Chapter 3

After work, Molly went straight to the bedroom and brought herself off.

The subway ride home had been an interesting one; she'd felt like every man on the train was staring at her, as if they all knew exactly what she'd done, what a naughty girl she was. It had fuelled her fantasies (even as she knew it was all in her head) and by the time she got home, she'd reached a peak level of excitement.

Laying on her bed, Molly remembered the look on Luke's face as she'd disrobed (she had been careful to only slip out of the top of her dress. She didn't want Luke to see her tattoo and start thinking she was unprofessional.) and the look of excitement as he realised that his fantasies were coming true, that the sex goddess in front of him was going to let him titty-fuck her, let him come all over her face.

All over her face ... Molly sat up abruptly, and one hand shot to her face in realisation. That's why she'd had so much attention on the way home - immediately after his orgasm, Luke had gotten flustered and before Molly could make a move, he'd practically run out of the office. She'd been left alone in her office, face covered in cum. Thoroughly dissatisfied, she'd redressed and left without stopping to look at herself in a mirror, without cleaning herself up...

No wonder she'd received so many stares on the subway.

For some reason, the knowledge that everyone on her train knew what a slut she was stoked Molly's passion, and she continued playing with herself, imagining all the men from her train going home and doing the same. She pictured all the men from work playing with themselves while thinking about her breasts, her cleavage, imagining lifting up her skirt and plunging their hard cocks deep within her pussy, grabbing her boobs and fucking her ass...

Molly arched her back as she came, images of strangers and friends taking her from behind filling her mind. She lay on her bed panting, her mind blissfully blank, and it was several minutes later that she realised what she'd been thinking about.

That was new. She'd never had such a strong fantasy play out in her head, and she'd certainly never had any desire to try anal sex before. A few of her boyfriends had asked, but a combination of self-consciousness about the size of her butt and general ickiness about the idea had caused her to say no.

But as she'd played with herself, she knew what it was that had really pushed her over the edge. The idea of letting someone enter her back door was suddenly strangely exciting. Perhaps this Saturday, she'd let John ... but of course, that meant (even more than other positions) that he would see her tattoo, which she was sure he wouldn't appreciate the same way she did.

Molly removed her clothes, and walked over to her full-length mirror to admire her tattoo once more. It was really starting to grow on her. She hadn't been sure if she liked it at first, but the longer she looked at it, the more she appreciated the artistry - the smooth, neat lines, the vibrant colours ... she was almost disappointed that it was the sort of thing that she had to keep secret. If John saw it, he'd be furious and confused, and showing it off at work would kill any chance she had at being taken seriously around the office ... it was a real pity.

She was about to change into her gym clothes and head off for a work-out when she noticed something else in the mirror. Her ass had ... it seemed to have grown, somehow. It was fuller, rounder. She turned to the side, and could see it jutting out, as if a perfect semicircle had started to form at the top of her legs.

The change must have been the result of her new work-out routine, Molly realised, (the new routine being, of course, working out at all) but she was amazed that it was paying off so quickly. She stroked it, enjoying the feel, the firmness. Her ass was a third bigger than it had been a week ago, and it felt sensational to the touch.

Molly stared at the mirror for a few more minutes, checking herself out, before she shook her head, cleaned herself off and left for the gym. Tonight, at least, the guys would have a slightly better view to stare at.

The weekend came all too quickly for Molly. The rest of her work week had followed the same pattern as Monday and Tuesday - each day, she'd gone into work, wearing more and more outrageous outfits. There hadn't been any objections - the closest she'd come was on Friday, when her boss had asked her into his office, but before he could properly start she'd distracted him.

"What do you think of this dress?" she'd asked, and done a little twirl to show it off. The dress was so short that a twirl was all that was needed to display her panties (and her new, magnificent ass) and Molly's boss had been tongue-tied for the rest of their meeting.

Her nodding probably hadn't helped - every time her boss said anything, she'd agreed vigorously, causing her breasts to noticeably jiggle. At first she'd just been showing how much she agreed with everything her boss said (he'd been so right about everything lately) - the jiggling side-effects were just an added bonus.

She hadn't worn a bra all week - on Wednesday, her dress had been much less low-cut than the one she'd worn the day before ("and if I got away with that dress without a bra..." she'd reasoned) but Molly was starting to realise that she just didn't need one.

Luke had started staying late at work with her every night. At first she'd felt guilty, like she was cheating on John, but she'd soon realised that she wasn't technically cheating. She never had sex with him - he never even saw her naked below the waist. It wasn't cheating, it was just two attractive young people enjoying her boobs. And after all, who has the rights to stop a woman enjoying her own boobs, and inviting a friend to do the same?

She wasn't a slut, she told herself, even as she unknowingly mouthed the word to herself. Slut. Slut. Big butt slut.

She was having no trouble sticking to her workout program, and it was yielding amazing results. All she did was run on the treadmill for a few hours each night, but so far it had caused her to lose weight, feel full of energy all the time, increase her sex drive, and (somehow) double the size of her ass. If Molly had tried to wear a bra, she would have noticed that her breasts had been growing as well - she'd already spotted that they were perkier and bouncier than they'd ever been before, and sat on her chest proudly, without needing support of any kind.

Of course, some of the changes that her workout had provided were a bit inconvenient. Her new-found energy meant that whenever she wasn't at work or working out, she just bounced around her apartment, restless and uneasy. She'd found that cleaning kept her mind and body occupied, but after a few hours she'd scrubbed every surface until her entire apartment gleamed. The idea of going around to John's apartment and cleaning that up came into her head, briefly, but she knew that she'd fall victim to her own libido and he'd see her gorgeous new tattoo.
