Greatest common Divisor

Tacchan is my smart, athletic and cool lover. Yesterday, we had dinner together, bathed together and had vigorous sex at his house... but I couldn't hold back, and after three rounds, he got super mad at me and said, "At this rate, I'll be a virgin forever!!! Stop complaining and let me shove it in you after one round!" That's asking for the impossible~ I'm not satisfied until I've done it about three times!

Included one-shot: Kemomimi! Usamimi? Mimimimimi!?
