... the kids might see."

Matt chuckled at her worry. "I'll bet Lily is upstairs listening to that awful stuff she calls music, and you said Matt was down with a headache."

"Oh babe, I would love too, really, but..."

Matt turned her around, pressing his mouth against hers, kissing her using the instincts inside his dad's mind. She responded, her tongue tangling with his as she raised her arms and wrapped them around his neck. He moved one hand to the small of her back, holding her close, the other slipping between them to undo the buttons on her blouse. "The... the kids," she moaned between kisses, but Matt just ignored her, his hands going from button to button until the last one popped free. He stopped kissing her, looking into her eyes as his hands parted her shirt, exposing her bare breasts.

Helen just looked up at him, her eyes on his as he leaned back, looking at her breasts. Matt couldn't remember ever seeing his mom's bare breasts, and for a moment he regretted not trying to take a peek before, but now was not the time for regret. He started kissing her again, on her mouth, on her chin, getting lower and lower until he was kneeling before her, his arms around her waist, his mouth at her breasts, kissing, licking, sucking. Matt's dad had shorter hair, and his mom was running her fingers through the hair he had, pulling his head against her. "You... you haven't done this in a while," she moaned.

Matt nibbled on her nipple as his hands moved to the buttons on her pants, pulling them down around her ankles, then lifting each foot to take the fabric past her feet, suckling on her breast the entire time. His mom had obviously had a change of heart, helping him by lifting her feet. He pulled her panties down next, exposing her neatly trimmed bush. Matt leaned back on his ankles, looking at his mom's body, and licked his lips. He had seen enough porn to know what to do next, and he leaned forward, pressing his mouth against the cleft between her legs.

His knowledge of porn, and the instincts in his dad's brain, gave him an edge as he flicked her clit with the tip of his tongue and making Helen spread her legs wider. "Hop up," he muttered between licks, his hands on her thighs as she raised her ass to the countertop, sliding on the surface as Matt kept licking, moving his tongue from her clit to her vagina and back, pressing between her labia as deep as he could before moving back to her clit. She raised her legs to his shoulders, giving him better access to lick her. Apparently she had completely forgotten her worry that they might be interrupted.

Then her legs tightened around his head, and Matt could feel her body tensing up, knowing he had just made his mom cum, pulling her closer to the edge as he kept working on her with his tongue. He kept licking, loving how his mom tasted, until her legs relaxed. He looked up at her face, grinning, his mouth coated with saliva and her sexual juices. Her fingers tightened in his short hair, gently pulling him to his feet. "Fuck me, Nate," she purred, her legs spreading wider, her hands going to his pants.

Matt could only watch as she undid his pants, a cock shorter but thicker than he was used to popping free, as if pointing at his mom's slick pussy. "I can't wait to feel that inside me," she moaned, wrapping her legs around his waist and pulling him forward, one hand still on his cock to guide it into her pussy. He let her lead, looking between them to watch his cock disappear inside his mom, not looking away until the entire shaft had disappeared inside her. Then he looked at her face, eyes locked on hers as he began to pump. Neither of them looked away as he thrust again and again, Matt watching and feeling as he fucked her to two more orgasms. Then he felt his own orgasm wash over him, and Matt pressed his cock as deep inside his mom as he could, his cock throbbing, spurting, filling her womb with semen.

As he came, he leaned forward, locking lips with her, tongues twisting, both of them panting with pleasure and lust, Helen pushing her upper body against him, only his shirt separating their flesh. They kissed until after his orgasm ebbed, his cock still deep inside her. Matt moved his head next to hers, hearing her panting, knowing she could feel his own breath on her ear. "Where did that come from?" Helen asked. "I don't remember the last time I had three orgasms!"

Matt could only smile. "I guess I'll have to work on it more," he said, pulling back to look at her, his movement making his cock slip out of her. He could see a string of cum stretch between them, then snap, dripping on her puddled clothes. "You're just so beautiful," he breathed, looking her body up and down.

Helen smiled too, reaching out and grasping his softening cock. "I still want to know what got you all riled up," she murmured, giving him a squeeze.

"This wonderful body did," Matt said, reaching out and cupping both breasts, thumbs playing with her nipples, "but we should really get dressed. The kids won't stay in their rooms forever."

"Oh, my god," she gasped, hopping off the countertop and reaching for her clothes. A moment before Matt jumped into his own body, though, she leaned forward and planted a quick kiss on the still dripping tip.

Still laying in bed, Matt smiled again, his cock getting hard with the memory of having sex with his mom, and he vowed to himself that it was an experience he would repeat as often as he could.
