Chapter 20: Lily/ Dudley

Dudley was helping his mum load up the car after a long hot day at the beach. He was going to head to college soon and his mom, and aunt Lily, wanted to spend as much time with him as they could before he had to leave. Dudley agreed since he'd never say no to his mom and his aunt.

"Alright, I think that's it" Petunia said as he got ready to close the trunk. Dudley nodded as he wiped the sweat from his brow.

"Petunia, why is there more stuff in our car than what we originally brought from home?" Lily asked with a raised eyebrow.

"That's odd. I could have sworn we'd hadn't brought that much with us." Petunia frowned in confusion; unaware of her sister smirking behind her. All she had done was enlarge the items, she waned to be 'closer' with her nephew. Especially after seeing he carried the same thick package as his father.

"So how are we all going to fit?" Dudley asked as he looked at the packed car.

"Well, um," Petunia said as she scratched her head.

"You drive Petunia, Dudley will sit in back and I'll sit on his lap" Lily said in an innocent 'I'm-not-going-to-fuck-my-nephew-in-the-back-of-the-car-while-you-drive manner that told the two that there'd be no alternative.

Petunia just nodded since it was her car and Lily didn't know how to drive manual.

"Are you sure aunt Lily, I don't want you to be uncomfortable" Dudley said sincerely.#

"Dudley dear, you've sat on my lap plenty now I think it's time for my turn" Lily said jokingly.

The car started up and they were their way. It would take some time to get home due to the traffic and the distance from the beach to their house. Petunia kept her eyes on the road, but even if she could look back there was plenty of stuff that blocked her full vision of the backseat. Not to mention she was listening to the radio, which distracted her from the monotony of staring at the barely moving traffic. Lily sat on Dudley's lap and Dudley was looking out the window when he felt his aunt shift a bit.

"Uncomfortable aunt Lily?" he asked.

"A bit, just let me get adjusted" Lily said.

Dudley nodded and then he felt his aunt's butt rub against his crotch and felt his dick get hard. His eyes widened at this. He shouldn't be getting hard by his aunt's butt rubbing.

Crap not good, not good. Think; think, un-sexy thoughts, un-sexy thoughts. Um, Pierce streaking during that football game, um, that ugly toad looking woman that I saw at Dad's work, Miss Figg naked, Figg naked, hell, Mr Crudge naked. Stan doing a striptease, Pierce and Stan in belly dancer outfits Dudley thought rapidly.

Lily was aware what her shifting was doing to her nephew. Her eyes widen a bit upon feeling the hard organ of her nephew and licked her lips. Her core wet. She had only rubbed to see how thick he was; but now she wasn't sure she could wait to get home to sneak away with him for some 'fun'.

Back to Dudley who was fighting a losing battle with his body. He would clearly admit his aunt was still quite hot and attractive even at her age and the whole being related thing. But stating mentally to himself was one thing and doing something was another. Dudley didn't have active fantasies about his aunt ever, well, not until now it seemed. He clenched his fists as he tried to fight any urge that was bubbling up inside him.

Lily however was feeling a bit naughty as she kept up her wiggling, which slowly turned to grinding.

"Shit, Lily" Dudley muttered.

"Like that honey, like me rubbing your dick with my butt?" Lily asked with a smirk.

"Yeah, I do" Dudley murmured.

Lily took a glance to the front and saw Petunia was preoccupied with getting through traffic. She was tapping her thumbs against the steering wheel, which was a good sign to her that she wouldn't get curious on what was going on in the backseat. So, with that she stopped her wiggling, but pushed her body and butt into her nephew as she spread her legs. She dropped a hand down and unbuttoned Dudley's shorts and fished out his hard cock.

"Lily, what are you doing?" Dudley asked keeping quiet enough, so his mum won't notice.

"Having a bit of fun honey" Lily said casually as stroked her nephew's rod.

"Fuck, this is fun for you?" Dudley asked as he groaned into her ear.

"Language, I may be giving you a hand job, but I'm still you aunt" Lily chided.

Dudley blinked as his brain tried to compute this, but he could as Lily's hand kept stroking him in a steady motion. He stifled a groan as his mom gave him a hand job. This was so surreal, but good too.

"Mmm, your dick feels so hot. I like it in my hand" Lily cooed.

"Oh man" Dudley muttered as he felt his aunt's thumb swipe across his spongy mushroom head gathering a bead of pre-come.

Lily kept working keeping on task with her job. She was feeling quite excited jacking off her own nephew. And what made it more thrilling was her sister was not very far away as she did this. It made her feel like a teen who had snuck their partner up to their room for a make-out while their parents were still in the house.

"Lily, I think, I think I'm going to come" Dudley warned.

He spurted, which Lily with quick reflexes caught in a plastic cup. The cup filled with Dudley's thick wad and Lily was astounded by how full it got. She milked all she could get from Dudley before letting go. She then held up the cup for Dudley to see and flashing him a wicked smile downed it. The viscous salty liquid was so hot and she enjoyed it. She loved her nephew's come. She swallowed it and showed her nephew it was all gone.

Dudley was shocked at what his aunt had done. She not only gave him a hand job, but caught his seed in a cup and drank it down. Shit, this had to be the best fucking dream he had awake.

"How are you doing back there Lils?" Petunia asked.

"I'm fine Tuny" Lily said.

"Not thirsty at all?" Petunia asked as she waved a bottle of water for her.

"No, I had a nice drink already" Lily said showing a half-drunk bottle of water. Petunia nodded and turned back to the road.

Dudley hadn't a clue where that bottle came from since he didn't see it before. He looked at his aunt, who winked at him with that 'I'm brilliant' smile. Dudley shook his head. He sometimes forgot that his aunt was not only smoking hot, but quite intelligent too. She always had a plan and if she didn't then give her a few moments and she'd have one.

Lily wanted more, needed more. She needed her nephew's cock in her pussy, right now. So, she shimmied out of shorts revealing her plain cotton white panties. She pulled the soaked crotch aside and aimed Dudley's throbbing pole to her center and eased him inside her. She let out a moan.

"Are you alright sis?" Petunia asked.

"Uh, yes, I am. Just this is a long ride" Lily said with some controlled breathing.

"Dudley's lap too rough for ya?" Petunia joked.

"No, it fits just perfectly" Lily said biting back a moan as she felt Dudley's cock slide deeper into her pulsating pussy. "Just want to get home and wash all of our salty swimsuits and towels."

"Oh, okay" Petunia said turning his attention to the traffic.

Dudley was gritting his teeth the whole time as he felt his aunt's quim clenching around him. He couldn't believe how tight she was really. Hell, he couldn't believe his cock was inside the place his cousin had come from really.

"Nice and slow dear, I want to enjoy this" Lily whispered.

Dudley nodded as he placed his hands on his aunt's hips to help her movements. They worked in tandem as Lily slowly rode Dudley. She rocked her hips back and forth as her body went up and down. They didn't need to worry too much about being see since the windows were heavily tinted to block out the harsh UV rays. But they had to keep their movements restrained since they didn't need Ptunia to notice a thing.

Lily was controlling her breathing since she remembered her Lamaze classes. Who knew those breathing exercises would come in handy in this situation?

Dudley was breathing through his nose to compensate for not being able to really groan or moan out how he was feeling as his aunt's pussy glided up and down swallowing and re-swallowing his cock.

Lily wanted more, wanted to have her nephew's hands on her body, but couldn't since it was too risky right now. She had to keep a tiny bit of her rational mind even though what she wanted was to have her nephew fuck her, touch her all over.

"Oh god" she murmured.

Petunia didn't hear this as she got into a song that was playing. She was bobbing her head and drumming her thumbs on the steering wheel.

Dudley hissed as he felt his aunt's snatch clench around his length. Her body trembled and Dudley could feel it as his hands were still on her hips.

"Aunt Lily, did you just come?" he asked after his aunt shuddering stopped.

"Uh-huh" Lily grunted.

"Shit" Dudley said with some awe.

Lily didn't correct her nephew on his language this time. Hell, she wanted to join in. But again she needed to keep a bit of a level head.

The copulating went on as Lily bounced up and down on her nephew's lap and Dudley gripped Lily's hips assisting her as much as possible.

"Lily, coming" Dudley alerted.

Lily quickened her pace and with a final push down, forcing as much as her nephew into her quim as possible as Dudley released his seed deep inside her. Lily shuddered again as another orgasm rocketed through her body from just her nephew injecting his seed into her. Both groaned at this. They stayed like that, just feeling the euphoric feeling draped over them.

When it passed Lily got up off Dudley and put her panties back on along with her shorts. Just as she got herself fixed up to look like she hadn't had sex the traffic got really moving.

"We'll be home in no time now" Petunia declared.

"That's good Tuny" Lily said.

"Yeah, great mum" Dudley chipped in.

Lily smirked as she looked a head. 'I've fucked your husband and now your son, Tuny. And I an't giving them up.'…
