Your sister is home for the summer, and she's missing her boyfriend.... you peek through the door crack and listen in on her private conversation, I am having phone sex with my boyfriend with my hand down my pants.... You continue to watch. Then I look up and catch you! I cant believe you were spying on me!!! But with my boyfriend so far away and me all horny from the phone sex, will you be a good brother and help finish me off? I even talk to my boyfriend on the phone with my brothers cock in my mouth!
