You stalk towards the man, your ass swaying with each step, and shove your hand down the front of his pants to grasp his thick cock. He moans like a beast in heat when you squeeze, and you feel him twitch and harden. You will your magic flowing into the man's cock and it begins to grow, while the rest of his body starts to change. You aren’t sure exactly what you are doing, but it feels so natural you go with it. You watch as his body hair falls from him and his skin takes on the same waxiness as yours, changing from sun tanned brown to a beautiful green only a few shades lighter than your own.
With a loud rip his pants burst, as his ass balloons out the back and his now massive cock pushes from the front. Your eyes dart down to that big slab of meat in your hands and your mouth waters. You have never laid eyes on something you wanted more in your life.
Changes continue to ripple across his body like stones skipped across a pond. Ripping your eyes from that big delicious cock you find the rest of his lower half has become completely female. His calves are now shapely, and his thighs thick and inviting. You reach down and cup his heavy, hairy balls with your other hand and stroke his taint with the tips of your fingers as you start to jerk his cock and feel a wet slit forming as you do so. The man is breathing fast and hard as you stroke his cock faster. His moans suddenly turn high and breathy as his balls withdraw into his body. You find you are sad to see them go, as you slip a finger between his new folds.
His shoulders and chest, once big enough to shame a bull, rapidly dwindle. For a moment he almost looks like a young boy, before his pecs begin to swell again. Your own breath comes hard and fast now as tiny buds at appear, then larger and larger they swell until they're even bigger than your own impressive assets. His nipples have become as thick as your thumbs and tiny amber droplets bead from them. You can feel your juices dripping down your thigh. You've never been so turned on in your life. A strong, sweet scent like pungent flowers fills the air and you see the man’s eyes dilating as the heady aroma hits him.
The last thing to change is the man's face. It appears to flow like water for a moment before setting into a narrow, elfin-like face with pointed chin, dark green lips, large amber eyes and high cheek bones. His hair stays the same but turns bright red, the unruly mess combining with his delicate face to create an alien beauty. The man is clearly not human anymore. Nor can he rightly be called a man.
Well, except for one place. The new dryad's cock is as big as a horse's and hard as wood. You pull her down to the grass by her massive tool and guide her between your legs. A tiny voice in the back of your mind is screaming at you to stop. You're a man and a virgin at that, you can't let your first time be being split in two by this monster!
You scream in ecstasy and pain as her cock is thrust inside you, banishing the voice forever. The smell of flowers is everywhere.
