Custom Video: It's the morning of your older Step-Sister's wedding and she is trying on some lingerie ready to surprise her soon to be husband with some sexy attire. You are walking her down the isle as your Step-Father left when you were both younger, so you decide to check in on her to see how she is feeling about the big day. She accidentally left the door open and you can see her trying on some lacey lingerie. Instead of doing what any normal Bro would do you stand there in the doorway, watching her. The last time you seen her body was when you were on holiday together many moons ago, and she is just as hot as you remembered. To your surprise when your big Step-Sis catches you, she invites you in to help her. She could really use a Man's opinion on which one she looks the best in. She tells you to close your eyes, but you can't help but to sneak a cheeky peek. The more peek's you sneak the more turned on you're getting over your own Step-Sis. She clocks your boner and tells you how wrong this is, she is disgusted in you. "Don't you have a girlfriend!?" When you tell her the two of you haven't had sex in a while your Step-Sis starts to feel bad for you, this is her special day and she also wants you to have a good day to. Seeing as it's been so long since you've drained your balls she suggests the two of you have some sneaky last minute sex before her big day so you can both enjoy yourselves. You both know committing this forbidden act is very fucked up, but in the heat of the moment all you can think about is each other. Emptying your seed inside of your own Step-Sis is one thing... but the two of you cheating on your partners is one step too far...
