Cockring for Chad

"Bro, bro! I've got one!" Chad yelled, waving around a cockring as he waddled down the hall. Mike looked over at his girlfriend, Vanessa and they rolled their eyes at each other. They had heard about these things from a friend who worked in a lab that dealt with alien tech. The friend swore it was legit, but he also had a habit of exaggerating stories. Still, it was an interesting concept. The ring was supposed to give you the virility of a Martian and make you irresistible to both men and women. Of course, given it was Martian tech there was a valid concern that it would eventually turn the user into another slutty female for them to breed.

"Seriously?", Vanessa asked. "You've heard the rumors of Martian tech. There's always a catch. Sure, you'll get laid but I bet soon enough it'll be your own pussy getting railed. I'm not sharing Mike with you if that happens."

"Fuck off that shit isn't real. I'm trying it," Chad said, lifting up his gut so he could slide the ring on. There was a moment of resistance, as if the ring didn't want to be put on him, but then it slipped into place. Suddenly, a hum emanated from the ring and a warmth spread through Chad's body as fat melted away, instantly going from obese to slightly chubby. Vanessa gasped, her eyes locked onto Chad's newly body.

Chad flexed his arms, grinning widely. "Feels amazing!" he exclaimed. As if to demonstrate his newfound virility, he grabbed Vanessa by the waist and lifted her up, pressing her against the wall. Her eyes were wide with surprise, and she could feel his erection pushing against her leg.

Mike watched in disbelief as his best friend grabbed his girlfriend. He had never seen Chad like this, so confident and dominant. He found himself getting hard just watching them together. Mike hesitated, before demanding Chad get off his girlfriend.

"Just playing around. Lets hit the bar!" Chad cheered, giving a hip thrust.

At the bar, they met up with some friends and immediately began to party hard. Chad was the center of attention, flirting with both men and women alike. The ring seemed to be working wonders for him, as everyone wanted a piece of the transformed Chad. It wasn't long before Chad left with a buxom blonde. Mike and Vanessa hung around a bit longer with their friends to give Chad some time alone in the apartment and left several hours after Chad. To their surprise, they could still hear the couple fucking in Chad's room.

"Oh fuck. Oh fuck. Oh fuuuuuck I'm cumming again! Never stop fucking me!" came the cry from Chad's room.

"There's no way they've been at it for 2 whole hours, right?" Mike asked as he and Vanessa walked to his room. They could hear Trixie screaming her head off as she climaxed again and both of them were getting turned on listening to the show.

"After what I saw at the bar, I'll believe anything," Vanessa replied. "You need one of those cock rings too. In the mean time, get these pants off. I've been aching for this dick." She reached down and grabbed his cock through his pants. Mike groaned, unable to resist her touch.

" Fine, but you're learning to eat pussy if it turns out to be a Martian trap," Mike said as he leaned in for a deep, passionate kiss. They stumbled into his room and tore each other's clothes off, their lust fueled by the sounds of their roommate's endless fuck session. As Mike drove his cock deep inside her, they both couldn't help but wish they were experiencing the ecstasy in the other room.
