She walked into the living room and saw him on the couch, shorts around his ankles, fist pumping his hard cock like he was trying to break it. Eighteen years old, home from his first year at college, and still jerking off like a desperate kid.
"Fuck, Mom," he gasped, trying to cover up, but it was too late. His dick was thick, veiny, leaking at the tip.
"Don't stop on my account," she said, voice low and rough. She kicked the door shut and crossed the room. "That's a nice cock you've got there. First time anyone's seen it?"
He nodded, face red, but his hand stayed on it, squeezing. She dropped to her knees right in front of him, pushing his thighs apart. "Then let's fix that. Mom's gonna give you your first blow job. You want that?"
"Yeah," he breathed. "Please."
She wrapped her fingers around the base, stroking slow and tight. "Good boy.

Open your legs wider." Her tongue flicked out, licking the head in one long swipe, tasting the salty precum. He groaned loud. She did it again, circling the crown, then sucked the tip into her mouth, lips sealing tight.
She took more, inch by inch, until her nose brushed his pubes. His cock filled her throat, hot and pulsing. She bobbed her head, sucking hard on the upstroke, tongue pressing flat along the underside. Spit ran down his shaft and over her fingers as she jerked the base in time with her mouth.
"Fuck, that feels so good," he panted, hips twitching. She pulled off with a wet pop, strings of saliva connecting her lips to his dick.
"Talk dirty if you want," she said. "Tell me how my mouth feels on your cock."
"Hot. Wet. Like you're trying to suck the cum right out of me."
She smiled and went back down, faster now, cheeks hollowing. One hand cupped his balls, rolling them gently while she worked his shaft. He was close already, thighs shaking. She eased off, licking down to his balls, sucking one into her mouth, then the other, while her fist kept stroking.
"Don't cum yet," she warned. "I want to feel you throb when you shoot."
She climbed up, straddling his lap for a second, rubbing her wet pussy along his cock without letting him inside. Then she slid back down to her knees and swallowed him whole again. This time she went deep, gagging a little on purpose, letting him feel her throat squeeze.
His hands found her hair, not pushing, just holding. "Mom… I'm gonna…"
She pulled back just enough to talk around his cock. "Do it. Fill my mouth. First load down my throat."
He came hard, thick spurts hitting her tongue. She swallowed every drop, sucking until he was dry and twitching, then licked him clean.
She stood up, wiping her mouth with the back of her hand. "Next time you want your cock sucked, you come find me. Understood?"
He nodded, still breathing hard, dick softening but already starting to twitch again. "Yes, Mom."
She turned and walked out, leaving him there with his shorts down and a new lesson learned.
