A looooong minute

"Okay, clock starts now!" Olive said, holding her phone. She pressed a button and turned her phone down to face Steven, showing him the timer app running.

"She's got this," he thought, "It's already been a few seconds. She just needs to keep this pace. This can't be doing anything for her. It takes a while of hard pounding for her to cum." He was desperately trying to reassure himself, unaware of the mad desire already growing inside of his wife.

After about ten seconds had passed he noticed that Diana's pace had quickened slightly and she was now pulling out a few inches before sliding back down. "What is she doing?" he thought.

"Uh, babe?" he asked aloud.

"Ha... Don't worry. We are still good. Mmmm. This is just...." She trailed off, breathing heavier.

With a long sigh, she pressed herself back, pushing into Olive's lap with a slow deep thrust before pulling out further than she had before. She was now halfway out, about seven inches, before sliding back down a little harder. She kept going at this pace, quietly gasping.

It occurred to Steven that he would have slipped out well before this point, and Diana was only half way up Olive's incredible length. And the half that was still inside of his wife was again more dick than he could have given her, and that wasn't even accounting for the girth. He had never seen any woman stretched to this extent, let alone his wife.

20 seconds

"Ooooohh!" Diana's high pitched whimper accompanied trembling in her legs.

"Um, babe, just slow down," Steven pleaded.

"I, Mmm, I can't!" her voice sounded an octave higher than normal to Steven, "Fuck! Ugghh! I can't fucking stop! I need more!"

"Oh no," Steven thought.

30 seconds

Diana's pace had quickened and Shelby rode Katie's pole to match the depth and rhythm. Everyone in the room was moaning except for Steven.

Diana began pulling away further and just like in Steven's nightmare, her pussy was pulled inside out slightly with each thrust, like it was hugging tightly, not wanting to let go.

"Oh fuck!" Diana shouted, "She is going in and out of my womb! Ugh god!"

40 seconds

"I'm sorry Steven!" Diana cried, now sliding up and ramming herself back down a length twice that of Steven's. "I can't fucking stop! Fuck! It's so fucking good when she is fucking my womb!"

Unable to help herself, Olive reached down with her free hand to grab onto Diana's wide, childbearing hips.

"Oh yes! Oh fuck! Please fuck me, Mommy!" Diana begged, "Your cock is so much bigger than my husband's!"

"Oh my god! Your pussy feels so, ugh, fucking good!" grunted Olive.

50 seconds

"Oh shit!" Diana cried out, as she began hammering herself down onto Olive. "I'm cumming! Please don't look, Steven! Oh god! Oooooohhh!!"

Steven had never heard Diana make any sounds close to the cries and moans that were now erupting out of her. He could always get the occasional "Oh god!" or "I'm cumming!" from his vocal wife, but that was nothing like the high pitched, **** squeals that she made now. It was made apparent by her cries and incomprehensible swearing, that Diana was having an orgasm on a whole other level compared to anything she had felt before.

Olive put down her phone so she could grab Diana's hips with both of her hands. With a firm hold on her toy, she was now able to slam in and out with her full length. She was in control now, and she didn't care if Diana was ready or not.

"Oh fuck, I'm gonna ruin your tight fucking pussy," Olive said, panting with the effort she put into ravaging Diana. "You fucking want that, don't you? You want me to ruin this pussy for any other dick?"

"Yes! Oh fuck yes!" Diana responded happily, "Claim my pussy! Oh god please claim my pussy, Mommy! It belongs to you!"

Helpless, Steven could only stare as his nightmare came to life. A satisfying, wet, slapping sound accompanied every thrust that buried Olive's third leg into his wife. Her heavy softballs rocking back and forth with the motion, Diana's endless stream of love juices dripping off of them onto Steven's face and into his open mouth.

Olive's dick looked to be almost as thick as Steven's bicep, and it was beautiful. Every time it disappeared inside of his wife, he almost felt like he missed it. Being this close, he could see every detail and shape the tight skin made as it contoured the bulging veins. The gorgeous cock itself, being tightly contoured by Diana's inside out pussy as it tried desperately to hold on to the slick shaft that was giving it so much pleasure.

For minutes Olive tirelessly continued her relentless pounding. His wife didn't seem to tire either, despite being brought to orgasm with each thrust. This too must have been due to the same futa-magic that had caused every other miraculous change to occur.

When the ravenous pistoning finally slowed and stopped, Diana fell off of her mount and collapsed on top of the squirt-soaked Steven. She laid there panting and moaning softly, her legs shaking. When Steven looked down at her straddling his chest, he could see the "damage" that Olive had done to her.

Her half-football shaped, prolapsed womb was pushed several inches out of her gaping pussy. It's entrance at the tip was swollen and loose enough that it looked like he could fit his whole cock inside without touching the walls.

"Oh fuck yeah, that is hot! Look what I did to your wife," Olive teased, "Oh and she came with only five seconds left by the way. I stopped the clock as soon as I felt her pussy start squeezing down on me."

Despite the feeling of defeat, a strange calm swept over Steven. He was in some way relieved that the "test" was over. All that was left for him to do tonight, was to give in and try to enjoy himself as best he could. Though he imagined that wouldn't be too hard. He was painfully aware of how aroused he was by the sight of his wife losing herself in a pleasure he couldn't hope to give her.

But he was still concerned for his wife, who appeared to have fainted. "Diana? D, are you alright?" he asked.

"Oh she's out, hun," answered Shelby. Her blonde hair was matted with sweat and stuck to her blushing cheeks. She had apparently also enjoyed herself and was gently grinding back and forth on Katie. When she slid her hips forward he could see the tip of Katie's insanely long cock, bulge out just below her rib cage.

How that experience wasn't painful to Shelby, was beyond him. Instead she seemed to enjoy it more than anything else, and she even pressed down on the bulge with her hand to add more pressure, massaging Katie's cock-head.

"But I know just what'll wake her up!" she continued. Dismounting Katie with a wet sloshing sound, and a small deluge of pussy juice, she knelt beside Steven and the resting Diana. She then reached down and began massaging Diana's outstretched womb with one hand.

Diana writhed and gently moaned in response. "Uh... That's. That's good!" she said, half awake.

Stroking her wet and swollen womb with one hand, Shelby pushed three fingers inside of it and began swirling them around.

With a start Diana came to. "Holy shit!" she shouted, "Did I pass out? And fuck me, that feels good!" She was now back up on her knees and smiling at Shelby as she continued to stroke and massage her "insides".

"Did I make it?" she asked, smiling.

"No, you just couldn't help yourself," answered Olive, "My dick feels too good doesn't it?"

All the women were giggling with each other and sighing in their state of euphoric pleasure. Olive and Katie were stroking themselves proudly, while Shelby stroked and now gently fisted Diana's exposed womb.

"Oh sh..shit!" Diana said, not appearing very disappointed at all. "I'm sorry Steven, but Olive's cock... It was just too much! You have no idea how good it feels to finally be filled up like that! And she could keep up that pace for soooo long. God, I've never been fucked like that."

Steven shuddered at those words. He knew he would have finished seconds into pounding that hard and fast. Especially if he could ever experience his wife's pussy squeezing down that tightly. "God what must that feel like?" he thought, "To be so big, that you can stretch somebody like that. My wife must have felt like a virgin to her."

"Oh, Steven!" Diana gasped, noticing how hard he was. "You poor thing! Your poor little cock is so hard from watching Mommy fuck me!" she spit on his cock and began stroking it, deftly twisting and teasing his sensitive head. "You liked watching didn't you?"

".....Yes," he replied.

"Did you see how hard I came? Oh fuck Shelby, that feels good! Did you see me take that big, fat dick all the way?"

"Yes"

"Thank you baby! Thank you for sharing me with Olive!" she said as she started to dismount him. "I know you want to fuck me baby, but right now I need more of Olive's cock."

She gestured for Katie to give her some room as she laid down on her back next to Steven. "I really am sorry honey," she said, as she brought her knees up on either side of her beautifully, full breasts and held onto them with a hand behind each knee. "I'm still your wife, but I'm Olive's cum-dump tonight. Oh fuck this is hot! Olive is ruining me, and you can't do anything about it!

"Oh fuck. I'm sorry but this is sooo hot!" she continued, "Please try to enjoy it! I want you to experience this with me. I still love you."
