Go on with it

Although hating every second of it, you obediently make your way to her, kneeling in front of her... thing.

"Don't look so sour. Think of it as just a really big clit that you're sucking on." It might had effect if there also wasn't any balls, or an urethra, or if it didn't smell like a man's...

You grunt, trying to keep all those thoughts out of your head. Maybe if you just close your eyes then it won't be so bad. You soldier through the smell and touch that thing with your tongue. You have never tasted a man before so the sensation is fairly new. It's salty for some reason. A bit more of her length goes inside your mouth and before you notice you are obediently sucking her cock.

Still with eyes closed, you hear her moan fiercely. Your nose scrapes the thick hair on her crotch. The wet noises that you're making, the weight of your chest wobbling back in forth, the feeling of dick filling your mouth, how it tastes. All of it is so strange for you. Those and some weird tingles you're getting down there.

"Oh my God! That feels amazing! How do you guys don't go **** everyone with this thing?!" Your sister surprises you by grabbing your head and violently forcing you into her. You gag as her glans hits the back of your throat.

You don't know whether to be terrified by the way she's acting or embarassed at the fact that you're being face-fucked like a good little slut. Something twitches down there as you are giving head. You bring a hand to your crotch only to feel something sticky soaking the fabric of your underwear.

Can you even consider yourself a man if your body is behaving like a cocksleeve like that?

"Ughhh, I can feel something coming bro! Don't stop! Don't stooaahh..."
