It's a good thing he is removed from the party. It gotten him riled up. Lan Wangji pretends to ignore his teasing remark about that part of his body that requires his attention. Once he laid on his stomach, he opens the bottle of perfumed oil and rubs over his hands. It felt warm to touch and he pours the oil over his back and body.

"Try to relax." He said as he starts to slowly massage his back, his hands placed on his skin and start rubbing in circles to release the tension and stress over his body. "Yes, it's a massage oil..." He trails off, not telling him that it also doubles as a lubricant. The moment he starts rubbing the oil over his back and tender parts of his body, it starts to heat up upon contact.
