Third Wheel

As Gwen prepared to leave for your impromptu walk with her, you stared down at Cathy. You wanted to change her in some way before you left. You ran through a lot of ideas. So many options.

You focused on Cathy's face and Gwen's crotch and made a swap. Suddenly, Cathy's body limply slumped down into the couch as her face was replaced with your girlfriend's vagina. Your other body watched Gwen very closely. Something was stirring inside of her jeans as she was preparing to leave.

Geen unbuttoned her jeans and saw Cathy's eyes poke out from underneath. "Whoops. Sorry, Cathy. I didn't mean to shut you out like that. I always forget."

You felt like doubling over with laughter. The brunette you had swapped with earlier had said almost the exact same thing. Instead, you let out a stifled snicker.

"What's so funny, Sweeties?" Gwen asked.

"Oh, it's nothing," your Teenage Body responded. Looking down at her crotch, you asked another question in return. "Hey, Cathy. Don't you want to share your face with the world?" You wanted to know how your little swap had changed Cathy's perspective on life. Both physically and figuratively.

With one hand, Gwen pulled her panties away from her crotch so Cathy could speak while she used her other hand to continue rummaging through her stuff. "Not really. It's nice, warm, and cozy underneath Gwen's panties. Besides, it's not like other people can just walk around with their junk out. It wouldn't be fair to them."

You nodded along with Cathy. It was interesting how she was seeming to imply that Gwen could go out bottomless. But choose not to because clothes are more comfortable and to not make anybody jealous.

"Hey!" Your other body that was watching Cathy's body called out. "Do you want to take Miss Pussy-Face with us?"

"Nah, leave it. We'll have fun with it when we get back." Gwen gave your younger body a kiss on the cheek followed by a playful smirk. When Gwen was finally ready, the three of you with Cathy in tow left for your walk together.

"So, where are we going?" Gwen asked.
