Volunteer to show her the closing procedure

Not having anything better to do, you decide to stick around and get a workout in at the gym. By the time you've finished, then showered it's about an hour away from closing and devise a way to spend a little more time with Tiffany. Approaching the closer, Bill, you volunteer to stick around to teach Tiffany the closing procedure so that he can take off early and enjoy the rest of his weekend. Telling you "that's great" and that he's "got a party to get to anyway" he thanks you and leaves.

Tiffany arrives shortly after, surprised to see you sitting at the front desk again. "David, I thought I was supposed to be closing with Bill?" she asks you.

"Yeah, you were," you reply. "but he had a party to go to and asked if I wouldn't mind covering for him." you say, twisting the truth a little.

"Well, I can't say I mind." she says, moving into your personal space and placing her hand on your chest. "I definitely could have been stuck with someone worse training me today. Hopefully I'll get a chance to work with you a lot more after today, too."

"I can't say I'd be upset if that happened." you respond. "But I might not get all my work done, being distracted staring at that body of yours all day and thinking about all the things I'd love to do to it."

"Mmmm, yours is pretty nice too." she says reaching down and giving your ass a quick squeeze. "I'd love to find out what you'd do to me if you got the chance."

You give her a half-assed review of the closing procedure; showing her the shutdown of the computers, cleaning of equipment, where to bring any receipts of payment...etc. while the two of you spend more time swapping thinly veiled sexual comments than anything else. After the last of the clients and staff leave you show her all the doors that need to be locked and start walking towards the staff exit. "You know," you say nonchalantly, "one of these days I should give you a sample massage. With you working with all the clients as much as you're going to, it couldn't hurt to have you recommending me to them. Maybe we could work out an under the table finder's fee for you if that's something you'd be interested in doing." you suggest.

Placing her hand on your arm to stop you, she says smiling at you "Why not right now? Unless you've got somewhere else to be or you think we'd get in trouble for staying here later."

Well, you've reached the point of no return. Flirting is one thing, but this has the chance to go beyond that very quickly. Should you head back towards the massage rooms and make good on your proposition or beg off until another time, making an excuse?
