I reached beneath the robes and fumbled for the clasp on the ball gag.
"You bastard," she spat out.
I said nothing.
"If you wanted to play a game, you could have asked. If it wasn't for that orgasm, I'd be going to the cops right now, I guess its lucky for us both you know how to fuck me." Kath blurted out breathlessly.
I knelt down next to her and stroked her buttock, she giggled as my caress tickled her.
"Don't stop there," she teased.
And with that I reached down to her side draw and pulled out her favourite vibrator. Switching it on I began to massage her clit and she gasped and squirmed beneath its attention. Glancing back at her phone I could see I had a few minutes to play with her before John would arrive. Her squirming continued as I pressed the head of the vibrator hard against her engorged clitoris, flicking her clit from side to side with the device and drawing more breathless groans. After I few minutes I stopped.
"John, you'd better untie me, or finish what you started, I need to cum again." Pleaded Kath's voice.
But I was already putting the vibrator away and reaching inside the robes to tighten the clasp of the ball gag again. Once it was secure and Kath was reduced to unintelligible sounds again, I made plenty of noise leaving the room and making my way down into the kitchen. I made enough noise that she would think a glass of water was being drunk and pulled a chair across the stone floor as if John was taking a breather.
I quietly opened the external door and snuck back upstairs, silently opening the mirrored wardrobe door and climbing inside, sliding it closed behind me but leaving a crack through which I could see my wife's pale buttocks and long legs spreadeagled before me. She had quite a surprise on its way, and I wanted a front row seat for this.
I heard John's footsteps downstairs at first and then on the stairway as he made his way into the room.
True to the instructions, he undressed, and stood at the foot of the bed, wordlessly looking down at my wife's supine body, prepared for him, with the butt-plug handle pointing invitingly at his already hard cock. He was smiling and with a lick of his lips he knelt behind her on the bed.
This provoked Kath to move her head, listening intently to the movement behind her. As John's fingers rested on the handle of the plug she began to move wildly beneath the robes, his smile widened and he slid the device from her, placing it down beside him. Picking up the lube he added a generous amount to both her slightly gaping hole and his large cock. Leaning forward he placed it at the entrance to her virginal asshole and paused. The wild movement beneath him as my wife writhed at the attention of her ass stopped him.
He then reached below with his hand down to her pussy. Kath squealed. He had pinched her clitoris, and hard. He did it again and as she squeezed the sheets tight in her fingers he lunged forward, pressing himself into her new pleasure hole until a popping motion and Kath's renewed squealing heralded his entry to her asshole.
"Nnnnnnnnnnnnnnnnnnnn," she screeched into the gag, and I imagined her biting the ball in her mouth as her ass squeezed tight around the engorged length inside her.
With just the head of his cock inside, he pushed himself up and grabbed her hips, bringing her ass up so he could fuck her kneeling. He paused, looking down at the creamy pastel orbs of her ass, and admiring the sight of his thick cock teasing her asshole with its first inch. Slowly he slid himself into her, inch by inch, maintaining a firm grip on her so, try as she might, she couldn't wriggle off him. As he pushed the first few inches of his cock in, she arched her back to ease the intrusion, and I could imagine her face beneath the robes, eyes tight shut, and mouth slightly agape as his cock filled her hole, no doubt she was glad of the plug now, having prepared her for the entry of this large cock.
He had pushed the robes higher and was reaching forward to cup her heaving breasts, his fingers dug deep into their fullness, her hard nipples poking out between his fingers. I was harder than ever and couldn't my eyes off the huge thing impaling my wife.
Her body trembled with his thrusts, after the first minute or so the entire length of his rigid cock was disappearing up my wife's ass and heavy panting had replaced her squeals of earlier. Her back hollowed to accept him inside her, his hands grasped the whiteness of her ass, spreading it wide and making it easier for me to see the action. After several minutes of pounding, he became animalistic, pounding her with urgency as the disciplined strokes he began with gave way to his lust. Kath moaned and her breasts swung freely beneath her, rocking with his thrusts and heaving with her uncontrolled breathing.
With a final thrust he erupted inside her, hanging onto her ass as he penetrated her deeply, filling her bowels with ropes of cum. Kath meanwhile moaned into her gag, her whole body shaking with the force of his orgasm, and deep inhalations in her robed prison.
John slid out of her quickly, rope of cum leaving her ass and dripping onto the sheets below, with a groan she slumped down as his subsiding erection bobbed above her. He stared down at her cum soaked holes, reviewing his mornings work.
With a last grin at her exhausted form, he stepped off the bed and dressed quickly to the sounds of Kath's exhausted breathing. He said nothing as he left the room and as soon as he began down the stairs I slipped from my hiding place and opened one of the Velcro cords binding her to the bed.
Turning and stepping quietly out of the room I could hear the sound of Velcro opening and as quietly as possible I stepped out of the front door. John's car was leaving, and I waited ten minutes before making my 'official arrival.'
I knocked on the door and leaned down to the mailbox opening.
"Hello, I'm home," I announced, can you let me in? I've left my keys on the ship." I lied.
Kath came down the stairs, with her bath robes tied at the front, she looked red eyed and tired. She opened the door and embraced me, her arms around me warmer than I expected.
I looked down and kissed her deeply.
"I've been fantasising about you all the way here, I meant to surprise you, but I forgot my keys," I explained.
"Oh sweetie, I'd have loved that," said Kath.
"Well, I'm here now," I said with a grin, my cock hardening at the thought of the fun I'd have with her.
I followed her into the kitchen gazing at the plumpness of her ass beneath the robes, she'd managed to straighten herself up before I arrived, and her hair was neatly combed. It hadn't taken her long to get over the ordeal.
She reached up to open a cupboard and I rushed behind her to grab her hips and kiss her neck.
"Not here," she implored, glancing toward the door, I ignored her false prudishness and ground my stiffening cock hard into her buttocks, kissing her deeply. Reaching forward I slipped my hand inside her robes.
"You're wet already," I said, "you're hornier than I am."
