Neither realizes

The pair continued to fuck, neither realizing that their partner was not their spouse, until both succumbed to blissful exhaustion, and fell asleep.

When Brian awoke, his head was under the covers, pressed into a pair of boobs, as his morning wood rubbed gently against her smooth leg.

He started to move, but the woman's hands pushed him back down. He almost said something, but his mouth was covered by one of the hands. "Shh!" she hissed.

"Did you say something, Dear?" Mr. Goodman asked.

"No, I think it was the radiator." Jessie replied.

"Alright then, hurry up and get dressed, I'll meet you downstairs."

The door to the room opened, and then closed, and he heard footsteps travel down the hall, and then the stairs. The blanket was pulled off his head, and as his eyes adjusted, he saw his brand new, beautiful next door neighbor, Jessie Goodman.

He swallowed. "Oh my god. We didn't."

She looked away, "We did."

"I'm married."

"So am I. I thought you were Nick."

"I thought you were Phoebe."

"I just woke up and... you were there... naked." She remembered staring at his dick, knowing that it had been the tool giving her so much pleasure in the night, right next to her husband, and wishing it didn't have to be forbidden.

"You hid me?"

"Please, we can't tell anyone!"

"You're... you're right." He tried not to think about her naked body lying in front of him as he spoke, what her chest felt like, her legs... and the pleasure of the sex. He had seen many beautiful women, but after he married Phoebe, he always viewed them with detachment. They were pretty, but he didn't need to think about it, he didn't stare at their breasts, envision kissing them. But now, with Jessie? His erection wasn't going away any time soon.
