I bet she’s happy to see such a big cock. Are you taking in all of her enthusiasm for cuckolding? Does her interest and arousal turn you on? If watching her grab his penis and start sucking it gives you a boner, you’re a cuckold.
She is pulling that cock towards her bed. She’ll keep her hand on it until she spreads her legs and he slides it into her fuck hole where it belongs. She wants that cock. Cuckolds see their wives enjoying other men’s cocks as part of their lifestyle, it’s awesome.
