You follow her to the garage and to the new car she's bought you.

"Oh my God mom, you bought me a car?!" you said, completely blown away as you stood there in the garage staring at a sweet looking dark green Chevrolet Cavalier that was parked next to your mother's BMW.

"Well I can't exactly have you taking the bus over here now that you're officially a man can I?" she giggled, grinning with delight at your reaction, as she then placed the keys into your hand.

It took you a second or two to actually respond, never having imagined that you would actually receive a gift like this (especially on top of what you'd already been given), nor really knowing what to say now that you had. "Wow! I mean...are you sure? This is totally awesome and everything, but are you sure it's not too much?"

Brushing this suggestion off, your mother replied, "No, of course not. You're dad might not be too thrilled about it and your brother and sister might be a little jealous, but as I said, you're 18 now and you really do need a car of your own. And seeing as I am your mother and I am making quite a bit of money now, I'm allowed to spoil you from time to time. It's a mother's prerogative."

Laughing a little as she said this, you immediately launched yourself at her, hugging her as tightly as you could (or at least as tightly as her huge breasts would allow)."Thanks, mom! This is totally the best present ever! I can't wait to see Randall's face when I pull up to school in this bad boy!"

"Yes, well, just be careful with it," she said as you broke again from the hug, in a slightly more motherly tone, "Just because you're 18 now and you've got your own car, it doesn't give you a license to go wild all of a sudden."

"No, I won't. I promise. I'll take real good care of it."

Smiling at this as you both turned again towards your new car, placing an arm around your waist as she did, she responded, "I know you will, sweetheart. You really are the most responsible one in our family...and that's including me!" before ushering you forward to properly explore your present. "Now go on, you'd better take a look inside. See if it's 'up to scratch' or not."

And that you did, inspecting every inch of your new wheels - which while in no way matching the epicness of your mom's BMW still seemed like a pretty sweet ride for your first ever car (being way cooler than a lot of what your friends drove). After about twenty minutes or so of this, while your mom waited patiently at the side, you eventually decided to leave the test drive till later and the two of you returned again to the kitchen so that the birthday lunch could commence, still giggling with excited glee as you did.

The rest of the afternoon progressed almost as well as it had begun, as the two of you sat down at the dining table, enjoying the delicious meal your mother had prepared and chatting casually away again, just like you used to. Although the fact that you were sitting opposite one of the most famous and hottest porn stars in the world wasn't lost on you, and your eyes were continually checking her out through the entirety of lunch, you found that you were a lot more relaxed around her now than you had previously been and you did your best to remain that way - not wanting to ruin this special day by acting weird and ruining things. Your mom seemed on good form also, clearly enjoying sharing this special day with you, and although she still made a conscious effort not to bring up her career as 'Amber Knights' or the various guys you knew she was now fucking on camera, she did talk at length about nights out with 'some of the girls' and other activities that you felt slightly jealous you couldn't be part of. You didn't let this bring your mood down however, feeling a whole lot happier and more content now than you had in a long time - finding your mother's presence to be absolutely intoxicating and soothing, almost like a **** or something that you desperately needed to be around.

After finishing up lunch (being pretty damn stuffed), you headed to the bathroom while your mom cleared up the dishes, having decided next to watch a DVD. After doing your business though you couldn't help from quickly rubbing one off, picturing as you did your mother giving you an alternative birthday gift - her naked body wrapped in nothing but a bright red bow, as she lay on the kitchen table waiting for you to fuck her. It was the kind of fantasy you had often, and although you did feel slightly guilty and ashamed afterwards (what with her being just a couple of rooms away) you really couldn't help yourself, finding everything your mom did now - whether it be jamming a giant dildo up her pussy while sucking on her huge naked tits, or simply flashing you one of her beautiful smiles - to be arousing beyond belief.

Heading back out of the bathroom once you'd finished up, you stopped in the hallway for a moment and glanced round at the door where you knew she now kept all of her porno paraphernalia, wondering to yourself whether or not you should take this opportunity to have another quick peek inside. You'd seen what was in their before of course, but that had just been a fleeting glance, and back then you had no idea your mom had become a porn star. Now though, you knew for a fact she dressed up in those ridiculously slutty, sexy clothes inside and performed all manner of lewd and perverted acts for horny guys just like you, and that knowledge made the thought of actually doing it all the more seductive.

On the other hand, last time your mom had caught you sneaking about she had been incredibly disappointed in you and you had felt absolutely awful for doing it. Though that was before you'd not only joined her website and started communicating in secret with her, but also started jerking off to every single picture and video she released every night - treating your mother (even though she was performing as 'Amber Knights') as your own personal sex idol. Surely this couldn't be any worse than that?

Deciding that it couldn't, you quickly and silently turned the handle and went inside, figuring you had a couple of minutes at least while your mom was busy with the dishes. Inside it was just as you remembered it (though a few things did seem like they'd been shifted and there wasn't so much clutter on the floor) with racks of clothes, posters, DVDs and just about everything in between filling the room. Heading first over to the myriad of clothes, feeling your arousal quickly growing again as you looked at them, the first thing that caught your eye was (apart from a number of ridiculously tight and revealing latex numbers) a hanger containing several bra and panties sets. While you usually would have assumed that underwear and stuff would be kept in drawers rather than on hangers, it was obvious from looking at these that there would be barely be any room - the giant, beautifully detailed bras being positively ginormous in comparison to regular ones.

"Wow, her boobs were actually inside these..." you said to yourself as you rubbed at your crotch, reaching out to feel the soft, silky material of the mini-parachute like bra. Thumbing through the various different colors and styles, still amazed by the huge proportions (seeing it on screen was one thing, seeing it in real life was something else), your fingers then stopped when you came across a very familiar looking lacy blue set - it being the one she'd worn for her first ever photo shoot. "No way!" you grinned, pulling it immediately from the rack and holding it up for your inspection, laughing to yourself as you realized you could fit your entire head into a single cup. Admiring every inch of the material, getting great pleasure from touching the very bra your mother had been wearing moments before she'd stuffed a huge purple dildo up her pussy (figuring that it had to be custom made due to it's size), your attention then shifted to the panties below, where that very same pussy had been snugly nestled inside...
