Nancy's eyes were already glazed over. She couldn't control her panting and soft moans, yet she struggled to maintain some rationality, trying to prevent her brother-in-law from taking further liberties.
"Big sister, your legs are so beautiful. Let me rub against them."
"I promise I won't put it inside!"
Luis said lasciviously, licking her neck, then adjusted her pliant body into position.
