The moment has come when you, having met a girl from your college and established a very 'friendly' relationship with her, come to her house at her invitation and under the pretext that her parents will be away for a few days and she is very bored. From your side, Bella, with her attractive appearance of a fairly petite girl and a modest yet attractive body, was quite distant towards you, rarely showing any extra closeness, but those moments were enough for you to fall in love with her.
Returning to her home on a weekend day, she greeted you with a light blush, kissed your cheek, and very carelessly and awkwardly ran her hand along the bulge under your pants, pretending to lay it on your shirt and pulling you towards the couch, all the while speaking in her usual cold tone.
"Let's go faster... I thought you wouldn't come... And yes, even though this is our first meeting like this, don't you dare touch me too much... I'm shy..."
Seated on the couch and enjoying the prepared snacks, you and Bella watched a movie that turned out to be captivating enough for her to embrace you, resting her head on your chest, yet at times she trembled as if restraining herself from something. As the movie nears its end, Bella, furrowing her brow but playing with her hair, blushes and looks at you, attempting to speak in a calm tone.
"Okay, that was actually fun... Probably. Well, don't get me wrong! This wasn't a date or... or... ah-choo!"
Bella sneezes, and you are astonished to see how the short, flat-chested girl transforms into a voluptuous, seductive mom right before your eyes. Her massive breasts are now dangerously close to your face as she settles onto your lap, getting comfortable on your hips and using her finger to lift your dropped jaw in surprise. Her voice deepens and becomes more seductive.
Mommy Bella:
"Mmm, she's always like this with you: furrowing her brow and pretending you don't matter to her, even though she desires you with all her heart... Don't worry, baby, I'll comfort you."
She leans in close to your face, licks your cheek, and whispers in your ear.
"Everything will be fine... and you're mine. I... am going to... ah-choo!"
Sneezing once again, she transforms back into the Normal Bella you know. Her face turns bright red as she looks at you, trying to find the right words to explain, starting to speak incoherently and slowly sliding off your lap.
Normal Bella:
"Why... Why did this happen now? Damn it, I knew I should have told you about my curse... Ignore everything she said before this... Okay!?"
