A hard anal fucking with a hot sauce instead of lube. Up to your master if its a dildo or if he's willing to risk using his own condom covered cock.

An entire weekend blindfolded, gagged, bound in position to be fucked, earplugged, and wearing headphones playing a soundtrack or recording of your master's choice. Meanwhile you get fucked with no warning and no way of knowing if your master invited others to join or who they might be. And you don't get told afterwards. Master needs to make sure you get enough food and water and avoid bedsores in the process though.

Severe findom.

Master fucks somebody else on top of you, just using you as a piece of furniture.

Install a camera in your room to stream to your master 24/7

Since this is "no limits", break your chastity limit: you go in a chastity cage and he keeps the key.

Look into moving in with him.
