Got the full thing, here's how I did it, not sure what options are flexible, and I am not including single option decisions:
Now is not the time.
Speed up, fucking her harder.
Keep going, but slow down and delay your orgasm.
This is perfect, just the right speed... keep going.
Speed up; you can feel how much she wants it.
Stop... it's time for that thing she loves.
"You will cook and serve dinner naked tomorrow."
You gently tease her legs apart to continue fucking her.
"Nothing important. Now, we both have big days tomorrow."
... wait. You hear familiar noises from the shower.
See what you can find on the Internet.
... head off to work.
Yeah, kinda still pissed. What's up?
The guy you left me for?
So, why get in touch now?
Let me think about it.
... get to work; it's better to talk with Allison about this in person.
... other activities. The situation with Annie can wait.
... cuddle up to Allison for the night.
I still can't believe you're asking after what you did.
I'm listening.
And what kind of apology did you have in mind?
It's going to take more than make-up sex.
I'm not trying to hurt you.
Isn't there someone else who could help?
I don't want to risk my relationship.
We haven't talked about it.
I'm not sure how'd she react to us having sex.
If I'm going to risk it, I need an explicit commitment.
Really?
... text your "friend".
It's been a while since we've...
That, and Annie.
"Wanted to remind them I work here. What are you up to?"
"She's doing great! How's... I'm sorry, I've forgotten his name."
"What happened?"
"We should grab coffee sometime. Away from work."
"Of course! I think you two would get along great."
... Annie's offer.
"I don't know. But it's very appealing."
"It would be complicated, but worth it."
"Allison might be ready to hear about it."
"She's been very sexual, in new ways."
"'My girlfriend is a nymphomaniac' doesn't earn much sympathy, I know."
"Yes! How did you know?"
"Perhaps hypnosis explains Renée's new breasts."
... go down on her.
... start fingering her.
... ask her to go down on you.
... help her up, and head to dinner.
... impulsively present her with the voucher.
"Excuse me for a moment." You duck to the bathroom.
... follow Renée into the kitchen, having taken the ring.
"Yeah. Just for the weekend, I hope."
"No point in being mad at her forever."
"I hypnotized her to accept it."
... return to the subject of Renée's boobs.
... turn to point her out to Allison.
"As long as you are OK with me and Renée."
"She offered me a blowjob, and I accepted."
"Next time, I'll order you to join us."
You ask, "Then, how about a roadside blowjob?"
Excuse yourself to the bathroom.
"I have something I want to do to you."
"Let's talk about you being more adventurous."
"You want to do adult modeling."
"We're going to fuck now."
... say, "I want to come on your tits."
This should get you there, now, obviously its tailored to my tastes, so experiment around, see what works that fits yours better.
