You were drunk when you confessed to your creampie cleanup fantasies. You wouldn't have shared them otherwise. It was far too revealing.
Neither of you said anything about it afterwards. It never came up again. Not until tonight.
Now she's asked the question, though. She wants to know if you still fantasize about cleaning another man's cum out of her.
The real question is, should you tell her the truth?
You can't help but wonder if she'll look at you differently once she knows you want to lick someone else's cum out of her. It's different than watching him fuck her. It's a whole different level of cuckolding.
Still, you want it, don't you? You want to watch him fuck your gorgeous girlfriend. You want to watch his cock stretch her pussy. You want to watch him move in and out of her without a condom on. You want to watch his dick pulse and his balls jump in their sack as he unloads inside her. You want to see her stretched out pussy leaking cum. Most of all, you want her to invite you to crawl between her legs so you can clean up his cum.
Maybe it will end your relationship if you admit that you want it. Maybe she'll see you as some pathetic cum eating cuckold that has no business dating her.
Maybe, though, she'll love it. Maybe she'll get off on her boyfriend revealing that he wants nothing more than to be a cum slut for her. Maybe she'll feed you load after load after load of hot spunk from her freshly-fucked cunt and you'll get to live out all your cuck fantasies.
Yeah, you should tell her you want it. You should admit it. You should embrace it.
Go ahead. Confess to your fantasy. Confess that you want to be a cum eating cuckold.
