Did673 - Fuck My Sister

Kelsie found out her sister Kimmy was fucking her boyfriend. She planned her revenge. One day Kimmy returned home from work early, Kelsie had arranged for that. Kimmy was a horny little slut and Kelsie knew her pattern. She knew without an afternoon fuck Kimmy would go to her room to masturbate. Sure enough Kimmy did just that. Kelsie waited to hear the moans before she entered the room sporting a huge strap on cock. Kimmy was embarrassed at first but Kelsie assured her it was fun and since it was a strap on it was not like they were doing anything wrong. Kimmy took her clothes off and let her sister fuck her hard. Kelsie told her to get in doggystyle position. She pounded her with anger as she pictured her slut sister with her boyfriend. She took a rope and put it around Kimmy’s neck pulling it tight. Kimmy tried to get it off but could not. She began to gasp for breath. Begging Kelsie to let go. Kelsie continued with the breath play until Kimmy slumped over, unmoving. Kelsie smiled and continues to fuck her motionless sister.
