My son walked into my bedroom with a massive hard on just as I had finished getting dressed to go out with his father. What an inconvenient time for him to ask for mom's help with his huge cock, as his dad was in the shower barely 20 feet from us!Dammit we need to hurry! I stroke it and lick it but I struggle to get my mouth around his beautiful hunk of sweet meat. I know how much he needs to cum. HURRY!! OMG his dad will be out of the shower any minute! I am so turned on! We have to be so quick and quiet. I cannot stand it anymore so I take my clothes off and get on top of it. Mmmmm Always so good!!! I tell him NOT to cum in me as his father likes to fuck me before bed every night and surely he will suspect something.After I CUM on his big cock  I continue  stroking and tell him to hurry but he HAS to come in my mouth so we don't make a mess. Once he finally shoots his load into my mouth I tell him to leave before his dad gets out.I think we will order in tonight instead. I'm tired ;-)
