*CUSTOM* My younger brother has approached me with an art project that he needs to complete, consisting of sketching the female form. And since he doesn't know any other girls he can ask, he is hoping I will help. I am always eager to help him out, so I agree...not knowing that his plan is more devious than it appears. I agree to pose for his drawing....but I tell him that I am not going to take off my clothes in front of my brother. He agrees, but I slowly learn what he has in mind as time progresses. He asks if I will let my hair down and take off my shorts so that the tone of my legs is visible...saying that I can use my shirt to cover up my panties. I give him a skeptical look, but agree and take off just my shorts and sit down on the couch. At first I sit modestly with my legs under me so that the shirt covers most of my lower body. My brother says he wants to feature my nice legs and asks me to open my legs and lie back...so that my pussy is thrust forward toward the camera, but leaving the shirt to cover between my legs. He starts to sketch, but after a few minutes he stops...seemingly not satisfied. I ask what's wrong, and he states that something is not quite right. He says it would be better if I could unbutton my shirt and drop it off one shoulder...to create more of an artistic look. I tell him that I'm not wearing a bra and wouldn't be comfortable with that....but after his obvious disappointment, I reluctantly comply. I completely unbutton my shirt and let it fall off one shoulder...accidentally revealing one boob. I begin to look uncomfortable and look around nervously, reluctant to make eye contact. After another minute passes, he again seems not satisfied. I ask him what is wrong now....and he says that he can still see a portion of my panties, and that it is kind of ruining the look. I say that I am NOT taking those off....but he begins to beg, wanting to get the drawing just right. I give him a skeptical look, but finally I let him make me feel guilty and want to make sure that he does well on the project, so I agree to take them off. I then get up and turn around...bending completely over as I SLOWLY slide off my panties. I am so flustered and trying to keep my shirt closed that I don't even realize that I am letting him see my pussy from behind as I bend over. I then give him another skeptical look, raising my eyebrows as I sit back down and continue the pose...with my shirt only covering between my legs. My shirt is now open to reveal my boobs, but I am too worried about showing my pussy to care. I tell him that I think he had this planned all along, but he swears that is only for the school project.... I roll my eyes at him. After a couple more minutes, he becomes completely irritated...saying that this is just not going to work. Concerned, I ask him what is wrong now. He says that his teacher is going to be looking for something more erotic...a sketch that really shows off the female body...and the shirt just isn't going to work. Starting to get frustrated, I ask him what I can do to help get this done. He tells me that he thinks I will need to be more exposed in order to get the look the teacher is going for. I act embarrassed...saying that I don't think it is a good idea for him to see his me that way because I'm his sister. Now I realize what he had in mind all along, but I am eager to get this over with...so I agree. I tell him that he will owe me a BIG favor after this. I then decide to make him uncomfortable too, so I open my legs wide and give him a sultry stare...attempting to fluster him. I say "is that what you were wanting to see"? I then pose with my legs open wide. I occasionally give him looks of disapproval and eye rolls...saying that I notice that he is enjoying it a little too much. I continue to look embarrassed as my brother gazes at my pussy. I question him about staring at my pussy so much, and he assures me that he is trying to get the sketch to be perfect.
