Reverse World

She led him to the largest sofa in the room and asked him to lie down on his back. He recognized that she wanted to keep the initiative this time too by being the one on top instead of the other way around. Just as she said, she wanted to fuck him with her ass and not get fucked in the ass, a difference that Benjamin had gotten used to now in this world. Not that he had any sexual experience from the previous world, of course.

However, in this particular case, he was the one who had the most knowledge and experience between them. When he saw her nude self simply riding him and directly going for anal sex excitedly, he hastily stopped her before things took a turn for the worse. In this world, young women viewed anal sex as something both erotic and exotic and didn't have an ounce of apprehension toward the act itself. This was a big mistake, according to his experience. Dry backdoor sex was unappealing at best and painful at worse, and that applied to both partners.

"Wait a second, Nova. I think we should lubricate ourselves a little or it might hurt."

She reacted exactly as he expected, as if she suddenly realized she had almost hurt him. Even now, she typically didn't think for a second that it could hurt her too, which wasn't completely wrong either. Truthfully, even if it did, women would simply power through it with sheer willpower and ignore the pain.

"You're right, I was too inconsiderate. Just a second."

She switched her target and penetrated him with her pussy for a few seconds, contracting it a few times around him. She then raised her hips again, checked that his dick was full of her fluids, and aimed at her asshole again. It would have been even better had she been lubricated too but that would have to do for now. The two teenagers now excitedly watched her lower her ass on his cock. Soon, his glans touched her puckered hole and she pushed down harder until it forcefully entered her with a slight lewd noise. They both let out a moan of pleasure and she hastily continued her descent, much more fluidly now that the bottleneck was crossed. Her ass cheeks finally clapped against his thighs and she took him fully inside her, her entrance contracting against his dick's root.

"So this is anal sex. Darn, you're so large inside my ass. It feels weird, in a good way. I love it."

"You're as tight here as in your pussy. It feels incredible for me too."

Her insides twitched joyfully at his compliment, stimulating him even more. She began to move her waist up and down, without any hurry. As usual, anal sex gave quite interesting sensations to him. The strong contraction on her anus was great but it always felt quite weird to not hit anything at the end of the penetration. He was now used to poke women's cervixes when having vaginal sex and anal was greatly different from that point of view. On top of that, even though her insides were very hot, they were also much drier than her pussy, giving a different kind of sensation. Of course, he liked both vaginal and anal sex, especially the fact that going for one or the other could make for a good change after focusing on one of the two for a long time.

Nova seemed to be of the same opinion, moaning happily every time she moved his cock inside her. Still, it looked like she was much more calm now than at the start of their session and she took her time to feel him into her, just like when she first gave him a blowjob. He guessed that the few orgasms she managed to reach before helped a lot to keep her from being too frantic about it.

After a minute of slow anal sex, Benjamin thought to enhance their experience. He put his hands on her breasts and massaged them delicately for some time. She didn't react much at first but when he started to knead them rhythmically, she moaned a little louder and smiled at him.

"Do you like my breasts, Ben?"

"I do. See, they fit perfectly into my hands. They feel so soft, I love them."

"Yeah? That's good."

She had this indulgent grin that women had when he played with their chests. Most women didn't consider those as anything too special, some of them even finding them cumbersome. He knew, however, that some breasts were quite sensitive and wanted to test it with Nova. He continued to massage them while now putting a particular focus on her nipples. He used his palm at first but then switched to his fingers, making circles around them before flickering or lightly pinching them. It seemed Nova was in that category of women too because she reacted well to what he was doing, a little surprised herself that it felt that good.

Under that additional stimulation, she accelerated her movements. After a short time, she was going fast enough that he knew she was trying to climax. Accommodating, he also focused on his cock, aiming for a simultaneous orgasm.

"Mhmm! Mhmm! This is amazing! Anal sex is so good! Mhmm! I'm going to come soon!"

"I'm close too. Don't stop, Nova, just a little more. Let's come together."

"Yes. Mhmm! Aahh! N-no, I can't. I, I, I'm cummiingg!"

She dropped herself strongly on him one last time and climaxed, her whole body trembling and her pussy ejecting a few jets of fluids. Her anus contracted strongly around him but it didn't manage to finish him off, unfortunately. She breathed hard for a few moments, recuperating from her high, before looking at him, full of shame.

"I'm sorry, Ben. I came by myself."

"Don't worry. We can just go again, right?"

She nodded, red in the face, and resumed bouncing on top of him.
