Lena slammed the book shut but kept her fingers buried in her cunt. The werewolf smut had her soaked, pages describing a thick, veiny cock stretching a woman open while the beast's knot swelled inside her. She pumped two fingers deeper, thumb grinding her clit, imagining that exact stretch.
A low growl rattled her window. It slid open. A massive, furred figure climbed through, eight feet of muscle and teeth. His cock hung heavy, already half-hard and dripping.
"You've been calling me with those filthy books," he said, voice rough. "Time to live it."
He crossed the room in two strides and yanked her legs apart. No preamble. His tongue dragged up her slit, rough and hot, lapping at the mess she'd made. Lena moaned and grabbed his ears. He sucked her clit hard, then shoved his tongue inside her like he was already fucking her.
"Get on your knees," he ordered.
She dropped. His cock slapped her face, thick as her wrist. She opened wide and took the head, tongue swirling around the flared tip. He thrust, forcing more down her throat until she gagged. Spit ran down her chin onto her tits.
"Look at you, sucking wolf dick like the slut in your books."
He pulled out and flipped her onto the bed. One clawed hand pinned her wrists above her head. The other lined that massive cock up with her entrance. He pushed in slow at first, then slammed the rest with one hard thrust. Lena cried out, stretched to the limit.
He fucked her like an animal, hips snapping, balls slapping her ass. Each stroke bottomed out against her cervix. Her cunt clenched around him, already fluttering toward orgasm.
"Take it," he snarled. "Take every inch."
She came hard, cunt pulsing, juices squirting around his shaft. He didn't stop. He flipped her onto all fours and mounted her properly, one hand fisting her hair. His cock drove deeper at this angle. She could feel the base starting to swell.
The knot pressed against her entrance, thick and insistent. He pushed harder. It popped inside with a wet sound, stretching her wider than anything she'd ever taken. Locked together, he ground against her, short brutal thrusts that rubbed the knot over her G-spot.
Lena screamed into the mattress as another orgasm ripped through her. The werewolf howled, flooding her with hot cum. It pumped in heavy spurts, trapped by the knot, swelling her belly slightly.
He stayed knotted for long minutes, licking the sweat off her back while his cock kept twitching and filling her. When the knot finally shrank enough, he pulled out with a wet pop. Cum poured down her thighs.
He flipped her onto her back again. "We're not done. Those books have more scenes."
His cock was already hardening once more.

He pushed back inside her cum-slick cunt and started fucking her slower this time, deep and deliberate, making sure she felt every ridge. Lena wrapped her legs around his waist and met every thrust, lost in the raw stretch and the filthy sounds of their bodies slapping together.
By the time the sun rose, she was hoarse from screaming, covered in his cum, and already wondering which book she'd read next to call him back.
