Stacey gives her some new lips (and more)

In a stupor of absolute satisfaction you finally felt the need for rest come over you. Looking out the window you realized it's well into evening. You climbed onto the couch.

"Rest, my pets," you muttered before drifting off.

Your eyes fluttered closed...

You felt yourself slipping out of an erotic, tempestuous dream to the pleasurable sensation of lips around your cock.

You moaned and blearily blinked open your eyes to look down at Stacey sucking your cock.

Wait, no, that wasn't Stacey. It was someone unfamiliar, wearing one of Stacey's tops, a tight sleeveless shirt that looked good even on a flat chest. Wait. A flat chest.

"Krissi?" you moaned, still coming to full awareness.

The cocksucker met your eyes, looking up, and you saw that yes, this was Krissi. But changed further. Her face had softened further, becoming fully feminine though without makeup. And her lips were a lush, swollen pink. Looking at them you just knew in your gut that they were made to wrap around cocks, that her mouth's true purpose was to serve as a repository for cum. The sense was so strong that you dimly realized it must be the influence of the marker.

That didn't matter though, she was bringing you to a peak of pleasure even faster than Stacey could, bobbing and licking and deepthroating your cock with an intense focus and rhythm every movement designed to maximize the pleasurable friction you felt.

Before you even realized it you were cumming in her mouth. Krissi moaned as your seed filled her mouth, then after a few long seconds sat back and tilted her head to the ceiling in glass-eyed rapture. Cum dribbled from her mouth down her chin and onto her chest.

"I'd call that a good test run."

Abruptly you realized Stacey was there too, watching the show from behind.

"What did you do?" you asked.

She grinned and went to the still-dazed Krissi and pulled up the tight top. On her upper belly were the new inscriptions:
