I want to know what happened between kuroki and sensei(≧∀≦) could kuroki be the bottom or could he be the seme Σ(っ°Д °;)っ

Oh that's easy. (mind you this is just my thoughts)
After having sex a few time. Switching stems between the pair. Kuroki because something of a more sadistic uke and sensei his pleasure slave. There adorable together.
