It was a rainy afternoon and this gorgeous girl was lounging around in her apartment when there was a knock at the door. She hadn't been expecting anyone. She wore only an oversized knit sweater, which hardly covered her black cotton bikini bottoms; her most comfortable panties. They traced her firm bottom quite perfectly. Generally on the conservative side, she'd dress modestly. She'd never be seen like this outside the comfort of home.

She arose curiously to answer the door.

She'd thought perhaps it was the late lunch she'd ordered. She peered out, hiding behind the door. only open a crack. She swung the door open when she saw it was you..Surprised and happy to see you, her husband's best friend, also a good friend of hers, she'd forgotten why she'd been hiding. She tugged awkwardly at the bottom helm of her top to consealed herself, realizing her mistake. It was too late, now. Her full, meaty lips filed out the thin panties. The cotton-spandex blend fabric had pulled tight. Fitted, it outlining her perfectly beneath the top which shrouded her slender frame. Her lips peaked from the corners of the fabric not spaning the gap between her legs. She failed to hide herself completely, though she thought she had as she stood in front of her male friend.

Regardless, with a sense of hospitality, she invited you in. Not leading, but walking rather naturally ahead into the lamp-lit living room. She sat where until moments ago she'd been reading a book. She placed it aside, expecting you to sit, giving you deserved attention.

Having decided to stay a while, the two began to play a game; Mario Kart, on the old game system. She wasn't very good, yet competative and a good sport none-the-less. She lost, letting the controller down too early. Watching as she recoiled from the vibration, it gave you an idea. She pulled the controller away rather quickly, responing to the sensation the controller had given her as she rested it against her pelvis. Her character spun out as she lost the round.

Ideas began to formulate. It would be the beginning of an interesting night. Suggesting another round, it was decided that there should be some new rules. There would be a point system. The next player to fall off the track would get a point against them. It hadn't yet been decided what all that meant, but in no time, she'd accrued several points. The numbers were stacked against her. She owed you something. If she lost the next race, she'd have to hold the controller a certain way. It need not be explained that you'd do everything possible to cause her controller to vibrate. She wasn't one to use toys, so this was a little new to her. Of course she'd heard of such things, but the experience was new to her, the sensation quickly drove her over the edge, a wet spot appearing. She became faint as she came in front of you.

Embarased, she slowly recovered, There wasn't much she could do except play again to get you back. She didn't know how she'd get you back, but she wasn't going to let you have such fun with her and get away with it!

As a side note, though she'd never admit, she was quite hot and bothered, now. She would have trouble saying 'no'. Unfortunately she hadn't seen her husband in several weeks and here you were.

She had no idea how you'd fantisized of her or that you'd thought about how you might have your way with her while your friend was away. It was the perfect opportunity to take advantage and take what you'd always wanted; her.

She'd never been one to play with herself, not wanting to stir up excitement if not to be gratified. This was a recipe for disaster and she knew it. Top it with a coupe shots of tequilla as she lost the next few rounds and soon she'd wager her top. Perhaps it was just her top, but revealing her cheet to you was a feat in itself. As exillerating as it was to be seen, it was embarassing for her. A shy girl, swimsuits asisde, no man had seen her, aside from her husband, of course.

However, she'd agree to play your game. Though you'd ask her for more than she was willing to give, let alone offer, in effort to please, she'd suggest a compromise to get out of it. Sticking to her word, she'd follow through. Her top led to her sitting in your lap, allowing you to cop' a feel, hands running over her breasts, tweeking a nipple and following her curves as you gave her a little tug inwards, towards your lap. Soon your boxers came off. Luckily she was still wearing her panties or it would be really awkward to still sit on your lap. Well, those were next to go. Skin on skin was too much for her. She felt her pussy lips touch to your cock as you sat her back down where you wanted her.

Outercourse meant she'd have to dance a little around the tip. Slipping it in was easy, as you took her by the hips and moved her about with ease. She felt your pre-cum leak out inside her as your dick throbbed. It terrified her. She thought you'd came.

Eventually, well, she'd offer herself. More of herself than she'd given her husband, offering to do things for you she normally wouldn't do.

"Double or nothing", she pleads one more time.

"I'll do ___, if you'll give me a chance to get out of ___. I promise.", she'd say. A blowjob until you came in her mouth. It was better than having to let you fuck her. She'd let you cum on her pretty face, She'd just sit there while you'd get to tweak her sensitive little nipples, lay there as you explored her and got to play with her pussy. She'd never let him do that; too sensitive and intimate!

Finally it came to this, and it was only the begining. She had to let you actually put your cock inside her, but only for one minute. No thrusting, but you'd made her let you go without a condom, even though she was worried you might impregnate her. Having already agreed earlier that condoms wouldn't have to be worn no matter what, she couldn't say anything. You'd tricked her. It was back when she was negotiating with you over a blowjob. She'd had to not only let you, but make you finish in her mouth for the first time in her life. She should never have been even giving you head, but that was a differnet story. Now, unable to make you to wear one, and having to let you do something, she made this concession.

No thrusting allowed. It would mean no enjoyment for her, but this wasn't at all about her enjoying it.

She was to lay back and allow you to slip yourself inside her, like a tight new cocksleeve and keep yourself there for one whole minute. She began to worry when she felt you start to throb. As promised, thirty seconds in, she'd start to stroke the base of your cock while you were still inside of her. Effectively, she was masterbating you, and she wasn't allowed to ask you to pull out. Again, she felt you throb as she was jacking you off inside herself. Not once this time, but a few strong hard pulsations. She counted down the seconds, only getting to 43 when she felt you cum.

What a disaster! She was escentially impregnating herself for nothing, getting nothing out of it, over a bet. She didn't even have the pleasure of a good fuck! Alternatively, she might be on top, having agreed to outercourse, jacking you off with her pussy, but having agreed to slip it in for 10 seconds. Following through, she put your cock inside her only a moment before you blow your load, pumping your load inside her as she stuggles against pulling out.

You might taunt her a little while it's happening, only feeding her regret, lifted her hips, only to let herself back down and feel you shoot another load inside her.
