A (mostly) uneventful evening

As Kelsi heads into the restroom, you wait for your erection to go down before heading downstairs to greet Derek and Lisa. You feel horrible the entire time for how you had just been perving over their daughter, and you find yourself hoping that she doesn't narc you out.

When your cock returns to normal, you make your way down to say hi. It has been several years since you've seen each other, but you had Derek had been best friends since kindergarten. You picked right up where you'd left off, and soon the two of you, along with Lisa, were sitting on the patio, sipping a beer and talking just like old times.

Lisa was hot, and while you may have jerked off to her a few times, now she was more like one of the guys. She was skinny with a thick ass, and unlike her daughter, she was about as confident as they come.

She had come along while you and Derek were in college. You actually met her first, at a frat party. You brought her back to your dorm and spent the rest of the night 69ing each other to multiple orgasms each before finally passing out. While it had been an amazing night, the next day you had both quickly began to realize you weren't really a match. Hanging out with her was fun, but it was like hanging out with your sister.

That afternoon Derek had come back to campus and the sparks between them were undeniable. From that day on they were a couple, and the three of you never discussed the night you and Lisa had spent together. You'd never told Kelly, but you had no idea of Lisa had ever told Derek. It was just never an issue.

After a while Lisa left to prepare supper, while you and Derek discussed houses in the area that were on the market.

When she called you in for supper, Derek excused himself to go cleanup and Lisa went into the dinning room to set the table, leaving you alone in the kitchen with Kelsi. She was bent over getting something of a lower cabinet. She had traded the bikini for a conservative pair of khaki pants and a baggy polo shirt. From the angle you were standing, you had an amazing view of her clearly visible panty line. You couldn't help but stare.

She stood up holding a plastic bowl, catching you looking. She blushed and quickly looked down at the floor.

"Hi, Uncle Jason," she said sheepishly. You were pretty sure she glanced up at your crotch.

"Sorry sweety, didn't mean to scare you," you replied.

"You didn't scare me, I knew you were here," she said with a smile.

Fuck, you thought, did that mean she had stayed bent over that way on purpose? Or did that mean she was too nervous to get up because her pervy uncle was checking out her ass.

"Did you have fun hanging out with my parents?"

"Uh...yeah, it was just like old times," you told her.

"Good, I think they've missed you and Aunt Kelly," she said. She figited with the bowl and nervously but her lip. "I know I've missed you. Maybe we can hangout and catch up while you're in."

"That would be fun," you said.

Kelsi smiled in clear relief, then say the bowl down and suddenly hugged you. A bit surprised by the sudden embrace, you accidently found yourself grabbing her ass as you tried to hug her. She looked up into your face with a smile and then blushed. She then lay her head on your shoulder and hugged you tighter. Not want to make things any more awkward, you held her that way, cupping her young ass in your hand.

You heard the sound of someone approaching, and quickly separated. A few minutes later you all sat down to supper, which went by with no secret footjobs under the table and nobody getting naked. Lisa took a few dirty shots at Kelsi for "needing to find a man" and make grandbabies. You felt sorry for the younger girl, who just stared at her mashed potatoes.

After supper you all helped clean up. You got a few good looks at both Kelsi and her mother's asses but neither seems intentional. Then you and Derek sat down on the living room to BS for an hour or so while the girls went their their separate ways.

Eventually Lisa appeared wearing a sheer nightgown. You could see the faint hint of nipples through it, but she didn't seem to notice.

"Derek, we both have to be up early tomorrow for work, so you don't need to stay up all night," she said.

"She's right," he said after a brief pause. "You know how it goes."

"Make yourself at home, Jason," Lisa said with a polite smile. "Our house is yours as long as you're here. You know where the kitchen is. There's plenty of food and beer, have all of either that you want."

Derek tossed you the television remote and they both bid you good night. You got one quick glance at Lisa's gown riding up her ass, which was enough to tell that she wasn't wearing any panties, and then they vanished upstairs.

You debated going on to bed yourself, but clicked the power button on the television instead. The television logo was still on the screen when Kelsi suddenly appeared at the end of the couch, dressed in a matching shirts and tank top pajama set covered with images of cartoon kittens. The PJs were clearly much too small for her. The shirt showed off most of her flat stomach and clung much too tightly to her breasts, clearly revealing her nipples. One of the kittens on the shorts looked to be in danger of falling into her clearly visible camel toe.

"Hi Uncle Jason," she said. Despite the revealing and inappropriate outfit, she stood very awkwardly and several times attempted to pull the tight fabric away from her nipples and crotch. "I wanted to see if you remembered these pajamas. You bought them for me when we all went to the beach."

It seemed that you vaguely remembered Kelly buying Kelsi a pair of pajamas when you had all gone to Panama City Beach on vacation one year. Kesli, who couldn't have been more than ten or eleven, had spent the night with the two of you so her parents could have a date night. You remember popcorn and some random Disney cartoon.

"You've certainly grown since then," you said.

"Do they make me look fat? I'll go change."

"No, it's okay," you told her. "You look beautiful."

She in fact looked hot as hell, which made you feel like a dirty old man. You did kinda want her to go change, but not because she looked fat. You were already getting a chubby just looking at her.

"You mind if I hangout with you?" she asked. "It's Tuesday, which is mom and dad's sex night. I don't think they realize that sound carries through the vents, and I don't want to sit on my room alone listening to that."

That explains the sheer nightgown, you thought. It might also explain why their daughter was awkward. You couldn't imagine growing up having to listen to your parents fucking.

"We can watch a movie, play a game, talk or whatever you want, just don't make me go to my room alone and listen to them doing it."
