With Adela on top

Adela holds up her strap-on. "Well, first you'll need this."

"Oh. Right."

Grace takes the strap-on from Adela, who then walks up to you. "Hmm. Now how do I want you, my Pet?"

Adela taps her finger on her chin as the gears in her mind grinding. By the time Grace has taken her pants off and put 'cock' on, Adela is giving you a wicked grin that has you both excited and fearful.

"Okay Grace, lube that cock up."

"Uhh, how much do I use?"

"The more the better."

"Got it."

As Grace drenches the strap-on in lube, Adela says "Now stick your legs up in the air Pet."

You do just that.

"As far back as they can go, Pet."

"Yes my Queen."

Pulling your knees towards your chest, you roll your hips back, making sure to stick your ass in the air for your Mistress. Said Mistress then gets on the bed and moves on top of you. Whilst she pours lube onto your hole, your Queen grips your cock with one hand before using the other to spread lube around your entrance. Mistress Grace then asks "Think he's ready Queen?"

"I think so. Are you ready Pet?"

"Yes my Queen."

"Okay. Go slow Grace."

"I will."

Grace moves towards you and presses the tip against your hole. With a deep breath, she makes a gentle entrance, to which you moan and Adela says "That's it. Nice and slow."

"Ahh..." You coo.

Adela looks to you. "That good Pet?"

"Yes my Queen."

"What do you say?"

You look up to Grace and say "Thank you Mistress Grace."

"No problem, Pet."

She starts to piston you at a timid pace, adjusting to the new rhythm. With every thrust, she inches the strap-on deeper, making it rub against your prostate. Your loud moans fill the room as your Queen strokes your cock. She watches Grace get into a steady rhythm that has you singing with pleasure. Your new mistress seems to excel in her new role.

"Oh that's it Grace. Fuck his little hole." Your Queen says.

"Can I go a bit faster?" Mistress Grace asks.

"Not yet. Just like that for now."

Adela then gets onto the bed, and moves on top of you, facing Grace. As your cock meets with the lips of her entrance, she says "You know I get so little of this cock now."

"Why? Because Pet enjoys being ass fucked?" Grace growls.

"Pretty much, don't ya Butt Slut."

"Ahh... Yes my Queen." You cry.

Adela then lowers herself down your length, moaning as her wetness consumed your cock. Adela proceeded to work your cock as Grace continued to plow you. The combination of sensations becomes more intoxicating as Adela rides your cock harder. Grace follows her lead and starts drilling you faster. Both sensations have your balls tightening.

"Ohh fuck... I'm gonna cum."

"Ah... Not yet Pet." Adela growls, right as you erupt inside of her.

Now spent, you flop down on the bed and mutter "I'm sorry my Queen."

Adela slides off of your shaft and then cocks her head towards you. "That's okay Pet. I'll just have to come up with a way to punish you."
