"Good girl," the succubus praises, as she slips away to the bed, lying down, though she gently tugs the elf along with her, using her tail. She seems quite pleased at how slowly and gently, yet eagerly, Ruby is teasing her, and Ruby can clearly see she's quite aroused, her nipples standing stiff, as soon as they're exposed to the air, and she squirms a little, as Ruby seems to find just the right places to tease her.
