"Oh God That's Deep!" Beth moaned as she rode your cock, you couldn't do anything but watch her now that your mom had taken off the eye mask but kept the O-ring in your mouth, you watched as you sister rode your cock, and your mom sat behind her playing with her smaller breasts as she did.

"That's it sweetie, ride him like you own him. Own your brother Beth, tell him who's in charge" your mom purred as she kept playing with Beth's breasts as she moved faster and moaned louder, getting closer to cumming. So were you, her pussy so tight it felt like a vice on your cock "Show him he has to please his Mistress"

"Damn that's hot" Beth moaned as she leaned back into her mom "I want it, I wanna own this cock too, I wanna own him!"

"Then do it, fuck your brother and cum from his big cock deep in your tight pussy, own him"

Leaning forwards Beth's face hovered above yours, the lust driven look in her eyes making her look slightly crazy as she didn't slow down riding your dick, just slamming down on it harder. Her hands moving to your throat and gently squeezing to show you she had full control

"Hear that Brian? I own this cock now, I own you. When I want to fuck, we fuck. When I want you to lick my holes, you're gonna do it no matter where we are. If I want to pimp you out to my friends and they want to do the nastiest, dirtiest shit to you, you'll say thank you and take it like the bitch you are, got it"

Not actually able to say anything, you just let out a grunt and gave a nod, Beth smiling and giving you gentle slap across the face

"That's right, you know where you belong now. Time to make me cum"

Leaning back Beth started riding you faster and harder, moaning louder as her mom started to play with her tits again, slamming down onto you over and over as she got closer and closer to cumming. You wanted to grab her, pull her down onto you yourself but even as you pulled against your restraints you knew you weren't going anywhere, all you could do was push your hips into her, trying to keep pace with her ever-erratic pounding.

"That's good, so fucking good" Beth moaned as she looked back at her mom "I'm cumming, I'm cumming mommy"

"Do it baby, cum from that big dick" Your mom purred as she kissed your sister, who moaned loudly as you felt her squeeze tight around your dick, making you moan as well, both you and your sister cumming at the same time, unable to stop yourself from watching your two new mistresses from making out as you filled Beth up with your cum.

"I feel so full" Beth purred as she finally broke the kiss, lifting herself up and off you as your dick slowly pulled out of her "I came so hard"

"Feel good, doesn't it?" your mom asked as she stroked Beth's hair, both of them ignoring you for now "we'll have to get you on the pill, if you want to keep fucking that dick"

"Mm, I do mommy, I want it all the time" Beth giggled as she looked at your still semi-hard cock

"I know sweetie, but for now we all need to get cleaned up before your father gets home, and I dare say Brian needs a break." Giving Beth one last kiss, your mom and sister started undoing your bindings, letting you sit up and massaging your wrists and ankles as you took out the ring gag "Now what do you say?" she asked you

"... Thank you Mistress, and Mistress" you mumbled, your jaw and tongue feeling tired and sore after a long day"

"Actually, call me Princess" Beth smiled as she looked down at you and your semi-hard cock. Turning her back to you she bent over slightly, her ass sticking out to you as she looked over her shoulder "Crawl over here and say 'Thank you Princess Beth' and give me a nice big kiss" she said as she gave her ass a gentle tap to tell you where to kiss.

Glancing at your mom, and not wanting to know what punishment these two would give you for disobeying them you moved onto your hands and knees and crawl to the end of the bed where Beth stood, and leaning in gave her ass cheek as kiss "Thank you Princess Beth"

"Don't forget to thank me too" Your mom laughed as she showed her ass to you, blushing slightly you moved to her and kissed her ass cheek as well. "Good boy, now go get cleaned up while I talk to Beth about her little idea earlier, I know some lonely ladies who'd enjoy your company"

Climbing off the bed you headed to the bathroom to grab a shower, and get the days funk off you, leaving your mother and sister to scheme behind your back.
