Unfortunately

When you wake up, you're no longer in your own mind. The pleasure has consumed you, and all rational thought is gone. Your hands quickly dart between your legs and return to masturbation, and some small piece of your prior consciousness examines the state of your body.

Your skin is now completely a light shade of green, with the exception of a few small locations. The skin of your lips, your nipples and surrounding areolae, and the walls of your labia are all a deep emerald color. All of your hair is gone, and in its place have grown small strands of cellulose, the same texture as a flower's stalk. A few flowers adorn your head, red and orange in color.

Thin vines snake around your body, sensitive to the touch and completely controllable via your thoughts. They especially encircle your arms and legs, swaying lightly even given a lack of breeze in the cavern. You've become slightly taller and thinner than before, likely totaling a height of close to six and a half feet, with much of the extra fat trimmed from your body. Your breasts and ass are slightly smaller as well, but it's hardly noticeable, and your body overall forms a pleasant hourglass shape.

Nothing but lust and arousal fills your mind. Your left hand focuses on your pussy, which no longer leaks liquid at all, while your right moves up to tweak a nipple. Seconds later, a small flow of liquid trickles from your breast, light brown in color, and when you taste it you not only feel an additional rush of arousal, but also recognize the sweet taste as sap.

Your mind lost, you do the only thing you know how to do, and masturbate. A lot. Future adventurers find you, still gripped in the throes of orgasm, and eventually one takes pity and offers to fuck you. One taste of your sap and they're trapped forever, similarly locked in orgasmic pleasure. Over time, you accumulate plenty of lovers, and the room becomes the location of an incredible orgy, one that no one ever escapes from.
