My stepson came to me in the middle of the night and asked to lie down because my husband was on a business trip. I just asked him not to disturb me while I was reading a book. After a while he started to fidget and when I removed the blanket I was surprised that he was jerking off in my bed! I just wanted him to calm down faster and decided to help him cum. I didn't even notice how he was already fucking my mouth and suddenly cummed in it and a huge amount of sperm flowed right onto his penis. But I didn't cum! He has to fix that
