My Girlfriend and her sister

Mike had been going out with seanna for over a year and all that time her sister emily would always flirt with him. She was about 14 and seanna was 17. he never thought much of it and usually brushed it off, but one day it was just too much.

Mike went over seannas house for dinner. It was nothing out of the usual something he had done a thousand times. Tonight emily was dressed a little different. She had on a very short dress and her boobs had seemed to grow since the last time he saw her. Mike couldn’t help but stare at her. As the night went on mike tried hard to forget about emily and focus on his beautiful blond girlfriend seanna. After dinner her parents decided to go out. They trusted mike and seanna enough to leave them home alone with only emily there. So after cleaning up mike and seanna headed downstairs. They turned on the tv and started to make out after a couple minutes. Things progressed and mike started to massage seannas pussy through her yoga pants. She was very beautiful and he was very turned on but he couldn’t help but think about emily. Her round teen ass and her beautiful brownish hair. Mike focused again on pleasuring his girlfriend, but as she reached her hand into his gym shorts to start stoking his dick, he just couldn’t keep his mind of her younger sister. Imagining her small teen hand stroking his cock. Mike closed his eyes and just pictured emily when seanna whispered something in his ear.

“I have a surprise for you” she said seductively.

Mike thought it would just be another one of her new bj techniques but when she told him to open his eyes he saw seannas 15 year old sister standing there in a purple bra and thong.
