Oomiya and I are childhood friends.

The extremely taciturn Oomiya and I have been together long enough that I've become able to tell what she wants to say. When we do homework together, I've even learned how to tell when she begins to lose focus, and from that — exactly when she needs to take a toilet break. And just like that, as she stood up to go to the toilet, a vibrator fell from her skirt and even that I... don't understand!!!

I'm stunned at suddenly seeing her sex toy, and Oomiya goes on the attack with the admission "I've thought about forcing myself on you...", followed by the vulgar sight of her long legs squatting while she's trying to insert my dick! I don't understand a single thing that's happening anymore, but I know this feels good!!
