Sloth

You look at the succubus and say the first one of the seven deadly sins that comes to your mind, "Sloth."

With your response the demon closes her eyes, unfurls her wings as far as she can and begins chanting in a language you don't understand and as she does, black smoke once again appears but this time it comes nowhere close to filling the room. It doesn't even surround the succubus, though the effects feel similar to the summoning of the succubus, they also seem significantly weaker. A tiny ball of smoke eventually comes together in her hand and when it cleared, a ring remained. A very plain, uninteresting, almost impossibly boring-looking gray ring. "Get one of your family members to put this on and then return to me, if you are still interested in this of course."

Saying that the demon turned her seduction back on, not as high as she could because she wanted you to be able to think. "Go along now. The sooner you leave, the sooner you can corrupt someone, return to me, and find out how hard I squirt so you can take a shower in my cum."
