Trevor gently floats to the boy with the towel around his waist. The boy appears to be dozing too, his eyes closed he is breathing slowly inhaling the steam and letting his muscles relax in the heat.
Slowly Trevor places a rubbery hand on the front of the boys towel and gently lifts it away exposing the naked boy beneath it.
The boy grins a little, but keeps his eyes closed. So he is just pretending to be asleep. What a tease he is. Trevor pretends not to notice as well.
Gently he slides his hands down the boys chest, his smooth rubbery skin smooshing gently as he presses himself in to the boy, lower his head to the boys slowly hardening cock. He takes the boy in to his mouth, his soft rubbery mouth stretches to engulf the boys entire package.
The boys eyes open a little as he gasps, feeling the rubber stretching over him is a sensation he wasnt expecting. It feels better than anything he has known before as Trevor explores him with his balloon body.
Trevor moves his mouth around and stimulates the boy who jerks a little with pleasure, then he feels the boys hands on his inflated head pushing him away. The boy must have noticed that a giant man shaped balloon is doing this. The boy gasps a little. He is indeed afraid of what this balloon is doing but he also enjoys the feeling.
Trevor resists and holds on tighter. He grips the boys hands with his own and finds that his strength isnt very great, since he is but a balloon. The boy struggles, but is unable to break free as Trevor continues to suck on the boy.
The boy reaches climax and moans as Trevor feels something warm enter him, and then vanish. Something odd is happening.
