Decide to go down the way with leaks and gases
You cover themselves avoiding breathing rare gases, and covering themselves with their t-shirts so that the leaks do not fall on them, they also try to avoid these.
They go halfway, but forgot, the small puddles on the floor, they come into contact with their legs little by little, without realizing it they begin to change color and lower their density, becoming more gelatinous.
Only when their pants fall, being meters away from going out, do they realize, they see their bare and feminine legs, scared they think about doing something, but this only accelerates the process and without covering themselves now, they come into more contact and in seconds instead out of 2 guys, there's a pink and a blue slimegirl.
Suddenly they lose control of their bodies, and their legs melt, scared, they both hold hands, wanting to give themselves confidence and not lose themselves mentally, melting with the environment.
It seems to work, but the sensation of their bodies melting, mixing with each other, excites them a lot, and they decide to start playing with each other, wanting to enjoy this to the fullest, and stay here a while longer.
