At the firehouse and in Egon's lab. Egon is severely constipated and Peter is trying to help him relax.

Peter: Egon, when was the last time you took a shit?

Egon: I honestly couldn't tell you.

Peter: Do you feel like you gotta go now?

Egon: Yes, now can you please get me to the bathroom?

Peter: It's more arousing if you can just go in your pants. Trust me on this.

Egon: I also need to piss very badly.

Peter: Do both in your pants, then. I have and it feels great.

Egon: The thought of shitting my pants is giving me an erection, Peter.

Peter: That's normal, now just go with it.

Egon: Please don't look at me.

Peter: Sure. I'll turn around and give you your privacy.

Before Peter turns around, he notices the massive bulge in the front of his pants.

Peter: Damn, Egon. How big are you?

Egon looks down and feels his crotch. He moans.

Egon: Fuck! I must be engorged.

Egon finally relieves himself, but taking a shit is just too painful. Too much hard and soft shit mixed in. Peter actually turns back around to watch Egon shit himself. Egon also pisses himself, As Peter looks down and sees a forming yellow puddle. Just watching Egon gives Peter an erection.

Peter: Is it weird that you're turning me on right now?

Egon: Shut up, Peter!

Egon just keeps grunting and pushing. Peter isn't sure how much room is left in Egon's briefs, by the size of the bulge.

Peter: You want me to get Janine?

Egon: Why?

Peter: I'm sure she can relieve your erection. I mean, you're probably near the edge of ecstasy.

Egon: Janine can't see me like this.

Egon continues to grunt and push and Peter watches as the bulge gets bigger.

Egon: Can you just leave me alone, Peter?

Peter: No, Egon. I wanna fuck you and bring you to the edge of sexual ecstasy.

Egon: Did I hear right?

Peter: Yes, Egon. You always been super fuckable to me.

Egon: Maybe when I haven't shit and pissed myself, Peter.

Peter: No, this is the perfect chance.

Egon, finally done is exhausted and collapses to his knees. Peter kneels down and decides to not only comfort his friend, but to take advantage of him.

Peter: Now the fun part is to sit in it.

Peter pushes Egon back slightly to where Egon feels all that poop spread against his backside and between his legs. He pulls Peter on top of him, wrapping his legs around him and shouting in ecstasy.

Egon: OH PETER! OH PETER! FUCK ME! FUCK ME RIGHT NOW! I NEED IT!

Peter: You don't even have to ask.

Peter closes in and kisses Egon on the lips. Egon deeps the kiss, by inserting his tongue in Peter's mouth. Peter grinds his erection against Egon's. Peter breaks the kiss long enough to start undoing his uniform and Egon's. He manages to strip Egon down to his soiled briefs.

Peter: I'm gonna have fun fucking this dirty ass.

Egon: (delirious, confused) Why are you talking?

Peter: I'm gonna turn you over.

Peter manages to move Egon into a doggy-style position. He slowly pulls down Egon's soiled briefs, revealing his poop-covered ass. Peter gets his hands and cock dirty, by grabbing Egon's hips and positioning his cock to enter Egon's ass. He slowly penetrated Egon's ass, making Egon moan loudly.

Egon: How big are you, Peter?

Peter: Our dicks are pretty much the same size.

Egon: Oh, good.

Once Peter's dick is all the way in Egon's ass, he starts thrusting, pushing himself in and out of Egon's ass slowly and eventually picking up the pace when Egon screams to be fucked harder and harder. Egon uses his right hand to jack himself off while being fucked from behind.

What neither of them counted on was to have Winston, Ray and Janine walk in on the sight of Peter butt-fucking Egon's poop-covered ass. Egon and Peter eventually orgasm at the highest level of sexual ecstasy. Then they turn around at the sound of Janine's shock of utter disgust.

Janine: Oh my gosh. Have you seen anything more disgusting?!

Egon is too exhausted to care, but Peter? He has a few works to say.

Peter: Hey guys. Hey Janine.

Now Peter collapses onto the floor with exhaustion. Winston, Ray and Peter look back at each other.

Ray: Did you just see what I saw, Winston?

Winston: Nope.

Janine: That doesn't bother you guys?

Winston/Ray: Nope.

Winston: I have more of an open mind.

Ray: Same here.

Janine: Ugh!

Janine stomps her feet and leaves the room with Winston and Ray. Eventually, Peter and Egon made it into the shower to clean up.
