Pleasant morning

Vanessa woke up first the next morning laying on Mike's chest with his hard cock still inside her. Thinking it was the perfect way to start the day, she started gently riding his dick as she looked over his changes. Mike had always been in better shape than Chad and it looked like the ring's changes were more subtle. He looked....softer. He didn't have any morning scruff and the muscles in his arms had faded a bit. Somehow instead of alarming her, it made him seem all the hotter. She got to her knees and started riding him harder.

Mike grunted as he woke up to Vanessa bouncing on his cock, her breasts bobbing in his face. He reached up to grab them, squeezing them roughly before pinching her nipples. "Fuck, you look so good, babe," he growled, pulling her into a deep kiss as their hips met in rhythm.

As they continued to fuck, Mike couldn't help but notice how much more sensitive Vanessa seemed. Every touch sent shivers through her body and she was moaning louder than ever. She was so wet around his cock that he could feel her juices dripping down onto his balls. Mike grabbed her hips and started thrusting harder, determined to bring her to another orgasm.

"Oh fuck, I'm going to cum!" Vanessa cried out, her body tense as she came hard around Mike's cock. Her pussy clenched tightly, milking him for everything he had as she rode out the waves of pleasure. With one final thrust, Mike released himself inside her, his own orgasm hitting him like a tidal wave. As they collapsed together, sweaty and spent, Mike couldn't help but marvel at how amazing it felt to be inside Vanessa.

The rest of the week went by in a blur of passionate encounters and intense orgasms. Chad, Mike, Trixie and Vanessa found themselves unable to get enough of each other. Their bodies were constantly craving contact, and the Martian cockrings only seemed to fuel their desires. The changes wrought by the rings were subtle yet profound. The girls were more beautiful than ever, while the guys were looking more delicate but still incredibly hot to the girls. Both girls found their men enjoying having their nipples suck and teased and made sure to pay them special attention while they fucked.

As the days passed, they grew bolder, pushing the boundaries of their sexual explorations further and further. They experimented with new positions, toys, and even incorporated roleplay into their encounters. Each experience brought them closer together, deepening their bond and heightening their ardor.

One night, as they had one of their few breaks in the sex fest, Chad couldn't help but wonder if there were any downsides to using the Martian cockrings. "So, um, have you noticed any... side effects?" he asked tentatively as Trixie tweaked his swollen nipples and drew quite moans from him.

Vanessa smiled knowingly. "There are always side effects when it comes to alien tech," she said, running her fingers through Mike's longer hair. "But honestly, I can't imagine going back. I'm hotter than any bimbo we ever saw at the bar and I've been fucked senseless every night this week."

Mike chuckled, nuzzling her neck. "Yeah, I can't argue with that. I don't think we're turning into women or anything. We just feel better, sexier, more desirable." He looked over at Chad, who was still a little unsure. "Don't worry, man. As long as we have these rings on our cocks, we won't have to worry about getting bitched. Sure we've changed but our dicks haven't gone down all week. And besides, we get to be inside all these amazing girls all the time. What's not to love?"

Trixie chimed in, stroking Chad's chest. "And let's not forget how much fun it is watching you change right before our eyes. You're so beautiful now and I know how much you love when I rub my new tits against your nipples. Wouldn't it be nice if you had your own tits for me to play with?" She leaned forward and kissed him passionately, her tongue dancing with his.

Chad could feel himself growing more aroused by their words and actions. The idea of having breasts like Trixie's was incredibly hot, and he couldn't deny how good it felt when she played with his nipples. He knew there were risks involved, but as long as they stayed focused on enjoying each other's bodies, they could avoid any unwanted transformations.

They fell back into another round of passionate fucking, but something had changed. Whether it was voicing his fears or Trixie confessing to wanting to see more, Chad found his body becoming more feminine. He should be worried, but how can he when Trixie is so excited for his swelling chest and lavishes such attention on hid budding breasts?
