Excitement

"Do you think we'll be able to finish before mom gets home?" Lily asked, raising a hand to play with the end of her braid.

"Yeah," Matt breathed, moving his eyes up and down her body again.

"You sure about that? Last time we barely finished before she got home," she giggled, twisting the end of her braid around her finger. "Do you have any idea how tough it was to pretend you weren't hiding behind the bed while your cum was still leaking out of me?"

Matt could only shake his head, and Lily stepped forward, her hands moving to the buttons of his shirt. He could only watch her hands moving from button to button, his eyes moving from her hands to her breasts and back until those hands finished with the last button, moving from the shirt to the zipper tab of his pants.

Although Lily seemed to know what she was doing, Matt's impatience won over, and he reached between them and unbuttoned the top of the slacks, which promptly fell around his ankles. Apparently his dad didn't wear underwear - his cock sprang up and into Lily's waiting hand. "You are excited tonight, dad," she murmured, stroking his cock with a practiced motion. "What got you so excited?"

Instead of waiting for an answer, though, she sank to her knees in front of him, not taking her hand off his cock until her mouth wrapped around the tip. Matt could barely breathe as he realized his twin sister was, quite willingly, sucking their dad's cock. Her eyes turned up to him, looking at him as she moved her mouth up and down his shaft, one hand moving with her mouth, the other cupping his balls. "Oh god," Matt moaned, his hands going to the sides of her head, the braids between his thumb and forefinger as he moved his hands with her head.

Lily pulled her mouth off his cock, licking her lips and grinning. "You like that daddy?"

"Love it," Matt groaned. She just grinned again, pushing her mouth back onto his cock. Her hand had moved to her breast, allowing her mouth to take his cock deeper. He watched as she worked as hard as she could to get it deeper, her eyes widening as the tip hit the back of her throat. She tried again and again, gagging each time, but couldn't get the last inch or so past her sensual lips.

He had never thought he would even catch Lily giving a blowjob, and had never dreamed he would see her giving one in this position. Then, all too soon, she was pulling away again, rising from her knees to stand in front of him. "You are fantastic," he breathed, leaning down and locking his lips on hers. She kissed him back, her tongue wrestling with his, not flinching as she felt his hands circle around to her back, pulling her naked body against his.

Lily broke the kiss, stepping back and out of his embrace, her eyes never leaving his face. She kept backing up, not even looking as the backs of her thighs hit the bed, her hands going behind her as she worked her way up to lay her head on the pillow. "Well, what are you waiting for?"

Matt crossed the room, led by his hard cock, shrugging the shirt off his shoulders as he crawled onto his sister's bed, and between her raised and spread knees. "I've been looking forward to this all night," she sighed, reaching between them, her hand finding his cock and guiding the tip to her pussy. "Do it, dad."

He pushed his hips down, feeling his cock slide through her hand, then the tip pressed into something tighter than he had ever felt in his own body. He kept pushing until his pubic hair pressed hard against her shaved skin, gasping at the same time as Lily did. "You're filling me up," Lily groaned.

"You feel so good," Matt replied, pulling his hips away until just the tip remained inside his sister, then thrust down, eliciting another moan from the eighteen year old girl's mouth. He repeated again and again, Lily's legs wrapping around his ass, pulling him down every time he raised his hips.

There was no way to tell how long Matt fucked Lily. All he could focus on was the sensation of his cock sliding in and out, and the sight of his twin sister lying under him as he thrust. "I'm gonna cum," he groaned, trying to pull out, but Lily locked her ankles behind his ass, her arms around his neck, and raised her head to his.

"Cum inside me, daddy, I want to feel it," she whispered, and Matt drove deep inside her, his cock spasming as he filled his sister with semen. He held his cock deep inside her until long after his orgasm ended, hearing Lily pant into his ear, feeling her B cup breasts press against his chest with each pant. "I always love that feeling."

"And what feeling is that?" Matt panted into her ear.

"Feeling my dad's cum filling me up," Lily giggled.

Matt smiled, relishing the feeling of his sister's pussy, then jumped back into his own body. This was a day he'd remember for a long time - and a day he would repeat whenever he could.
