Mukai no Kuseni EROsugiru?

"Can you feel yourself twitching when I touch you down here?"
Mukai and I are bitter rivals always battling to avoid earning the lowest grade in class. I thought I only saw him as a dimwitted pal of mine, but why did my heart start racing when he scored that goal at the alumni soccer game and when he saved me from that girly girl trying to one-up me? Ugh, why does he seem so hot today? After all that, I couldn't ride the last train to get home and he even offered to stay at a karaoke place all night with me… Wait a minute, why are we in this position? He just put it in and I think I'm already going to come…! He's a fool, but I love him! If you're looking for a lighthearted, overly erotic romance between two silly lovebirds, this is definitely one for you!
