As I laid there trying to figure out what had just happened, and whose pussy it was that I'd just eaten, and where my wife was, I heard the door open again.
"Your wife is still passed out on the couch," the unknown voice began. "This is absolutely perfect!"
I felt a fingernail trace from the base of my cock all the way up to the tip. If it had softened at all in the past few minutes, that was gone now.
"Your wife gets very uninhibited when she drinks. She told me all about how you love to eat pussy but she hates it, so I said she should loan you to me. That's when she called you and gave you those instructions--I'm pretty sure she was just messing with me and planned to play with you later tonight, but then had a couple more shots and I had to help her get home. When I got her here and she fell asleep, I thought I would see if you'd really gone through with it, and I just couldn't help myself."
"Who...what..." I sputtered.
She continued over my protestations. "And since she's still out, she's not going to remember any of this. And since you're in no position to argue..." I heard the rustling of fabric, and I felt her climb onto the bed again and once again straddle my midsection. "I'm going to take advantage of every bit of this!"
As I opened my mouth to protest, she shoved something inside my mouth. Her panties? The aroma was unmistakable...wet pussy and perfume. "Shhhhhh," she said, "we wouldn't want her to wake up!"
I felt her reach back and grab my cock, then shimmied backwards until I could feel the tip of my cock against her. She began to rub it up and down her very wet slit before sliding back in one deliciously slow motion until my cock was buried all the way to the hilt.
"I haven't had a nice hard cock in a while," she said.
