When they do get back to the car, the ride back to the firehouse was interesting. He didn't wanna sit in his poop, cause it would make a bigger mess. He laid in the backseat with the windows open on the way back to headquarters. Can he blame the other ghostbusters for not wanting to smell his stench? No. Back at the firehouse, just as Peter is the last to go up the stairs, Janine notices the bulge in the back of his pants and laughs.

Peter: It's not funny, Janine. I'm having a bad day.

Janine stops laughing.

Janine: I'm sorry, Peter. I didn't know it was serious.

Peter gets to the second floor and on the way to the bathroom, he goes passed the beds and by surprised, is pushed down on his bed by Slimer. Peter felt all that poop make an even bigger mess, as it squished against his backside and between his legs. He didn't shout at Slimer, cause he didn't want the attention from the others.

Peter: Slimer, why did you do that?

Slimer laughs, but stops when he sees Peter crying.

Slimer: What's wrong, Peter?

Peter: I pooped my pants really bad, Slimer. I was gonna get cleaned up, but then you pushed me and you made the mess even bigger.

Slimer: I'm sorry, Peter.

Peter was vulnerable, so anything could happen. Slimer looked between Peter's legs and stares at his erection. I mean, Slimer had seen Peter showering, but never seen Peter with an erection. Slimer may be a ghost, but he hasn't forgotten what it was like to be human. Especially when he traded minds with Egon for a few hours, which gave him new sensations.

Peter didn't expect Slimer to just cup Peter's face, with his slimy hands and kiss him on the lips. Slimer looks back at Peter, who's lips are covered in slime. This time, Peter didn't react in disgust.

Peter: Can you do that again?

Slimer shrugs and kisses Peter on the lips. This time, Peter didn't let go of Slimer and forces his tongue into the ghost's mouth. He even takes Slimer's right hand and places it between his legs.

Peter: Feel how hard I am, Slimer.

Peter breaks the kiss long enough to undo his unform, unzipping it down to his crotch. Slimer watches as Peter wrangles out his nine-inch, uncircumcised cock.

Peter: Slimer, can I ask you something? When you were alive, what were you like?

Slimer: What do you mean?

Peter: What did you look like?

Slimer: I was a pretty, pretty girl.

Peter: A girl, huh? Explains why you kiss me so much. Would you like to sexually please me, Slimer?

Slimer: How?

Peter: We improvise. First, we start with kissing.

Peter kisses Slimer and sticks his tongue in his mouth. The kissing then leads to Peter using Slimer's hands to caress his chest and then down to his exposed cock. Slimer stops kissing Peter and starts playing with Peter's cock. Slimer isn't sure what else to do with it.

Peter: Can you suck on it without biting it? I mean, I don't want you to think my penis is a very big sausage.

Slimer: Okay.

Peter puts his cock in Slimer's mouth and since Slimer has a big mouth, the ghost is capable of deep-throating Peter's huge cock. Peter throws his head back and moans, just as Slimer's tongue caresses the underside of Peter's shaft.

Peter: Fuck, Slimer. That feels so good.

When Peter reaches ecstasy, he cums inside Slimer's mouth. The other Ghostbusters happen to walk in and catch Slimer licking the cum off Peter's dick like an ice cream cone. They also can't get passed the stench still coming from Peter.

Winston: Oh my gosh.

Peter startles, covering himself up with a blanket.

Peter: It's not what you think. I mean, please don't judge me.

Egon: Didn't you say you were gonna get cleaned up?

Peter: Yes, but then I ran into Slimer and I was vulnerable.

Ray: I'm worried about you, Peter.

Egon: I didn't know you could have sex with a ghost.

Peter: Well, you can.

Winston: I guess we'll all be talking about this for a long time.

Peter does get cleaned up and I don't know why Ray cares. It's not like he hasn't gotten a blowjob from a ghost.
