This is the second story in the Butterfly House series. If you missed it be sure to read the first story in the series called Cum Sponge.
It had been a week since MJ's ordeal as a cum sponge. Her jaw was still sore and, to be honest, she wasn't sure how she survived. Having Grayson's dick lodged in her throat for extended periods of time almost suffocated her to death. But, she made it. Greyson was in a constant state of bliss the whole time, almost oblivious to her suffering. Still, she couldn't be too mad; she had agreed to the situation and willingly participated. No, being mad was not an option. But getting even, oh yes, getting even would be so much more fun.
Over the past two week they had been exploring this coastal mansion they bought sight unseen and had learned a few things about the previous owner. Apparently he was a genius inventor with a fetish for BDSM and had this home custom built over the years with hidden rooms, passageways, and secret compartments throughout the house all filled with his crazy inventions.
"Hey Honey, look what new invention I just found." MJ offered the little box to Greyson.
"Ohhh, a new one. Is this one for you or for me?" Replied Greyson.
It seemed like they discovered another invention everyday. The previous owner was a prolific genius.
"This one's for both of us. But it goes on you." MJ smiled.
Greyson took the box and opened it. Inside was a simple black band a little larger than a finger ring.
"A cock ring?" Greyson questioned. "What special powers does this endow?"
"Oh yes, special powers is right. This one can control pretty much everything about your cock: arousal, erection, length, girth, sensitivity, pain, and orgasm. There's even an app. Check it out." She handed him her phone.
"Wow! This is incredible." He said as he fingered through the app playing with the sliders and toggles. "Shit! This looks like it could give orgasms at the touch of a button." He exclaimed. "Can I try it on?"
When they first arrived and starting finding inventions they had made an agreement that whoever finds the invention gets to be in charge of it.
"Sure, but, I think it's only fair that you agree to wear it for at least 48 hours. And since it's mine, only I get to touch the controls." MJ lifted and eyebrow and smiled.
"Ohh, I can tell I'll be in for it with that look. But how can I say no to the possibilities. But before I agree to 48 hours, I need a test. I want to try it on and try that instant orgasm. If it's good, then you can have your 48 hours."
"Sure, that seems fair." MJ nodded her head in agreement.
Greyson picked up the ring and slid it down to the base of his semi-rigid cock. It was slightly stretchy, almost like a silicon ring, but way too big and hung loose.
"Are you ready for this?" MJ asked.
"Yep, let me have it."
MJ tapped a few buttons on her phone and the ring cinched tight around his cock. A few more taps and his cock went rock hard and bulging.
"Shit!" Greyson let out.
"Oh, that's interesting." Said MJ. "I only turned it up a couple of notches on the erection."
"Shit!" Greyson repeated. "I can't imagine how I could possibly be any harder. This is damn uncomfortable as it is. Let's try the orgasm button."
"Sure thing honey." MJ tapped a few more buttons.
"Arrggghhhh!" Greyson cried out as his cock began erupting. "Oh my fucking god! Fuck! Fuck! Fuck!" His orgasm kept going and going and wave after wave of pleasure washed over him.
"Oh, I love this device!" Shouted MJ as she kept tapping the orgasm button.
"Fuck! Fuck! Ohhhhhhhhh!" Greyson started to mumble and shake as his cock continued to orgasm and his body convulsed in pleasure until MJ finally stopped pressing the button.
Greyson lay on the couch panting cum sprayed all over himself and the couch.
"Damn! That thing is incredible. You can put that ring on me for as long as you want, forget 48 hours."
"Are you sure about that?" MJ asked.
"Yes, oh yes! Do it for as long as you want. It's yours."
Through his post orgasm haze an image popped into his mind of MJ just a week ago with his cock embedded deep into her throat, her eyes wide with fear as she struggled to breathe and for a brief moment he had second thoughts.
Suddenly the band tightened around his cock even tighter. It pinched and was uncomfortable.
"What the." He gasped.
"Ohh baby, you have no idea what you just got yourself into. I'm am going to make you pay for what you did to me last week and I'm going to enjoy it the entire time.
Greyson hesitated for a moment then reached down to try to adjust the ring. The moment he grabbed it, an intense pain shot into his balls and he let out a yell and balled up in pain.
"No, no, no," MJ said as she wiggled her finger at him. "You can't take it off, adjust it, or even touch it. I'm in complete control now. And don't even think about trying to get the controls on my phone it's facial locked to me only.
Greyson lay on the couch still trying to catch his breath.
"Now, let's see what this thing can do."
She tapped a few buttons on the app and Greyson gasped again.
"There, I've turned up your erection another notch. It should be nice and uncomfortable now. I've also made it a little more sensitive. Every touch will feel like electricity to you driving you mad with a need to cum. Why don't you go ahead and jerk yourself off to another orgasm while I watch. I guarantee it's going to blow your mind."
Greyson, being already extremely turned on and eager for another orgasm, waisted no time and began stroking himself. His breathing quickly grew rapid and his eyes closed.
"Oh god, this is good. Oh fuck, I need to cum so bad! Fuck, fuck, I'm so close. Oh my god!" He kept pumping his cock hard and fast his breathing fast now and his whole body beginning to jerk and gyrate.
Harder and faster he kept jerking off.
"Oh god I need to cum!" He cried out desperately.
"Oh this is delicious." Said MJ as she slowly fingered herself. "I'm enjoying seeing you so aroused and desperate. You're making me so damn wet!"
Greyson continued jerking off and writhing around. Suddenly, he stopped and looked over at MJ.
"What? Why'd you stop?" She questioned in disappointment.
"I don't think I'm going to cum this way." He forced out. "But maybe if I fuck the shit out of you I will."
With that he rushed over to MJ and grabbed her arms pulling them away from her swollen pussy. He quickly and with the force of a mad man pushed her legs apart and plunged his cock into her.
"Fuck!" MJ grunted as his weight slammed into her.
