Add Bisexual, and fed by sexual fluids only before confidently locking in

You frantically tap through the app interface, looking for more customization options as the countdown timer continues its relentless pace. Under the "Sexuality" tab, you slide the marker from "Straight" past "Curious" and all the way to "Bisexual."

"Ooh, playing both fields?" Becky giggles, her animated eyes widening with delight. "Doubling your options, smart thinking!"

Next, you search through the "Dietary Preferences" menu, scrolling past various options until you find a section labeled "Alternative Nutrition." There, nestled between "Photosynthesis" and "Blood Dependency," you tap on "Sexual Fluid Sustenance" and toggle it on.

"Wow, thirsty much?" Becky fans herself dramatically, her enormous breasts jiggling with the motion. "That's going to make dinner dates super interesting! Hope you like protein shakes, hun!" She winks lasciviously, making an obscene gesture with her hand and mouth.

The 3D model in the center of the screen updates, a subtle shimmer passing over its form. The succubus now seems to radiate an even more intense sexual energy, her glowing amber eyes somehow hungrier, her forked tongue occasionally flicking out between plump lips.

"Ten seconds left, babe!" Becky announces, her voice rising with excitement. "Going to lock in this little demon slut or what?"

Without hesitation, you reach forward and press the pulsing pink "LOCK IN" button. It depresses with a satisfying click, then begins to glow blindingly bright.

"Oh my god, yes!" Becky squeals, clapping her hands together. "Transformation sequence initiated!"

The phone suddenly grows hot in your hands—almost burning hot—forcing you to drop it. It clatters to the floor, screen still blazing with pink light that begins to project upward, filling the room with a strange luminescence.

An intense wave of heat rushes through your body, starting at your fingertips and racing up your arms. Your vision blurs as dizziness overwhelms you, sending you stumbling backward until your legs hit the bed and you collapse onto it.

"What's happening?" you gasp, your voice already sounding higher, softer somehow.

"Only exactly what you asked for, silly!" Becky's voice seems to come from everywhere at once. "You designed your perfect girlfriend... and now you're becoming her!"

Panic seizes you as the realization hits, but it's quickly drowned by overwhelming sensation. Your skin tingles all over, feeling as if it's being pulled and stretched in a thousand directions at once. A sharp pain erupts at the top of your head, and you reach up to feel something hard and smooth pushing through your scalp—horns, growing longer by the second.

The bedroom door suddenly opens, and David steps in mid-sentence: "Hey, have you seen my—" He freezes, mouth hanging open as he witnesses your transformation in progress.

You try to speak, to explain, but all that emerges is a moan as your body continues its dramatic reshaping. Your chest burns as it expands outward, skin stretching to accommodate rapidly growing breasts. Between your legs, an impossible hollowing sensation makes you cry out in shock and confused pleasure.

"What the fuck?" David whispers, unable to look away as wings burst from your shoulder blades in a spray of pink sparkles rather than blood, leathery and bat-like just as you designed.

The transformation continues relentlessly, your waist cinching inward while your hips flare outward. Your feet elongate painfully, toes fusing as they transform into sleek black hooves. Every change sends conflicting signals of agony and ecstasy through your nervous system.

David remains frozen in the doorway, witnessing the entire process from start to finish as your body completes its metamorphosis into the succubus seductress you so carefully designed.
