I was going 18 at the time and my sister was almost 20. We are 18 months apart. She was the kind of sister that no brother would have dream of before all our relation changed. I was on a fitness training to take entrance examination into a military academy that involved physical test like fitness, swimming and interview. So I was on almost top physical condition besides I was the school's soccer team. She was always picking up on my study. Something like peeking into my room to check whether I am studying or else. But that result at my good grade and it's what I considered some years later. Well, talk about my sister, she was slim and about 5 cm. shorter with her hair hanging to her round shoulders. Her breast was about c-cup and poking out clearly that it always draws the boy's attention everywhere she goes. Our dad were in some managing position in his career so he was often went out for a party, receptions or dinner of the sort and that meant our mom would have accompanied him, leaving us all alone in the house until late at night. Besides studying, we enjoy scrabbles too even if I have less chance to win over my sister.
The night that the whole world changed for us was in start of summer. I passed the educational entrance examination and waited for the PE test in the next 10 days. I'd just returned from jogging and swimming from a clubhouse nearby and found that the garage was empty.
"Hey, I'm home." I yell.
"Yes, everybody in the neighbor knew that when you slammed the door." She yelled back from the kitchen. She was wearing a bodysuit short and a tight T-shirt, cooking the dinner. The hot summer air and the work out made her sweat beading all over her and the sweat soaking T-shirt showed me she didn't have a bra on.
"What's for dinner?" I look over her shoulder. Her smell struck my nose. She smells like musk and so arousing my penis starts to tickle.
"Something sure you can eat."
"Mom and Dad out, right?"
"As you can see. Don't you know that his car are not in the garage?"
"Woah! Give me a break. What's going on with you, sis" I tried to calm her down a bit.
"That rascals" She murmured. I suddenly knew she meant the boys from a family 2 blocks away that always whistling and yelling about her round breast.
"Oh! I see."
"What did you see?" She bellowed. "You didn't"
"I really seeing things that made those rascals go mad." I answered with a smile. She turned to face me and eyeing like she was going to burn me to ash.
"Youβ¦β¦" She flushed with anger. "Wait till Mom and Dad are back." She said when she noticed what I was looking at.
"I give up, sis, sorry. I'm going to take a shower. See ya." I said and run out from any trouble I might catch with her.
She didn't say anything during dinner even I tried to talk about my coming PE test. She began talking at last, it was about I'd better get myself ready for the interview. I told her that there is not a thing to worry about the interview and ask her to play Scrabbles. So we went to her room after finished with the dishes and have her bed for the game. As the air was warm I just wore loose shorts and a round neck T-shirt with no underwear and my sister wore a white short nightgown that hung just a little above her knees. Her gown was thin and wide necked so every time she bend over to place the scrabbles tiles I can peek inside her gown. I was so amuse peeking for her full-grown breast and that caused my penis to come alive. She didn't know her move made a live peep show to me. All she knew was I was playing below my standard and she started nagging on how was I pass the entrance exam with out noticing my tented shorts.
I enjoyed her breast so much I can't catch up with the game. Every tiles I put on board was the first decision and the shortest word I could think off so I can come back and admire her nice breast swaying in her night gown. Her skin was in cremated color and smooth. Her nipples were partly hidden under the fabric but sometimes clearly visible as I tried to extend the word line toward my seat so she must lean further to me. As the game went on most words form on my side of the board and she must lean more that she almost topple on the board. I don't have to tell that every time she lean to take her turn I could see most of her breast didn't I. She murmured something about the way I play my turn and, suddenly, noticed my tented shorts.
"What's in your pants?" Her burst alerts me from peeping into her gown.
"Er!.. nothing." I replied and trying to turn my lap to hide the tented shorts.
"Don't you try to make a fool out of me. What is that?" She put her rack down and look right into my eyes.
"I said nothing, can't you understand?" I raised my voice.
"Stop that bellowing!" She yelled. "Are you trying to cheat me, aren't you?"
"No, nonsense. I going to bed now." I put my rack down and stand up and face the door away from my sister.
