Faced with that insane temptation, I thought about it for a few seconds, then grinned. "Pleasure doing business with you."
I know my dad well. He's super strict about grades, but everything else? He basically lets me do whatever. It was Mom who always controlled my sex life and kept me on a tight leash.
Even if I actually fucked my stepmother's pussy, Dad would probably just laugh and say, "You've got guts, kid. Worthy of being my son."
Hearing my answer, my stepmother's smile grew even wider. She parted her red lips slightly and said, "Pleasant to cooperate."
The moment we sealed the deal, all the tension between us vanished, and our relationship instantly felt much closer.
Suddenly I felt something soft rubbing my crotch under the table. I looked down and saw my stepmother's small, black-stockinged feet slowly stroking my cock through my pants. Grinning, I grabbed her ankle, pulled her foot up, and ran my tongue slowly across her sole. She squeaked from the ticklish feeling and quickly pulled it back, face turning cute and shy.
I looked up and saw her flustered, girlish expression for the first time.
Noticing my stare, she hurriedly fixed her clothes and hair to hide her embarrassment, coughed lightly, and asked, "Shall we cook after we finish eating?"
"Whatever you say," I answered with a huge, happy smile.
Hot pot is the fastest meal possible. Soon the pot was bubbling on the table with all kinds of meat and vegetables ready. The broth was the super-spicy kind we both loved. I only just realized my stepmother loves spicy food too.
"No wonder you've been constipated these past few days. Too much heat rash down there," I teased, looking at my stepmother.
"Ugh, don't say such embarrassing things while we're eating!" She shot me a playful, flirty glare, then smirked proudly. "Anyway, I'm not scared of constipation anymore. With this slutty bitch ready to help me with my bowels whenever I need, what do I have to worry about? Right?" While saying that, she reached over and gave Mom's big, sexy ass a casual pat, then slid her hand between Mom's legs, pulled out the soaked pink vibrator, completely covered in thick, lustful pussy juice and tossed it aside. Then she gripped the anal dilator, yanked it free with a loud, wet pop, and threw that into the toolbox along with the vibrator.
Even though my stepmother had finally removed the dilator, Mom's anus had been forced wide open all morning long, so it couldn't snap back to its normal closed state yet. It could only twitch and squirm helplessly, still gaping wide.
Mom let out a short, pathetic groan of pain mixed with relief. Her gaping anus twitched helplessly in the open air. Then she lowered her head even more, almost touching the floor, and answered my stepmother in the most humble, pleading, eager-to-please voice she could force out.
"Mmm, Grandma is absolutely right," Mom whimpered, her voice trembling with pure humiliation. "From now on, if Grandma ever gets constipated again, your filthy, worthless, slutty granddaughter Linda will definitely crawl over and serve you properly with her tongue until you feel completely relieved."
"See? I told you from the very beginning you were nothing but a dirty, disobedient bitch who needed real discipline," my stepmother said with a triumphant, mocking laugh. "Now look at you, so sweet, so obedient, so quick to kiss ass when you finally learn your place. Today I officially become my precious baby's mother. Go fetch the best bottle of wine from the cellar right now. We're celebrating properly."
"Yes, Grandma…" Mom answered instantly. She turned and crawled on all fours toward the wine cellar like the broken pet she had become. She carefully selected the most expensive bottle we owned, poured two full glasses with shaking hands, one for me and one for my stepmother, and brought them back on her knees, head bowed low the entire time.
My stepmother took a long, satisfied sip, then wrinkled her eyes playfully. "My poor little feet are absolutely killing me after wearing those sky-high heels all day long. Come here, you useless old cow, and give them a proper, thorough massage with those big, fat, slutty tits of yours."
Mom obeyed at once. She stretched out flat on her back beneath my stepmother's chair, her lower body facing me so I had a perfect, humiliating view of everything. My stepmother lifted one delicate, black-stockinged foot and pressed it firmly onto Mom's full, heavy breasts. The soft, milky flesh instantly sank deep around her foot, then bounced right back up with perfect elasticity, like the world's most luxurious jelly.
It was my stepmother's very first time ever stepping on another woman's breasts. Curiosity sparkled in her eyes as she pressed down harder. "Boing". The flesh sprang back again and again.
"You know, these massive breasts of yours are actually pretty damn comfortable to step on, you disgusting old whore," she teased, wiggling her toes deeper into the warm, yielding flesh. "Don't just lie there like a dead fish. Use your hands. Hold my feet steady on your disgusting, slippery tits so I can really enjoy this."
While constantly piling more and more meat onto my plate and saying, "Eat up, darling, you're way too skinny, you're going to need all the energy you can get later tonight," my stepmother made Mom grab her ankles tightly so her tender soles could slide and grind freely across those huge, elastic breasts. Mom's hard, humiliated nipples poked and rubbed against every sensitive spot on the soles of my stepmother's feet.
Girls' feet are incredibly sensitive, and with Mom working so desperately to please her, soft, needy little moans started escaping my stepmother's lips almost immediately.
"By the way, Stepmother," I said between huge mouthfuls of delicious spicy beef because I was absolutely starving, "when exactly is the wedding with Dad? I definitely want to take a day off school so I can be there for it."
