We loved our son Jonathan dearly, but having him in the house greatly complicated our sex lives. For the next few months, my wife and I had quickies with Chloe three or four nights a week. We’d make an excuse to go to the guest house or Chloe would find a reason to go in our bedroom with us. One night we went to the basement and ‘did laundry’ for an hour or so.

I got long solo sessions with my new mistress on the mornings when Rochelle was teaching, and I’d go to the museum early and give my wife a turn on her days off. Most nights we’d kneel between Chloe’s feet and quickly lick her to orgasm, then frantically make love on the floor as Chloe stood above us in her high heels, giving us orders.

Finally one Friday, the day after Lora’s 18th birthday and a month after Jonathan’s, I brought her to our house. I called my son to the living room and watched Chloe give them some instructions. “Jon, please sit on the Ottoman. Good. Lora, since you’re both too shy to ask each other on a date, we’re going to help you out. You’re here as a sitter. I want you sitting in his lap most of the weekend.”

Lora and my son blushed and stared at each other nervously. Chloe repeated, “Come on, Lora, sit on him.” As she did and Jon wrapped an arm around her, Chloe said, “You can’t kiss him that way. Turn around and spread your legs.” She stood, turned around, then straddled my son slowly. I could see a small wet spot in the crotch of her tight jeans and a growing bulge in his. Both looked terrified.

Chloe asked, “Do you like her, Jon?”

He cleared his throat and swallowed. “Um, yeah. A lot.”

“Do you like him too, Lora?”

“I… uh… yes.”

Chloe instructed, “Kiss to make sure. Taste each other’s lips.” They anxiously did. Both had reddish cheeks and huge smiles when they stopped. “Then it’s settled, you two are dating. We’ll be back Sunday. Don’t mess up the house or make any babies while we’re gone.” She handed her sister a three-pack of condoms, then followed Rochelle and I to the car.

Chloe mentioned, “You know what Jon would be doing at night if my sister lived here.
