Relieving Stepbro's Blueballs

Anastasia knight seemed to be innocently watching videos on the couch, but when her bro saw her hands fidgeting underneath the blanket he knew something weird was going on. He lifted the blanket to catch his sis twiddling her twat. He enjoyed watching, until stepdad started walking into the room. She had to stop or else they would get in trouble. The next day bros girlfriend left him with some heavy blue balls. This was great for Anastasia because she needed to borrow his car keys. She offered to finish him off for the keys. She began to jerk him and just before he could nut someone interrupted. Later that day sis went to go grab the keys but she didn’t even finish the job! bros balls were still blue. She got down on her knees and finished off bro like a good sis should. He finally relieved his nut all over her face and she got handed the keys. Thats a good little slut :P
