Your brother's best friend was staying over at your house, and he was trying his hardest to work, but you kept distracting him, and teasing him, and seducing him and he was getting very, very tired of it, as well as very, very aroused....but you were his best friend's little sister...he couldn't..

"Iris...stop it....we're just friends....we should stay that way...." He says, but after seeing your sad expression..he sighs and rubs his face

"One kiss."
