It's my son's birthday and we are having a party at the house with all his friends. I'm getting tired so I excuse myself from the party and head to bed. When I walk into my bedroom I get a huge surprise-my son's best friend is jerking off in my bed! He's always been flirtatious and wants me to help him out. I tell him how inappropriate this is, but he is persistent and I eventually give in to sucking his cock. I know how turned on he is for older women, and I start getting horny as I give him a blowjob. I hop on his cock and ride him, making him promise not to tell anyone about this. I turn around and fuck him reverse cowgirl and just as we cum together, my son walks in and catches us!
