Going along with my prompt in which a good friend gets to fuck his best bud's wife over a night of betting and laying¹ wagers...

It starts where the three of you; you, your buddy and his wife had planned a game night. Only, it turns out he can't make. Not wanting to be bored, his wife is still interested in getting together, giving you the oportunity to have a little fun.

Perhaps this is the opportunity you didn't even know you were waiting for, or maybe you'd been waiting for a chance like this for a long, long time.

What would you do? How would you turn an innocent game into a way of getting in her pants?

PLEASE DON'T say strip-poker, or any other version of 'loser has to take of their clothes' --so cliché.

Please understand: she's a loyal, loving wife of your friend. She's happily married and has no intention of cheating. She thinks her husband does just fine.² You'd have to work your way up from simple things to more intense bet¹ as she'd never straight up agree to playing a stripping game; let alone fucking!

Marking her body.
At some point in the game, you might tell her you that you get to write things on her body with this handy Sharpie marker you found in the drawer. You never said what kind of things and quickly that escelates into the teasing her with things you'd like to do with her body; things you'd like to put certain places. Perhaps writing instructions for yourself of where you plan to finish - 'cum here', to which she might might chuckle at and argue. Embarassed about what you're insinuating, what can she do? Now she's got to let you write whatever you'd like.

You'd take photos and update her husband about the ongoings of the night through the group text you had going used to plan the evening.

Tonight was supposed to be game night for three. You, her and your friend; your best friend. Only, he isn't home.

It turns out your friend wasn't going to be able to make it back in time. I don't suppose you care.

It's just the two of you, now. Some bets are made by you, basically telling her how it is. Others might be made in the group message conversation. Leave him guessing, unsure what he's being asked. What will the out-cum be? What if what he says esentially makes or breaks it? Enlightening him with an image of your new found cock-sleeve.

You waltz in us if you own the place. Take a seat in your friends favorite armchair, where you'd soon claim a blowjob as a prize. His wife would make a face and trying not to gag as swallows to fulfill her end of the bargain.³ It was a tough choice between the arm chair and his favorite spot on the sofa, but you could still bend her over the armrest, later! Having taken so much already and before the night was through, you'd no doubt win the ultimate bet:
Double or Nothing; No condom, and no pulling out!

You'd have to get their in baby steps still, teasing your way up to it, give a little to get to the next step and when she fails again, you offer to 'let' her let you slip inside... no condom of course!

You'd get to fuck her, giving her the illusion that you plan to pull out, IF she manages this next round (with you inside of her), distracted.

Game ideas: Use whichever one(s) give you the best ideas!

• Mario Kart or SuperSmash!; despite her lack of interest or talent playing v-games. After all, you weren't really here to play games tonight, were you?

What'll it be? A wager on Cards? ...or the ultimate game of Smash? Make sure it's a game she's bound to lose! ...even if she wins.

All bets and rules added pertain to all future bidding!
That means, if you announced you felt you might be cumming soon, you won't be pulling out! Because ealier for the blowjob she had to keep it inside (her mouth) until you finished. Nothing changes just because you're inside a different hole!

Her face grew cold at the realization.

So there she was... Quivering, shaking; trying her best to hold it together as she pushes herself down, sleeving your thick cock; trying to complete the bet she made, for a chance to get out of the previous wager that she never should have made -and the one before that which had her topless, then on her knees letting you spurt cum in her mouth.

She never imagined the night would turn out this way!

Things you might say to her husband:

• "I hope this doesn't ruin our friendship, but it'll be so worth it!"
• "She's a little tied up at the moment."
• "Last chance to ask me to stop..." -but you get no response.⁴
• "Sorry bro, she gave your blowjob to me..."
• "I promise I'll pull out, after I cum!"
• "You get to keep your girlfriend/ wife. I just needed a fuck doll for an hour."

Things you might say to her:

• "As long as I can pull your hair while I empty a nut inside you..."
• "Good thing you're on the pill...", to which she'd respond with regret, "...I'm not."

My favorite idea; and what I'm feeling ...
Please build up to and include:

• Body Writing; obviously.
• Blowjobs > Must be required to finish CIM.⁵
• Acting like she's just a fuckdoll.
• Sit her in lap to be manhandled.
• Using his dick as a dildo!, she'd never used a dildo before, doesn't own one. Maybe she should just use 'yours', like it is one.
• Edging / Outercourse (until you maybe slip it in).
• Trying her out as a fleshlight. Who would pull out of a fleshlight?!
• 'Cum Roulette': She must extract the cum from the players dick with her--> pussy lips?
• Pocket Pussy "I bet you actually have a pocket Pussy", she mocked. "You probably use it every night." She was discussed at the thought as she even said it. Your response shocked and disgusted her even more. "I'll make you my Pocket Pussy!". "You wish!" she shot back in a snarky tone. That was the next bet and for her next turn she had to lean back over your lap as you took her by the hips and guided her down on your stiff cock. She felt her pussy part and opened up. Sheathing your thick cock, she let out a stiffled moan as you slid into your 'pocket pussy'.
• No option for wearing a Condom.
• She's not on the pill...

Something about violating a pussy that is lovingly sworn to another man is so hot! I am 18 and all participants and characters must be 18

TDRL; Fuck and impmpregnate your friend's wife while he's away, by way of making bets and wagers.

¹ /dictating acts, wagers and forgeits, rather.
² biet you'll obviously do better.
³ she'd never done that for anyone before -not even him.
⁴ because his phone died or he'd gotten on a plane.
⁵ which would be gross for her... She'd hate it. He'd be jealous.
