Not now

Robin looks at the examination table and shakes her head. "I see patients here. How about this? My husband's flew out to Tokyo today for business, so why don't we get dinner and see how it goes?"

You agree and Robin takes off her coat and grabs her purse. As you walk out together, Robin says, "Did Tina already leave? She's usually the last one out. It's fine, I'll lock up."

Holding her hand, you and Robin stroll around for a while once outside until you find a small Italian restaurant. It's pretty empty inside and you're seated immediately. The food isn't great, but you hardly notice as you chat with Robin and get to know each other. By the time the check arrives, the two of you are laughing like long acquaintances and exchanging stories about your travels and families. Robin comes from a big family with 2 sisters and 3 brothers and she enjoys listening about your parents' business.

It's only around 7pm when the waiter returns with your credit card and you hold Robin's left hand on the table. You can feel her wedding ring poking against your palm. "My place?" you ask hopefully, and she nods shyly.

You hadn't found an opportunity to tell her about the magic rings so the two of you hail a cab off the street to the mansion. She had noticed the rings on your hand, but said nothing, and you didn't want to break the news too quickly. You'd find an appropriate time to do so later, you thought to yourself.

Once you're in the door, your hands are on each other as you two hurry up to your room and undress each other on the way. Luckily the house is empty and you have it all to yourself. A mostly naked Robin who's only wearing her bra is still laying below you and unbuttoning the last 2 buttons on your shirt when you penetrate her. Somehow, her pussy feels even better than it did hours ago when you had fucked her at the party. The two of you go at it like teenagers having sex for the first time, and it doesn't take long for either of you to cum. You roll over panting while Robin massages your cock and with her small hands to get you aroused again. You're happy to just lie there and close your eyes, dozing off after a while.

You wake up when the door bell suddenly rings.
