Thief’s Ecstasy

You flood a creature’s mind and body with waves of intense sexual pleasure. The target must make a Wisdom saving throw. On a failed save, the creature takes 3d8 psychic damage and is charmed by you until the spell ends. While charmed in this way, the creature has disadvantage on Wisdom saving throws and you have advantage on attack rolls against it.

If the target has been pleasured by you (through sexual intimacy) within the last hour, it makes the initial saving throw with disadvantage.
