She has to think about this

What the hell? He would cum inside her? But what if she got pregnant? No, wait, that is why he was offering to kiss her ass. Wow. This just got a completely new meaning. Wait, back to topic. Today was not one of her dangerous days. So there was no reason to have him violate her butthole.

"Front." She whispered.

"Not like that! Say it proper. Beg me to **** your cunt and pray to get pregnant as you usually do." She did not remember ever doing this, but if he said so, she must have just forgotten. She really should go into a hospital soon, since her memories seemed to be wrong a lot lately.

"P-please **** my cunt. I hope we get a lot of babies. I wish I will be pregnant soon." He smiled and unzipped, already fully erect. She was surprised at this, as he had involuntarily cum in her mouth earlier today. It was not even half an hour ago, and then he came again in front of the... no wait, that was an illusion and not the real one. But still, he already had one orgasm this morning, so how was he hard again already?

"Gladly." He said and thrusted inside. She expected pain from being taken like this, but it felt almost good. Figures, after what her mother had just done to her, even the biggest cock would feel acceptable to her used hole.

However, Derek was not feeling this right now. He seemed to go wild at it. No holding back, no taking care, he just thrusted away as fast and hard as possible. It was bearable for the moment, but far from nice.

Her legs were **** into the air, or rather almost next to her body, as he layed on top of her. This position gave her mother the ability to do something Linda could not have seen, as she did it behind Dereks back. The moment Linda started to feel the chill, she knew what was gonna happen. And also that there was no way for her to prevent it.

Her mothers colder-than-ice-fingers touched her butthole and entered it. The shock of frost made her cramp almost instantly, and it was impossible to say for her which felt worse at this moment. The sudden pain in her pussy from her brother still mercilessly going at it, ignoring, or maybe even enjoying her closing vaginal canal.

Or did her ass hurt more. She could not say how many fingers her mother had pressed in, but they were enough to shock freeze her. Her whole body was so focussed on these few digits inside her, that it was impossible for her to react to it in any other way but just not moving and praying for it to be over soon.

"Derek, I believe your poor sister is having a fever. Her asshole feels so hot around my fingers. Maybe she should stay at home today." Emilia asked just loud enough for all of you to hear.

"No, she will go to school." Derek said... and then he said something else, but even though Linda clearly should have heard it, the only thing that remained in her mind were Dereks words to her 'you should forget what we just said, and you don't care for it either', and as a matter of fact, he was right. Given the situation she was in, his words were not that important.

"Well, if you insist," Emilia continued, "then maybe you should at least give her a shot of medicine." Linda saw Derek smile while increasing the speed at which he was thrusting inside her. Then at the same time as he answered, Emilia pulled out her fingers of Lindas by now also ice cold asshole.

"I... Am... Doing... That... Right... NOW!" And with that he came all the way inside her.

"Oh, but I thought you should apply it the way most medicine should be taken by her. In her ass." She spoke almost caring, which was so contradictory to what she had been doing before, it was giving Linda chills.

"Hmm, maybe you are right. I should have, but I am out of medicine for now. Linda, once you are back home today, I will give you your shot. But I want it to be special for you, so... You know that anal never makes fun. You know that anything entering your butt will feel ten times as painfull as it would usually. And you are sadly not able to relax your butt if something is touching it. Also you think anal is disgusting and would never want to try it, and that includes assplay or anything relating to your butt. But those things only are true for today until we are both home again." All of that was true. She was confused how those things were about to change this afternoon, but for now, all he said were facts. This time they even went along with her memories, mostly at least. She always had hated it. Not that she had any memory of it being 'ten times as painfull' but it never was nice.

"Happy now, mom? Now she will most certainly not try out any anal today and you can see us do it later today as you wished." Derek said to Emilia. Wait. Did he just say he would try anal with her? No, that was not gonna happen. Or would it? She was confused, since... or maybe not?

Before she could finish or even form a clear thought Derek spoke again. "Now both of us have to go. Come on, Linda. Your make up is ruined, but I have a feeling you have make up stuff in your bag anyway, so just fix it on the way.
