going to develop a few pictures in the dark room, she turns that into a sneaky scheme to "obtain his golden cherry." There, as Yamada accidentally trips the plug to the red dark room lights, Kosuda accidentally touches her bare breasts, but has no idea what he was touching. Disappointed, Yamada runs out of the room after Kosuda finds the switch to the normal room lights, but he catches up with her in his bicycle and offers her a ride home.
