My sister walked in on me and son
My son and I were going at it at my place. I had some plans to meet my sister earlier but as she wasnt picking up the phone i thought she ghosted me. Thinking that my sister was out the plan we thought we had the place to ourselves. We put some music on and my son started facefucking me against the wall. The vibes were good, he had me pinned on all fours with my face into the bed shortly after and I was moaning because his cock was hitting the spot. I'm not on birth control so when he was getting ready to finish he flipped me to the edge of the bed with my face hanging off the corner. He was fucking my throat ready to finish when my sister walked in, immediately she closed it and walked away. I don't know if my son found it hot but he unloaded an absolute shit ton down my throat before I could react. We haven't talked it about since and I am super nervous...
