Marissa was hanging out with her boyfriend when her sister,  Vanessa,  came in the bedroom yelling about her jacket. They began fighting and he broke them up. All that fighting made Marissa horny and she began sucking his cock. She started riding his cock as she got a text from her friend that needed her help. Marissa stopped in the middle of fucking to go to her friend. After she left,  he began jerking off as Vanessa walked in and caught him. She sat on the bed next to him,  explained that she was eighteen,  and told him she could help him with his blue balls. He was hesitant at first,  but let her suck his cock and then fuck him. She wanted to prove she was better than her sister and she did a good job convincing him. She got man juice all over her face like she requested.
