DVAJ-690 "Hurry up and suck it!" I've been abstaining from masturbation in an effort to get pregnant, but when my wife's sister seduced me I couldn't hold back and got a full erection...but she kept teasing me to the point of orga

Description

I'm on a masturbation abstinence in order to try to get pregnant with my wife. My wife's younger sister Azu, who knows about this, seduces me and induces an erection! I try to endure it, thinking that my wife will find out... but my cock is at its limit and can't resist, so Azu gives me an air blowjob where the tip of her tongue barely touches it, and she teases me by licking the tip of my glans out of her pants, finding my reaction of agony amusing and not taking it in her mouth at all! After being put off many times, my desire to ejaculate gets stronger than my reason, and she says, "Hurry up and take it in your mouth!" and she teases me, saying, "Do you want me to take it in your mouth? Don't you want to have a baby with your sister?" My cock becomes stupid and I ejaculate repeatedly with weak stimulation, ruining my ejaculation, ruined orgasm, NTR! Ah... my pregnancy efforts and my mind are gone...
