It was a Friday afternoon and I was in my room playing video games when my younger sister got home from school. I heard her bedroom door close and I waited the usual 5 minutes before it began just as expected; the muffled sounds of her sobbing. My sister, Gemma, had been crying alone in her room for two weeks straight, and I didn't really know why. I'd assumed it had to do with her recent breakup.
She'd had a boyfriend, Casey, that she'd been with for 3 years. One night not too long ago, Casey had come over to see her. A few hours later he'd run out of the house like his life depended on it, and he hadn't looked back. After that night he just disappeared, not responding to her phone calls or text messages. My sister had been a zombie since. She went to school and she did her chores and homework, but she said nothing to me or the rest of the family, and she never smiled anymore.
I knew that breakups were hard, and she and Casey had been together a long time, but this seemed really excessive. I'd been through some breakups and they were hard, but I mostly held things intact. Mom just told me that girls were different and to let Gemma have her time, she would snap out of it eventually. Well, I tried but that particular day I decided to go do what I felt was my duty as her older brother, and try to help her out of this massive funk she was in.
I tossed down my game controller and pulled on a t-shirt since I had only been wearing shorts. I went to her room and knocked on her door.
"Gemma?" I called quietly, hand on the knob. If she didn't let me in, I was going in anyway.
"Go away," she whimpered miserably.
"I can't do that. I'm worried about you. Tell me what's wrong?" I asked. "I just wanna help."
She mumbled something incoherent.
I tried the knob. It wasn't locked, so I entered.
Gemma was lying on her bed, face down. It hit me once again how beautiful my sister's body was. She had long very dark glossy hair, a tiny waist, gorgeous round D-cup breasts (which she was currently lying on top of), and the most amazing pert little ass I had ever seen. At the moment it was on perfect display to me, as her white pleated miniskirt had ridden up a bit, affording me a generous view of the seat of her black lace panties and the sweet soft globes that were exposed to either side of it. My ex-girlfriend calls panties like this "cheeky pants" because they let about half your butt cheeks hang out.
'It should be a crime for high school girls to wear panties like that,' I thought, as I felt my cock stir and my balls tingle. I felt wrong looking at her this way. Not only was she my sister, but she had just turned 18 and was barely legal for any other guy my age. I was a 21-year-old college Senior, about to graduate in a month with a Psychology degree. I just lived at home with my family to save money, so I could work and pay tuition with my own money, instead of taking out massive loans like a lot of my friends. But the fact was, I was an adult, she was still a child. And I felt incredibly guilty every time I got turned on by her. Which was often, let me tell you. I didn't let her know, because I didn't want her to get creeped out or shy away from me. Out of the 4 kids in our family, we were the closest.
Besides, I was supposed to protect her from horny guys like me, right?
I closed the door behind myself and walked into the room, then I sat down on her bed, and though it killed me, gently pulled her skirt down over her round and inviting ass, for propriety's sake.
"You've been pretty down for two weeks now. I know it can't be just the breakup with Casey. Why don't you tell me what's really wrong?" I asked the sniffling, shaking female form before me.
"Can't tell you...Too ashamed....Never understand," were the phrases I caught as she sobbed into her pillow.
"Of course you can tell me. There is nothing you could tell me that would make me think any less of you,"I assured her.
At that, she turned over. She looked like a vision, dark hair spread out on the pillow like shiny sable, ample tits heaving, barely contained in the tiny pink tank top she was wearing that showed just a hint of lace from her black bra right where her cleavage came together. Her big green eyes were full of tears but still glimmered alluringly when the light hit them. Her plump pink lips were parted, glistening, begging to be kissed. She was a walking wet dream.
What did she have to despair over? The world should be her oyster, right? The world itself turned for pretty girls like her, and she was not just pretty, she was bright, too. Hell, she could have anything she wanted! I was a guy, but I had a great life, too, since like my sister I was smart and considered to be very good looking. I'm 6'1 and I have light brown hair and blue-green eyes the ladies can't stop talking about. I'm not muscular but I am toned. I can get pretty much any girl I want, and I do. I'm definitely not sitting home on Friday nights crying like my sister. So what could be so wrong as to cause her to do this?
"Something....horrible...happened with Casey," she confessed, darkly.
"What do you mean?" I asked. Then I got a horrible idea -- did he do something to her? My fist began to clench on its own. "Did he do something to hurt you? Just say the word and I will curb stomp that little nerd! I can't believe this! He always did seem like a spineless little pussy -"
"No, it was me," she said, closing her eyes and sighing. "It was me."
"Well, what happened?" I asked, now totally stumped. My sister was very meek, always avoiding confrontation. She wouldn't hurt a fly, wouldn't cheat on anyone, and I doubt she would even start an argument with Casey. What could she possibly have done?
She took in a shaky breath and spoke. "Nick, have you ever felt that there were other sides to you?" she asked, eyes still closed. "Other parts of you buried down deep in your subconscious, just waiting to come out when the time is right?"
"Um....no," I said, lost and now starting to get even more concerned.
My sister sighed, and turned over facing away from me.
"I knew you wouldn't understand," she said in a small voice.
"No! No! I am trying to understand! Help me?!" I cried. "I need more information! What happened with Casey?!"
"I scared him away."
"Huh?"
"I scared him. He's literally afraid of me. When he sees me in the hall at school, he goes white as a sheet, and then he runs the other way. Literally runs."
I laughed. "What's so scary about you?" I asked.
"When I get...." she trailed off, shaking her head. "No, I can't, this is too embarrassing."
"No, keep going. When you get what?" I prompted. I just had to know what was going on now. It must be something really weird. Casey was a bit of a pussy, yes, but this reaction he was having was extreme.
"When I get...um...horny," she said, and sighed again from the embarrassment and her unwillingness to talk about this with me. "I change."
"Into a vampire, ah ah ah!" I teased.
"Get out!" she cried, sitting up, eyes blazing, pointing at the door. "I knew you wouldn't take this seriously!"
"I am, I am! I'm sorry!" I yelped, holding up my hands in apology and surrender. "I'm sorry! I was just trying to lighten the mood!"
"Well, you can't. This is serious, Nick. I'm a freak. No one's ever going to love me!" she wailed, as she put her hands to her face and started to boo hoo in earnest.
"Don't say that! Come here," I said, taking her in my arms and holding her. "Tell me what happens? What makes you think you're a freak? It can't be that bad."
"It's soooo bad," she said, woefully. But she pulled away from me, facing me on the bed as she began to tell me the story. "I never went very far with Casey until two weeks ago. I had let him touch my boobs a little before, and that felt good. But a couple weeks ago he touched me, you know, down there."
All I could think was that Casey was a stronger man than I. If he was really dating a girl as hot as Gemma and not ramming it into her cunt and ass on a daily basis, he should be elevated to sainthood. But I kept that thought in, for obvious reasons. It was obvious that unlike most girls who looked like her, my sister was actually very innocent. She seemed almost completely uninterested in sex. I'd always thought she just never allowed me to see that side of herself, but I now knew that side hadn't existed at all until recently. Strange...
