Robert continued to hold the vibrator against Lexi's clit as he spanked her with the paddle, and she continued to squirm and cum, soaking the towel under her. Neither of them had noticed when the door opened slightly, and Mom peeked in. She was shocked by what she saw happening, but decided to watch for a bit before announcing her presence. Seeing her daughter being paddled by her stepfather was alarming, but as she watched, she could not deny a wetness growing in her pussy. She wanted to be angry, but instead she found herself getting turned on.
As Robert continued to assail Lexi and give her orgasm after orgasm with the vibrator and the paddle, Mom felt her wetness grow, her horniness overtook her thinking, and she had an idea... she'd join them! Unseen, she entered Lexi's room and found Robert's bag, searched it, and found a riding crop. She took the crop, slid next to Robert with a big smile on her face, and began to smack Lexi's rear. Robert turned in surprise and shock, and stopped paddling Lexi! Mom smiled at him and smacked Lexi's ass again with the crop. Robert saw that Mom was enjoying herself, so he resumed, and together they soon found a rhythm to their strikes on Lexi's ass.
Lexi was not in a good position to look back to see what was happening, but she felt the change when Mom started cropping her. Between them, the strikes on her rear were doubled, but the pain was not a problem while Lexi was so incredibly turned on.
Then she heard Mom say, "Let's stop now."
And Robert answered, "Okay."
Lexi was shocked to hear her Mom's voice and turned to see her. Mom smiled at her, and Lexi wasn't sure what to do.
"Just a minute," Robert said, and then undid the lashes that were holding Lexi.
Lexi got up and quickly put her pajamas back on. She looked at Robert, who seemed to be okay with what was happening. Then she looked at her Mom, who was still smiling.
"Well, I think we'll have some things to talk about tomorrow," Mom said to them both, and then she left the room.
"I think I'd better go now, too," Robert told Lexi, and then he left.
Lexi was confused, but also so turned on she couldn't sleep like this, so she fingered herself to an orgasm before going to sleep. She assumed Mom and Robert would be fucking in their room.

Lexi worried about breakfast the next day. Mom might be angry about finding her stepdad with her, and having sex, no less. But Mom was smiling last night, and she didn't understand why.
When Robert walked in, he said Mom wanted to talk to them together, but that she seemed okay about last night.
Shortly afterward, Mom came to the kitchen. She did not look unhappy, and Robert and Lexi were glad to see that.
"Well," Mom started, "I guess I'm the aggrieved party here, so I've decided that this situation will be settled on my terms. Now, we can do this the easy way, or we can do this the hard way."
"The hard way looks like this," she continued. "I would divorce Robert, and Lexi, you're an adult, so you'd have to move out of the house immediately."
Robert and Lexi both looked quite unhappy on hearing about the 'hard' way.
"But I don't want that, so let's look at the easy way," Mom continued.
"The main thing I want to say is that I want 'IN' on the little 'play time' thing you've got going. I always felt trapped in my first marriage, and seeing you two being kinky and having sex leads me to believe I don't have to feel trapped in this marriage, do I, Robert?"
"Ah, no," answered Robert.
"Good. So here's how it's going to be," Mom resumed. "Once a week, you two may continue your rendezvous in Lexi's room, with my blessing," Mom stated, "and once a week, we'll do a threesome in our bedroom.... I will call the shots, however. And if either of you cheats on the deal, we'll go back to the hard way. Do you both agree?"
"Yes," they both said, almost in sync.
"Okay, then we'll have our first threesome tonight at midnight."
o o o
That evening, Saturday night at exactly twelve o'clock, Lexi knocked on Mom and Robert's bedroom door, as ordered.
"Come in," Mom called.
Lexi went in and found Mom and Robert naked and waiting on the bed.
"Take your pajamas off, Lexi," Mom said, and Lexi obeyed.
"Tonight, Robert will fuck you, Lexi, while he's eating my pussy. Robert, on your back on the bed. Lexi, you mount him cowboy style, facing his head, where I will be kneeling so he can eat me."
Robert lay on the bed as he was told to, and Lexi climbed onto him, facing his head and straddling him, resting on her knees. She lined her pussy up with his erect cock and slid onto him. She was so turned on by the thought of fucking him that she easily took his length into her and sat resting on his hips, completely impaled. Meanwhile, Mom knelt, straddling his head, and positioned her cunt over his mouth. Lexi began to lift up and then let herself down on Robert's cock, fucking him as he lay, and he responded by thrusting upward in sync with her. Lexi's pussy was sopping wet from her arousal, and she loved that Mom saw fit to let them have sex, and not end everything that she and Robert had started. These threesome sessions were a diversion, but they could be fun too, she thought.
While Lexi was fucking Robert, Mom knelt over his mouth, facing away from Lexi. She lowered her pussy to his mouth, and he began to lick her. She jerked as his tongue teased her silt, licking her up and down. And she squirmed with pleasure when he licked over her clit, rubbing her cunt into his mouth. She was clearly enjoying her role and having things her way when Robert's tongue hit a nerve in her clit, and she jumped with pleasure and moaned loudly. Both Robert and Lexi were pleased to hear her while they fucked on.
The three of them continued to please one another. Robert was getting close to cumming in Lexi's cunt, and she was rocking atop him with his cock drilling her while Mom was clearly enjoying Robert's licking of her clit and darting his tongue in and out of her vagina, when Mom suddenly spoke.
"Alright, switch positions!" she exclaimed. "I'll mount Robert's cock, and Lexi will sit on his face."
It was hard, but they stopped what they were doing, and Lexi got off Robert, dripping some of her juices as she did. Mom then straddled Robert and impaled herself on his cock, while Lexi moved to Robert's head and put her knees on either side of him, then lowered her pussy to his mouth. Mom rocked on top of Robert, driving his erection to the hilt, buried in her cunt, while Lexi felt him lapping up her nectar and teasing her slit.
It didn't take long before all three of them were totally aroused again, but it was Robert who lost it first. He jerked and spasmed and came in Mom as she leaned over him; she felt his warmth explode into her. That triggered Mom's orgasm, and she came hard, jerking as she screamed out in pleasure, flooding Robert with her juices. Last was Lexi, who was enjoying Robert's tongue as he teased her pussy. When Mom's orgasm subsided, she reached around Lexi and grabbed her nipples, pinching them as hard as she could. Lexi jumped in pain, but it put her over the edge as she came on Robert's face, gushing her nectar over his lips. All three of them let go of their pent-up sexual desires and enjoyed cumming on and in one another.
o o o
Mom decided that Robert and Lexi would be allowed to have Thursday nights, and only Thursday nights, for their fun, that Saturdays would be reserved for their threesomes, that Mom could request an added threesome any time without warning, and that there would be no changes to the schedule without her okay. They agreed.
So the next Thursday, Robert arrived at Lexi's door at midnight as scheduled, and she let him in. He had his carry bag with him.
"This seems weird," he told her, "with Mom calling all the shots. But at least she didn't divorce me and throw you out. We should be thankful and enjoy ourselves as we did before. I'm happy to see you naked and waiting just like you did before. Are you okay with acting as if nothing has changed?"
"Yes, Daddy. From now on, when you come in here on Thursdays, it will be the same as before. You're still my master, and I'm still your slut!"
"Right. So let's get to it, shall we?"
"Okay, Master."
"On the bed on your hands and knees, slut, and spread your legs! Do you remember your safe word?"
"Yes," Lexi replied as she immediately got on her hands and knees.
Robert grabbed the riding crop from the bag and slapped her rear with it. Lexi jumped and squealed a little at the sudden pain, but was fine. Slapping harder with each smack, Robert continued. Lexi felt the sting of each strike, but also the turn on that accompanied it. She had grown to love being spanked, whether by hand or device, and the pain always turned to arousal quickly.
Lexi squirmed as Robert spanked her rear, and jerked when he began to smack her pussy with upward strikes of the crop between her spread legs. She started to leak her juices as he continued to spank her cunt, hitting her slit and clit with stinging blows. Every strike hurt, but also triggered her arousal, and she was squirming in pleasure. She had trouble staying upright as each hit made her jerk forward, so Robert stopped.
"I see we'll need to restrain you before we continue," he said matter-of-factly, "so lie on your back."
Lexi immediately obeyed.
Robert took lashes and rope from his bag and fastened her wrists and ankles to the corners of the bed, and added a hand towel in her mouth to muffle her. With Lexi spread and helpless, he resumed cropping her cunt. Strike after strike found its target as he gave Lexi all she could take. She squirmed and screamed out, but the towel in her mouth quieted her. She was unable to use her safe word now, even if she wanted to. Meanwhile, Robert continued to spank her cunt with the riding crop, and Lexi absorbed the pain as she was completely turned on.
Realizing she was ready, he stopped cropping her and brought out a vibrator. He placed it on her exposed pussy and turned it on high. She immediately jumped at the instant pleasure it provided, and squirmed as much as she could, but Robert did not let up. In no time, Lexi came. She gushed her nectar profusely, soaking her sheet and jerking wildly as her orgasm hit, but he continued to buzz her. Lexi's orgasms hit her in quick succession, and she came repeatedly. She rocked her hips back and forth and tried to move her legs, but they were pulled tight and she could not. She continued to spasm and cum, over and over. She tried to scream from the overload of sensations hitting her, but the towel muffled her voice, and Robert kept the vibrator on her clit. She was wearing out quickly.
Finally, Robert stopped the vibrator. Lexi was sore and exhausted from countless orgasms, but he was not done with her yet. He climbed on the bed and placed his erect cock at her pussy. After teasing her with it for a moment, he pressed into her vagina and drilled deep. He hit her cervix in short order, and she screamed out to no avail. Lexi had nothing left after the overload of orgasms, so Robert just fucked her at his pace. He sped up when he got close to his climax, then shot his load into her, squirt after squirt. When he was done, he simply pulled out.
He took the towel from her mouth and undid the lashes that held her down. She was relieved to be free, and to be able to exhale through her mouth after the intense orgasmic session she'd experienced. He cleaned up and put his pajamas back on, then put the toys back in his bag, kissed her on the lips, and left. Lexi wiped her pussy dry, put on her pajamas, and fell asleep quickly.
o o o
And so it continued week after week. On Thursdays, Robert went to Lexi's room and tormented her before fucking her senseless. And on Saturdays, Lexi went to Mom's room to have a threesome with them. The sessions in Mom's room took on a more BDSM-like tone over time, as Mom joined Robert in inflicting various torments on Lexi to turn her on before they fucked her in whatever way pleased Mom.
A typical threesome usually started with a spanking, which progressed to tying Lexi down on the bed or to a bench or chair. One of Mom's favorite ways was to tie Lexi to an armless wooden chair, with Lexi kneeling on the seat and facing the chair's back. Then Robert would tie her to the chair, her arms tied to the top of the back, her head resting on her arms, and her ass hanging off the seat a bit. In that position, Mom and Robert had unfettered access to Lexi's ass, cunt, and breasts, and they used all three to arouse Lexi to a climax.
Mom let Robert work on her ass while she went after her tits. So, Robert spanked her rear for a while with one of the paddles, crops, or floggers from the bag, while Mom placed a set of her nipple clamps on Lexi and pulled on the chain to stretch her nipples and breasts. Lexi got a twofold torment as they worked in tandem to inflict pain on her. Both her nipples and ass hurt as they made sure that they would, but all three of them knew the pain would quickly arouse Lexi.
Once they got Lexi turned on, they would untie her from the chair and take her to the bed, where Mom and Lexi would both kneel side-by-side at the edge with their rears facing out. Then Robert would take turns driving his erection into them from behind, sometimes into their vaginas and sometimes with lube into their assholes, always accompanied by his hands on their pussies and nipples to drive them wild.
He would switch back and forth every minute as he fucked them both, and they would both moan and squirm as he did. By arousing their clits and nipples, they would almost always cum before he did. If not, he'd just take them to an orgasm with his hands still on their nipples and fingers on their clits. It worked so well that this became another of Mom's favorite threesome sexcapades, and she called for it frequently.
o o o
With their newfound sexual arrangement, Mom, Robert, and Lexi had wonderful sex every Saturday, and Robert and Lexi got what they wanted as a couple on Thursdays. Mom called the shots, but all three enjoyed the arrangement, adding new wrinkles often, and all of them got what they desired.
