If there a situation where the MC wakes up only to find Stephanie was no longer sleeping next to him, and he goes looking and peeks inside Arnold room to see them having sex...
MC: Steph! What are you doing?
Steph: I was going to the kitchen for a glass of water and I heard Arnold jerkin' his gherkin.
MC: Yeah, so?
Steph: Well, I could tell he was having trouble finishing, so I offered to help. Is this alright?
MC: Well, I guess so.
Steph: Go ahead, Arnold, keep fucking me! MC says it's OK.
Arnold: Aaaahhhhh!
Steph: Is it OK for Arnold to dump his wad into my waiting pussy?
MC: I don't know, we haven't talked about this yet.
Steph: Hurry, MC, he's getting ready to nut! Can you make up your mind?
Arnold: Aaaahhhhh! Almost there, Steph!
Steph: Hang on, Arnold! MC! Yes or no!!!
Arnold: Steph! I'm getting ready to cum!!!
Steph: MC! Look what you're doing to my poor Arnold! Can Arnold cream pie your wife's pussy?
Arnold: Aaaahhhhh! I'm cumming!!!
Steph: Go ahead, Arnold! Give me your baby batter!!!
MC: We have to talk!
Steph: I have been talking, but you haven't given me the answer that I want!
Arnold: Aaaahhhhh!
Steph: Keep fucking me, Arnold! Fill his wife's pussy with your man juice!
MC: Well, go ahead then.
Steph: Too late, MC! How do you feel, Arnold?
Arnold: Great, just great. I'll be able to sleep now. Thank you, MC!
MC: Right.
