With three women in my list so far, I felt like Casanova. Well not quite, as Casanova had many more women. I felt tired after so much activity and dreaded meeting sis at the breakfast table. She was there before me gloating over her new found information. I tried not to blush. Mom was around but if she had noticed anything different, she kept silent about it. The only thing she asked was that whether I was up all night looking at my puffy eyes. I did my best not to blush and mentioned something vague about working on an assignment. My sister cleared her throat and I gave her a murderous look.
I then remembered her comment about mom and couldn't help but check her out. She looked quite cute early in the morning with her ever present shapeless robe draped over her night clothes. Her breasts moved under her dress and I couldn't help thinking about sucking on them. My cock rose up to the challenge but I willed it down. I felt a leg on my thigh and it was sis. I blushed deep red as she pecked at my hardening cock under the jeans. She wore a skirt so I did the same making her squeal and stand up. Mom looked at the two of us and asked us to keep quiet.
I tried to avoid having to walk to school with sis but she wasn't going to let me off that easy. I sighed as she dragged me out of the house.
"Oh my god, Jake, did you fuck Aunt Em too?"
"Shhh sis, you are going to let the whole neighborhood know!"
"Tell me Jake, when did you first do it?"
She kept asking me and then I told her all about the washing machine episode and then about Wendy at the mall.
"Oh wow! You are one hell of a stud!"
I shrugged.
"You know what Jake?"
"What?"
"My panties are soaking wet!"
"Oh fuck, really?"
"Yeah."
We were walking down our neighborhood and there were a few people on the road. We usually go to school early to catch up on school work at the library.
"Tell me if how much you liked me sucking your cock, Jake."
"Oh gosh sis! Not now! I am getting a hard on."
She reached across and felt it. I almost jumped.
"What are you doing sis? What if someone sees us?"
"I don't care! I am so horny!"
Luckily we reached school before she could do anything more and I was able to calm her down. We are at the ground floor of the building that housed the science labs.
"Jake, meet me behind the science lab," she said.
"What?"
"Yeah!, Meet me there," she said and disappeared up the stairs.
My heart started beating hard. She wore a pink skirt which was upto her knees and a checkered shirt with a t-shirt under it. I stared at her disappearing up the stairs and with her skirt lifting suggestively according to her hip movements. The school was still not crowded. The science lab was at the corner of the second floor of the building we walked into and was the quietest part of the school at that time in the morning. My hands were shaking and my heart was hammering in my chest as I climbed up the stairs after looking around. There weren't many people about. I was kicking myself for following her but my legs had an agenda of their own. I was secretly happy that they decided to climb up the stairs. I reached the second floor and walked towards the end of the corridor and my sis was near a door that led to the emergency exit. She beckoned me towards her and she opened the exit. It was slightly dim inside and I could see the staircase winding down.
She pushed me against the wall and started kissing me hard. She pushed my hands to her breasts and I started to knead her over the t-shirt. Her shirt was unbuttoned and the t-shirt covered her torso tightly but it was made of a thin material. I could feel the outline of her bra. I pushed my hand under her t-shirt and her bra and started squeezing her breasts directly.
Her hand went to my pants urgently and unzipped it, taking my cock out. It was hard and pulsating and growing by the second. She moaned into my mouth while we kissed. Her hand was hot on my cock while she rubbed its length squeezing it lightly in her fist. The tip kept rubbing against her tummy. Then she parted her legs and lifted her skirt and I pushed my cock between her thighs and she tightened them around my cock. I dry fucked her thighs kissing her deeply. My cock got slightly soaked when it made contact with the crotch of her panties and it was drenched. With the help of her wetness, my cock slid easily, back and forth between her thighs. I crushed her against the wall as I moved faster and faster. I stopped as I was getting closer.
Then she knelt and started sucking my cock hard. I leaned against the wall and let her suck me off. I pulled her to me with my fingers gripping her head, forcing my cock into her mouth as I had seen in some of the movies. Her slurping sounds echoed on the stairway and I hoped no one could hear us. I felt my climax building up and I moved faster and faster. I had no choice but to empty my cum into her mouth. She swallowed all of it. Then I pulled her up and kissed her again tasting a bit of my own cum in her mouth. She had swallowed most of it.
"God sis, you are wild!"
"Mmm yes dear brother. I was going crazy this morning thinking about you and Aunt Emma," she said breathlessly.
"Well, I get excited when I think about that too."
"Quick! Finger my pussy and make me cum, Jake! I am so wet!"
Her whispers were urgent and full of passion. I was half scared about being found out but the atmosphere on the staircase was electric. I wasn't thinking straight at all. I guess a woman can do that to a man.
She leaned against the wall and I knelt before her, running my hands under her skirt. She was drenched and there was a minute stream of wetness dribbling down her thighs as well. I pulled her panties down and stuck my head inside her skirt.
I was getting better at finding my way around a woman. I held her legs apart and found her clit and started to lick it. I also found her ass hole and rubbed it lightly making my way inside its pulsating orifice. She gasped as she let herself be licked and conquered by my tongue. I pushed my tongue further down to lick the whole slit and pushed my tongue as far as I could in my kneeling position which didn't allow for much maneuvering. I loved the taste of her pussy and did my best to lick her.
However, she didn't last long. Her hands were around the outline of my head under her skirt and she shuddered a few times as she came and almost toppled on top of me as her legs grew weak. I quickly dashed out from under her skirt and held her as she lay there in my arms, totally oblivious to her surroundings. It took her quite a while to settle down and come back to earth. I saw her eyes grow wide as she realized where we were.
"Oh my gosh! Did we really do this?"
"Yes, we did! Shall we go to class now?"
"You go first," I said. She first straightened her clothes and she opened the door cautiously and left the building. I took the stairs and went down to the ground floor. My face felt hot and I was sweating. My voice seemed to have changed as I greeted some of my buddies. I didn't see my sister until the last class and we walked back home.
