A pink and blue X-Change pill

You see Mira pop something in her mouth quickly but you only catch a glimpse of it before she forces you head back down into the bed and you close your eyes to protect them.

You whimper as her hand enters you again, but soon something new is poking between your legs

"What is that?" you ask, awakening from your bliss, the worry evident in your voice.

Turning around as much as you could to face Mira, a smiling something strange come into your view.

It's Mira but the lower half of her body is different replaced by something massive

"My cock," she answered simply. "You think you're the only one that uses X-Change pills? One of us has to wear to dick here and I don't feel like changing all the way just for you."

Before you could say anything else, Mira's new cock head slipped into your pussy.

"Fuck you're tight."

Your eyes widened as the cock slipped deeper into you.

"No! No— oh my god!" your protests quickly turning into moans.

Yet again, you were experiencing the best feeling of your life as Mira's big, warm, cock slid into you, spreading you apart.

"Miraaa," you moaned.

"You feel so fucking good," Mira groaned. "Tightest pussy I've ever fucked."

Your heart swelled with an odd sense of pride, and, lifting your hips, you pushed back onto Mira's cock.

Starting to thrust in and out of you, Mira laughed.

"You love this, don't you? Look at you, you can't deny it. Tell me how much you love it."

"I love it—" you gasp. "I love it so much I don't wanna— I don't wanna change back. I— I love it."

Trying to match Mira's rhythm, you pushed back when Mira pushed in.

"You're a little slut, taking eight inches of your sister's dick, begging for it, burying it in you," Mira stated, her skin slapping against yours. "Who's pussy is this?"

"You, it belongs to you!" you practically scream, your hands clenching the sheets in pleasure. "It's yours. Oh god! Fuck me Mira!"

"That's right, and this is your cock now," Mira responds, giving you hard, pointed, thrusts. "We'll take— care of each other— fuck each other— when we get horny."

Mira stops and lifts you from the bed, setting your feet on the ground before she lay back on the bed.

"Your turn to do the work."

Eagerly, you climb atop of Mira, straddling her male body. You grabbed her dick, wet with your juices, and guided it back into your pussy, lowering yourself down all the way.

Your hands find Mira's chest grasping her breasts, and you lean over pressing your own new tits into hers, lifting your hips and slamming them back down. You awkwardly try to gyrate your hips like in some of the porn you've seen but quickly gave up.

"Bet you never thought you'd see a pussy being fucked from this angle?"

You bite your lip and shake you head. Despite all the curiosity you had of changing into a girl, and all the time you spent thinking about it, having a dick inside you had never been a thing more than a distant passing thought.

Looking down, you watch as your small breasts bounce and jiggle as you bounce on Mira's cock. You remove your hands from Mira's tits and place them on your's, grabbing your boobs and groping them roughly.

Mira's hands grab your waist, almost wrapping completely around, and she starts to thrust up.

"This might be better than sex as a girl. I love fucking your pussy, 'Leah'"

You throw your head back in pleasure. This was your first time having sex as a girl or boy, but you were having a hard time imagining how anything could be better.

With a few more thrusts, your body shook, experiencing yet another orgasm on the day.

Still high on your bliss and urgent thought enters your mind. You feel Mira start to thrust faster and her dick throb. Having had a dick for your whole life you know what comes next
