Flower

In the midst of the forest, an odd shadow cascades over your eyes. You glance up just in time to spot a star-shaped flower twirling down towards you. The vibrant blue petals are easy to make out from below and, oddly, don't match any of the foliage you see above. Wherever this flower came from, you step back in time to let it slowly drift down into your hands.
The iridescent topside of the petals shimmer beautifully, with the center glistening yellow and steadily oscillating like molten gold.
Would you like to smell its wondrous scent?

The flower can be randomly found when exploring the forest. You will sneeze if you smell it, causing a random change to your body, most often increasing the size of a body part.

No

Wary of strangely beautiful flowers that fall randomly from the sky, you decide to let it continue its path to the ground and head on your way.

Yes

It just looks so magnificent that you can't help but stuff your nose in and take a big whiff.
You immediately regret your impulsive inhaling, as an intense tingle erupts within your nose. You're nearly forced to laugh from the intense tickling sensation, but considering the area being affected, you instead halt your breath. Your next attempt to breath only intensifies the sensation further, your chest heaving to hold back. But, you're simply not strong enough…

All:

"ACHOO!" You sneeze loud and hard. So hard, in fact, that your butt balloons outward behind you, straining your pants. You also managed to annihilate the flower…
"ACHOO!" You sneeze loud and hard. So hard, in fact, that your hips stretch outward, becoming wider. You also managed to annihilate the flower…
"ACHOO!" You sneeze loud and hard. So hard, in fact, that your blood floods to your genitals, suddenly arousing you. You also managed to annihilate the flower…
"ACHOO!" You sneeze loud and hard. So hard, in fact, that you blast your semen into your pants, a sudden spontaneous ejaculation. You also managed to annihilate the flower…

The latter two will increase and decrease lust, respectively. Other variations may occur depending on your genitals:

"ACHOO!" You sneeze loud and hard. So hard, in fact, that your cock expands in your pants, nearly exploding through the fabric. You also managed to annihilate the flower…
"ACHOO!" You sneeze loud and hard. So hard, in fact, that your testicles swell between your thighs, making you hunch over your crotch for an instant. You also managed to annihilate the flower…
"ACHOO!" You sneeze loud and hard. So hard, in fact, that your vulva expands between your legs, squished between your thighs and making you walk awkwardly. You also managed to annihilate the flower…

Caught off guard and quite confused, you stumble off, wondering if there's a tissue nearby.
