Sam knocked.

We did not get to snuggle for too long because there was a knock on the bedroom door.

"Can I come in?" Sam asked through the door.

"Give me a second, sweetie," Emma shouted, covering herself with the blanket for modesty. I could not help but chuckle at the thought that even though Sam and her had seen each other naked many times during our swinging days, Emma still felt the need to cover up.

"Come in, honey," I yelled.

Sam opened the unlocked bedroom door and squealed when she saw Emma lying next to me, while I sat up with my limp dick resting on my thigh. "You should keep your butt up so you won't leak!" My wife grabbed a throw pillow and flung aside the blanket, much to Emma's embarrassment, to tuck it under her friend's bum to raise it. Not caring that Emma and I were naked, Sam sat down on the bed next to her friend and beamed an excited grin. "How was it?"

Emma looked at me before smiling at Sam. "It was amazing!"

"I could tell from your moaning!" Sam giggled and kissed her friend on the forehead. "Hopefully you got pregnant tonight!"

"Well, we should keep trying until Emma ovulates this Friday," I interjected.

Sam and Emma both glanced down at my cock that stirred awake at my suggestion and laughed.

"Of course, honey!" my wife giggled. "We want to increase her chances as much as possible!"

"So that means you should cum in me more than once each night," Emma added with a wink.

I guess I was not too subtle being a horndog.

"Besides, Bill still has to fulfill his side of the arrangement," Sam grinned at me.

"Maybe tomorrow night," Emma proposed as she pushed herself up. "Anyway, I should go. I have to work tomorrow." She kissed and hugged Sam before turning to me to whisper in my ear, "Thank you for the amazing fuck."

I grabbed a robe before Sam and I walked Emma to the front door to see her off. My wife squeezed my butt while she watched her friend drive off.

"Do you have enough energy to make sure I'm pregnant, honey?" Sam asked while I locked the door.

"I'll down some Red Bull if I need to!" I responded, scooping her up in my arms to carry her back to our bedroom.
