"I know, right?"
Benjamin answered with a cheeky smile, making her laugh. They started to clean themselves up and put their clothes back on. Chloe made a regretful face when she was not able to see his nude body anymore, which he ignored. Once they were proper again, he asked her.
"So, did you learn a lot about men's bodies?"
"Yeah! It was nothing like porn! I was totally surprised!"
"That's great. Hopefully, now you will be readier for when you get yourself a boyfriend."
"Hm, yeah, but you know, Ben, the boys my age are nothing like you. They're so snob and avoid girls like the plague. I don't really want to have a boyfriend among them."
"I see. Perhaps when you are older, then."
"Yeah. But Ben, until then, c-can we do something like today again?"
"You little devil, I said it was only this one time right? And now you have seen everything already, haven't you?"
"Huh... please, Ben? I will get good grades at school, I promise!"
She made puppy eyes at him, making it harder for him to refuse.
"What does that have anything to do with this? Haa, fine. If you can get a perfect score on your next exam, we can do it again."
"What? A perfect score? That's way too hard!"
He knew her school results were not that great, hence choosing that condition.
"You can forget about it, then. Alright, time for me to start preparing dinner, see you later, baby sister."
"I will do it! You will see, I will do it! I can do it if I put my mind to it!"
"Sounds like the barking of a future defeated dog. Well, good luck anyway."
Benjamin left her room, to her still shouting that she would show him, and went down to prepare dinner.
The rest of the day went on as usual, except for the fact that Chloe was glaring at him with flames in her eyes. Well, if she could really achieve it, it wouldn't be such a bad thing in the end.
The following day, Benjamin started his morning routine and arrived at the school infirmary as usual. The second he knocked on the door, Sasha opened it and pulled him inside, before quickly closing and locking it again. She then hugged him without a word and kissed him, full of passion. They went on at it for a minute before she separated herself from him. Contrary to usual, she seemed to be hesitant about something when looking at him. Benjamin asked her.
"Is there something wrong, Sasha?"
"No, nothing wrong. But today, I have a suggestion. Will you listen to it?"
"Of course. What is it?"
"It's this. W-would you like to try anal sex today, Ben?"
That actually didn't surprise him too much. He had plenty of vaginal sex with her and, as a horny woman from this world with unlimited access to a sexual partner who was himself full of curiosity, wanting to try anal sex was pretty much a given next step for her. In this world, anal sex was considered something that women dreamed to have and men mostly didn't want to think about. As such, Benjamin was probably the perfect partner to try it with, in Sasha's mind. On the other hand, he had also been very interested in trying to fuck her ass, and the idea made him harder than usual. Of course, he didn't forget to act his innocent boy persona, since he had managed to keep being in character for so long.
"Anal sex?"
"Yes, women have three holes, their mouth, vagina, and their anus. Anal sex is the act of inserting the penis in the woman's anus instead of the vagina."
"I see. But, isn't it dirty?"
"Don't worry! I prepared myself properly and everything is perfectly clean, I swear!"
She seemed eager to convince him so he played along with her.
"You don't need to swear, Sasha. I trust you completely. If you want to have anal sex, that's fine with me."
"Oh, really? That's great! Let's take our clothes off and go to the bed now."
They removed their clothes and she made him lie on the bed, his cock already standing up, as usual. She took out a small bottle from next to the bed and made the liquid inside flow on her hand. She then put her hand around his dick and applied the liquid to it, explaining.
"Since the anus doesn't produce its own lubricant like the vagina, it is common to use a lotion like this one to avoid hurting the penis during anal sex. If there is none on hand, people would often use a substitute, like saliva or vaginal fluids."
"Vaginal fluids, meaning they would first have vaginal sex before switching to anal sex?"
Sasha blushed a little bit but nodded anyway.
"That's right. But, to tell you the truth, a lot of men don't really like anal sex. I haven't tried it before either. That's why I would understand if you found it dirty or repulsing."
This was one thing he liked about Sasha. Even though she sometimes tried to "trick" him, she mostly ended up spilling the truth in the end, as if she found it unbearable to lie to him for too long. That was also probably proof of her kind heart, where even her incredible libido and desires could not completely make her do too many wrongs to others.
"Not at all. We have done a lot of things together and never once did I think like that. There is nothing dirty about you, Sasha."
It was a bit of a cheesy line but it had the expected effect. Sasha took his head into her hands and went for another passionate kiss with him. This one lasted longer and when she finally moved apart from him, she panted, saying.
"My angel. I don't deserve you."
"That's not true. I always said it, right? You are an amazing person."
She smiled at him, happy from the praise. However, time was ticking and they couldn't continue chatting if they wanted to achieve their goal before school started. She climbed on top of him, facing him while aligning his penis head with her butthole. She queried him one last time, full of expectation.
"Are you ready, dear?"
Benjamin nodded.
