She is asleep on the daybed. She asks where is your wife. You and your girlfriend are the only two. She tells you how much she loves you and how much she values you. Then she asks if you can answer a question. She doesn’t think it will be strange, as you and she have always been good friends. It’s not harmful. She asks for a boobjob and takes off her bra. Your first reaction is to be confused. Her breasts seem so perky. You tell her she’s fine. She’s noticing that your pants are getting a little tight. She wants to see it because she finds it funny. Why not? She unzips it and she sees your massive cock. She just can’t stop sucking. It’s not worth it to cheat on your spouse with your sister. She warns you not to touch her. She’s not taking the pill. She’s so hot and tight. Her dirty talk is the best. You are unable to stop yourself because she is riding you hard. You have a sister inside you…
