Not at first

Amy stripped down and we had sex on the floor of her office. We did it missionary style, but Amy rubbed my nipples and talked to me the whole time -- both things she knew I loved from our earlier talks.

"Cum in my pussy," she said. "Someday we'll have another slut waiting here to suck it out of me. Won't you like that? Or maybe you'd like to shove my face into her pussy and make me suck her off?"

I came quickly.

"I don't know how long this will take to work," Amy said. "Hopefully not the full length of your marriage... that would be a pain. But I suspect there's some other trigger."

Amy and I had sex a couple of times a week for the next month, mostly in her office, but sometimes at my apartment and once at her house. We mostly stuck to vaginal intercourse, but we tried different positions -- missionary, doggy-style, cowgirl. I loved playing with her long, curly hair, sometimes gently pulling it while fucking her from behind. I dreamed of pulling it roughly but I didn't dare. Twice Amy gave me long, luxurious blowjobs. Amy wasn't as good at this as Jane was, but she didn't hesitate to swallow.

After one fuck session in her office she said, "I don't know why this isn't working. Don't get me wrong, the sex is fine, but I haven't felt any compulsions. Maybe my whole theory about this is wrong."

"I don't know," I said. "It does seem like a stretch."

"Let's try again Tuesday," she said.

"I can't," I replied. "I have a business trip and I won't be back for two weeks."
