I always had a good relationship with my sister. She is a year younger than I am, with blonde hair, blue eyes, a slender figure, firm breasts, and in great physical condition. I would be lying if I said I had never fantasized about her. She was dating a guy in my grade, and I am pretty sure that he was pressuring her to be more sexual.  He had planned a ski trip for the two of them for a weekend; my sister kept asking me to go with them.  Although I loved skiing, I did not want to take on the third-wheel role since I did not have a girlfriend.  After a little more coaxing, I finally gave in and said, I would go.  After all, it was my sister, and if she felt more comfortable with me, how could I say no? 

We had a long weekend and left for the ski resort on Friday.  My sister’s boyfriend came over to pick us up; we loaded up his car and began the three-and-a-half-hour trip to the ski resort.  For most of the ride, he talked about the condo he rented and how it had a kitchen, a living room, and one bedroom.  I guess he probably paid a fortune, which is the price you must pay to get inside my sister's pants.  When we got closer to the resort, we stopped at the supermarket to pick up food for the weekend before continuing to the place where we were staying.

Once we reached the condo, we unpacked the car and settled in.  Since I was offered a place to stay for free, I thought it would be a good idea to cook dinner for them to show my appreciation.  Following dinner, we spent some time lounging around, watching TV, and discussing our plans for the following morning. My sister appeared to be her usual self outwardly, but she seemed a bit preoccupied. I sensed she had something on her mind, yet she chose to keep it to herself for the moment.  Eventually, my sister's boyfriend said he was tired, and they both got up and went into the bedroom while I grabbed a blanket and laid down on the couch.

Later that night, I heard the bedroom door open. I was half asleep, and the glow from the television illuminated the room enough that I could see my sister exiting the bedroom.  She was wearing a cotton T-shirt that barely covered her little white lace panties.  My eyes were half shut, but I couldn’t help but stare at her perfect little ass, as she closed the door quietly behind her and turned.  I could see her nipples pressing through the shirt as she walked over to the couch and sat on the floor.  My first thought was, boy, what happened? Am I going to have to fight this guy? 

“I need your help,” she whispered.

I sat up still thinking that I was going to have to confront her boyfriend about something. 

“What happened?" I asked.

Without saying a word, she slid her hand up my leg, under my boxers, and came to rest on my cock.  Boy was I in shock!  I sat straight up, eyes wide open, staring straight at her.  Her hand was warm and soft as she started to gently brush her fingers across my meat.  I think she asked me if it was okay, but at this point, her hand was already resting on it, as it slowly started to grow hard.  She smiled when she felt it growing under her lightly touching fingers.  

“Do you need help with anything else?” I jokingly asked.

“Yeah, I do!" she said.  

Then she grabbed my boxers and slid them down, exposing my now-hard cock.  She sat there, almost inspecting it, as she looked all around, studying every inch of my penis.  I could feel the skin around my balls getting tighter as my cock grew rock hard from excitement. 

At this point, I was thinking, well, she already touched it; let us see how much further she would go.  I grabbed a hold of her hand and guided it back to my fully erect penis, and she instinctively wrapped her hand around it; she had a light touch.  Still holding on to her hand, which was now fully wrapped around my hardened pole, I started moving her’s up and down my shaft, very slowly from the base up to the bottom of the head.  She seemed to get the hang of it quickly, and I let go of her so she could freelance a little.  Her hand felt so good after a minute or two of pumping; she started flicking her thumb up slowly over the head, which made me gasp a little. My pre-cum was flowing; with every thumb flick, the leaking driblets coated my now slick cock more and more. 

“Does it feel good?” she asked.

She was stroking at the perfect speed, not too fast but at a steady pace, slowly building me towards completion.  It felt more than good; it felt amazing.

“It feels amazing,” I responded.

My cock was so slick from the precum that her hand effortlessly glided up and down the shaft, and I shook each time she brushed over the tip.  At this point, I figured, why not go for broke?  I asked her if she would lift her shirt.  Without hesitation, using her other hand, she lifted her shirt, exposing her perfectly shaped tits. 

That was enough for me, as I felt the cum-rushing from my balls into my love stick.  I moved forward on the couch towards her, and my cock started throbbing, gasping one more time, and I started shooting my load all over her tits, one stream after the other covering her chest while she continued to stroke up and down.  She waited until every drop came out before letting go, and her tits were covered in my warm cum.  She got up and got some napkins, whipping my sticky load of her tits, before using another napkin to clean my cock.  I told her that was the best hand job I had ever had.  After that, she smiled and went back into the room.

The next morning all three of us went to the mountain and skied all day.  My sister acted as normally as she always did with me.  I could tell her boyfriend was all charged up, and if he got the same hand job as me, then I would not blame him for being a little excited.  I could tell that the last thing on his mind was skiing, and his only thought was my sister's soft, gentle hand stoking his cock up and down like she had done to mine.  Everyone acted normally, and after skiing, we all grabbed a bite to eat, went back to the condo, and watched some TV before going to bed.

Later that night I heard the bedroom door open then close, and my sister was again sitting in front of me by the couch.  This time, no words had to be said; I sat up and pulled my boxers down to my ankles as my sister took her shirt off, exposing her perfect milky white tits.  She remembered how much that had excited me the night before.  This time, I took a good look at her pink areolas and the most amazing pencil eraser-sized nipples that were already standing erect. 

After last night, she already knew what to do and I felt her warm soft hand snake around my cock as she started slowly pumping up and down.  The combination of her exposed firm breasts and her gentle hand made my cock grow at an expedited rate.  I could feel the blood rushing up from the base of my shaft to the very tip.  It did not take a long time until I was hard.  Her technique was great; she would start pumping faster, getting me overly excited, and then slow it down at the right moment to not finish me off.  It was edging at its finest.

I could not believe this was happening a second time; this time it was different.  She stopped jerking and her head slowly moved down within an inch of the top of my swollen penis.  I felt warm air from her breath, heavily at first, but slowly began to subside back to normal.  I felt her tongue softly lick the bottom part of the head, then another lick followed by another as she started licking all around my mushroom-shaped tip.  Her tongue felt great as she lapped up the precum that was dripping out my piss hole, and my excitement grew with every lick.  

I felt the inside of her warm wet mouth as it closed around my rock-hard man meat as it slid down my pole, her tongue tickling the bottom part of my shaft.  Her mouth was so wet, as she slowly pushed her head down, coating my cock with her spit, and then sucked her lips tightly as she came back up to the head.  Just like the hand job, she was slow, gentle, and deliberate in her movement, which enhanced the pleasure.  I looked down, so I could watch her blond hair bobbing up and down as she gobbled up every inch. My cock was so hard as she began to increase the speed, her spit dripping down my ball sack, as she worked my shaft.  I felt that I was about to explode.

“I’m going to cum,” I mumbled.

I started to pull out of her mouth, but she pushed forward and stayed attached, not allowing me to escape her warm piehole.  I could feel the load in my balls ready to explode.  I lifted my hips, and my cock started throbbing in ecstasy, as I started shooting warm salty streams into her mouth.  She moaned with pleasure as I filled her mouth with four or five shots of my seaman. 

She waited until my cock stopped twitching before slowly pulling back pausing at the tip to give it one last suck.  After that, I received the same treatment as the prior night; she got some napkins and cleaned me up, before putting her shirt back on and walking back into the bedroom. 

To date, it was the hottest sexual experience I had ever had.  I assumed her boyfriend was about to have the best blow job of his life.  I think she just wanted to try it on me first so she would be more confident with her boyfriend.
