Teri walked down a path when, out of a sudden, a pink magic circle full of symbols and diagrams lit up around her boot.
“Fuck, a trap!” she shouted and jumped away without hesitation, falling to the ground. A pink glow arose in the circle and flew straight to her, engulfing her entire body before she could avoid it. The light-show ended as quickly as it began and Teri stood up, cursing. But then she felt her dick beginning to throb, straining her outfit. A strange hornyness washed over her, only targeting that one genital.
“Hmmmm” she hummed, precum flowing from her already. Pants left her as she thought “A trap making people horny, why? Not that I'm against tending to my needs.” She put down her trousers, not caring about the coldness of the underground and began masturbating without a care.
After barely beginning to rub with both hands, she already came, cum flying from her and a strange heat enveloping her member. Her forgotten pussy joined in, its juices falling to the ground in driblets. Moans of pleasure echoed through the dungeons as she could feel something happening to her member. Every heartbeat it grew bigger by a inch, leaving her unsteady, before the weight forced her to the ground. A big puddle of cum formed in front of her, hiding the gray stone floor in a flood of white. She could only writhe as it blasted with full force, the output growing alongside it. That much nerve-ends sending elation to her mind was too much to bear, her eyes glazing over as she became a drooling mess and her brain experienced a sex-overload.
Her body sat limp on her member, even as the last of her cum dribbled out of her. Deep breaths left the little girl as she needed a pause.
Eventually her senses came back and she opened up her eyes. She was taken aback by the sight in front of her. Her dick was bigger than her height now, several feet pining her to the ground. Its girth was comparable to a tree now and still hard, begging for her attention. She almost began again stroking it again, but was held back the realization that it can grow again when she did that. The whole tunnel she was in could break in, as a turn was not that far ahead.
She began thinking about what to do with it.
