She had been watching him all evening, her eyes lingering on the way his jeans hugged his ass when he bent over to grab another beer from the fridge. At twenty-two, her son was all man now, broad shoulders and that thick bulge she couldn't stop noticing. The house was quiet, just the two of them after his dad left for the week. She poured herself a third glass of wine and felt the heat building between her thighs.
"Jake, come sit with me," she called from the couch, patting the spot right next to her. He dropped down, close enough that their legs touched. She turned toward him, letting her robe slip open a little so he could see the swell of her tits. "You've been staring at these all night. Don't think I haven't noticed."
Jake's face flushed but his eyes dropped straight to her cleavage. "Mom, fuck… I didn't mean to."
"Yes you did." She reached over and grabbed his hand, pressing it against her breast. "Feel how hard my nipple is? That's for you." His fingers squeezed on instinct, and she moaned low. "That's it. Squeeze Mommy's tit."
She leaned in and kissed him hard, tongue pushing into his mouth. He kissed back after a second, hungry, his other hand sliding up her thigh under the robe. She spread her legs so his fingers found her bare pussy, already slick. "Rub my clit," she ordered. "Make it wetter for your cock."
Jake groaned into her mouth as he circled her swollen nub with two fingers. She reached down and yanked his zipper open, pulling out his thick cock. It was heavy in her hand, the head already leaking. "Goddamn, son, you're bigger than your father. Stroke it while you finger me."
They jerked each other off like that for a minute, breathing hard, until she couldn't take it. She pushed him back on the couch and climbed on top, grabbing his cock and rubbing the head up and down her wet slit. "You want to fuck your mom? Say it."
"I want to fuck you, Mom," he growled. "I want to shove my cock in your pussy right now."
She sank down in one slow motion, taking every inch until her ass rested on his balls. They both moaned at the same time. She started riding him, rolling her hips so his cock dragged against her walls. "That's it, fill Mommy's cunt. Fuck, you feel so good inside me."
Jake grabbed her hips and thrust up to meet her, pounding into her. The wet sounds of his cock slamming into her soaked pussy filled the room. She leaned forward so her tits hung in his face. "Suck my nipples while you fuck me."
He latched on, sucking hard while his hips bucked. She reached between them and rubbed her clit fast, feeling her orgasm building. "Don't stop, baby. Mommy's gonna come on your cock."
She came hard, pussy clenching and gushing around him, juices running down his shaft. Jake flipped them over without pulling out, throwing her legs over his shoulders and driving into her deep. The couch creaked under them.
"Harder," she demanded. "Fuck your mother like you mean it. Fill me up."
He slammed into her, balls slapping against her ass with every thrust. She reached down and spread her cheeks so he could see everything. "Look at that pussy taking your dick. Come inside me, Jake. Give Mommy your load."
Jake grunted and buried himself to the hilt, cock pulsing as he pumped thick ropes of cum deep into her.

She felt every spurt, her walls milking him until he was empty. He stayed inside her, breathing hard, while she stroked his back.
After a minute she pushed him onto his back again and slid down to take his softening cock in her mouth, tasting their mixed cum. "We're not done," she said, licking him clean. "Mommy wants that cock in her ass next."
Jake's dick twitched back to life in her hand. She smiled and turned around, presenting her ass. "Come get it, son."
