You walk in on Mommy while she’s having some “special alone time” – you share your curiosity and she answers your questions and tells you about masturbation, vaginas, sex…etc. But Mommy, why did Dad tell his friend that you give the best blowjobs because of your special tongue? One question leads to another, which leads to Mommy sucking your cock and riding you until you cum inside of her. Oops! Well, Mommy was thinking about giving you a little bother or sister anyway.
