The house was quiet except for the wet sounds coming from the living room.

Lisa, twenty-two and home from college, stood frozen in the hallway with her overnight bag still in her hand. Her stepmom, Diane, was on the couch, naked from the waist down, legs spread wide while her step-sister Rachel knelt between them. Rachel had the thick black strapon buckled around her hips and was driving it into Diane with hard, steady thrusts. Dianes head was thrown back, mouth open, tits bouncing with every slam.
Fuck yes, baby girl, Diane growled. Give it to me just like that. Deeper.
Rachel grunted and shoved harder, the harness slapping against Dianes ass. You like your stepdaughters cock, Mom? You like getting pounded in the middle of the day like a dirty slut?
Lisas bag hit the floor. Both women looked up. Dianes eyes lit up instead of showing shame. Theres my other girl. Come here.
Rachel didnt stop fucking. She just grinned over her shoulder. Took you long enough. Get naked and get over here.
Lisas heart hammered, but her pussy was already throbbing. She stripped fast, leaving clothes in a trail on the carpet. Diane held out a hand and pulled her close, kissing her hard, tongue pushing deep. Rachel kept pumping the strapon in and out of Dianes soaked cunt, the sound filthy and loud.
On your knees, Diane ordered when she broke the kiss. Suck your sisters cock while I watch.
Lisa dropped. Rachel pulled the dripping strapon free and fed it to her. Lisa opened wide and took the thick silicone into her mouth, tasting Dianes cream all over it. She sucked greedily, bobbing her head while Rachel held the back of her neck and fucked her throat.
Thats it, Rachel moaned. Get it nice and wet for Moms ass.
Diane stood, turned around, and bent over the arm of the couch. She reached back and spread her cheeks. Put it in my ass, Rachel. Then your sister can eat my pussy while you fuck me.
Rachel lined up and pushed the strapon into Dianes tight hole. Diane moaned low and filthy. Lisa crawled underneath, tongue out, licking Dianes swollen clit while the strapon stretched her ass open above her. The three of them moved together, raw and loud, the living room filling with wet slaps and desperate curses.
Diane came first, shaking and gushing down Lisas chin. Rachel didnt slow down. She kept pounding until Diane was begging, then pulled out and unbuckled the harness.
Your turn, she told Lisa, handing her the strapon. Fuck Moms ass while I sit on her face.
They switched places fast. Lisa strapped the harness on, the base pressing against her own clit. She shoved into Dianes stretched hole in one thrust. Diane cried out and buried her face between Rachels thighs, eating her stepdaughters pussy while Lisa railed her ass.
They didnt stop until all three were wrecked and shaking. Lisa pulled out, unbuckled, and collapsed onto the couch. Diane and Rachel curled against her, hands still roaming.
Diane kissed her neck. Welcome home, baby. Weve been saving that strapon for you all week.
Rachel laughed against her tits. Next round were both wearing one. Youre getting it from both ends.
Lisa smiled, already wet again. Im not going anywhere.
