Step-Mom Fucks Her Huge Step-Son & Cucks His Tiny Step-Bro

Your two step-sons have been fighting and you're trying to work out what the argument is about. Your older step-son says his younger step-brother has been making fun of him, saying that because his penis is so much smaller than his that no women will ever love him, not even step-mommy. You're shocked by this and try to calm him down, but it's clear that the only way to solve this is to have him show you his dick. He pulls out a tiny 2 inch willy. You stifle a laugh, but assure him that there's nothing wrong with it. You then show some cleavage to try and get it hard, it grows to 4 inches and you say that that's a totally fine length for plenty of women. You tell your older step-son that he's allowed to masturbate to Step-Mommy's boobies this one time because she got him hard, and right as you do your other younger step-son pulls out his massive cock. It's not even hard and it's way bigger. You're immediately gobsmacked, you stare at it for a moment before instinctively starting to stroke it, then progress to sucking it, and eventually fucking your younger step-son's enormous cock. As this happens, you try and encourage your smaller, wimpier, older step-son, saying things like "just because step-mommy prefers a big cock like your step-brother's doesn't mean there's anything wrong with your willy" and other kinds of small penis encouragement, but by the time you're fucking him you're basically fully demeaning him, cucking and making fun of him for wanking to his younger step-brother fucking his own step-mother. As it ends, your older step-son asks if he can cum on your face, and you begrudgingly allow it, but he just dribbles on the floor. You laugh and say "let's show you how a REAL cock cums all over Step-Mommy" before your younger step-son jerks his big cock and blows a huge load over your face.
