Caius moved the hand he still had on Arlette's waist to her thighs. He slid into the slit at the side of her gown and pushed aside the silky material to touch her skin directly. He felt around it, let his fingers graze across the smoothness before he lifted the leg against his side.
Arlette took that action even further by hiking her leg up his body a bit more until she was wrapping around his waist. Or at least she tried to wrap around his waist but was blocked by the door behind them.
With her teeth still grazing against his skin, she stretched one hand toward the door and unlocked it so it slid open.
"Hmph!" she let out when she realized the door had been their support to remain upright. She had pushed against Caius so much and had forced him to lean against it, so once the door was gone, they fell to the ground.
