Conan O’Brien submitted himself to a professional dominatrix in Berlin during a hilariously NSFW segment, which aired on the Wednesday, December 7, episode of TBS’ Conan.

“Berlin has long been known as the place where people can explore their wildest and deepest sexual fantasies,” he explained at the start of the segment. “I wanted to find out if that’s really true.”

In the clip, which you can watch above, the late-night host, 53, role-plays with the sex professional — named Lady Velvet Steel, naturally — and acts as her pet puppy.

After the dominatrix, who claims to be an “expert” in the art of spanking, gives O’Brien’s bare butt a few smacks, she tells him to get on his knees. He obliges and Lady Velvet Steel asks him, “Would you like to be my little doggie?” to which he replies, “I’ll be your little doggie.”

She then puts a dog mask on O’Brien’s head and tells him to “wag [his] tail if [he’s] excited.” He responds by shaking his hips and saying, “Woof.” Next, Lady Velvet Steel puts the TV personality on a leash, walks him across the room while he’s on all fours and tells him, “Good dog.”

Prior to pretending to be Lady Velvet Steel’s pooch, O’Brien experienced other Fifty Shades of Grey–style moments. Not only did he endure the pain of nipple clamps, but he even wore a penis-shaped mouthpiece.
