She came into the room and asked me for a massage. I knew what she meant...
"Why don't you lie down on my bed, I'll get the oil from the bathroom".
She was wearing her usual sleepwear. T shirt and thin cotton shorts with green and blue stripes.
I ran to the bathroom and grabbed the oil bottle. When I got to my room, she was laying on her stomach, in my bed.
She was so cute!! Just lying there, looking at me and smiling.
"You sure are quick!" She said.
Damn, I shouldn't be too eager to do this, she might know I enjoy this too.
"Yeah! It's just that I didn't want to keep you waiting!" Lame reply, I know.
She laid her face to the side and waited for me to get on top of her. I walked to the bed and mounted her ass. She had her eyes closed and a small cute smile on her face.
I started pulling her t shirt up her back, and as soon as I reached her shoulders I realized she wasn't wearing a bra.
"Hurry up with the oil, I'm getting cold" Ann said. So I did, I started pouring the oil in my hands and rubbing it so it became warm. I placed my hands on the lower part of her back. From there I started rubbing my hands firmly as I moved them towards her shoulders. When I reach the top I applied a bit more pressure, and kneaded her shoulder blades and back.
"Mmmhh" she said. " I needed this!"
"Glad to be of service" Again a lame reply, but all I could think of was my hardening prick rubbing on her ass.
My hands traveled up and down her back in a slow rhythm for five minutes as Ann continued to relax. She was letting me touch the sides of her breasts.
"Mmmhh! Push a bit harder, I won't break!" As she said this she lifted her arms above her head. Giving me a silent approval to what my wandering hands were doing.
"Like this?" I heard my self as my hands kneaded her shoulders and my dick pressed down on the crack of her ass.
"MMmhyeah! I like that!!"
Was she referring to my hands or my dick?? Not that it mattered. We still had an hour until my parents came back. Plenty of time.
Five minutes later and my hands started wandering lower till they reached the top of her shorts.
"I'm gonna lower them a bit so I can get your whole back" I was so hard I could cum just then. She raised her ass a bit, pushing my dick further into her crack.
"mmmhh" She moaned, more like a purr really. I started sliding my dick on her ass, as my hands went up her back and then again as they went lower. I was getting hot and she started responding by making small gyrating motions with her ass.
"Do it lower, John!" she whispered excitedly.
"I'm gonna have to push your shorts lower, ok?" I slid my hands under the elastic of her shorts and slid my body a bit back so I was straddling her inner thighs. And I pushed her shorts and panties halfway down her butt. MMMMhhh her ass looked so inviting!!
I grabbed the oil bottle and poured more oil into my hands and dropped some into the crack of her ass (an accident really ; ) ).
"Ohhhh it's cold!"
"Sorry, let me get it!" I quickly used both my hands to squeeze her ass checks and then slide my hands up the crack of her ass. I had never done this before but I was so exited I couldn't stop.
"Hey, That's not my mmm back!" Her voice broke as my finger gently slid over her anus.
"You said go lower!" Lame, lame!! But she didn't answer, instead she just pushed up involuntarily.
"mmhhhmmm, ok..k" She was now openly gyrating her ass on my hands. Her eyes still closed. The small cute smile on her face quivering slightly as she purred her reply.
My shorts were getting too small for me. So as one of my hands kneaded her ass and pleasured her anus, the other relieved me of my shorts.
So here I am straddling my sister, probing her ass, and my dick only inches from her pussy.
"This is nice!" Ann said, as my right hand massaged her back and my left did shameless things to her ass. Her shorts and panties were already down, leaving her ass on display. And as I slid my hands up her shoulders, I slid my body upwards. Letting my dick slide over the crack of her recently oiled ass.
"John mmmhhh"
"What is it Ann?" I answered without stopping my body from sliding over hers.
"I dunno about ... mmmmhhggg" As my body slid upwards again, my dick slid between her legs. I stayed still, trying to think. Is she gonna scream, should I stop? It feels so warm!
"It's just a massage, Ann. Let it work on you..." I whispered between trembling lips.
"mmmmmkkk" She was beginning to loose control. My hands were sliding up and down her back, kneading her ass and shoulders. My dick was now coated with oil that slid on her ass. And it was sliding towards her unprotected pussy.
I was loosing it, her purrs were beginning to sound more like moans, her ass was beginning this slow pumping motion, making my dick slide over her pussy lips. The touch was electric, I was about to cum.
"RRRRIIINNNGGGG"
The phone rang, scaring both my sister and me. I jumped off her and she pulled up her shorts, covering her ass from my sight.
Doing the same, I ran to answer the phone.
"Hello?"
"John? Is your sister there??" My sister's friend Tatiana. Fuck!!
"Hey! Sure, let me get her for you."
"Hey! Ann, it's Tatiana!!" I yelled loudly. Although I knew my sister was right beside me, I usually yelled for her.
As I left my sister to answer the phone, I went to the bathroom to wash off the oil. I didn't bother closing the door. I turned on the shower and stepped into the water. My hands were trembling, my dick was hard and that's when I heard my sister.
"John??"
"I'm just gonna wash up real quick, Ann!" She was standing outside the shower. I tried to ignore my throbbing hard on.
"Mmm, would you mind if I get in with you?! I'm a bit sticky myself." Ooooohhh, if she comes in here I wont be able to control myself.
"Sure!" I said.
I could see her taking her t shirt off, her shorts and then I heard the curtain. And as I stared at my naked sister, she looked straight into my eyes and smiled before stepping into the shower with me.
I couldn't help but remember my sister at my grandmas birthday party. Her long chestnut hair, big brown eyes. Her cute smile and her head slightly tilted to her left. She was giggling because my cousin Monica was chasing her brother Diego. My innocent little sister...
... who was now naked in front of me.
