Marcus places a flower on the table, given the importance introducing the lust protein into the environment he needs to see how plants are affected. He then prepares a vial of the goo, making sure to not let any of it get on him. Even letting a little bit of it get on him would be enough to expose him to the protein and begin the transformation. As much as he would love to become a creature of sex and lust it still has not been tested on humans so he doesn't know what will happen to him, so a simple flower will have to do. Mixing the goo with water to make it easier for him to apply it to the flower, Marcus pored the mixture on to the plant before siting back in his char waiting for any changes to begin.
A few hours go by with no change when the flower begins to wilt and lose its color. At first he just thinks it died, but he takes a closer look at the stem. It has started to throb and pulsate taking on a dark purple color, exited to see what's happening Marcus moves closer to get a beater look. the old leaves and flower falls off as the stem begins to grow getting darker as glowing white veins start to form. Large dark serrated leaves grow from the now 12" stem pulsing with the same glowing veins. At the tip a bud forms throbbing as it grows, heat begins to radiate from the changing plant. After a few minutes a sweet aroma fills the room and the bud opens reveling thick waxy red petals with a fleshy structure in the center that very closely resembles a human vagina dripping with purple nectar.
Marcus feels himself grow aroused not just from the appearance of the flower but also the sweet fragrance it's making. His pants begin to feel tight as he feels compelled to look deeply into the wet folds of the flower. Unable to resist the urge any longer he removes his pants freeing his rock hard member. He wraps his hand around his throbbing cock causing a shiver to run up his spine making pre cum drip from the glands. Marcus strokes his shaft quickly driving him close to orgasm as he moved faster and faster, his mind completely overwhelmed by lust. He falls to his knees as his body spasms, cum squirting from his dick covering the floor with his seed. Suddenly he felt himself become thirsty, once again he felt drawn to the flower the purple nectar dripping from the pussy like opening.
It looks so good.
