"My, my, maybe we should have gotten this mask on you sooner, foxie..."
Ren would have protested at the name, if he'd been in any position to do so. His cock jutted up obviously from his groin and he panted quietly as she wrapped her paw around it, her scaled skin slightly loose in evidence of her soon to come shedding. Stroking his length as if she had all the time in the world to enjoy and tease the comparatively helpless fox, Enora chuckled as he rocked his hips up from the bed. Digging his short claws into the bed, he fought not to react, grunting softly as he rocked up into her skilled paw.
And then her free paw was on the mask, cutting off his breath with a tap of the button.
The fox lunged for it, eyes bulging as his body reacted in the only way instinct knew how: find a way to breathe. Whimpering and gasping, he clawed for the mask, suddenly desperate even as his shaft throbbed, pre-cum drooling copiously from the tip.
"Uh-uh," Enora said, grabbing his paws as he reached for the mask. "Don't make me tie you up, Ren, you gotta be good and not fight it."
Ren's eyes watered within the mask, lips parted in a muted howl that could not be spent without the luxury of breath. He wrenched his paws free of hers, fumbling for the straps that closed the hood around his neck, panic taking over the erotic edge pulsing through his body. Tongue slapping wetly against the side of her muzzle, the snake grumbled her disapproval. Perhaps she would have shown greater concern for her boyfriend if his cock had not been still hard in her paw, evidencing his desire even as he struggled to slip completely into the right frame of mind to enjoy the attention.
Enora rubbed the top of the hood, letting him feel her touch through the latex.
"Fine then, Ren, we'll play it that way. Throw your head all the way back so I can see if you want to stop, okay? I don't have the squeaker today for you to hang on to."
Flicking open the breathing holes again, Enora quickly grabbed a length of rope -- Ren really was one for just leaving bits lying around all over the place -- and slipped it around his paws. She forced his torso up from the bed by wedging her knee into the small of his back, making quick work of tying up his paws. Able to breathe again, Ren did not protest, dragging in gulps of air while he knew he had the ability to. He did not make the sign that they'd agreed would call an end to any fun that otherwise rendered him mute.
"Good fox," she breathed, pumping his cock once more with his paws bound and ready. "I know you'll enjoy this."
Ren wouldn't have disagreed even if he'd had the voice to be able to. As she stroked his length, he anticipated the rise of her paw to the mask with a tingle that ran through his whole body, fur standing on end across the back of his neck. He pulled against the bonds around his paws, but there was nothing he could do -- or really wanted to do -- to stop Enora from shutting the breathing holes once more and rendering his world one of gasping once more.
Twisting and writhing within the limits of his movement, Ren's chest heaved for breath that he simply could not drag into his lungs. Dimly, he kept himself aware of keeping his chin tucked down close to his chest, afraid to have the restraining ecstasy cut off by their accidental safety signal if he lifted his head up too rapidly.
And, all too quickly, he could breathe again, gasping for breath as his head spun. Enora's paw still moved on his cock, slick with the amount of pre-cum spilling forth, and he yipped, bucking up into her paw in a wordless beg for more.
Pleasure washed over him as her paw picked up the pace, masturbating him as if she was trying to get him off straight away, but then she shut off his air again and his world rocketed into air deprived ecstasy. His muzzle pressed into the side of the mask, unable to even pin his ears back as the rope cut into his wrists. She held him without air for longer than before, drawing out the moments of air loss until his vision swayed, cock throbbing with such need that he could have ejaculated right there and then.
Balanced on the precipice of climax, Ren came back slowly, only aware that he was able to breathe after he'd inhaled several times already. Dragging the tips of her fingers up his length, Enora lazily circled his cock-head as the fox squirmed for release.
"Are you close?"
Ren nodded quickly, electric feeling racing through his nervous system. That was all the notice Enora needed to send him spiralling over the edge. Without allowing him time to completely regain his breath and senses, his ability to breathe was cut off for a final time and there was no going back from the cliff-edge of orgasm. Ren tried to howl and failed, pain searing through his lungs as she pumped his length for all she was worth, skin pulling back and forth with the rise and fall of her paw. His vision greyed out within the dark of the mask, eyes rolling into the back of his head, and then the fox's mind fell prey to the whims of his body.
He could not make a sound as he climaxed, but his cock spurted, a thick rope of cum jetting up over his stomach. He felt it splash down into his own fur, but Enora kept him gasping until the last drool had trickled from his shaft and his lungs burned for oxygen. On the edge of blacking out with that faint hint of nausea pricking on the outskirts of his senses, Ren finally found himself able to breath, drawing in lungful after lungful to soothe his burning lungs.
It had been worth it though, oh so very much.
Stroking his side gently, running her fingertips through his fur, Enora murmured to him as she slowly unbuckled the mask, allowing him out of the headspace one strap and zip at a time.
"We'll have to use this mask again, kit..."
