I slinked out of my 34 year old sister's room. The short walk down the dark hall to my room was one of the longest.
I opened the door with my keycard, which beeped this time.
My erection was still obvious as I walked into our dark room.
My wife lay naked on our bed, with a sheet meticulously arranged over her gorgeous curves. Her breasts were pushed together as she lay, showing me the cleavage and her right nipple and areola. Such sights were the dreams of every pubescent male.
Ten minutes ago, I would have indulged her body in all sorts of oral pleasures, but now I had some explaining to do.
"Babe, wake up."
She rolled onto her back, sheet falling to expose her gorgeous rack.
"I need to talk with you." I continued.
"I can't, honey; I've got a headache." Her games from this evening continued.
I took a deep breath. "Babe, I just accidentally fucked my sister."
The silence that escorted my wife from snoozy/horny to awake and furious was far too long. I'd have preferred the executioner's sword to swing faster and truer.
She stirred. "What the fuck?"
I continued. "It's true. I went into the wrong room. It was dark, and she had a pillow over her face. I thought she was you. She thought I was her husband."
Now wide awake, my wife sat up. Her sleeping mask was cast aside like the wrapping on an impatient child's present.
"And no one thought to check they had the right person on the end of this fuck? I mean, she's 34 and you're 36!"
"I assumed it was part of our game, the darkness and pillow. I didn't speak to her."
My wife dropped her arms by her side. I took note of how her arms perfectly captured her breasts as they were slightly pressed together in their natural state.
"Did you cum in her?"
"Yes."
"Fucking hell! Stand up."
Not in the position to argue, I stood up. I'd pulled on my pants as I scurried away but still had no shirt on. My cock continued to betray me by being semi-hard.
My wife continued. "Get naked."
I slid off my pants and stood in front of her.
"Oh fuck. You did fuck her, didn't you? I can still see her juices on you."
"I'm not lying to you."
Her look softened as she realized that at least I was being honest with her.
"Did you eat her pussy?"
"Yes."
"How did you do it?"
"Exactly like I eat you out. I thought she was you."
"Did she like it?"
"Yes."
"How much?"
"About as much as you do."
"So, she loved it then." I didn't respond. Yes, she had loved my tongue inside her.
"What are her breasts like?"
"They're...good."
