When your orgasm was over you looked at the puddle of cum you created on your bedroom floor. "That was amazing. Good thing I was sent to this parallel world." You said and, remembering that, you looked around your room more carefully seeing what was different. You then realized that the furniture was not very different from what you had in your world, the biggest differences being the absence of the framed photos you had with your family and friends, and there was no wardrobe there.
In the midst of your thoughts and with your dicks now limp, you were curious about what else would be different, if you were some kind of freak or were you normal in this world, aside from all the differences in life from your alternative self to yourself.
Suddenly someone knocked on your bedroom door."[your name], are you awake yet? Head down to the dining room for your breakfast, don't be long as I have to leave for an appointment." your mom told you on the other side of the door, which was weird for you at first, since after confirming that you had the nimpho virus you were locked in your room and couldn't go out for anything. You then tried to open the door to your room, which was unlocked, and went downstairs in the nude, as you hadn't worn anything for months and didn't feel any need to do so.
You went downstairs and arriving in the dining room you noticed right away that although all the chairs were in their usual place, there wasn't a table there. You wanted to question, but realized that it must be normal in this world and decided to try to act like nothing was different.
"Mom, where's my breakfast? I thought it was ready." you said, calling your mother
"Everything is ready, just feel that I'm going there." your mother said and you obeyed her, sitting in one of the chairs and waiting a little until she arrived. When your mother arrived in the dining room you saw that she was also naked and, like you, she had huge breasts and some erect cocks between her legs, but unlike you who had four, she had three, and her balls were smaller than yours as well, having the size of soccer balls.
Admiring your mother you realized that she didn't bring you anything she ate, and feeling the hunger tighten in your stomach you rumbled. "Mom, where's my breakfast? Didn't you say it was ready?" you asked
"It's right here, silly, I'm prepared to fill you up." your mom said, walking up to you and putting the tip of her middle dick in front of your mouth.
You got turned on by the sight and your dicks grew hard again, you wanted your mom's dicks and you put her central dick into your mouth not caring if she would like it or not, but she just moaned and helped you like if that was exactly what you did. Your mother then asked you to hold your breasts firmly in place, you didn't know what she wanted with that but thought it would be interesting so you did as she asked.
Yourr mother positioned her left and right cocks against your nipples, then pushed.
To your surprise your nipples expanded allowing your breasts to be penetrated by your mother's members. Having your breasts penetrated proved to be a pleasurable sensation, similar to having your pussy penetrated.
With two of her cocks inside your breasts and one in your mouth your mom just fucked you, meanwhile you've pulled your ballsack closer to reach and shove an entire hand up your pussy. You enjoyed it until your mother came, each jet of her cum was filling your stomach and your breasts, which pushed you to the limit and made you come too.
Your mother's orgasm lasted 5 long minutes and when she stopped cumming your own orgasm it was still far from over. Your mom then took her dicks out of you and bent down sticking one of your dicks in her mouth while you came, swallowing all your cum that came out of that dick.
Just like she did with you, you ended up filling your mom's stomach with your cum while she was being bathed in the white seed coming out of your other 3 dicks.
When you stopped cumming your mother took your cock out of her mouth and said "Your cum is as good as ever."
"Yours too." You said, feeling sexually satisfied at the moment and having your hunger sated.
After that you went to your room, where you sat in front of your computer and went online and researched human physiology, because you thought it was weird that your mother had 3 dicks while you had four, since you didn't expect the people in this world could have as many genitals as different from each other. In your research you found that in this world there were only dickgirls and that they all had multiple dicks, with a minimum of two and a maximum of 5 dicks. The bigger the amount of dicks the girl had, the bigger would be the average size of her balls and consequently the duration of her orgasms. The average time of the one with two dicks being 2 minutes, one with three dicks cum for 5 min, one with four dicks cum for approximately 10 minutes, and those with 5 dicks came to cum uninterrupted for up to half an hour before having their balls, with a diameter almost equal to the length of their entire legs, were completely empty. They had their vaginas at the base of their ballsacks, with the exception of the ones that had two dicks, as these didn't have the female reproductive system.
You also learned that their cum were extremely nutritious and could replace any meal, allowing them to live a healthy life just by eating each other's cum, having any other food just as an option.
In this world everyone was a nudist, so no matter where they went people were always naked, with school and work uniforms reduced to a tie with the logo of the company or school. Clothes existed, but only those for some protection, such as radiation, bees, space suits, and the like. You also found it interesting to know that sex in this world was treated as something so casual that it could be done anywhere and with anyone you asked.
