She is relaxing some, perhaps leaning back, her legs a bit apart. He is kneeling, arms bound behind his back, head buried in her crotch. He's pleasuring her with his tongue whether or not you can see that much detail. But it's not just another image of cunnilingus, nor even of cunnilingus with bondage. She's in real control, for there are a couple additions that look they came from a bicycle. See, his legs apart as well, so you can see some of the special hardware he's bound down into.

At her hands are the controls like one finds for bicycle brakes. Squeezing the handle or level pulls a cable. The cable, or rather cables, go to something like the usual bike brakes. One for each ball. The shape of the brake pad is different, customized to keep his balls properly trapped in the jaws of the thing. If she squeezes one side, he feels it. If she squeezes the other side, he feels it. She can guide him to (or perhaps away) and get her point across with ease - and if she should lose herself in pleasure and squeeze both controls hard.... well, it's all about her pleasure, not his.
