Offer him a room + "Extra" service

"How about we celebrate today's success a little more? You are also welcome to spend the night here. It's on the house, as a token of my gratitude."

"CeLeBraTE? I lOVe To CeLeBraTE"

"And have you seen the redhead? She'd party with you too."

"ThE PreTTy wOMaN? REaLLy?"

"Sure dude. And more than that. If you want, she'll sleep at your place tonight."

"YoU mEAn..."

"yes."

"ShE is..."

"yes."

"GoNNa tOUch mY DInGelInG?"

"Um. You could say that, yes."

"THIs is tHe beST dAY of mY lifE!"

You take him to his room and tell him to wait.

You go to the bedroom, where Mira is already waiting for you. She lies on the bed dressed only in her nightgown and looks at you lustfully.

"Hey honey, I thought maybe you'd like to have a little after show," she says, pulling her nightgown up, enough to give you a view of her pussy.

"Great, now she's horny too. That bard has more luck than brains, that's for sure."

"Sorry honey, but I guess you'll have to celebrate the after show with the bard who's staying over tonight."

"So you did..."

"...Yes I did. It shouldn't take too long though I'd bet money he's a virgin."

Mira looked a little annoyed. She had been looking forward to a night with you and not a stranger.

"Alright, I'll be right back," she says and leaves the bedroom.

[30 minutes later]

"What's taking her so long? She should be back here by now." you think to yourself.

You can wait some more or check on them.
