You’re spying on your futa sister jacking off. She notices you in the door and is really annoyed at you. She has a HUGE load to cum and she’s right in the middle of it. You won’t leave despite her asking to. You ask to watch, she’s grossed out since you’re her bother. You say you can probably cum more than her, she can’t believe that considering the size of her dick. You want to have a cum competition, she’s pretty confident she’s going to win so she agrees. You both start jerking off. She says its actually pretty hot and will make her cum even more. She dirty talks you a bit, teasing you with the fact her cock is so much bigger than yours, how she can play with her tits while she’s jerking and you only have your hand. She tells you she’s about to cum and to watch this. She closes her eyes to cum and doesn’t notice you’ve gotten closer to her. She cums on her own face, a pretty big load. She opens her eyes and realizes you want to cum on her face too. She’s pushing you away, telling you to sit down when you cum the biggest load EVER all over face, hair and body. It comes pooling out of her pretty mouth. Well, she says, she guesses you win the challenge after all.
