I was 18 at that time and attended the final year of high school.
The last two lessons of the day were deleted, so I came home from school earlier that day. As soon as I made the first step into the house, I heard strange muffled sounds...following them to the living room, I was gratified by a view I won't ever forget: lying on the floor, tied up like a sausage, there was my mother!
She was completely naked, her arms were tied behind her back at the wrists and above the elbows, then tied to her upper body by ropes positioned above and below the elbows, her legs were tied at the ankles and above the knees, and finally there was a rope connecting her ankles to her wrists.
Several overlying pieces of tape covered her face from cheek to cheek and from nose to chin; I could see that beneath the tape her mouth was open as if something had been introduced within, in order to prevent mom from closing her lips.
Her body was completely covered in sweat that made her skin shiny.
She was struggling furiously and obviously trying to say something, though from her mouth it came out nothing but unintelligible moans. Her eyes were wide open and staring at me.
I just stood there, frozen and speechless, mesmerized by that vision.
I was recalled to reality by my dad calling my name...he came out from nowhere, ordering me to go to my room. He had to repeat is command twice before I was able to understand what he was saying. Moving like a robot, I walked to my room, closed the door behind me, and began to reflect on what had happened...
I was confused and anxious. I had just found my mother bound and gagged in our own house: had she been the victim of a burglary? Besides, I found her completely naked: had she been hurt?
She was covered in sweat as if she had struggled against her bindings for a long time: perhaps were they hidden close to our house, waiting for me and daddy to come out, living mom alone?
To stay there, without knowing what was going on in the next room, was a real torture...
However, I was beginning to calm down and to notice the many inconsistencies of my assumptions.
First of all, the house was in perfect order and nothing seemed to be missing; secondly it was such an incredible coincidence my father coming home at that very moment: no, he must have been at home since the beginning!
And, finally, mom's desperate mmmmmmpphhing: she was trying to recall his attention, to warn him that I was there!
So, what was going on?
I was beginning to consider other aspects of that event.
I had seen my mother naked. Of course I couldn't see much as she was lying face down, but what I had seen was giving me strange feelings. I was regretting not having had the opportunity to observe her longer.
Dad' s voice calling my name cut off my daydreaming. Mom and dad were waiting for me in the kitchen; mom was sitting on a chair, now wearing a bathrobe. Again I felt the regret!
With a calm voice dad asked me why I wasn't at school. I told him of the assembly. Mom hadn't said a word yet. She was sitting with her legs crossed and was obviously still naked under that robe. I was trying not to look at her directly. Trying to keep my eyes down, I found myself looking at her feet: her left leg was crossed over the right, her left foot dangling in the air. I noticed the arched sole, the slightly arched toes and the toenails: protruding, oval-shaped and lacquered red.
I began to feel again that strange sensations.
All of a sudden mom spoke, telling me that I needed to understand what I had seen.
So mom and dad explained to me how sometimes even the adults they want to play; nobody seemed to notice the fact that I was old enough to know of the existence of sexual games between consenting adults, but I didn't say anything. Dad told me that he liked to see mom tied and gagged; mom that she liked not being able to move or speak: she loved the feeling of helplessness. Neither of them had mentioned the fact that mom was naked, so I did it. There was a moment of awkward silence. Then mom took courage and explained that she liked the feeling of shame; I imagined how ashamed she must have been when I found her and felt a strange excitement. Dad ended the conversation saying that I was certainly old enough to understand that I should not talk about that "incident" to anyone.
I confirmed and told mom if I could ask her a question: I was curious to know what she had been gagged with. She answered that dad had stuffed her mouth with a pair of her pantyhose.
"Were they clean?", I asked. Strangely, at that point there was the longest pause of embarrassment until then, interrupted only when my mother said: "Ehm, no... I wore them for several days... purposely...".
I kept silent, so she went on: "I wanted my gag to have a disgusting smell and taste... it makes me feel even more humiliated". I don't even know why, but as I heard my mother talking about the smell and taste of her feet, I had an immediate erection!
A crazy idea crossed my mind: what would have happened if I had asked mom and dad to let me play with them?Making to my parents an indecent proposal...
I was sitting in the kitchen with mom and dad, talking about "the incident" (as my father used to call it). I was at a point where I wanted at all costs to take part in their game, but I couldn't find a way to broach the subject...So I kept asking questions, waiting to find the right words... and the courage to utter them!
I asked my parents why they weren't at work that morning; the answer was that both of them had taken a day off on purpose: "Since you were at school, we thought we had the house to ourselves until the afternoon... looks like we were wrong...", said mom with a smile somewhere between embarrassed and mischievous, that made me more excited than ever.
Going on with the conversation, I discovered that they had started to play immediately when I left home; This means that mom had been bound and gagged for several hours before I found her, and that If I had not come early, she would have been bound and gagged for at least another two hours!
My parents confirmed that they didn't use to put a time limit to their games; mom always had only two choices: to succeed in freeing herself or remain bound indefinitely.
"Well, son, what do you think of this?", my father asked.
I saw the opportunity to make my request, but I only managed to say "Ummmm, I found it....interesting".
"I see", mom said, once more with that killing smile.
It was then that I realized that I had passed from a relaxed posture to a more rigid one, making my erection visible. Mom clearly had noticed it...
"Did you see anything you like?", she said, looking at me with piercing eyes...
So, the fact that I had seen my mother naked, it was mentioned for the first time: I was dying to say "YES", but I was terrified. My father came to my rescue, asking again (and explicitly) what I thought of their game: I took the opportunity and answered quickly "well, it looks pretty funny...I'd like to try once..."
I held my breath, amazed by my courage... My parents looked at each other, then mom stood up saying "We'll see... Now I'm going to dress..."
I couldn't do anything but watch her with desire, while she was carrying away my dreams... maybe. Or maybe not... indeed she hadn't said neither yes nor no.
I spent all day in a trance. I couldn't believe it had really happened.
I didn't see my parents again until dinnertime; everything seemed normal, we talked about this and that, as if nothing had happened. All of a sudden mom said: "Your father and I thought that next Sunday you could play with us, provided that you are still interested..."
I had to restrain myself from screaming. I succeeded in answering "yes" in an almost plain voice.
Dad asked me if I had any objection to their rules. "Absolutely not!", it was my answer, "Indeed, in this regard ..."
"Go on!" my mother said decidedly. I did it, looking at my father instead of her: "I'd like to be gagged like mom." Nobody answered me. After dinner, mom got up, saying "I'm going to search for a pair of pantyhose to put on tomorrow. I'd better take a new one, since I'm going to keep it until Sunday". I wanted to have a mirror to see my face.
Now all I had to do was to wait until Sunday...
... and finally came Sunday. When I walked into the kitchen for breakfast, I found my parents waiting for me. Dad was dressed informally, like every Sunday morning. Instead mom was a surprise: she was wearing a white shirt, a black skirt, black high-heeled shoes and flesh-colored pantyhose. "Hurry up to breakfast. We have much to do.", said my father.
Obviously I didn't need any prod.
After breakfast we met in the living room. We all stood in the center of the room. Mom told me to undress. I did so, as fast as I could. I felt strange to stand naked in front of my parents at my age, but I had no time to think of it: dad told me to turn and cross my wrists behind my back, then he tied them very tightly. The next move was unexpected. Dad took a piece of rope and doubled it, then tied it around my waist, leaving the spare part dangling from the front side; he passed each half of the double spare rope to one side of my scrotum, brought them together and passed them between my legs. Finally he wrapped it around my already bound wrists and connected it with the part encircling my waist. Then he fastened my arms to my torso, enveloping both in several rounds of rope. Following dad's instructions, I sat on the floor and let him to tie my legs above and below the knees and at the ankles. Final touch: a rope connecting my neck to my knees.
Once I was properly tied up, mom stood in front of me and started to undress. She removed in order: shoes, skirt, shirt, pantyhose, bra and panties, remaining completely naked.
Oh, did I mention I had a hard on between the skirt and the shirt?
Unlike the morning of the "incident" I could watch my mother's naked body at will.
She was in her mid-forties and of course rather overweight (but I wouldn't describe her as "fat"). Even when she was dressed , anyone could see that she had huge breasts. Now I had the opportunity to see them bare. Obviously, they were considerably saggy (time and gravity: they cannot be beaten!), but I found them wonderful! Free from the bra they seemed more enormous than ever! The areolas were the size of coffee saucers!
She knelt in front of me, holding the pantyhose she had just taken off. She wadded them up and pressed them onto my face. The smell was intoxicating. "I have worn them day and night and I have never washed my feet!" she whispered to me. Then she forced the ball into my mouth. Soon dad started to wrap packing tape around my head and didn't stop until it was clear that I would never be able to spit out the pantyhose.
Mom stood up in front of me again while dad was tying her hands. He applied to her the same technique already used on me. I saw the rope connecting her wrists to her waist, vanishing between her labia. Soon she was sitting besides me, tied up exactly as I was. Dad took her panties, wadded them up and forced them into her mouth. Though a skimpy thong, due to the size of my mother's ass, it seemed to be an effective gag, but dad wasn't satisfied. He warned mom not to spit out the panties, and then disappeared; he came back a few seconds later with another pair of my mother's panties and I could see that neither these ones seemed to be clean. Dad make them follow the previous pair, then wrapped almost the whole roll of packing tape around mom's head. Under the tape her mouth was wide open. Her cheeks looked like they were about to explode!
Since my father was determined to keep us bound and gagged all day, unless we could free ourselves, I thought it was time to test our ties..Finally we started to play...
Summarizing: my mother and me, we were sitting on the floor, in the center of our living room; we were fully naked and tightly tied up and gagged. My mouth was filled with a pair of my mother's filthy pantyhose, mom's mouth with two pairs of her dirty panties. Our mouths were completely useless: I could hardly swallow and I guess that mom's situation was even worse. The tons of packing tape wrapped around our mouths excluded that we could spit our gags.
Our wrists were crossed, bound behind our backs and connected to ropes passing through our crotches. Our legs were tied together at the ankles and above and below the knees. Our arms were firmly secured to the top of our bodies. It could be sufficient, but my father was a man full of (evil) imagination. Each of us had a rope passing behind the neck and fastened to the knees; it wasn't too short: I could still sit with my back almost straight and stretch my legs, though not completely.
I looked at my mom: bound and gagged that way she was as beautiful as I had never seen her.
The ropes sank in her abundant meat as if they would crush her, making her body seem even more luscious! I felt like I was hypnotized by her...
Suddenly I noticed that she was trying to get my attention. She was mmmmmmpphing furiously through her gag, though emitting only extremely muffled sounds. Wow, I had never thought that a gag could be so effective!
Anyway I mmmmmppphhed back, in order to let her know I was paying attention. I discovered that I could barely hear the sounds coming out from my own mouth!
Mom was trying to tell me that it was time for us to try to untie ourselves. She started to give me instructions, mmmmmmpphing through her gag and nodding her head. It was extremely frustrating: it took me a long time to understand what she wanted me to do, but we hadn't any other way to communicate. Guiding each other through our moans, we positioned us back to back and started to work on the ropes tying our wrists. The operation proved extremely difficult. Our wrists were tied to our waists, making each movement more complicated. Dad had placed all knots in the inner part of the ligature, so my hands would have had to turn around mom's wrists in order to reach the knots.
The same went for mom. Easier said than done!
We alternated ourselves: first my mother worked on my knots, then I did the same on hers.
Our efforts were accompanied by a soundtrack of moans and grunts!
Every time my mom tried to reach my knots, she pulled the rope positioned through my crotch, increasing the pressure against my scrotum. I guess that every time I did the same to her, I made her rope penetrate deep into her cunt.
We tried a long time, but without success. The next move was to try to loosen the knots that kept our legs tied. Needless to say, all the knots were positioned between our legs, so we weren't able to reach them.
I had more freedom of movement than my mother. Her gigantic boobs completely filled the gap between her legs and torso, restricting her movements!
In order to reach our goals we had to press our bodies against each other: whenever I felt mom's meat against mine, my penis winced!
After this sequence of failures, we had to stop for breath.
After a while mom recovered herself and began to crawl towards the couch. Arrived at her destination, she began using the couch as a support in an attempt to stand up. I imitated her.
After long efforts, we both managed to stand on our feet; it was then that I understood the purpose of the rope that connected our necks at the knees: we were able to stand up, but we were forced to stay bent at 90 degrees! Keeping the balance was extremely difficult!
Mom was a show in that position! Her huge tits were completely hung and it seemed they were about to touch the floor! Whenever she made a small movement for balance, her tits swung like pendulums!
She started to hop towards the door. At each hop, she was able to advance only a few centimeters and her tits swung and bounced, making more difficult to maintain balance.
I hadn't any enormous tits slowing me down, but following mom proved equally difficult.
Our destination was the kitchen, the right place to find a knife! We reached it after an eternity. Everything was in perfect order, there wasn't any knife around. Dad had thought about everything!
With great effort, mom reached the sideboard, but opening the drawer proved impossible for her: her ass was so big that her hands could not reach the handle! I exchanged places with her and tried: it took me at least half an hour to open the drawer only a little, but as long as we tried, we were unable to grab a knife.
Mom mmmmmmpphhed to instruct me to follow her: she reached the wall and slowly began to slide towards the floor. I immediately understood what she wanted to do: to take a knife, we absolutely had to get rid of the ropes that forced us to stay bent!
So we found ourselves sitting on the kitchen floor as we were in the living room, renewing once again all the attempts that had already failed!
Watching my mother, I noticed only two differences: first, she was completely sweaty (like I was, anyway); secondly, she had the soles of the feet dusty, due to the time spent hopping. I don't know why, but I found that detail very exciting!
In the kitchen we had a wall clock, so every time we made a break, Mom and I could realize the passage of time. Six hours later we were still sitting on the floor, naked, covered in dust and sweat, panting and above all still bound and gagged!
We hadn't made any progress: dad knew what he was doing when he tied us up!
He came to ask if we wanted to be untied. Mom and I both nodded our heads: neither of us could resist any longer!
First of all, dad carefully unwrapped the tape from our mouths, allowing us to spit our gags: for the first time after six hours, we were able to breathe deeply!
Then he took his time to untie us. When he finished, mom and I both lay on the floor, exhausted.
I crawled towards mom, lay down besides her, hugged her and sank my face between her boobs.
She began gently caressing my head, saying "Be careful not to remain without air!"
Her tits were so gigantic that the recommendation was not so ironic!
Dad spoke: "Judging by what I see, we would do better sleep all together, tonight!"
