Another day of work is finally over. Your boss, as usual, complained about your mediocre performance. But you’re sure he had a good reason, you just have to do better tomorrow.
You picked your boy from the daycare and decide to walk with him on the park for a bit. It’s been like this ever since your better half left, but you don’t hold it against them, you’re happy taking care of the little one.
The sun is starting to set, and you decide to sit down on a bench, placing the bag with all the baby stuff on the ground, and resting your boy on your lap for a bit, before heading home. The park is a bit deserted, and most families already left when a stranger approaches you and slouches down pretty close to you despite the size of the bench. “What a friendly fellow”, you think to yourself.
“Good evening, Sir.” You greet him. A mix of sweat and a croth odor invades your nose. The stranger exudes manliness from all his pores, and you do your best not to be impolite and show discomfort.
“Hey, what a cute baby you got there… Give him to me.”
You’re taken aback at the manner he put it, but you figured it’s just his way to ask to hold your boy for a bit. Without hesitation, you hold your boy up as he takes him from you with a firm grip.
“Damn, he’s so fucking cute… How old is he?” The stranger sits your boy on top of his crotch, bouncing him up and down. You haven’t noticed it yet, but it’s big enough to have your boy sitting on it like a leg. You don’t want to assume the nice man has any bad intentions, so you decide to ignore the strange interaction.
“He’s gonna be two in a few days.”
“Fuck yeah, it’s been so long since I had one this small…”
“How old is yours?” You naively ask, misunderstanding his remark.
The stranger ignores you, ripping your boy’s clothes off and unzipping his pants, letting his fat cock out, throbbing under your little baby’s butthole. You only take a quick glance at it, but it’s at least three times bigger than yours and emanates a foul odor that makes you flinch.
“S… Sir, what are you doing?” You manage to babble despite how shocked you are.
“What does it look like I’m doing, you stupid bitch? I’m gonna rape your little baby’s cunt with my dirty pedo cock!” He says so matter-of-factly his bluntness and openness leave you speechless.
The stranger pulls his foreskin back, revealing the source of the smell. His dickhead is coated with a thick and yellowish layer of smegma.
Without hesitation, he inserts the entire length of his disgusting member inside your baby, making him cry louder than you‘ve ever heard. You start thinking about all the times you wanted to do the same thing, but were too scared of hurting him. Now, a stranger took your place without a second thought.
“Ohh yeah, cry you fucking bitch! Cry to your daddy… He’s right here on my side watching you getting fucking raped by a pedo and not even moving a muscle to stop him…” 
He forces your boy up and down his cock violently. You can see blood dripping slightly from the baby’s anus, but despite that, you start getting hard. You wish it were you doing it…
“Hmm, what’s wrong, baby? Am I too big for you? Bet it’s the first time you take cock, huh? Your deadbeat dad never fucked you before, did he? Two years with a fleshlight at his disposal and couldn’t even muster the courage to shove his tiny dick inside it. Look at him, now he’s getting all hard and wet watching a real man take care of his boy. What a pathetic loser…” 
You start rubbing your legs together, half trying to cover your bulge in shame and half trying to stimulate it. You know your boy is under immense pain, and you feel ashamed and humiliated. You start crying out of guilt, but the pleasure you feel from it all dominates every other emotion.
“Ohh yeah, you fucking loser… Watch me cum inside your boy… Fuck… Fuuuuuck!”
He impales the baby balls deep. You can hear the gurgle inside your poor boy’s tummy as it gets bigger and bigger. A loud cry from him, then silence. Cum starts pouring out of his anus and mouth. The stranger keeps going, not caring that the boy is completely unresponsive. You don’t even know if he’s still alive.
You sob and shake as the violent sight puts you on the verge of cumming. He then plops his fat cock out. Cum gushing everywhere, some of it with a slight tint of red. You can’t contain yourself anymore.
“C… Can I have my boy back?” You ask hesitantly. Not even knowing if you’ll be capable of doing what you want despite how hard your dick is throbbing.
“Pff… A loser like you doesn’t deserve a tight rape meat like this one. I’m his daddy now…” He gets up, trashes the baby bag, empties it, and shoves your boy inside. He then cleans his own dick on your shirt and face, smearing a mix of smegma, pubes, cum, and blood on you. The humiliation is too much for you. You start cumming uncontrollably, wetting yourself from crotch to shoes.
“What a fucking cuck… Don’t worry, I’ll send you a pic of his gaping asshole once in a while so you’ll know how well he’s been treated, hahaha…”
You’re left by yourself in the dark on the park’s bench. Diapers, a baby bottle, his pacifier… All over the ground. Cum everywhere. The rancid mix of the stranger’s and your baby’s scent on you. 
And yet, you feel a bit relieved. Maybe this is better… You wouldn’t be able to do it anyway. Now, at least your boy will be taken care of by a real man. A big, dirty, manly pedo, who will rape him and remind you constantly of how much of a loser you are.
You start to get hard again…
