The SM affair between wife Xiaoling and her sister (Part 6)

The sisters began to release their sexuality in the second SM stress relief meeting

————————————————

Finally, it's the Sunday everyone is looking forward to, the SM de-stressing party.

I spent the whole afternoon in the audio-visual control room preparing for the entire SM decompression meeting in the evening.

My wife went to the gym with her sisters to swim and then had dinner before returning home at around 7 o'clock.

As soon as I got home, my wife asked me to put on a Lycra-coated Superman suit and a Superman mask and be responsible for receiving guests.

In fact, I just put on a transparent resin ring chastity belt for everyone to confirm and then lock it to prevent me from having any bad intentions.

Because I was wearing a superhero costume and a mask, the sisters didn't see my face, which saved everyone from embarrassment.

In fact, even if the wife didn't tell everyone, everyone knew who the man serving them tonight was, but everyone was tactful and didn't say it.

It might be my illusion, but I found that Xiaoyu and Xiaoli seemed to take a few more glances at my genitals with the chastity belt on.

After everyone confirmed that my chastity belt was safe, my wife asked me to go to the audio-visual control room and wait.

After I entered the audio-visual control room in the SM training room, my wife and sisters began to enter the SM training room.

I dimmed the lights in the SM tutorial to avoid being shy because of the bright lights, and then played soft music with the lights.

I didn't notice it just now, but now I see from the camera that my wife and her sisters went swimming and eating in the afternoon. They all seemed to be wearing cool and sexy clothes.

Under the temptation of lights and music, my wife and sisters have begun to take off their clothes to expose themselves naked

Except for Xiaorong who was a little shy, the other women took off their clothes generously to show off their sexy bodies.

Xiaorong may not be wearing a one-piece vest today because she is going swimming. She is wearing a set of three-quarter cup pink lace underwear.

The breasts exposed above the bra fully show her beautiful 33C breast shape, which is impressive. It seems that Xiaorong is becoming more and more open.

Xiaoli was wearing a thin piece of cloth tied with a silver shiny bikini, the cloth barely covered her nipples, areola and labia.

If you look closely, you can see that Xiaoli's nipples and clitoris are bulging. This outfit is simply designed to seduce men.

Xiaoyu generously showed off her figure, her black leather bra and panties were full of wild beauty, and her 34D big breasts were breathtaking.

My wife is wearing a sexy bikini with a zipper and a crotchless design. Although her breasts are only 32B, they stand proudly.

These women seem to care less and less about being exposed or being watched. They all try their best to show off their feminine charm. Who are they trying to seduce?

Then everyone started to pick up the Lycra gel coats they had tried on and put them on. I saw that Xiaorong seemed to be more natural after putting them on.

Today, everyone chose to wear headgear with their eyes exposed to avoid unclear vision, but I still prepared an eye mask.

After my wife and sisters put on the rubberized jumpsuits, the tight feeling they tried on made their sexy bodies begin to feel the pleasure and heat

Then my wife took out the chastity belt and put it on herself and each sister. Xiaoli seemed a little hesitant but finally put it on obediently.

I recalled Xiaoli's expression when her vagina was eager to be penetrated after she was in heat last time, and I could understand her hesitation better.

But after all, the key to a woman's chastity belt is attached to the bracelet ring on her wrist and she can open it anytime she wants.

For this and future SM stress relief sessions, I spent a lot of money to buy 4 sets of sex training chairs and placed them in the center of the room.

My wife led everyone to the center of the room and asked everyone to choose a seat and sit on 4 cross-shaped sex training chairs facing each other.

All I saw were four sexy bodies wearing black, red, purple and silver rubberized jumpsuits sitting on the training chairs.

Under the guidance of the soft lighting and sentimental music in the room, my wife and sisters have begun to show a crazy state like in heat.

The sex training chair is a bit like the octopus fun chair, but the structure is strengthened and the design is simple, mainly for the convenience of sexual intercourse and posture adjustment.

It is a bit like the old barber chair, which can be adjusted to allow the person sitting on it to sit or lie down. Of course, the result of its lightweight is that it is not bulky.

My wife and sisters followed my instructions before sitting down, unzipping their breasts and genitals, and then moved their buttocks to sit down.

Everyone except Xiaorong followed the instructions without hesitation, but Xiaorong hesitated for a moment and then did the same.

Almost every woman in the camera is charming and sexy. Xiaoli and Xiaoyu are even intoxicated and start to twist their bodies.

Knowing that they will be filmed throughout the process makes each woman more shy and excited, but wearing a hood also makes them more lustful and open

After my wife and her sisters exposed their breasts and genitals, they sat down and began to pull down the rape helmet hanging in the air and skillfully adjusted it and fixed it

I started to control each rape helmet to play the live video of everyone's sexy and lustful scenes captured by the camera in the SM training room.

At this time, the lust and memories of everyone present, including me, were awakened by the gradually sexy and lustful bodies and expressions of everyone present.

The rape helmet, which is also a head and eye massager, has begun to give women a warm and stress-relieving massage to help them relax.

After the massage, the women's bodies began to move, their breasts began to swell and the nipples on the areola began to stand up erotically.

Although the clitoris is restrained by the chastity belt and cannot be seen, but looking at their constantly twisting lower bodies, they must be in good condition and have been extremely lewd for a long time.

Through the earphones of the rape helmet, I can give instructions individually or in groups. At this time, I invite them to prepare to restrain their hands and feet.

The training chair is designed with buckles at the waist, wrists and ankles. Pressing the pressure switch will automatically lock the buckles to achieve the purpose of restraint.

When my wife sits down, her waist is pushed back to press the pressure switch behind the training chair, so that the circular restraint belt is automatically activated and locked.

At this time, my wife and sisters' anticipation for SM training made them obediently put their wrists and ankles in the fixed position of the lock.

And use your hands and feet to press the pressure switch to make yourself aroused and expectant of adultery. Your hands and feet are completely fixed by the locks.

I look forward to the night full of pleasure and joy that is coming. I think it will be an unforgettable experience and memory for me and my wife's sisters.
