While Mikey has always been the kinkiest, Donnie has always been the most experimental. He’s willing to try anything, really, and that's what excites Leo the most. If he wanted to do something new, and do it safely, all he had to do was approach the genius with his desire and his wish would be granted.
So when Leo read about someone being obsessed with sensory deprivation, he knew he had to try it immediately, and he knew who he had to go to in order to get the best experience possible.
All he had to do was introduce the concept to Donnie. Not long after, Leo is bent over a table, his limbs tied to the legs of it and his mask turned on his face so he could no longer see. Donnie had gone the extra mile and put sound blocking headphones over the slits of his ears, and although he could still hear it was very muffled.
It was hard, doing this, giving Donnie his vulnerability. His mind had trained himself to always be vigilant, to always be prepared for anything and everything. With his control stripped, he didn’t feel like Leo anymore. But with Donnie...it was undeniably different. He felt safe.
Something cold touches his tail and he jumps. The ball gag in his mouth prevents him from saying anything. It trails down, leaving a wet chill on his skin in its path. And then it’s pressing directly at his entrance, pushing until it’s inside of him. Leo whines, the feeling of his insides freezing causing an electrifying sensation to spike through him.
There’s heat on his buttox- a hand, his brain supplies. It gropes and carrases in a soothing manner. The juxtaposition between the heat and the cold is dizzying. And best of all, it’s intensified in a delicious manner.
The cold, hard object in his ass liquifies at an alarmingly quick rate. It’s ice, he realizes. Donnie put ice in his ass. The melted ice drips down his thighs and he can feel every stream as it slides down into the crease of his knees. Drool begins to build up in the corners of his mouth, and it continues to grow as Donnie puts more ice into his ass.
There’s pressure on his marginal scutes, pulling him backwards until his bindings catch and Anxiety him from moving ever forward. Leo tenses, his eyes darting beneath his mask. Nervousness and excitement coils, the unexpectedness and unpreparedness only intensifying those emotions.
And then, all at once, he’s full. Achingly so, overwhelmingly so. The fullness pulls back and slams back in, over and over again. He feels more than hears the squeak of the table from the sheer force of Donnie’s thrusts. The sensation of everything is just so overwhelming, he can’t help but cry.
His dick, which has been hanging over the edge of the table, twitches violently. He’s going to cum without even being touched, he realizes. That’s never happened to him before. Can he even do it? Or, he supposes the bigger question here is will Donnie let him? It doesn’t take long for him to get his answer, because Donnie slams forward one last time and floods his insides with boiling liquid.
It pulses directly against that special spot inside him and that’s all it takes for Leo to burst. It causes him to scream. He can hear it through the headphones, and he figures that everyone in the sewers probably knows what he’s up to by now. The orgasm drags on for what seems to be forever, washing through his whole body and making the tips of his toes tingle.
Leo doesn’t remember blacking out, but when he wakes up he’s cradled in Donnie’s lap, a blanket wrapped tightly around him. HIs mask is adjusted properly and the ballgag has been removed, leaving a numbness and ache in his jaw. On top of that, his backside is sore to the point where he knows he’ll be walking around with a limp. That’s a thought for later, though, so instead of dwelling on it he churrs and nuzzles deeper into Donnie’s comforting warmth.
“Thank you…” He mumbles.
Donnie smiles and kisses the top of his head.
“Anything for you.”
