Update 05
We were eating Bhelpuri while talking about general thing. I was glancing at Didi occasionally since she was so close to me. She was wearing black crepe material skirt and grey loose top. As she took Bhel in Puri and about to put in mouth Suddenly due to wind force her skirt rod up exposing her thighs. She did not hurried to cover herself as in one hand she had Bhel and in other Puri. She eats Bhel, which was on Puri put the Puri in Bhel and then straighten her skirt tugged under the leg so it'll not rod again and she started to eat again.
Although it was dark there but moonlight was enough to gave me ample look of Didi's milky thighs. Seeing her thighs I got aroused. After when we finished Bhel I asked her,
"Let's go down behind the rock".
"Why?"
"It'll more comfortable down there", I said her.
"Why! Aren't you comfortable here? She asked me in teasing tone.
"I'm! But no privacy", I looked straight in her eyes.
"Why you want privacy Sonu?" she smiled mischievously.
"You know very well why!" I winked at her.
"Ok! But just for a while. We're already late", saying that she stood on rock just below us.
Hurriedly I jump up took our bags and headed down. There was one comfortable place between two big rocks. I realised we could have great privacy there. I sat there keeping our bags front of us and Didi sat near me keeping one feet distance between us. I asked her to come closer. She moved barely touching me.
I put my hand around Didi's shoulder and pull her more closer. I sat for a while like that then turned my face to her. I whispered in her ear,
"You're beautiful Didi!"
"Oh really Sonu?" she said teasingly.
"I'm not joking didi! I'm mad for you" I was brushing my lips against her ear lobe.
"Oh Sonu...! She just said that.
"Can I kiss you Didi?" I moved my mouth toward her cheeks.
Didi didn't say anything just leaned her head on my shoulder. I lift her face holding her chin. She looked in my eyes and closed her eyes. I was so hot holding my didi that I eagerly put my lips on her lips.
God! What a luscious her lips were. I felt her lips very hot. As I put my lips on her light moan came from her throat. I kept kissing her for a while. Although we didn't kiss like a hot lover or French kiss type but that was enough to arouse both of us. She was sitting my right side and I was embracing her in my hand.
I slide my hand down on Didi's breast and started to squeeze them. I was more comfortable fondling her breast there as there wasn't any fear about mother or anybody. I fondle her breast for a while from her top then slide my right hand, which was on her shoulder inside her top from neck. I squeezed her right breast through her bra. That was bit uncomfortable position for both of us. So I removed my both hands and placed them on her waist then slowly I raised her top and insert my hand inside cupping her both breasts in my hand.
Didi wasn't resisting. She was letting me do anything. I was kneading her breast now forcedly. All she was doing was moaning lightly.
I brought my both hands on her back and unhook her bra. As I unhooked bra straps fell under her armpit. She didn't resist. I again brought my both hand front and move bra cup up from her breast. I placed my both hands on her bare breast for the first time. As I cupped her breasts Didi stiffened and hold my wrist tightly. Not to stop me but her intense excitement cause her to shake her body. I was also horny then. My cock was hard like rock in my jeans. It was straining there. I felt to freed it and jerk off right there but I couldn't do that there.
I was now fondling Didi's breast violently. I was squeezing them, kneading them, cupping them. Her nipple was erected hard like rock. Frequently I was pinching them in my fingers. Her body would twitch when I pinch her nipple. I had fondled her breast quite enough and I was eager to suck them now. I lean down and placed my lips on her right nipple. All the time she was closing her eyes so she didn't know what I was doing.
When Didi felt something hot on her breast she opened her eyes and saw that I was sucking her nipple. That must have aroused her very high. Sight of her kid brother sucking her breast makes her violent. She started to breathe faster. Her body was shaking slightly. She holds my hand tightly, As I was sucking her both breasts alternatively. Her grip tightens on my hand. Tempo of her Shaken body was increased certain level. And husky moan came from her throat. Her body twitched for the last time and she calm down gradually.
Since my head was down near Didi's crotch sucking her breast. I sensed faint aroma of women's cum there.
Oh my god! Oh my god! I caused my sister to have orgasm by just sucking her breast. She came such a intensely that I could clearly smell her women aroma. I rose my head from her breast and kissed her on lips cupping her breast with my hand. Then I slide my hand down on her belly. Passing her navel as I reached elastic of her skirt,
"No!" she holds my hand there.
"Why!" I asked her.
"Don't go down there"
"But why Didi?"
"It's mess down there"
I kissed her on lips and said in erotic tone,
"Did you came Didi?"
"Yes..." she barely, said.
"Did I cause you to came?"
"Oh Sonu! Yes! You are so eager that I couldn't control".
"You like that Didi?"
"So much" saying that she pressed her lips against mine. First time my sister kissed me like that.
"Come on Sonu! Enough for today. We are too much late"
I kissed Didi passionately one more time and freed her. She hooked her bra and stood up straightening her skirt. Then we headed towards road. I was holding all shopping bags in my hand. While walking she said,
"Oh! I am feeling uncomfortable down there"
"Why? What's wrong?" I asked worriedly.
"I mean! It's mess down there. My panties wet and sticky", she said shyly.
"Sorry Didi! I cause you embarrass", I said feeling guilty.
"Never mind Sonu. Its not your fault", she comfort me saying that.
We walked silently for a while. I was thinking about her condition. She had to go all the way up to home with that wet and sticky feeling. Suddenly I had an idea.
"Hey Didi! May I suggest you something?"
"What Sonu?"
"There is one public toilet ahead. Just go to ladies toilet and changed your panties... you know what I mean? You have that newly purchased one".
"Better idea Sonu!" she said with smile.
As we approached to that public toilet Didi took her last purchased bag from me. She was about to turn to go inside I called her and said in low voice,
"Didi! Since you're changing your panties. Change your bra also. You could check that front hook bra whether its ok or not".
"youuuu..! Smart boy!" saying that she blushed and went to the toilet.
