Mom had been acting different ever since Dad left for his month-long job trip. She walked around the house in nothing but a thin tank top and panties, her heavy tits swaying, nipples poking out like she wanted me to notice.

I was twenty-two, home from college for the summer, and every time she bent over I caught a flash of her shaved pussy lips through the cotton.
One night I came downstairs for water and found her on the couch, legs spread, fingers sliding in and out of her wet cunt while she watched porn on her phone. She didnt even try to hide it. Come here, baby, she said, voice low and rough. Youre a man now. You know what this is.
I stepped closer, cock already stiff in my shorts. She reached out, grabbed my waistband and yanked them down. My dick sprang free, thick and leaking. Mom wrapped her fingers around it and gave a slow stroke. Fuck, youre bigger than your father, she muttered, then leaned in and swallowed half of me in one hot, wet pull.
I groaned and grabbed her hair. She sucked hard, spit running down my shaft, tongue working the underside while she fingered herself faster. The wet sounds filled the room. When she pulled off she looked up at me, lips shiny. You want to fuck your mother? Say it.
I want to fuck you, Mom, I growled. I want to shove my cock in that pussy youve been showing me.
She stood, stripped the tank top off, and pushed her panties down. Her tits were full and soft, nipples dark and hard. She turned, bent over the arm of the couch, and reached back to spread her ass. Then do it. Fuck your mother like youve been jerking off thinking about.
I lined up and slammed in. She was soaked, tight heat gripping every inch. I fucked her hard, hips slapping against her ass, watching my cock disappear into her again and again. Mom moaned loud, pushing back to meet every thrust. Thats it, baby, give Mommy that dick. Fill me up.
I reached under her, grabbed her tits, pinched her nipples while I pounded deeper. She came fast, cunt pulsing around me, juices dripping down her thighs. I didnt stop. I pulled out, flipped her onto her back on the couch, and drove back in, watching her face while I fucked her.
Tell me you love it, I said, grinding against her clit.
I love my sons cock, she panted. Ive wanted it for years. Come in me. Come in your mothers pussy.
I slammed deep and unloaded, thick ropes of cum pumping into her while she milked me with her walls. We stayed locked together, breathing hard, sweat-slick skin pressed close.
After a minute she smiled, slow and filthy. Round two in my bed. This time I want you to eat it out of me first.
We moved to her room and didnt leave until morning. By then shed ridden me, Id taken her from behind again, and shed sucked me clean twice. The taboo line was gone. All that was left was the raw need, and we fed it every night after that.
