I was hard again, and Barb was clutching wildly at the bed sheets. Karen had her face firmly planted in the younger one's bush. Her hands gripped hard into Barb's ass, leaving deep indentations in her flesh. Karen's loud, sucking kisses and licks sounded like wet slaps of a sponge against a tub full of water, but they were almost drowned out by Barb's throaty moans.
Barb lewdly jacked up her ass ever higher into the air, I suspect in response to Karen's rough nibbling to her clitoris. A large, open-mouth grin lit across her face, as she blurted out, "Oh my god...Mistress...That's the spo...ot..."
Momentarily spent, Barb laid her head down in absolute sated bliss. Karen lifted hers up with a smile. She kissed each of Barb's ass cheeks lovingly, saying, "Oh, little one, Sir and I haven't even started touching the spot. Now where did I put that lube...Ah, here it is. Now, just stay as you are and I'll get you all ready for the main event."
Barbara was still panting, breathless, and continued spreading her cheeks wide for Karen with both hands. Karen squeezed a liberal amount of lubricant down her cleft. The cool temperature of the substance on her overly heated and overly sensitive vitals caused Barb to gasp and clench her buttocks. Putting a soothing hand on the small of her back, Karen worked a finger around Barb's anus, then pushed in ever so slowly.
Barb inexplicably broke with protocol, "What's going to be this 'main event' you keep..."
She didn't finish as Karen slapped her ass. Tears immediately erupted from Barb's eyes. Karen slid up close to her ear, and hissed like a viper ready to strike, "Did either of us say you could talk? You didn't even address us properly, speaking to us as if we were your parents and you were some snotty, little, teenage whore."
"I'm sorry, Mistress."
"I knew I would be able to use that last slap. You unruly little sluts never can keep quiet." Karen slipped her finger back into Barbara's asshole, while asking, "You think you can stay a good little slut for Mistress and Sir?"
"Yes, Mistress."
"Now, if you really want to know what's going to happen to you, then maybe Sir will tell you."
Karen went back behind Barbara, and continued to prepare her. Barb looked up at me with a questioning eye. I smiled down at her and caressed her cheek, and said, "I think I'll keep it a surprise. You'll find out soon enough. And no more speaking out of turn, or I'll be the one administering the punishment."
By now, Karen had pushed in a second finger, and worked both around together until her hand was flush with Barb's ass.
Karen gave a lighter spank to Barb—I guess she couldn't help herself—then kissed the spot she just smacked.
"Does this feel good, dear heart?"
"Oh yes, Mistress!"
Karen pulled her fingers out, and said to me, "I think she's ready, Sir."
I looked down at Barb and stroked her cheek soothingly, while answering Karen, "Let's do this one at a time to start. I want to make this as enjoyable as possible for her. You should see to your end first before I join you."
Karen squeezed more lubricant on Barb and applied a healthy amount to the strap-on. Once she lined the strap-on up in her asshole, Karen grabbed Barb by the hips and slowly inch her way in.
Barb gasped at the initial surge of pain, and instinctively flinched away from Karen, but Karen held her fast, saying, "It will hurt at the start, dear heart, but I'll be gentle. Soon, though, you'll be thanking Mistress for the pleasure."
Karen was gentle with her. After pushing in a little bit, she held herself still so that Barb could get used to the girth. Occasionally, she would pull out altogether, and rub Barb's clit—providing pleasure to compliment the pain. She squirted a bit more lube into Barb's hole, and slid back in to the point she was before.
I watched Barb's face through all of this. So far, she couldn't hide from me the pain that she was feeling, as she scrunched up her face, tightly closing her lips and eyes to the hurt. Small tears were squeezed out and ran down her cheeks. As I watched her face, I thought maybe I should have been the one entering her. At least I would have a better feel for the resistance I would meet compared to Karen with a strap-on. I discarded that idea, however. I would have been too big for her as a first time.
All of a sudden, her sphincter must have relaxed, because a sudden calm washed over her face. Karen found the slide easier the rest of the way, and parked herself flush against Barbara's ass. Next, Karen rocked herself gently, working the strap-on around a little bit at a time to loosen Barb's sphincter further. Her rocking soon gave way to long, slow glides, pulling almost all the way out then pushing all the way in again. She pulled out, and again squirted more lube in into her hole—just to be safe. When she reentered, Karen's gliding become quicker. Barb's face blossomed into a wonderfully, blissful mask, while small, subtle moans escaped from trembling lips.
Karen pulled out again, and asked, "Anything to say, dear heart?"
"Thank you, Mistress," she responded, panting.
Karen laughed, "Oh, the pleasure hasn't even started."
I pulled Barb up to me, and commanded, "Sit down facing me. Then slide my cock into your pussy."
When she sat fully down on me, I held her close and leaned back, giving Karen a nice, stationary, unobstructed target.
I felt the strap-on pushing past me, and pushing my cock hard against the dorsal wall of Barb's cunt. Barbara grunted a bit in pain, but when Karen slid fully inside of her and lightly tapping her pelvis against Barb's ass, I saw the pleasure flow across the young one's face.
Oh, it was all so tight in there, with my cock pressed firmly in her warm confines. I felt her muscles grip me as she clenched her buttocks tightly against the strap-on, and I felt the slow drip of her arousal tickling down my balls.
Based on the look on Barbara's face, I could tell this wasn't going to take too much time, but I so wanted to extend the moment. I kissed her gently on the lips, and commanded, "Mistress and I are going to stay still to start. We want you to fuck us all by your lonesome until you don't feel any pain. Go as slow or fast as you're comfortable with."
She moaned a, "Yes, Sir," then started shifting her hips slightly. Even with those small movements, I could feel the strap-on forcing my cock to and fro in her pussy, sending wonderful waves of pleasure down my shaft.
I heard a soft slap, as Karen spanked Barb's ass. She didn't say anything to Barb, but it acted like a signal from a rider to her mount—Barb quickened her hip shifting.
I could see the blissful climb toward climax expressed fully on her face. A fine sweat had already broken out along her forehead, neck, and chest. Her breathing came shallow and rapid through slightly parted lips, and every so often, her tongue would dart out, seductively, as she needed to moisten those lips against her drying breath. Her eyes, when they were opened, were full of expression as they stared at me; full of dreamy sex one minute, then acquiring an almost thoughtful glint the next as if she were contemplating the bliss Karen and I were promulgating within her. After each one of those smoky, thoughtful looks, her eyes would slowly close as another wave of euphoria ratcheted her arousal to a higher plateau.
I heard another spank, more forceful this time. At Karen's signal, Barb changed her tempo and technique, and began using her legs to softly slide up and down as she continued her rocking shift with her hips.
A large grin broke out across her face, as she grunted, "Fuck...Oh my...Fuck."
Her soft slide became a firm bounce. I watched, enthralled, as her firm tits bounced and jiggled seductively with her body's movements. She pushed them forward so that their hard nipples rubbed against my chest. That little action caused her areolas to swell and dimple, becoming as hardened disks against her softer, jiggling mounds. She took a hold of her tits and scraped her nipples and areolas lewdly against my own nipples, trying to garner every small pleasure she could from every erogenous zone. When I put a rough finger against her nipples, her body quivered in delight. She moaned, "Fuck...Oh my...Fuck," again.
I began my own short thrusting to compliment Barbara's bounce, and Karen quickly followed suite with her own shifting. It wasn't long before Barb stopped her bouncing, letting Karen and I thrust into her on our own accord. Her face was calm, eyes closed but mouth agape, as she concentrated on the ever increasing euphoric waves. She still held her breasts in each hand, and kneaded them roughly, as she requested, "Suck on my tits, please Sir."
At the moment I set my mouth to them, I heard another loud smack. Barbara yelped loudly, but it wasn't from the pain. I felt a small flood of her ejaculate trickle into my lap.
Thinking that she had come and it was over, I began to slow my thrusting, but she pleaded earnestly, yet softly, "Please fuck me harder, Sir...Fuck me harder...Oh, fuck me harder!"
There was another loud spank, and I felt another small flood of fluid. Barbara began to yell, over and over, "Oh my god!"
Karen spanked her again. This time she wound up both hands and belted Barbara roughly into both her ass cheeks. The sound of the contact was as loud and sharp as a whip cracking. Instantly, I felt a heavier flow released from her this time. Barbara screamed abruptly, and it was quickly followed by loud chanting, "Harder, please Sir, Mistress. Harder...Harder...Harder...!"
Karen and I slammed into her with abandon. Sweat began to pour off all our faces. I wondered how long this could go on. Barbara already had three little orgasms, and continued to ramp up to an even higher plateau of ecstasy after each one. I started to wonder if I was somehow influencing even this aspect of her sexuality.
