I'm abstaining from masturbation for my wife's pregnancy efforts. Knowing this, my sister-in-law Azu tempts me and induces an erection! If my wife finds out... I endure it, but my dick can't resist at its limit. Azu teases with her tongue tip using air fellatio, only pulling the glans from my pants, licking the tip to torment me. She enjoys my writhing reactions but won't suck at all! After being teased multiple times, 'Come on, suck it already!' My desire to ejaculate overrides reason. 'You want it sucked? You don't want to make a baby with your sister?' Provoked, my dick goes stupid, and I explode repeatedly in uncontrollable orgasms of NTR! Ah... both pregnancy efforts and sanity are ruined...
