Not what she wants to

She was about to open her mouth as her brother spoke first.

"Don't let it come out of your mouth!" He told her. Of course not, what was she thinking. She never even planned to let his sperm leave her mouth. Instead, she put her head in the back and spoke, or rather gurgled some words.

"u ast at ar arasm. U erert!" She was visibly mad at him... but he just laughed at the scene.

"I couldn't understand a word of that, but a fact is, you did touch me with your teeth in the end, so you go to school commando and in a miniskirt today." Fuck. She did not have the feeling that she did, but if he said so, she probably did. Most likely when he was cumming. Damn. Still this did not change the fact that she was angry at him. She wanted to yell at him more, but if he really couldn't understand her... no, she could not spit it out, that would just be wrong.

"an u heez..." She started but he laughed again.

"Talk to me properly if you want." She closed her eyes, and mouth for that matter, and silently prepared herself for what she was about to do. With a lot of self-convincing she swallowed it all. The taste kept stuck in her mouth and she felt gross. But now she could talk.

"You just had an orgasm, you pervert! This had nothing to do with cleaning. You **** me into giving you a blowjob!" She raised her fist at him but thankfully, he explained to her how the situation really was.

"No, sweetheart, YOU were so sensual with your cleaning that you must have forgotten who I was and gave me a blowjob. I couldn't do anything but you **** me to let you suck me off. But I am not your father so it is not my job to punish you for that VERY indecent behaviour. However, you owe me for not telling mom." Oh to hell with herself, what had she done? She sucked off her brother against his will. That is almost ****. She owed him big time. Even more, he was so chill with it. "Now redo your makeup, it has become worse!" As she expected before he said it, he was right.

A look in the mirror proofed that. However, the second she tried fixing it with more make up, which was hard, she saw him stepping behind her. The next thing she felt was his hand on her butt, squeezing both her cheeks at the same time.

"Ehm, Derek?" She asked, unsure, with all the things that happened just now, how to react. "I might have invited or **** myself onto you, but... please don't do anything to me. I know I gave the signs you could but I don't want this to happen, you are my brother, you get me?" He laughed.

"Linda, I am not doing anything. Everything you feel is purely your imagination. If something indecent is happening you are the only one to blame, because it is only in your head." Oh, god, did she just admit AGAIN to thinking about doing indecent things with her brother? She wanted to fall down and be swallowed by mother earth whole.

"I... I know you didn't do anything. I was just stating that in advance. So that you don't start doing things you get me? haha, what do you think I am, a crazy person who is seeing thinggggggs" she shut up as the fake-Derek behind her had started to rub her clit from behind. He then forcefully spread her legs wide and bend her forward. This was probably still okay. Since he was fake, there was no way something could happen right? Also to the real Derek she would just look like she wanted a closer look to the mirror. Nothing lewd here.

"oh fuck!" she moaned silently as the illusion went further, way further, than she ever went, or wanted anyone to go. At the same time he had entered her pussy with his index and middle finger... just to push his thumb into her butthole, gripping her like this. His second arm was hugging her around, grabbing her breast and squeezing it. It started whispering in her ear too.

"You will ask the real Derek now, if he would mind if you slept in his bed naked for the rest of your life. Or else I will put something way thicker than my thumb in your ass." The idea alone of that scared her to hell. She never wanted even that thumb in there. Not anything. That was a dirty place, not made for things to be put in. But even if it were, it hurts, is uncomfortable and was just something gay guys should do, and noone else.

"D-Derek. Would you mind if I sleep in your bed from now on. I would sleep in the nude... so you could check if I am naughty in the night. I mean with how I am acting I might need someone to check on me, okay? Please?" She begged him and he just laughed and said yes. She could not see where the real Derek were, but if he replied to her really spoken question, it must be the real one, even if it seemed to come out of the fake-Dereks mouth.

Said fake-Derek now smiled and spoke once more. "Now spread your legs and cheeks, sweetheart!" She was in shock but did as he told her.

"W-Why? I did as you wanted. Please, dont take my butt. Please don..." she begged whispering, hoping the real Derek wouldn't hear her.

"Advertise your asshole as good as you can for me." He whispered in her ears.

"Please don't thrust your cock into this tight and very fuckable hole. I don't want you to thrust your dick into this warm and wet opening, that is just waiting to milk you for your cum. Don't even think about how taking me up the ass would be the best fuck you could ever have with any girl in the world. I would hate you for ahhhhhh" And with that he did thrust into her. But not the advertised ass, but her pussy instead.

"I told you I would not fuck your ass if you did it and I keep my word. Now put your legs back together and touch your toes. Come on" He slapped her butt. She knew it was just an illusion but it felt so real. Of course, she only obeyed him because she wanted the illusion to go away, so as she closed her legs and bend over as far as she humanly possible could, pushing herself more against his dick and opening up to him at the entrance, but tightening up deeper in, she was close to crying. Again.
