David had been hesitant to bring up his fantasy of watching his wife Beth fuck another man, but when he finally did, he was pleasantly surprised that she didn’t immediately say no.

“Is that really something you want?” she asked.

“More than anything,” David replied. “It would be so hot to watch you with another man!”

“Let me think about it” was her reply.

David was anxiously awaiting her final decision, but after a few weeks went by he assumed she had decided against it. They had just finished dinner and were washing dishes when Beth walked up behind him and leaned in close to his ear.

“Ok, I’ll fuck another man while you watch” she whispered next to his ear. “How do you want it to happen?”

He was cold all over and had a knot in the pit of his stomach as he explained his fantasy in detail. Beth would be blindfolded, naked, and on their bed. Her hands would be bound to either side of the bed, and she would never know who was fucking her. Beth wouldn’t know when it was going to happen and would only have enough notice to get undressed and into position. David expected she’d balk at the scenario he laid out, but she surprised him by agreeing.

David spent a week trying to decide which of his friends he would ask. Most were married and the only single male friend he had lived a few hours away. David was resigned to looking online for someone when Mark, his out-of-town friend, texted him that he was going to be in the area for a few days and that he wanted to catch up. David called Mark at once, told him about the fantasy, and asked if he’d be willing to participate.

“Give me a bit to think about it,” Mark answered. “This is a lot to take in.”

Two days later David received a text from Mark that only had two words. “I’m in.”

The men worked out a day and time and another week went by. The day arrived and David had made sure he and Beth would be at home and that the kids were going to be with friends. Around 10AM he received the text from Mark that he was 10 minutes away. David got up off the couch and walked into the kitchen where Beth had just finished eating a late breakfast.

“He’ll be here in 10 minutes; we should get you ready” David told Beth.

“Who?” she asked.

“The man who’s going to fuck you.”

Beth went pale, her eyes wide, as David gently took her hand and headed towards their bedroom. She didn’t resist, but followed slowly, in a daze. Once in the room David wasted no time getting her out of her clothes. Beth had remained quiet and uncharacteristically submissive as he undressed her. She stood there silently and watched as he secured cuffs to the bed for her hands, laid out a towel, set a bottle of lube by the bed, and then produced a blindfold.

Her nipples were hard, and her breathing ragged as David slid the blindfold over her head and secured it snugly, ensuring she could see nothing and that it wouldn’t come loose accidentally. Once he was sure she couldn’t see anything, he led her over to the bed and helped her to lay down on her back. David moved around and secured each of Beth’s wrists so that her arms were out to either side of her body, above her head. Satisfied that she was in position, and could not break free, he left the bedroom to wait for Mark.

He arrived a few minutes later and David greeted him at the door. The two men walked through the house to the bedroom where Beth was secured and naked on the bed. Mark said nothing, but turned to his friend and smiled once he had a good look at Beth’s body.

She had a small belly and B-cup breasts with large nipples that drooped slightly on each side of her chest. Her legs were toned, and she kept her pussy shaved. Her labia were thick and hung invitingly around her pussy. Her brown hair was pulled back in a ponytail, and her chest rose and fell rapidly as her breathing increased once she realized she was no longer alone in the room.

Mark moved around the bed to stand at Beth’s feet and kicked off his shoes. He undid his belt and removed his jeans and boxers but left his shirt on. He stood just under 6 feet tall with an average build and thick, dark hair. David’s eyes went wide when he saw his friend’s cock.

It wasn’t hard yet, but even soft it was thick and long. David wasn’t sure how big it would get, but he knew it was going to stretch Beth to her limits. David’s cock was barely average in length and not particularly thick. Beth had never complained, but he had no illusions about how he compared to other men.

Mark took the lube and poured some onto Beth’s pussy, causing her gasp. She shuddered and moaned slightly as he used his hand to rub it onto her labia and then inserted two of his fingers into her pussy. Her legs moved and she worked her hips a bit back and forth but said nothing. Mark took the lube and began to work it onto his cock and David marveled as it started to grow.

Once fully erect, Mark was at least 9 inches long and thick. He crawled onto the bed between Beth’s legs, took his massive erection into his hand, and began to work the head of his cock between the folds of her pussy lips. He poured a pit more lube onto the head of his cock and David watched as Mark slowly inserted the tip of his cock into his wife.

She flinched and gasped when she felt him enter her but said nothing. Mark eased a bit more of his cock into her, causing her to yelp a little. He continued slowly pressing his length into her.

“Slow” she gasped, “please… I… oh my god …it’s … fuck … so fucking big… holy shit… so fucking big…”

Mark pulled back a bit and waited for her breathing to calm down. His cock wasn’t quite halfway inside Beth. David had moved to where he could see everything and he watched his wife’s chest rise and fall, a sheen of sweat already coating her breasts. He was amazed at how much of Mark’ cock Beth had already taken in. Mark began to slowly press forward into her again.

“Fuckfuckfuckfuck” Beth moaned breathlessly. “Never felt anything like this… soooo fucking big…stretching my pussy…your cock feels so fucking good…”

Mark was now just over halfway in, and he reached over and pulled Beth’s legs up onto his shoulders. Her hips were now angled up and David moved behind Mark to better see what was being done to his wife. He watched as Mark finished sliding the length of his massive cock into Beth and listened to his wife moan with pleasure in a way he’d never heard. Beth’s moans were low, guttural, and primal.

“Fuck me” she commanded. “Fuck me hard with that massive cock and fill me with your cum.”

Mark needed no more encouragement and began easing his cock in and out of David’s wife. He slowly picked up speed, and with each thrust into her Beth would gasp and moan and curse. She begged him to fuck her harder and Mark did as she asked. Soon he was slamming his cock deep into Beth’s married pussy, his balls slapping against her in time with her satisfied grunts.

“Harder… fuck… so…ughhhh… fucking… gooooood…” she moaned, as he slammed his cock into her.

He moved her legs off his shoulders, and she opened them wide as she began a low, continuous moan. She cried out loudly and he stopped, his cock buried deep inside her. David watched as his wife’s hips bucked involuntarily and her left leg extended and began to shake. Beth strained against the cuffs holding her arms in place and her head jerked in rhythm with the rest of her body.

“Cumming… I’m … fucking… cumming…” Beth almost screamed.

Her body shook violently, and David saw her stomach muscles contracting and her legs suddenly wrapped around Mark’s waist. She shook violently and, slowly, her breathing started to return to normal.

“I’ve never cum before” she said once she finally caught her breath. “I thought I had; I’d felt things… down there… but this was the first time I’ve ever truly been fucked. Holy shit your cock is amazing. I want to feel you cum in me. Fill me up.”

He began to thrust in and out of Beth’s pussy, it was stretched out enough now for him to really hammer. She moaned loudly again and shook some more with a second, smaller orgasm. Mark picked up speed and his breathing became heavier as he got closer to orgasm. Suddenly he cried out and slammed his full length deep into Beth. His ass clenched and he shook as he emptied his balls into David’s wife.

“Holy fuck, I can feel you filling me up” Beth exclaimed. “Don’t you dare take your cock out of me.”

They lay like that for several minutes as Mark regained his strength. When he started to pull out of Beth, David moved to get a closer view. As Mark’ cock slid from his wife’s pussy, David saw how stretched it truly was. Her usually tight cunt was gaping open, and Mark’ cum was spilling out onto the towel that Beth was laying on.

David wasted no time getting his pants and boxers off and climbing between his wife’s legs. His cock easily slid into her stretched pussy, and he began to thrust into her. The mixture of lube and Mark’s cum coated his cock and he picked up his pace as he neared orgasm.

“I can barely feel you” Beth said. “Your cock feels so small after that, there’s no way I’m going to cum from you fucking me.”

He came then, adding his cum to Mark’s inside his wife, and Beth laughed. Mark had already dressed and was waiting in the other room when David came out. He hadn’t seen how pitiful David’s cock had been compared to his.

“That was wild” Mark said. “Do you think she’ll want to do that again?”

“I am certain she’s going to want more of your cock” David replied. “I’ll text you once she and I have had a chance to talk.”

The two men said goodbye and David went back into the bedroom. Beth lay there, tied to the bed, with her legs spread wide. Her pussy still gaped open, but not as much as it had right after Mark had finished fucking her. There was a pool of cum on the towel and a small amount still leaked from her pussy.

Beth was silent as David cleaned her up, removed the blindfold, and untied her. She put on a robe that hung near the bed and went into the kitchen for a drink.

“That was incredible, and I hope it was everything you wanted it to be” she began, “but you need to know that I’m going to have to be fucked by that cock on a regular basis now. I’ve never felt like that, and I want it again. Once my pussy recovers.”
