It was always a thrill sneaking in through Sidney's window at night, Billy Loomis mused as he climbed the tree that led to her room. His girlfriend's parents left for business trips often (rather, her dad did…everyone in Woodsboro knows what her mom really did whenever she left the house), but he found it more exciting when they were home and only a few rooms away whenever he stepped into Sidney's room for a little late-night loving.

Tonight, though…tonight his body thrummed in excitement. He was already hot and bothered, completely turned on from how Sid sat on his lap earlier in school, her ass unintentionally but oh so deliciously grinding against his cock. He just wanted to take her right then and there, to hell with public indecency and the stares they would get from the student body. In fact, it made his cock harder to think about their classmates watching him claim what was his.

But tonight…

Tonight he climbed through the open window to see Sidney sleeping peacefully in her bed, ready for him.

They were trying out another new kink called somnophilia. Somnophilia, particularly consensual somnophilia, is the act of having sex while one partner is asleep and utterly unaware of the other partner's actions. This kind of kink, though, could go sideways if handled incorrectly, so he made sure to obtain Sidney's consent beforehand, which she readily gave.

'My dirty girl,' he thought with a smile, remembering how eager she was when he brought up the subject. His beautiful, sweet, innocent Princess was becoming such a wild little thing and it was all for him.

Billy kept his footsteps light as he made his way over to Sidney's bed, his heartbeat thundering with anticipation as he reached her. Pulling the comforter off of her, he was greeted by the sight of her wearing his favorite blue shirt. It was so long that she was using it as a nightdress, her long creamy legs completely exposed.

Something primal filled his chest as he stared at her makeshift pajamas and he licked his lips, wanting nothing more than to rip it right off of her. Instead, he climbed on top of her, the bed dipping slightly with his weight. Reaching out, he gripped the hem and raised the shirt up to her neck. To his pleasant surprise, he found her completely bare beneath the shirt, no panties or even some kind of sports bra in sight.

Billy felt his cock strain painfully against his jeans, but he didn't remove them just yet. He slid down her body, spreading her legs wide and staring at her pussy, his pupils blown with desire. Her pink folds glistened under the moonlight streaming in through her open window, causing him to run his tongue over his bottom lip. He couldn't wait to taste her.

"Dirty girl, already wet for her Daddy," he whispered roughly into the silence, using his first two fingers to gather some of her wetness and rub circles on her clit. A smirk crossed his face as she moaned softly, squirming a bit in her sleep from his light touch. When he pressed the pads of his fingers against the sensitive bundle of nerves, she arched her back and a whine left her lips, instinctively attempting to follow and increase the stimulation.

Billy thrust his fingers deep inside of her pussy, another loud whine coming from the sleeping girl. Repeatedly slamming his fingers in and out of her soaking entrance, Billy wrapped his lips around her nipple, sucking hard on it as he worked his digits through her folds.

Little cries of pleasure came from Sidney, her brows scrunching together and hands clenching the comforter as her body responded to her boyfriend's ministrations.

Billy moaned around her nipple when he felt her tighten around his still pumping fingers, the sound vibrating the sensitive skin of her breast. She went wild underneath him at the feeling, desperately bucking and rolling her hips. With one hard thrust into her pussy, his fingertips brushing her g spot, she cried out as she came.

Billy removed his mouth from her nipple with a pop and moved his head back to look at her, entranced by the way she looked, so beautiful and breathless. As he sucked her cum off of his fingers, savoring the familiar sweetness, it thrilled him knowing that he could make her experience an orgasm as intense in her sleep as it was when she was awake.

He wasn't finished, though.

He wanted to eat her out, to taste her properly, but the aching in his cock became too painful to ignore. He had to be inside her now.

Undoing his jeans, Billy slid them and his boxers down his legs, exposing his hard cock. Taking it into his hand, he gave it a few hard strokes before lining it up with Sidney's entrance and burying himself to the hilt inside of her pussy, his hips flush against hers.

The growl that ripped itself free from his chest was nothing short of animalistic. She was always so tight, but it felt even better this way. He found a pace that was somewhere between gentle and rough, trying not to jostle her so much that it woke her up, but damn it was difficult. The way she wraps perfectly around him, the little gasping moans that escaped her with each delicious movement into her body…it was fucking fantastic and he just wanted to pound into her.

Billy closed his eyes, basking in the feeling while attempting to focus on the rhythm he established.

A breathy "Billy" made his eyes snap open and look down at Sidney in alarm. Did he wake her up? Was their kink night ruined now that she wasn't asleep?

No. Neither was the case.

Sidney was still asleep, but her mouth was open and her face was flushed, moans of ecstasy repeatedly falling from her lips. She was dreaming of him fucking her!

That realization made him growl and he decided to hell with his set speed. He began pounding into her just like he wanted to earlier, his cock slamming harder, deeper, and faster into her pussy, the tip kissing the mouth of her womb. He didn't care anymore, he just wanted to fill her and make her feel it in the morning.

"So needy," he grunted lowly, gripping her hips hard and repeatedly driving himself in and out of her. "Even in your dreams you imagine Daddy fucking you, huh, Princess?"

She clenched harder around him, and he growled again. "My dirty little Princess…enjoying having a cock stuffing your pussy while you're asleep, all spread out and vulnerable…Fuck, I'm gonna cum…"

He let go of her hips and brought her legs up to his shoulders before returning his hands to their previous position, groaning in pleasure as he bottomed out, his cock punching deep into her womb before he let go, hot cum spilling inside of her, the contractions of her tight little hole as she came milking him for everything he was worth.

Billy buried his face in her neck, his hot breath hitting her skin as he panted, his hips moving for several minutes to ride out the intensity of his orgasm.

When he finally calmed down, he gave her a loving kiss on her neck and pulled out, lowering her legs to the mattress. He felt himself twitch again when he saw some of his cum spilling out of her pussy.

"So fucking beautiful, Princess," he whispered reverently, caressing her cheek and smiling when she sighed and nuzzled into him.

"I love you so much," he told her, pulling his shirt down over her body and covering her with the comforter before redressing his lower half. Giving Sidney a soft kiss on her lips, Billy climbed out of her window and made his way back to his house, feeling much lighter than he did earlier in the day.
