Fantastic Isaac [English]

Birthday Gift [Marc Spector] - SMUT

Warning: Marc is the step-uncle of Y/N

"Y/N, come on down! Marc is here!" her mother called out. Marc was her uncle, or rather step-uncle; her mother married his twin brother Steven two years ago. She liked Steven and he was always nice to her. Of course, she couldn't deny that both Steven and Marc were also quite attractive. Y/N couldn't understand why Steven could marry someone like her mother, even after two years she still asked herself that every day. He deserved better and yet she doubted he knew it, he was too kind; that was the difference between Steven and Marc, Marc didn't care about hurting anyone's feelings. It was also one of the reasons why he hardly ever came over when her mother was home. However, today was Y/N's birthday and she wanted him to come to her party and he has never denied her a wish. She finally went downstairs and to the living room. The two brothers were sitting next to each other talking; however, the conversation stopped when she stepped into the living room. Marc turned to her and smiled before standing up.

"There's the birthday girl," he said, leaning down to kiss her cheek before whispering in her ear, "That dress looks wonderful on you."

"Thank you," she said, returning his smile and biting her lip.

"So who else did you invite?" asked Marc, raising his eyebrows. "Am I going to have to deal with a bunch of teenagers later?"

She laughed and shook her head. "No, I didn't invite anyone, just you."

"Then I'm honored." She bit her lower lip and looked at him through her lashes.

"I hope you remembered my gift, though," she said; she pressed a finger to his chest "Would you like a drink?"

"I'd love one," he replies. She turned and walked to the kitchen. Y/N could feel his eyes on her butt, enjoying his gaze on her body.

"Of course I thought of your gift!" he called after her. She looked over her shoulder for a moment before walking into the kitchen and taking out a beer.

"Was it really necessary for you to invite him?" her mother asked as she stepped into the kitchen.

"I like Uncle Marc," she said, shrugging her shoulders.

Y/M/N crossed her arms in front of her chest, "He's not really your uncle."

Fortunately, Y/ thought, but did not speak it. Without answering, she returned to the living room and heard her mother walking up the stairs. She stopped when she heard the two men talking.

"That's my stepdaughter, Marc!" said Steven. Y/N glanced around the corner a bit and saw Marc shrug his shoulders.

"So what? Don't act like you don't like fucking her too," he spoke, not caring who heard them.

"First, keep your voice down," Steven said, "Second, this is so wrong; I love her mother and I'm happy with her"

"Stop lying to yourself."

She could see Steven step closer to him and point his finger at his brother. "She's off limits."

Without another word he left the room; when she looked up she saw Marc looking in the direction of the kitchen and looked at her and smiled knowingly. He stepped toward her and took the beer from her hand. Marc took a sip before leaning down to her and pressing his lips to hers for a moment. She froze for a moment before kissing him back, but then he broke the kiss and looked at her with a smile.

"I hope you're ready for your gift," he said before also leaving the living room.

-----------------------------------------------------

It was later in the evening and everyone, except for her mother, decided to watch another movie together. She sat between Marc and Steven on the sofa with a big blanket over them. It was from halfway through the movie when she felt a hand on her thigh. She looked to Marc in confusion, but he was still looking at the TV. His hand moved further up to the waistband of her sweatpants. Y/N looked to Steven, who had fallen asleep when Marc's hand slipped into her pants. She spread her legs to give him better access and leaned back. Out of the corner of her eye, she could tell he was smiling a little. She bit her lip as his fingers slid over her panties before he pulled them aside and stroked the crease of her pussy; she tried to stifle her moan as he pushed two fingers inside her. Marc leaned down to her and whispered, "You're so tight, I can't wait to feel you around my cock."

Slowly he began to fuck her with his fingers and rub her clit with his thumb. She raised her hips to meet his thrusts. But then he stopped and stood up, the blanket falling off him; she could see his erection pressing against the fabric of his pants. When she looked up at him, his eyes were dark with lust. He pulled her up and kissed her passionately before bending her over the sofa. Marc pulled down her pants and panties; she looked at Steven, who was still asleep, and then at Marc, who had already pulled his cock out of his pants.

"What if he wakes up-" she started to ask him, but didn't get far as he thrust into her in one hard thrust. To muffle her moans, he quickly put a hand over her mouth.

"Then he gets the show of his life," he says softly in her ear as he began to fuck her at a fast and hard pace. Marc wrapped a hand around her throat and pulled her up so that her back pressed against his chest. He kissed her neck and nibbled on her skin. His other hand began massaging her breast and rolling her nipple through the fabric of her shirt between his fingers. Marc pulled almost completely out of her before thrusting back into her. He repeated it over and over, letting his hand travel down to her clit. Hastily he began to rub it and she felt her climax building inside her.

"Come for me," he growled in her ear and instantly her body stiffened.

"Marc..." she moaned as she reached her orgasm. He thrust deep into her pussy one last time before filling her with his hot cum. They both breathed heavily as they recovered from their orgasms, not hearing Steven wake up next to them.

"Oh my God, Marc!" he said, sitting up. Marc's cock slid out of her and his cum flowed over the inside of her thigh. She heard him pull up his pants and close them.

"Don't act up," he said, annoyed. Y/N also pulled up her panties and pants as she blushed. "Maybe next time you'll even get to join in, I think Y/N would enjoy it."
