I walked into the kitchen that night wearing nothing but a thin tank top and panties, thinking the house was empty. My son, Jake, was supposed to be out with friends. Instead he was sitting at the table, staring at his phone, shirtless, sweat still on his chest from the gym. He looked up and his eyes locked on my nipples pressing hard against the fabric.
"Fuck, Mom," he said, voice low. "You can't walk around like that."
I didn't cover up. My pussy got wet instantly. "Like what? Like your mother who hasn't been touched in years?"
He stood up slow. His cock was already pushing against his shorts. "Don't say shit like that unless you mean it."
I stepped closer until my tits brushed his chest. "I mean it. You've been watching me for months. I know you jerk off thinking about this."
Jake grabbed my ass with both hands and squeezed hard. "Then stop talking and show me."
I dropped to my knees right there on the kitchen floor. Pulled his shorts down. His cock sprang out thick and veined, already leaking. I wrapped my lips around the head and sucked him deep, tasting salt and skin. He groaned and thrust forward, fucking my mouth while I gagged on it.
"Jesus, Mom, your mouth feels so fucking good."
I pulled off long enough to say, "Take me to your room. I want you to fuck your mother like you mean it."
He lifted me up and carried me upstairs. My legs wrapped around him. As soon as the door shut he ripped my tank top off and sucked my nipples hard, biting just enough to make me moan. Then he shoved my panties aside and pushed two fingers straight into my dripping cunt.
"You're soaked," he growled. "You've been wanting this."
"Shut up and fuck me."
He threw me on the bed, spread my legs wide, and slammed his cock into me in one rough thrust. I cried out, back arching, as he started pounding. The wet sound of skin slapping filled the room. Every stroke hit deep, stretching me open.
"Harder," I begged. "Fuck your mom harder."
Jake flipped me onto my stomach, yanked my hips up, and drove back in. He reached around and rubbed my clit while he fucked me from behind, grunting with every thrust. I came first, shaking and screaming into the pillow, my pussy clenching around his cock.
He didn't stop. He kept slamming until I felt him swell and then he flooded me, hot cum pumping deep inside. When he pulled out it leaked down my thighs.
We lay there breathing hard. Then he rolled me over and started licking his own cum out of my pussy.
"Round two," he said against my clit. "I'm not done with you yet."
By morning we'd fucked in every position I could think of.

Shower. Against the wall. Me riding him while he sucked my tits. He came inside me three more times. We didn't talk about stopping. We just kept going until the sun came up and we both knew this was only the first time.
