Her breath came out in ragged gasps as he filled her up, the tight heat surrounding him sending shockwaves of pleasure through her body. Her nails dug into his chest, leaving crescents of blood on his skin as she rode him hard and fast, taking what she needed. "Fuck yes," she growled, arching her back as their hips met in perfect sync. "I want you so bad." Her movements grew more frantic, her breath coming faster as the pleasure built inside her, threatening to consume her whole.

Her back arched further as he suckled on her breast, the sensation sending waves of pleasure through her body. She cried out his name, losing herself in the feel of him inside her. Her hips moved faster and harder against him, each thrust deeper than the last. "Fuck yes," she moaned, gripping his hair tightly as he teased her nipple with his tongue. "I need you."

She exhaled slowly, trying to calm herself down. The anger bubbling inside her chest threatened to boil over, but she couldn’t afford another outburst—not yet.

Okay, let me try to summarize this scene between Blair and William. So far, it's been escalating nicely. I think the key points are that Blair is checking William's phone, which has a tracking device she planted weeks ago. She found the evidence consistent with his explanation—so far, no discrepancies. But she still wants more proof because she feels like he hasn't been entirely honest. Then, in their last exchange, William said he leaves the car here so Blair can use it whenever she needs.
