Why not?

I couldn't help myself. My mind felt a magnetic draw to her, and I had to give her another feel. This time I slid the knife edge of my hand in between her legs, and rubbed up against the damp crotch of her shorts. This time she didn't flinch, but looked back at me and smiled knowingly. What happened next startled me more than I can say.

"Megan" Amanda began. "Is it all right with you that your husband is groping me from behind?"

Megan stopped and turned around. "He's a horn dog, Amanda. If you don't mind sharing yourself with him and me, we can make that part of your duties as well. Are you okay with fucking him as well as me?"

Amanda turned to face me, and smiled sweetly. "I don't know. I'll have to check out his cock first. Would you tell him to drop his pants please?"

Megan giggled. "Oh, he's adequate down there." She was enjoying this turn of events, as well as my embarrassment at having been caught groping the yet to be hired help. "You heard Amanda's request. Drop your pants." She now stood on the stairs beside Amanda, looking on. "Show us that beautiful cock of yours that knocked me up."

Red faced with embarrassment, I undid my belt and unzipped my jeans, allowing them to fall to my ankles. I was about to yank down my boxers when Megan signaled me not to. "Amanda, go ahead and finish unwrapping your Christmas gift" she chuckled.

Amanda sat down on the stairs, and gazed up into my eyes with a mischievous smile. She hooked her thumbs in the waistband of my boxers, and slowly pulled them down. Time seemed to stand still, and everything went in slow motion. I was being manhandled by the new Nanny and my beautiful wife. Had they planned this all along? Had Megan known how I would react to Amanda? She worked my boxers down, and out flopped my semi-hard, pulsing cock. Amanda looked at it with appreciation and admiration. "That is a nice size!" she exclaimed. She gently touched the head with her fingertips, causing it to jump, and become stiff. She flinched in surprise as she lilted happily. "I'm very impressed!"

Megan laughed. "Oh, he'll give you the ride of your life!" She sat down on the stairs beside Amanda. "No birth control, Amanda" she said, taking hold of Amanda's free hand. "I want two children, but I also want to get back to my career. That's where you come in. You'll be the live in nanny, and surrogate mother of our second child. I also need you to become a wet nurse. My babies have to eat, you know. But don't worry, all of your needs will be taken care of, and money isn't an object. We're going to spoil and pamper you. Do you accept these conditions?"

Meanwhile my cock was aching, and ready to explode as it twitched wildly. Amanda said nothing for a moment, then turned her attention to Megan. "You don't mind if I taste him first before giving you an answer, do you?"

"Only if you're willing to share it with me" Megan responded. "That's why I sat down beside you." She turned Amanda's head, and closed in on her full, pouting lips.
