Walking in on my girlfriend, a petite teen, wasn't what I expected. Her back arched, eyes closed, she was lost in pleasure, a vibrator humming between her legs. She tried to hide it, but I saw it all - her wetness, her desire, her betrayal. She begged me to join, to watch her oral exploration, but I was too angry, too hurt. Yet, as I stormed out, I couldn't deny the heat in my loins, the temptation to return and claim her forbidden pleasure.
