During the rest of the day, Tanya and David discussed more about the fact that she is from another world while creating their own theories about what could have caused this.
As they converged on Tanya, she learned that this world she came into was almost an exact copy of her original world, with the only difference being that there was not a single vagina in the world. In this world both men and women had a dick and balls, but the female dicks and balls were much larger than those of the men with the smallest known ones, at least twice the size of the dick of the man who had the largest.
Late at night, already lying in bed with her husband, Tanya couldn't sleep. Without knowing if she could reverse the exchange and return to her body in her own world, she decided to treat the body in which she found herself naturally. Soon after she started thinking about her cock, becoming more curious about its functioning, which ended up making her cock hard, reaching 16 or 17 inches for what she believed.
"Hey honey, are you awake?" Tanya asked
"Yes, I am. I wonder if sleeping with you, I'm not cheating on my Tanya. Would she be mad at me if she knew this?" David said
"Are you worried about that? You can rest easy, she won't be mad at you." Tanya said
"How can you be so sure?" David asked
"From what I saw, her personality must be the same as mine, not to mention that we changed bodies and she must be right in my world along with your version from there. I know it is strange to know that my husband is sleeping with another woman and that the other is me, so I don't get angry. I'm sure she knows that too and thinks the same as I do." Tanya said
"Yeah, you're right."David said, sat on the bed and looking at Tanya asked "And you wanted to tell me something when you asked if I was awake. What was it that you wanted to tell me?"
"Well, it's just that I've never had a dick before and I'm finding the experience interesting, and I wanted to know what sex is like in this world since there are no pussies in this world. With a dick this big it doesn't look like I can fuck anyone." Tanya said
"It's simple, women don't fuck anybody." David said
"So what's the use of having such a big dick if we can't fuck anyone? It is useless to have sex." Tanya said
"Do not be discouraged, I show you how it is done in this world." David said putting his hand on the tip of Tanya's cock. He then took the blanket off and started sucking on the end of her cock, continuing for a few minutes until, and when he stopped, he looked at her face with a line of precum connecting the tip of the cock with his mouth. "Now you're ready for the main course." he said and stood up, his dick hard, and asked Tanya to stand up too, which she did.
Tanya watched when her husband took her cock and put the tip of his own member against hers, mainly because his 8 inch cock looks tiny next to hers. She didn't know what to expect and was taken aback when he pushed and his cock entered her urethra. She didn't know what to think, especially after he started kissing her while he fucked her dick, all she knew was that it was better than she expected. She then began to caress her cock, being able to feel David's inside, but was a little frustrated when he came because she had not yet had her orgasm.
"That's it? But I haven't even come yet." Tanya said
"There is a biological block that prevents a woman from coming while her dick is being penetrated, so I must go to the next part." David said and went behind his wife, fucking her ass right afterwards
After that Tanya couldn't take much and finally had her own orgasm with her husband, who came again. Orgasm was unlike anything she expected, as well as much more intense and time consuming. When she finally finished she saw the dirt she had made on the floor and on the wall in front of her, but David told her not to worry because he would help her clean it up.
While they were cleaning, David said "Tanya, I'm curious about a subject. You say that in your world women do not have balls, so how do babies be born in your world?"
"Babies are formed and grow in a woman's womb for nine months and are born out of the vagina." Tanya said
"Babies form in the womb. And where is that?" David asked
"It's in our belly. From the question I can believe that the women of this world do not have a uterus, right?" Tanya said
"Exactly. The women's bladder are much larger than that of men, so they can spend more time without going to the bathroom. In our world babies are formed inside women's testicles, which increase their size during pregnancy. Delivery takes place with the baby coming out of their cock." David said
"A baby inside the testicles? For this I did not expect." Tania said
David looked for an image on the internet with his cell phone and handed it to Tanya saying "See, this is a pregnant woman close to giving birth."
Tanya saw the photo and saw a naked woman. She already thought that having balls the size of melons was overkill, but the testicles of the pregnant woman were the size of yoga balls, which she believed should be difficult to walk with. After that she returned her husband's cell phone and they went back to cleaning the room.
