DISCLAIMER: I do not own any of the characters in the following story. They are from the movie Grown Ups/Grown Ups 2 and thus belong to the owners of the franchise.

This is a work of pure fiction and is centred around Greg and his Mum, Roxanne. This is the chapter where the story line will splinter away from the movie and the smut begins in proper.

WARNING: This fanfiction will contain a level of smut between two family members. If this is not for you, don't continue to read. If it is, enjoy.

Roxanne's POV:

I watched transfixed as my son walked down the steps into the garden wearing nothing but a pink shirt that just covered his underwear. Why he had decided to not wear trousers I did not know, but I wasn't going to complain if it meant I got to see a bulge in his pants.

The party began, and Greg seemed to be avoiding me and spending a lot of time with Andre and a girl from school. Disappointed at the looks the pair of them were sharing with each other, I turned my attention to my husband and our friends, just as a bunch of college students appeared over the hill at the top of the garden. Yelling loudly, they descended towards us and, with a battle cry of our own, we launched ourselves straight back at them.

Greg's POV:

Cursing, I looked up at the top of the garden, where a gang of college students was charging down the hill, as everyone at the party began to engage in a brawl. My eyes quickly found my mum, fighting one of the students, her breasts bobbing up and down as she did so. Completely transfixed by this, I totally missed the arrival of the college student in front of me, until he yelled loudly and called me a slur relating to my mother being of Latin descent. Glaring at him, I planted my foot firmly between his legs. Yelping in pain, he doubled over, but one of the girls I'd been hanging out with at the lake earlier returned the favour, leaving me equally crippled. Out of nowhere, my mum appeared and kicked the girl out of the way before asking me if I was ok. Nodding limply, I watched as the last of the college group was rounded up and kicked off the lawn, before weakly apologizing to my mum and hobbling inside to deal with both the pain of the kick I had received, but also before she saw my growing arousal.

Roxanne POV:

Having just seen off the last of the college kids, I left my husband at the party and headed inside to check on Greg, who had run inside, presumably due to the fact he was kicked in the crotch. Whilst I was genuinely concerned about my son, I also had a naughty plan forming in my mind that started with a nice caring conversation and ended with me being bent over and pounded hard by his cock. Having now reached his bedroom, I stopped in front of the closed door and knocked lightly.

'Greg honey, are you in there? Can I come in please?'

Suddenly, I heard the bathroom door open and then close again behind me. Spinning around, I saw my son standing by the door, clearly having just emerged from the bathroom.

Moving towards me, he grinned slightly before answering, 'As you can see Mum, I'm not in my bedroom. But', he said, striding past me and opening the door to his room, 'you can certainly come in if you want to talk.'

Pausing only to swat him around the head for his cheeky, smartassed answer, I strode past him and sat down on the end of his bed and, closing the door behind him, Greg came and perched beside me. Turning to face him, I looked him dead in the eyes, like I always do when I want him to know I have something serious to say.

'What?', he asked, spinning slightly so he could view my face better.

'I want you to know that I heard what that college boy called you and that I am here if you want to talk about it. I also came to check that you weren't in too much pain.'

'Thanks Mum. I wasn't too bothered about what he said to me. More angry that he'd say it about you to be honest. That's why I kicked him I guess.'

Deciding it was time for Phase 2 of my plan, I wrapped my arm around his shoulders and pulled him closer, at the same time pushing my chest forward to help accentuate my breasts.

'That's so sweet of you Greg, defending me like that. Thankyou. Now, tell me if you're in any pain at all.'

'I was, but I'm better now' he murmured absently, shifting slightly in an effort to hide the growing bulge in his pants.

Bingo, I thought, Phase 3 can now be actioned. 'Looks like they didn't fulfil their intention very well,' I said, pointing out his now very tented crotch and smiling lightly.

'Sorry', Greg said, trying to hide it unsuccessfully.

'It's alright,' I said, 'I've always had that effect on men and I was beginning to worry I was starting to lose it, what with age and that.'

'Don't worry Mum, as far as I'm concerned, you've never lost it. You are one hot lady,' my son replied, before closing his mouth and wincing, as though realising what he'd just admitted.

I grinned, knowing that I'd got him, before leaning in and whispering, 'And you have grown into a hunk of a man who any women would love to rip the pants off of. Hell, if I wasn't your mother, I'd have done it long before now.'

'Don't let that stop you,' my son said cockily, resting backwards on his elbows, no longer trying to hide his straining erection. Slightly startled by his direct answer, I also back off and looked at him in surprise, only to see lust written all over his face, a feeling quite clearly reflected in my own. Without a second thought for consequence, I launched myself at him and we began to kiss strongly.

The smut has started! Next Chapter will be the steamy one. Brace yourselves, both Roxanne and Greg are going to be powerhouses in bed, so it won't be a light gentle night of sex.

Reviews are welcome, I'd love to know what you think so far and if you've got any suggestions don't hesitate to let me know and I'll do my best to incorporate them into my writing. :)
