Let her take the lead.

"Yes..." You confessed. You did indeed want to fuck her, but you were enjoying the foreplay... Foreign as it was, there was a certain level of intensity that you'd not experienced before.

"I thought so." Emily said. "But if that's going to happen, then you have to be good..." She told you, once again her bottom lip brushing the head of your cock just barely. "Will you be good and do as I say?" She asked, and with every word she uttered, her lip would gently make contact with your member.

"Yes." You agreed in a semi-groan.

"Good boy... Now you just lay still like that." She said as she sat up. You hadn't noticed until now but her short black dress was quickly riding down her body. She let the dress continue to fall as she stood up, the thin fabric falling off her easily. She had no underwear on.

You stared at your naked fiance standing over you. Her perky and full breasts and swollen snatch drawing your undivided attention. She stepped forward slowly on the mattress so that she was standing over you.

"Do you like the view?" She asked in a soft, husky tone.

"Yeah..." You admitted. You were staring up at your naked fiance, her swollen pussylips beginning to glisten from her wetness, and her heavy underboobs perfectly shaped and hypnotizing.

"Mmm... Good... Keep looking..." She said as she reached down and slowly pinched her clit with two fingers. She moaned softly as her fingers rubbed in a circular motion, her other hand also moving down to spread her pussylips. You continued to stare at your fiance's beautiful wet snatch and breathed raggedly as you watched her touch herself. You'd never felt your own cock feel so painfully hard, though.

Emily slowly lowered herself until she was on her knees, her pussy merely a few centimeters from your face. She continued to rub herself, her wet labia spreading coating her fingers in a sheen. She moaned again as she slid two fingers inside herself, and you watched like a madman. You began to reach down for your own cock, but Emily grasped you by the wrist quite tightly.

"You're not allowed to do that just yet... Only good boys can do that, do you understand?" She asked. You nodded meekly.

"Good..." She uttered softly as she ran a hand through your hair, the other still fingering herself and her grinding hips rubbing against your upperchest. "Now prove that you're a good boy..." She ordered you as she thrust her hips forward and pulled your head into her pussy. You gasped then immediately began to suck on her privates. Your mouth and nose was covered by her swollen and wet snatch and you struggled to breath, but you continued to slurp. Your tongue probed her pussy, running along the labia on either side and gently pushing into her hole. She moaned and rubbed her pussy into your face even harder. You felt your tongue brush against her taint and even her ass as she grinded her hips aggressively. You squirmed as you forgot the need of oxygen and felt your pre-cum dribble down the side of your untouched cock, and she rewarded you with a few short breathes before suffocating you again with her saturated pussy.

You gazed up at her perfect body towering above you. She looked down at you with her lustful and almost sadistic smirk. She paused a moment and watched you squirm for a breathe, and you swear that she was getting wetter just by watching you buried in her pussy. She slowly lifted herself up off your face and easily slid another finger into her soaked cunt. She moaned and smiled, the sadistic expression still etched into her face.

"Okay, it's ready... Thanks for being a good boy." She said as she climbed off you and off the bed. You began to get up too, ready to fuck, and she pushed you down onto the bed with a pitying smile.

"You stay there." She said as she reached down under the bed and pulled out a small bag. From it, she took out a thick, eight inch dildo. You frowned when you spotted it and she smiled at your expression.

"This... I've named it 'Dennis'... is going to fuck me." She said, her smile widening from your expression which was alien to even yourself. You wanted to see Emily fuck that dildo, but you couldn't quite bury the feeling of betrayal.

"You've already helped out and now Dennis can fuck me easily thanks to you." She said. You slowly nodded.

"Good boy... You sit there and do as I say." She ordered you. You remained seated as Emily climbed onto the bed. She faced away from you and bent forwards, her beautiful round ass and wet pussy on full display.

"Now, give me a quick service... Lick me up." She ordered. You immediately dived down to suck at your fiance's pretty pussy from behind, hungrily sucking her labia and clit and letting your tongue slide inside her. She reached back and grabbed your head then twerked her sexy ass in your face, your tongue leaving a wet smear over her asshole and pussy.

"Good boy. Now sit there and watch Dennis fuck me like a man." She breathed as she reached around, positioning the dildo below her pussy. She slowly lowered her hips so that the head of the fake cock pressed inside her. She moaned lewdly and rubbed her clit as she lightly bounced her ass up and down, the dildo probing further and further inside her.

"Fuck... He's so thick..." She gasped as the dildo continued to edge deeper inside her.

"Uh huh..." You agreed without realising, your eyes glued to your fiance's cheating snatch. The dildo was completely coated by Emily's slutty pussy juices.

"Do you like what you see?" She asked in a quavering voice, her pussy sliding up and down as the thick dildo penetrated her further each time.

"Yeah..." You said, again not even registering that you were speaking.

"Mmm... He can barely fit inside me... Uh...!!" She gasped again as the dildo slid completely inside her. She pinched her clit and crumpled on the bed, her ass and pussy shivering from the feeling.

"Dennis is fucking me so hard... He's getting so far inside me.. I didn't even know that it could go that deep." She gasped each word as she fucked herself with the dildo.

"Ugh... Fuck..." You groaned from the torment.

"You've been a good boy... a good little boy... You can touch yourself now if you want." She said. You immediately grabbed onto your cock and began to pump it while watching your wife fuck a dildo.

"That's right... You like watching your fiance fucking Dennis, don't you?" She asked.

"Fuck... Yeah..." You groaned.

"Dennis can fuck me whenever he wants to... Even if you're not here." She moaned, her hips bucking and the fake cock burying deeper inside her. You could hear her wet squelch with the movements.

"Yeah...? Are you going to fuck Dennis when I'm at work...?" You asked, heated from the moment. You continued to tug at your cock while watching and listening to your slutty fiance.

"Mmm... Of course... Who knows, Dennis might even have a friend he wants to bring over while you're gone... They can both fuck me..." She whimpered and bucked her hips.

"Mm.. But I'll want to watch too..." You said dejectedly.

"Maybe we'll send you a photo." She said.

"Ugh... Fuck... I'm gonna cum..." You groaned as you rubbed your cock.

"Mmmm...! Cum while you watch your fiance get fucked..." She moaned lewdly in a high tone. You could tell she was close too and before you knew it you were hunched over and groaning as an orgasm washed over you. Emily ground her hips, the dildo almost getting swallowed entirely by Emily's hungry slit. She gasped and moaned loudly as she bounced on the dildo.

"Fuck...! Fuck I'm cumming... Mmm!" Emily moaned. You came on her ass, hot lines of semen dribbling from your member, and Emily collapsed on the bed, shaking. You laid down next to her, panting.

"I didn't know you were into that..." Emily said, looking at you mysteriously.

"Well... uh... I guess when we're roleplaying like that..." He said, embarrassed.

"Good to know..." She said, giving your shrinking cock a light squeeze before kissing you on the cheek and rolling off the bed. She walked out of the bedroom, still naked, her ass swaying with each step.
