I can't remember the name of the manga or of the characters but i do remember one scene. The uke pushes down the seme (who is very suprised) and stars kissing him. The seme trys to get away but his knee brushes the uke crotch. The ukeof course gets hard and then the seme starts to think the uke looks sexy. Scene end! Sorry, that's all I can remember but if you can figure out what manga it was you have my enternal gratitude and undying love (for awhile at least ;P).

hrm....
I'll take a wild guess, and throw in Living for Tomorrow. Similar scene..

thank you!
