Blowjob ! 20 year old friend from the stepson's

My stepson had friends over to gamble. Anyway, I was lying in the tub and one of his friends came in, he was really shocked that I was lying there in the tub and said he only wanted to go to the toilet because the guest toilet is currently occupied. I just said keep calm and I could give him a bubble. He was a little hesitant at first, but then quickly got down to business. His hot cock got blown off nicely.
