The next morning the renovation crew was hammering and drilling downstairs again, but upstairs Sophia had locked the bedroom door and turned the tiny space into her private classroom.
Mia was still leaking from last night. She'd slept on the bottom bunk with her legs slightly spread, no panties, my final creampie slowly drying in shiny streaks down her inner thighs. Sophia had made her keep it inside—"Good girls hold their lessons until morning," she'd whispered before kissing us both goodnight.
Now Sophia stood naked in the center of the room, heavy tits swaying as she pointed at the bunk like it was a stage.
"Deepthroat Academy is now in session," she announced with that calm, maternal smile that somehow made everything ten times filthier. "Mia, on your knees. Alex, sit on the edge. And remember—zero noise. The crew is right below us."
Mia's cheeks burned, but her eyes blazed with competitive fire. She dropped between my legs wearing only her tiny tank top. Fresh cum glistened at her pussy lips as she settled.
Sophia knelt shoulder-to-shoulder beside her stepdaughter, both faces inches from my hardening cock.
"Lesson two," Sophia said softly, wrapping a hand around my shaft and stroking slow and firm. "You swallowed once last night, princess, but that was just the warm-up. Today you learn how to take every inch like Mommy does."
She leaned in first—demonstration time. Lips parted, she took me straight to the root in one effortless glide, nose pressed flush to my stomach, throat rippling around me like warm velvet. She held it there, eyes locked on Mia, then pulled off with a wet pop and a long spit string.
"Relax your throat. Breathe through your nose. No teeth. And when he hits the back… swallow." She demonstrated again—deeper, slower, humming so the vibration made my balls ache.
Mia watched, one hand already rubbing her cum-filled pussy, thighs trembling.
"Your turn," Sophia said, guiding Mia's head forward. "And keep Mommy's load inside you while you practice. I want it dripping out every time you gag."
Mia opened wide. She took the head easily, then pushed deeper—halfway—before her throat convulsed and she gagged hard, pulling back with watering eyes and messy spit strings.
"Too fast, baby girl," Sophia cooed, stroking Mia's hair. "Slow. Let Mommy help."
Sophia wrapped her hand around the base and fed my cock into Mia's mouth herself, controlling the depth. "Breathe… swallow… good girl… deeper… there we go."
Mia's lips stretched obscenely. Inch after inch disappeared. Sophia kept one hand on the back of her head, gently pushing until Mia's nose was almost touching my stomach. The other hand slid between Mia's thighs, two fingers scooping a thick glob of last night's cum from her pussy.
"Swallow around him," Sophia whispered, smearing the warm load across Mia's stretched lips. "Taste what you're earning."
Mia moaned around my shaft—the vibration shooting through me. Her throat opened. She took the last inch, nose pressed flush.
Sophia beamed. "That's my good girl. Hold it… now bob. Just like Mommy showed you."
Mia started moving—slow, sloppy, gagging every few strokes but fighting through, spit and cum dripping down her chin onto her tits. Sophia stayed right there, coaching in that soft, filthy voice:
"Eyes up, princess. Look at him while you choke on it." "Deeper on every downstroke." "Tongue right here—yes, just like that." "Feel how full your pussy still is? That's your reward for taking Mommy's lesson."
The crew downstairs fired up a power saw. The grinding roar covered the wet gagging sounds, but the risk made everything hotter. Mia's bratty side ignited—she started matching Sophia's rhythm, pushing herself further, throat bulging visibly every time she took me to the root.
Sophia's smile sharpened. "Feeling competitive today? Think you can out-deepthroat Mommy already?"
Mia pulled off with a gasp, spit everywhere, eyes blazing. "Watch me."
She dove back down—faster, greedier, taking me balls-deep on her own. Sophia laughed softly, delighted, and leaned in to lick the side of my shaft where Mia's lips couldn't quite cover.
They worked me together—Sophia licking and coaching, Mia sucking like she was fighting for a trophy. Warm throat, wet tongue, two sets of hungry eyes looking up at me.
"I'm close," I groaned.
Sophia's fingers sped up inside Mia. "Swallow every drop, princess. Show Mommy you've learned."
Mia slammed down one last time, throat squeezing tight, and I exploded—thick ropes shooting straight into her stomach. She held me there, swallowing greedily around every pulse, until Sophia gently pulled her off.
Mia's lips were swollen and shiny, a thin trail of cum leaking from the corner of her mouth. She looked up at Sophia with pure bratty triumph.
"Beat that, Mom."
Sophia just smiled wider, leaned in, and licked the stray cum from Mia's lips in a slow, filthy kiss.
"Oh, baby girl… the competition has officially started." She stood, still naked, and kissed my forehead like a proud teacher. "Tonight we move to creampie control—who can make Alex produce the biggest, thickest load. Loser wears the winner's cum-soaked panties to college tomorrow."
Class dismissed… for now.
Mia stayed on her knees, thighs shiny with fresh drips, already plotting her next move.
The rivalry wasn't coming. It was here.
