Stephanie lay on her bed, listening to the rhythmic thumping noises coming from upstairs. From the sound of things, her two college student lodgers had gotten lucky, yet again. She'd seen them when they came back to the house, and had waved a quick hello at the pretty young co-ed they'd had with them, as they went upstairs to the boys' room.

Josh and Ben were great boys, she thought, handsome and confident without being obnoxious or cocky. Truthfully, Stephanie was glad to have them around. Looking after this house and her two small children was pretty much a full-time job, and Josh and Ben were almost the only adult company she had, these days. The divorce had been long and bitter, and she was lucky to have kept the house. Things could have been much worse, but she did have to take in lodgers now, to help make ends meet.

Either of those boys could charm the panties off any girl with ease and, from the sounds coming through the ceiling, both of them together had gotten this girl's panties off in record time. Stephanie was glad her kids were away with their asshole father, this weekend. At least she wouldn't have to explain to them what the noises meant. She knew that Josh and Ben made an effort to keep the wilder aspects of their lives from her kids, but still the kinds of noises coming from upstairs right now were just one side-effect of having two young, horny and very sexually active college guys living in the same house.

It wasn't that long ago that Stephanie herself was in college - not even ten years. God, what a lot could happen in ten years, she thought. She must seem terribly old to those boys - a soccer mom with not one, but two small children. But, at least she was still in great shape - at just shy of five feet six and one hundred and fifteen pounds, Stephanie knew she was still trim and attractive, with long, brown hair and curves in all the right places - particularly her natural D-cup breasts, which gravity still hadn't affected too much. But, even a hot soccer mom - a MILF, she thought to herself, with a smile - was still a soccer mom, with too many responsibilities and not enough time for a social life of her own.

Stephanie realized, with horror, that it had been over a year since she'd last had sex - before she'd found out about John's infidelity, in fact, which had kicked off the whole divorce in the first place.

The thumping noises from upstairs paused for a while, and Stephanie could hear muffled voices and footsteps, before the banging started up again. She couldn't stop herself from imagining what was going on upstairs - that pretty young girl getting fucked by those two hot college guys. If she was right, what she'd just heard was the threesome switching around. Maybe that girl was now getting fucked by tall, muscular Josh when before it had been lithe, dark-haired Ben. Was the other just watching - maybe stroking his cock while he watched his friend fucking their latest conquest? Or, were the two of them doing her at the same time, maybe one of them was feeding a hard cock into her pretty young mouth while the other took her from behind.

Stephanie's head was filled with images of the three of them in various sexual combinations as she lay naked in her bed, a very long way from sleep. With a resigned sigh she opened a bedside drawer and took out her trusty vibrator - the closest she ever got to sex, these days, she thought, wryly. She couldn't help feeling it was wrong to fantasize about her two house guests, but how could she help it when both of those hot young studs were banging some girl, right now, just above her ceiling?

Stephanie switched on the vibrator and slid it under the covers until it was pressing on her mound and she could feel gentle vibrations in her pussy. As she slid the vibe over her fleshy outer lips, she started to tweak her nipples with her other hand. All the while, she was imagining the two boys upstairs - their hard, young bodies as they pounded that little co-ed slut for all she was worth.

Stephanie started to stimulate herself more directly - pressing the tip of the vibrator next to the hood of her clitoris. She pinched her nipples harder as the vibrations brought her closer and closer to orgasm, a soft, low moan coming from deep in her chest as her back started to arch.

Suddenly, there was an angry female voice shouting upstairs. Stephanie couldn't make out the words, but it was very clear that the girl was unhappy about something - from the crashing noises upstairs, it sounded as if she were throwing things. Stephanie heard loud footsteps stamping down the stairs, and then the front door being slammed so hard, she half-expected to hear the glass panels shatter.
