Sure!

"Sure!" I answered with a bit too much enthusiasm. We all knew why I was at their house but the girls danced around the fact, hiding it behind formality and hospitality.

"Let's go upstairs," Deborah smiled and took my hand. Susan and Sam trailed behind us as Deborah lead me out of the dining room to the curved stairs in the foyer.

"Are you joining us or just going to watch?" I asked Susan when we got to the door of their bedroom.

"Watch for now," she replied with a wink.

"I'm just going to sit on the sideline this time," my wife chuckled and took a seat in front of the vanity with Susan.

"Shall we get more comfortable?" Deborah asked but didn't bother waiting for my answer and she immediately started unzipping my trousers. I unbuttoned my shirt and flung it aside after my pants fell around my feet, leaving my erection uncomfortably pitching a tent with my underwear.

"Take it off!" my wife cheered and Deborah obliged by kneeling in front of me and yanked my boxer shorts down, freeing my raging rock.

"That's big," Susan gasped.

"Thanks," I smiled at her.

"Can that fit in me?" Susan wondered.

"We'll find out next week," I replied, "unless you want to find out now!"

Susan bit her lower lip as she paused to think. "Next week. Tonight is Deb's night."

Deborah stood up and grinned at me as she undid the clasp around her neck and let her charmeuse and lace gown slip off her body and pool around her feet, leaving her wearing nothing but her high heels. My erection got a bit harder while my eyes drank the beauty of her perfectly-shaped large breasts, hourglass figure, and long slender legs.

"How should we start?" the brunette asked. I was surprised that there was no hint of nervousness like she had at lunchtime, considering that we were about to have sex in front of our spouses. I guess they talked it over about her experience with me at the motel and they fully embraced why we were doing this.
