The New Normal
It was two weeks after the family decision to add sex to their intra-family relationships. Before the first week of their new arrangement was over, Kris and Karla were each sleeping with their mother three nights a week not counting Sunday night, when they both shared their mother's bed. During the first week, there was a lot of sexual contact outside of the bedroom as they all enjoyed taking every opportunity to touch each other. By the end of the second week, the entire plan fell apart.
It started when Kris and Karla decided they wanted to sleep together without involving their mother. The twins wanted some time alone together to experiment and be more intimate with each other without the distraction of their mother in bed with them. Lena was surprisingly accepting of their idea to sleep together in one of their own beds instead of hers on a Sunday night.
"Frankly, I could use a night to myself to recover. You two have been wearing me out," she chuckled.
Lena ordered additional security cameras for their home system to cover every room in the house, including the two bathrooms. She had Kris fashion a lens cover for each camera using black electrical tape that could be lifted clear to allow viewing inside the room, or put down over the lens to prevent outside viewing of what was going on inside.
Despite their initial trepidation, both Kris and his sister quickly stopped caring if someone was watching them. This was largely due to the amount of time they were already spending with each other in very intimate activities, and the very relaxed atmosphere that permeated the house. During most mornings and evenings when they weren't dressed for work or any other outside activity, they all tended to wear very little clothing. Lena spent most mornings wearing one of her nightgowns or just a long t-shirt, even though she always slept nude. Karla also wore just a long t-shirt and sometimes a thong, while Kris usually wore his boxer shorts and a t-shirt.
After the first month of everyone sleeping together and having sex nearly every night, the novelty of their situation wore off and evening sleeping arrangements became more ad hoc. The sex also slowed down, but not by much. This occurred with unexpectedly little friction. Each adult discovered the benefits of regular time off to rest and recover from what had become a highly sexual environment. Their new openness led to a household of almost constant near-nudity, which turned out to be more stimulating and erotic than if they all just abandoned clothes completely while indoors.
In fairness, their limited clothing style resulted more from laziness than any intent to be sexually provocative. The bare concealment offered by what they did wear in an attempt towards some sort of modesty backfired and ended up accentuating the physical delights that were more than hinted at beneath the scant outerwear.
The first few times that two of the three asked to spend the evening alone together were awkward. However, as they all grew more comfortable with their arrangements and no one felt they were being unfairly treated or ignored, it became easier to discuss and plan. The third person who was spending the evening sleeping alone always had the option to view the couple on one of the webcams, but Karla and her mother were the only two who seemed to really enjoy voyeurism.
Karla did tell Kris about her two "girlfriends" and their arrangement. Kris was surprised by his sister's admission, but was supportive of her right to choose how she wanted to live her sex life and with whom she wanted to share herself. The first afternoon that she brought Melissa to their home for some afternoon delight, Kris and his mother remained discreetly away to give the two young women some privacy. Even though Karla completely forgot about covering the camera lens, Kris and Lena never tried to look in on them.
That evening in bed together, Karla confided to her brother that Melissa thought he was really cute and that she was interested in going out on a date with him.
"Wouldn't that be kinda awkward?" Kris responded. "I mean, what if we got serious and stuff?" Karla knew exactly what kind of "stuff" her brother was talking about.
"Nope, not at all. I already told you that Melissa, Jenna, and I are in our own kind of open relationship and we have never had any issues with jealousy or anything. Just ask her out and get to know her. I think you two have a lot in common, anyway."
Karla also spent a lot more time talking to her mother and one afternoon, they took off together for a shopping trip. When Kris joined Karla for their evening shower together, he found out the two women went to a spa to have themselves waxed from their pussy to their ass. Later that evening in bed with both of them, he quickly decided that their new look was definitely more enjoyable.
Lena met with her gynecologist the first week after she started sleeping with her son and was given a prescription for birth control pills. After a month, Kris was able to stop buying boxes of condoms each week to have intercourse with his mother. Karla had been on birth control pills since starting high school to help regulate her period and reduce the severity of her menstrual cramps. Kris always noted a distinct reduction in sensitivity of his cock when he used a condom to fuck his mother as compared to going bareback to fuck his sister.
Lena managed to convince Karla to experiment with anal sex and then spent a week using a set of butt plugs to help train her daughter's virginal ass. Following that initial period, Lena began spending some time each day helping to stretch her daughter's ass even more so that she wouldn't feel any pain or discomfort when her brother first entered her ass. Kris found the whole thing a little amusing, but always declined his mother and sister's entreaties to let them work on his ass the same way. While Karla was experimenting with anal sex, she still wasn't ready to let her brother fuck her ass. He often fingered it, especially when eating out her pussy, but that was the extent of anal sex that she enjoyed with him. Everything else she did with her mother, including her first foray into performing analingus on her mother. Watching from the sidelines, Kris secretly began to wonder what it felt like and eventually, managed to discreetly "borrow" the butt plugs to try on himself when his sister no longer required them.
The smallest of the three plugs slipped up his ass pretty easily after being well-lubricated with gel. He tried the next two sizes in quick succession and didn't find anything painful or uncomfortable about having his butt hole plugged. The largest of the three plugs was 1-¼ inches wide at the base and usually only caused minor discomfort for a few minutes after initial insertion. Less than a week later, he could insert that plug without any preparation other than smearing it with lubricant, and it felt completely comfortable. After that, he even went around for half the day with the largest plug up inside his ass just to see what it was like, and afterwards, he grew interested in trying something designed to be more anally stimulating and potentially wider.
That led him to buy anal toys made specifically for men and try them out in private. His favorite was a large weighted plug that he would wear for a few hours at a time. Part of his excitement was due to being anally stimulated while nobody around him knew about it. He also had a vibrating butt plug, but only used it in private because the humming noise was quite noticeable. The more he experimented, the bolder he became and soon, he had a sizable collection of anal toys in his bedroom. However, his secret quickly came out.
Throughout his furtive anal sex play "research", Kris forgot about the security cameras. His mother and sister separately spotted him placing something up inside his ass at different times. Both were surprised, but neither mentioned what they saw either to Kris or each other. However, the women's interests were piqued and they started calling up the security cam in Kris' room more frequently when he was home to learn more about what he was up to.
This continued for nearly a month while his toy collection grew along with his curiosity. One night, while Kris was on a date with Melissa, Karla and her mother were laying alone together after a prolonged and gentle love-making session that also happened to involve anal play between the women. Karla broached the topic first, unsure of exactly what to say, but confident that her mother would be understanding, especially towards Kris.
"Mom?" she whispered. "Have you noticed Kris acting differently recently?" she whispered.
"Mmm..no. Acting differently how?" Lena replied equally quietly.
"I dunno. He spends more time alone in his room than he used to," Karla explained.
