She Dares Him to Go Ahead and Masturbate

"...just go ahead and masturbate already," said Kate finishing her sentence. "In fact I dare you to do it and cum right in front of us, if you can do that then I'll definitely believe these ridiculous claims you're making."

"But Kate, I don't think your mom would be okay with—" Megan started to say before Kate cut her off.

"Relax Megan, he's fucking with us," Kate said to Megan. "John doesn't have the balls to do something that bold."

"So you'll really believe me if I masturbate in front of you like I wanted!" John said excitedly.

"Oh my god please kill me before I humiliate myself anymore," John thought. "Please God I'm begging you, I'm sorry."

Deep down though John was getting so horny that despite his objections in his mind and attempts to resist the curse, he was surprisingly eager to start masturbating, despite the fact that Kate was his sister and Megan was her friend, he's never been this horny before. Everytime he thought about talking about his exhibitionistic side, had an exhibitionistic fantasy, or considered acting on his exhibitionistic urges he immediately started feeling 10 times hornier than he already was. It was starting to drive him crazy, it was getting hard to focus. And for whatever reason the embarrassment of finally confessing to all this stuff was only turning him on more. He was **** for an opportunity to backtrack, to claim it was all a joke, but this curse was forcing him to say all the humiliating things he wanted to say but was too embarrassed and afraid to. Plus ever since he had the desire to start jerking off in front of Megan and Kate until he managed to cum with them watching, the urge to do it only got stronger and stronger until it was all he could think about doing. It was like the multiverse's strongest aphrodisiac was being continuously pumped into him. He had a strong feeling that if all his urges kept getting more and more intense like this one was, that he'd be **** to act on his urges against his will no matter what the risk might be.

"Well John, it's not like you'd actually take this prank that far, but to be honest I doubt I'd have any choice but to believe you if you actually masturbated and jizzed in front of us," said Kate.

At that moment John's desire to be seen masturbating by Megan and Kate multiplied exponential. The amount he wanted to do it all of a sudden skyrocketed through the roof for some reason. He could no longer resist, exposing and embarrassing himself in front of the two girls was all he could think about. It was almost as if nothing else mattered to him. He didn't care anymore if they found out he was an exhibitionist, he didn't care if they would know from now on he'd been sneaking out of the house in the nude every night to go for a walk around the neighborhood. He no longer cared about how they saw him, all that mattered was that he had the time of his life while they watch him masturbate.

John immediately laid down in a comfortable position, his 8 in. huge morning wood was coated in so much precum that John's cock was glistening from the light reflecting off of it.

"See Megan, I told you he wasn't going to do anything, look he's going back to sleep in resignati—" Kate started to say before stopping when he saw what her brother was doing.

Kate stared at John with a shocked expression on her face, she was completely unable to believe her eyes. No sooner than she had opened her mouth, had John begun to slowly stroke his erect cock.

"Umm... I feel kind of uncomfortable, I think I'm gonna go into the kitchen and finally and get some breakfast," said Megan, turning around to leave the room after watch John jerk off for about a minute.

"No!!! Don't go!!!" shouted John, causing Megan to stop in her tracks, as he continued to jerk off right in front of the two girls.

"Why not, you seem kinda busy at the moment," said Megan uncomfortably. "I thought I'd give you some privacy, plus you don't seem yourself today."

"No! Please don't go Megan! Please don't!" begged John starting to increase the pace of his stroking a little, and occasionally letting out a quiet moan as he jerked off. "I want you to watch me, I want you to watch me more than anyone Megan. It aroused me so incredibly much to know that you of all people can see me naked doing something so lewd and perverted!"

Kate was still in a state of shock, she couldn't believe what she was hearing her brother say, she couldn't believe what she was seeing him do. "Could my brother actually secretly be a huge exhibitionist?" she thought as she watched him masturbate.

Megan decided to stay and watch despite how uncomfortable this situation initially made her (mostly because Kate suggested she do so). She didn't think John was in his right mind. However if Kate insisted she stay and as long as it didn't seem to bother John that she was there and watching him masturbate at the moment, she supposed it was alright to stay.

Megan was already blushing from when John confessed he wanted her to watch him masturbate more than anyone else, but she definitely wasn't prepared to blush as hard as she did when she heard the words he said next.

"Yes! Yes! Yes! Fuck me harder!" moaned John as he began jerking off faster and faster, eyes closed clearly lost in a fantasy. "Yes Megan! Yes! Fuck me in the nude where all these people can see us! Yes Megan! Yes! Keep letting me fuck your holes Megan! Let me use you like the cum dumpster you are right in front of all these people! I'm gonna fill you so full of cum Megan that you'll be leaking cum from every hole in your body for days to come. And when I'm finally done pumping you full of my hot sticky seed Megan, I'm gonna ejaculate so many fucking times all over your naked body that you'll be painted white in my hot sticky cum from head to toe."

With every word that came out of John's mouth just then, Megan's faced blushed more and more until her face was practically burning with humiliation.

Kate couldn't believe the vulgar, lewd, inappropriate words her brother was saying. Was the object of John's lustful fantasies really her best friend Megan? The same Megan who slept over the house last night. The same Megan who was watching him masturbate while he was completely naked.

"Megan I love you so much, continue fucking me in this public area as everybody watches! I'm gonna fill you up with and cover you in so much cum that it could have filled an Olympic swimming pool," moaned John in ecstasy. "I love you so much Megan, I love you! I love you! I love you! I love you! Fuck me harder! Fuck me harder Megan!" John moaned loudly, gasping for air as he jerked off even faster.

Kate and Megan watched John furiously masturbate in front of them. "he's gotta be close to cumming by this point, breakfast is gonna be ready soon, plus just look at him, he's experiencing pure euphoria."

"Yes! Yes! Yes! Oh fuck yes! Just like that Megan! Fuck you're such a good little cum dump," John moaned loudly. "It's time for me to fill your womb Megan! You're gonna have my baby! I'm going to impregnate you right here in front of all these people! Let me cum in you! Let me fill you up with my seed you slut!"

Megan and Kate watched as John jerked off at full speed. The whole time John was masturbating Megan's face was unbelievably red.

"I'm gonna impregnate you with my cum now you slut! 3! 2! 1! I'm cumming!" shouted John just quiet enough to not be heard from the house's living room. And, as he shouted that John's erect cock practically erupted spraying out multiple spurts of cum into the air, landing on the bed, on his naked body, on the bedroom floor and just barely managing not to land on Megan or Kate.

"Megan! Have my baby! I'm filling you up so you can have my baby!" John moaned in ecstasy. "Oh my god! I'm impregnating a girl completely naked in public with tons of people watching! Have my baby Megan you slut!"

John involuntarily thrust his crotch into the air as he ejaculated spurt after spurt of semen, mirroring the actions happening in him fantasy. When he was finally finished he collapsed on the bed in a post orgasmic euphoria. "Thank you so much Megan, after this I'm gonna cover you from head to toe in my sticky white semen" moaned John.

"I think the curse may have scaled the amount of semen I produce according to how horny I am." thought John.

Kate and Megan looked stunned by the time he finished, he had to have came at least 250ml of jizz. "Wow!" said Kate. "You weren't joking after all, I think Megan and I are gonna go now, Mom should be just about finished making breakfast."

"Yeah we should go," said Megan, staring at the floor, red faced, and mortified.

And at that the two girls left the room whispering back and forth between each other about what just happened.

When John finally came to his senses and could think think clearly his eyes nearly popped out of him head, his face turned even redder than Megan's was just now, and he had a horrified expression on his face.

"Oh my god! What the fuck did I just do and reveal to them!" thought John absolutely mortified. "My life is over!"
