I was in my sister's room borrowing (stealing's such an ugly word), some money. I had finally worked up the courage to ask Amy, this girl I liked, out and she said yes. Amy was really nice and very pretty, I'm not really sure why she agreed to go out with me. I'm pretty average looking and never really dated before, so I was shocked. The main reason I liked Amy were her two best qualities. And they were on her chest. (Okay, I'm a pig. Sue me.) They weren't huge or anything, but they were pretty nice and I was hoping to play, squeeze, touch, lick and suck on them. Maybe more if Amy was cool.
I just turned eighteen a few months ago and Kelly, my sister, was nineteen. Kelly was sort of plain-looking but guys seemed to like her. She had a nice body, I guess, I didn't really pay attention, I mean she was my sister after all.
So, I found her stash, it was in her pantie's drawer, and took $200. She must have had close to a thousand. Now I was curious as to where and how she got the money. As far as I knew she didn't have a job, but she always had money.
If I had left right then the following events would not have happened. I'll let you decide if this was good or bad.
I couldn't help myself and started sniffing her panties. I know, I know that's gross especially since she's my sister and all. I just figured if I was going to see some (hopefully) tonight, then I want to know how they felt and if they smelled like, I don't know, pussy or whatever.
Then I heard her talking to our mom and ducked in the walk-in closet just before she came into her room. She had a couple of bags with her. I was peeking through the door, hoping for a chance to escape when she started taking off her clothes. Good, she's going to take a shower. That'll be my chance to leave.
Did she leave to take a shower? No! My sister took off all her clothes and started trying on bikini's. She had several dumped out on her bed. Her room (as well as mine) had a desk and a chair. She put the clothes she had been wearing on the chair.
Holy shit! There was my sister. Standing totally naked before me. The she really freaked me out by rubbing her tits and pussy a couple of times. Her tits were bigger than I thought they were. They had a teardrop shape to them and sagged when she bent over. Her pussy was shaved. Her butt was big. I really had the urge to smack it. Yes, I know how it sounds to want to smack my naked sister on her ass, but that's what I was thinking. If I didn't think I'd get caught, I'd pull out my cock and jack off to my sister. It might fuck up my plans to get laid latter on, but there was no guarantee that was going to happen anyway. And now I understood why Kelly was so popular with the guys. Hell, I'm her brother and I was hard.
She put on the first one. It looked nice. It covered her up, but still showed enough to be sexy. If that's the look she was going for. She kept posing in the mirror and jumping making her tits bounce. Then, she bent over with her ass facing the closet and lifted her butt cheek and dropped it, making it bounce. Then she smacked it a few times. This caused her fat ass to jiggle. My cock was super hard. I pulled it out and started stroking, not caring if I got caught.
After she put on the third or fourth one, I sort of lost count, she shouted for my mother to come and give her opinion about the one she was wearing. Then I watched, amazed as my mother started feeling my sister up. Kelly's nipples got hard. Then, she made Kelly turn around and pulled the bottoms together like a thong, even though it was a regular bikini bottom.
"Even if it pulls together, nothing shows," Mom explained.
"Yeah, I think I like this one the best," Kelly said. Then turned and looked directly at the closet.
"What do you think, Brian?" Kelly asked, ripping open the closet door. I lost my balance, trying to both cover myself and grab for the door. I fell to the floor, on my back, my hard cock sticking straight up through my undone jeans.
"Oh my God!" Mom said. "Brian, what are you doing?"
"Apparently jerking off to his sister changing clothes," Kelly said, pointing to my hard cock.
"Obviously you're enjoying the show," Mom said, also looking at my hard cock.
"Look. I can explain," I offered.
"Were you stealing money again?" Kelly asked.
"What? No," I lied. Denying it.
"Brian?" Mom asked.
"Okay, yes. But only because I have a date and I needed money."
"Who with?" Kelly asked.
"What?" I asked confused.
"Who. Is. Your, Date. With." Kelly said instead of asked, each word a sentence.
"Amy Silver," I replied.
"That explains, this," Kelly said reaching down and stroking my cock.
"I don't understand," Mom said, looking back and forth between us.
"Amy has big tits. Doesn't she?" Kelly said.
"I guess. I don't really know," I mumbled.
