Experiment with the unexplored experiments

Mark couldn’t think of something just yet, but he knew of something he could do to really make her happy. He could do some of the experiments without her and record the effects.

He looked through the list again and made a list of which experiments were not complete. He then subtracted the ones that he knew his wife would be needed for or that were too dangerous to be done alone. That left him with test 7, 8 and 16. He had considered doing test 10 but ended up a bit scared about an object being stuck inside him.

He decided to start with test 7. He went upstairs and grabbed a pair of cheap old underwear. Mark knew Hellen would buy them new clothes soon as they both only had a few sets of old clothes. Which meant that ripping one pair of his underwear wouldn’t be too bad.

He first ripped some small holes in the boxers, small enough to consider them broken but not big enough to consider them unwearable in an emergency. He took off his wife’s pants and underwear revealing her pussy to the chilly bedroom air.

Putting on his ripped underwear it took a bit longer to tingle but tingle it did none the less. Mark eventually felt his pussy close and expand to a growing set of balls and his trusty penis. Pulling down the boxers he checked whether there were any malfunctions due to the ripped nature of the underwear, but it looked, felt and reacted like his normal penis would.

He then put his wife’s panties on to change back to her groin to proceed with the test. He switched again back to his own underwear but started ripping it while the tingling started, creating bigger holes but keeping it, if barely, wearable. As if responding to the tingling and transformation slowed down. What normally took less than half a minute now took nearly two minutes.

Mark made a mental note of it while switching back to his wife’s vagina for the last test in regard to the broken clothing test. He tore his underwear to kingdom come, making it just a few strands of fabric on a waistband. He then put them on and waited for the transformation to happen but after 5 minutes he was convinced they wouldn’t.

“This means the state of the clothes determines how fast the transformation is and if its unusable for its original purpose the transformation won’t happen. I wonder what would happen if my boxers would be repaired, would they then work again?” Mark wondered before falling silent for a moment.

He started smiling and giggled. “I sound just like Hellen now that I’m doing the experiments”

Putting back on his wife’s panties, he prepared for test 8 by grabbing his own underwear. He waited for the tingling to stop and then put his own underwear over the panties. The tingling started but it felt a bit odd to him, as if it was moving over his skin in different places, he then felt the now familiar sensation of his penis pushing out of his groin, followed by a wedgy pulling on him. His wife’s underwear was not designed for a male’s groin and resulted in it digging into him. He quickly pulled both items down, freeing his slowly erecting member from the soft fabric prison it was held in.

“All this shifting is making my body feel all horny.” He sighed.

Looking down at his wife’s body, he saw his impressive member sticking straight off of her. It felt out of place, yet he couldn’t help but like how it looked. Grabbing hold of his cock with his wife’s smaller hands he realized how large his cock looked on his wife’s body. He could barely get his fingers around it and needed both hands to cover the length.

“Fuck, I didn’t expect this to be so hot.” He murmured while slowly stroking himself.

The idea of watching his wife with a massive cock made him horny, something that he had never thought of before now. He wanted to see her stroke her cock for him. No, he needed it, the mental image wasn’t enough nor was his first-person view. He turned to the wall where there was an old-fashioned mirror on the wall.

A smile grew on his face as he stood in front of it. There he saw her, his beautiful wife, stroking his cock, no, her cock. She was grinning at him, not in her usual way when she was mischievous but close enough. She was slowly playing with her cock, teasing the tip whiling looking at him.

His wife let go of one hand and started massaging her breasts with it. He could hear her moan softly as she twisted her nipple. Her face was flushed, and she was starting to get into it, he could tell. She was gyrating her hips while increasing her strokes. Her cock was wet and glistening with precum. ‘She is so hot, fuck’

His wife was really getting into it and wanted to tease him some more, she twisted and pulled at her nipple before letting it go. She didn’t want him just hard, she wanted him rock solid and twitching. She knew how to get him there, like she always does she puts her finger in her mouth and starts sucking on it and licking it like a cock. She even started sucking it in rhythm of the strokes of her cock, causing not only his cock to twitch and squirt precum but her own as well.

With a pop and moan she pulled her wet finger out of her wet mouth causing a string of saliva to drool out. “Do you like that big boy?” she asked as sultry as possible. “I bet you did”

She rubbed her saliva over her cock and started rubbing it with her wet hand. He could tell based on her grin that she had a slutty idea. “Now that I have this big hard cock, I do wonder something”

She used her finger to scoop up some of the precum stuck out her tongue. She rubbed the precum onto her tongue before pushing it in and sucking it off. His wife was savoring the salty taste of her own precum while jacking off her cock.

She moaned deeply, enjoying every moment, and sped up her strokes. He could tell she was getting close. “I want to cum so badly dear, do you want to see your wife cum with her big girl cock?” she moaned.

Hellen grabbed her breasts again and started massaging them. She started biting her lip and was shaking violently but didn’t take her eyes off of him and he didn’t take his eyes off of her. “Fuck, I wish I could fuck you right now, I want to fuck your pussy and your face. Mhm, even your ass.” She panted.

“Fuck I want to cum deep inside of you dear, please accept my thick cum!”

“Fuck, Fuck, FUCK!” she screamed before ropes of cum shot from her massive cock and hitting the mirror, seemingly covering herself in her own spunk. A few more spurts came out, leaking onto his hand and thighs.

“Owh fuck, that felt good.”

Mark felt a slight urge to lick up the cum but ended up snapping himself out of his lustful and blissful state. Realizing what he had just done, and realizing that he had liked it. his cheeks flushed red again but this time out of embarrassment.

“Fuck.” He mumbled.

His thoughts were racing thinking about what to do with his newfound fantasy. The orgasm was amazing, and he never felt so horny, though he had to admit he never thought about it before. He tried to explain away the sudden horniness and his behavior with the rapid transformations but deep down he felt that might not be the only reason. He quickly cleaned up the mess he had made and tried to calm himself down.

He still wanted to finish some of the tests before Hellen came back and he had just wasted valuable time.

Mark put on his own underwear to cover up his penis and grabbed Hellen’s panties. He sprinted out of their bedroom and down the stairs towards the door. He wanted to test whether outside the mansion the magic would still work. He was still a bit scatterbrained from the intense orgasm and had forgotten to grab a pair of bottoms for himself. Once outside he walked away barefoot from the mansion and at a far enough distance swapped the underwear to Hellen’s panties.

Low and behold Mark started shifting, the magic seemed a bit slower outside, but it still managed to do the impossible. Once the transformative sensation stopped, he started making mental notes of his findings, only to stop and think about his situation. He was standing there, outside his home, half naked, swapping underwear and smiling like a lunatic. He quickly grabbed the underwear and sprinted back into the house.

“I’m so happy we don’t have any neighbors in sight.” He sighed before he closed the door behind him.
