You decide to take a walk around your local park, until you spot a woman that doesn't look human, but humanoid in shape, and get distracted by her bust, she notices this and bumps into you on purpose to trip, she steps over to you and moans, before saying

"Oh my God, are you okay?"

she asks in a taunting manner, before flopping on top of you.

"here, lemme help you up~"

she claims before you feel her shaking, and before you notice her slowly starting to get bigger...
