Silent Betrayal, Loud Revelations

Your Step-Mommy (brearose) is throwing a house party and invites you and your Wife, along with all of her Friends. Your step-Mom's best friend starts chatting with you, and the comments get flirtier and flirtier as the night goes on. You find her attractive and can't help but to get an erection. You decide to head upstairs to try and escape her and calm down your boner. The door squeaks open and there she is, tempting your infidelity further. She is practically begging you at this point, telling you that "you could do so much better than your boring cunt of a Wife." You love your Wife... but your step-Mom's Friend is correct. You'll never get an opportunity like this again. Your hard cock gets the better of you, taking control of your brain and you can't resist cheating on your Wife and emptying your load inside of her. You lie on the bed; cock still rock hard, shocked and disappointed over what you have just committed - but equally confused and suprised that you're still horny and that your cock is still standing to attention. You could easily have gone for round two but she has gone now, scared that the two of you would get caught. But don't worry, Step-Mommy has heard about your huge cock and she will make everything better...
