My sister is in town, she's staying at my place for a week while shes here. Just so happen her plane got in a little earlier than expected. She went straight to my home and let herself in.. while I'm out running errands. I use to brag to Aubrey (my sister) how good my boyfriend fucked me.. but i had no clue these stories were turning her on & she wanted his dick too. He's napping on the couch when Aubrey starts sucking his cock, he wakes up & confronts her.. They decide to keep it a secret. ;) With a nice cum shot at the end.
