You (my son) are sad because you do not have a date for the prom. He asks me (your mom) to go with him instead, I agree of course because I do not want my son to miss out on this experience. We go and dance together but then you start flirting with me, trying to feel me up... I stop you, but I do like the attention since I am not getting much from your father so I start giving in to the scenario, flirting back, kissing you... We go to the bathroom where I suck your cock. You're nervous about getting caught so we decide to go home. We must be quiet because we do not want to risk waking your dad. He does, inevitably, wake up. We try and explain at first but then give up and just continue fucking as I tell him I need a big cock like our son's not like his pathetic little dick. You tell me to suck your cock again before you take over to stroke it until you cum all over my face.
