We enter the scene as Master KindBond (the guy) is asking NanaYamiChan (the girl) if she is ready for trying As she confirms, he proceeds to put leather cuffs on her hands and feet, that matches her collar. With her on an inflatable bed, he then ties cuffs and her collar in a spreadeagle position. Such a beautiful sight she makes, so he takes a seat asking her to test her b*ndage. A few minutes of struggling later we got established that she is stuck with no way of escape.

For safety she gets a bell in her hand she can drop if too much. And with that extra safeword in place, they are ready to test her reaction to breath play!

First breath control thing to try is plastic wrap over face.

Second is plain old hands over mouth and nose.

For the third he goes out to get a tray of water and towels, and the part starts - using a spray bottle to make the towel more wet (blocking the air more). It goes on for quite a while, as he adds fondling and p*ssy spanking to the using her excitement from each to bring her higher.

Next is a ring gag and a loose blindfold - because he likes to dampen her sounds before he starts to tickle her feet!

Next is an evil crotch rope, pulling her butt up in the air while still tied spread eagle to the bed. To that he places a wet towel over her face again, and lets her struggle on her own for a while in her predicament. Sensing she is quite worked up, he brings her over the edge with a p*ssy spanking!

After calming down for a l*ttle (and loosening the crotch rope), it is time for another test: a plastic bag loosely over her head. She finds that if she pulls in her breath too fast it will stick to her face and stop the air, so she have to breathe very controlled. Extra hard as she cannot help m*sturbate herself against the crotch rope. After several minutes, he throws a wet towel on top of the plastic, making it even harder.

He then removes her gag, and they talk for a l*ttle while about how she experienced the breath control until now, and what she liked the most. We learn she have had practice on her own!

She is still excited and ready for more, so he replaces the crotch rope with a vibrator. Adding a wet towel over her head he again leaves her alone to enjoy her helplessness and body shaking *rgasms. After a while he comes in to do more breath control with his hands, then leaving her alone again with her face visible this time, as the vibrator continues doing its magic.

Finally, KindBond thinks she have had enough and stops the vibrator, and does a bit of aftercare and kissing (that turns into humping her a bit, before biting her p*ssy), and starts untying her legs.

She takes her legs up over her head to stretch them, but that looks like a new lovely b*ndage position to him, so he quickly ties her stuck like that, leaving her butt now open to a quick spanking. And her feet is sticking up, perfect for another tickling!

Satisfied that he has used her well enough for today, he finally unties her c*mpletely. Followed by a bit of aftercare and more talking about how she experienced the scene.

Full movie is 95 minutes, of which the main action is 75 minutes.

Note: This is not roleplay - it is a negotiated scene that both enjoy, during which they figure out which kind of breath play they prefer most. Other materials or scenarios might work differently and be more scary.

Girl in fun, spreadeagle tied to bed
