여고생 의붓여동생 엉덩이에 쑤셔넣었어

One day I visit my best friend at his house to talk for a while, but the moment I get home he goes out to the store and leaves me alone with his stepsister. He entered her stepsister's room and told her to fuck while we're alone. She says yes, but that she put it up her ass since she is afraid to do it through the vagina because she is not taking care to prevent a pregnancy.
