She felt you holding her, one arm around her waist. One hand under her thigh, held her leg up to her chest. You held her whole body in the air above you, dangling her above your cock; floating, in limbo.

Your cock throbbed and touched her; an intense feeling of threat..

She was laughing, as if it were a joke! As if you were only threatening to place her down in your lap as you held your stiff cock, aimed up at her. The head rubbed up and down her tight slit, spreading her lips as you held her over it, lining it up, lowering her slightly, playing with her; threatening to enter her -but you wouldn't, right? You wouldn't do that to your best friend's wife, right?

Perhaps this was under the guise of 'play', 'just the tip', or 'try for size'.Reference: /r/measuringup

Would you use her as a cocksleeve? You held her as if she were a toy.

Can you imagine if you took her by the hips and placed her down, sliding her down the length of your cock, sheathing it with her body as if she were your own personal pocket pussy?

You know the ones that emulate the human body in the shape of an ass that you can hold?

Perhaps that's all she was to you in this moment.

What if by the time you slid her over yourself, enveloping your shaft, you started to lose control? She might feel your cock tense up and wonder. She might feel it begin to throb, slap you thigh and warn you, asking if you were about to cum... still shocked that you'd socked yourself with HER.

Would you pull out? Would you lift her, or try to contain yourself as she began to squirm? Her pussy tensed back, contrating as she felt you begin to pulsate inside her. She knew well the familiar feeling of one who is about to lose control...

Would you pull out and try again, or use ...her, to help you finish?

Is she just a fleshlight to you in this moment?

__ The premise:

I'd want to create some story around the event. Certainly, building up to what this moment is. I'd encourage you to read other earlier prompts which detail further, explain the situation and might give you some ideas, as well.

This is a bet -one she shouldn't have agreed to and now regrets.

Double or Nothing; no condom and no pulling out (and not just because you don't have one).

I'd like to avoid romance, or the idea that she might fall in love with your dick. Obviously, there'd be some passion between characters, but not in a romantic way. It would build as a purely sexual. The idea of your character stealing her away from her husband should never come up in the story.

I am 18 and all participants and characters must be 18 and fully concentual; her perhaps not confused by what's happening. For the sake of arguement, she'd agreed to the bets up until now, but the outline of events described are impromptu and unplanned, unexpected on her part.

This is meant to be dubious, dub-con with an inherent risk of her getting pregnant. No attempt should be made to convince her of less risk; infact, the oposite, you might choose to taunt her about the potential risk and the fact that she can't go back on it --that she might very well end up pregnant.

She looks down, feeling you throb inside her, terrified and watches it happen.

I'm looking for creativity and ideas of your own.

Build up to the betting, from innocent and non-sexual, to losing her top, having to give you head, etc.

TL;DR: Her boyfriend / husband is away, working hard. You dropped by with hidden intent to entrap / use her and pleasure yourself via games and getting her to wager a bet, eventually leading to her having to accept the risk of potentially getting pregnant behind her husband's back.
