I'm your college-aged step-sister. We're chilling at home, I'm working on my laptop and you start asking about the donuts that step-mom made earlier and I immediately get annoyed.

You were supposed to come home and eat the donuts with us but you didn't. You acted like a little asshole but now you want some? Well, we already ate all of them.

You keep going on about the donuts and I keep getting pissed off but then remember that MAYBE there's some filling left. I go check and what do you know? Step-mom left some custard in the fridge. I start teasing you asking if you want s...

I'm your college-aged step-sister. We're chilling at home, I'm working on my laptop and you start asking about the donuts that step-mom made earlier and I immediately get annoyed.

You were supposed to come home and eat the donuts with us but you didn't. You acted like a little asshole but now you want some? Well, we already ate all of them.

You keep going on about the donuts and I keep getting pissed off but then remember that MAYBE there's some filling left. I go check and what do you know? Step-mom left some custard in the fridge. I start teasing you asking if you want some and, of course, you do.

I push my laptop to the side thinking that maybe I can get some fun out of this custard thing. I tell you I'll let you have the custard if you earn it... if you play a game... a grown up type of game. It's the same game I play with my boyfriend so you know it's good. You're reluctant but finally give in because of your sweet tooth.

I tell you to get on your knees and proceed to take my clothes off. You start freaking out, not really understanding why I'm getting naked for some custard. I realize you're clueless so I start explaining the game and where exactly the custard will go. You freak out even more saying you don't want to play but I reassure you and tell you to trust me.

I give myself a fat custard enema right in front of your sweet face. The custard goes up my ass and the pressure starts building. Before you know it, I feed you your beloved custard. Is it sweet just like you wanted, lil step-bro?

I push and push, the custard coming out of my pink asshole, pouring down my ass as I fart right in your face and the sweet smell of vanilla hits your nostrils. I tell you to lick it all up as I keep spraying custard everywhere while I rub my clit. My fat pussy is so wet, drooling thick pussy juice, flapping left and right as I rub it and cum on your face. You ask me what's going on as post-nut clarity kicks in and I realize that I just came on my little step-bros face!!!! I try to reassure you saying nothing happened but then I hear step-dad coming upstairs!! I quickly order you to go take a shower and tell you I'll clean everything up.
