Shower Glory Hole

My 18 year-old step-sister had come to stay with us for the summer. She was a year younger than me and exceptionally HOT! And, she knew it. She had flirted with me (I think) a couple of times when her mom wasn't looking. I played it cool, but was VERY interested in pursuing something.

I just happened to catch her getting dressed a couple of times, putting her bra and panties on, when her door was open a little. I wondered if she hadn't done that on purpose, just to get me turned on.

The first time, her naked body was turned to directly face the door opening, giving me full view of EVERYTHING! She cupped her tits before slipping the bra-straps over her shoulders. They were just the right size, firm and with nice nipples. They always seemed to be erect when I was around. Weird.

Before she slid her panties on, she spread her legs and ran her fingers through her pussy hair, parting her pussy lips with one finger, closing her eyes and raising her chin skyward. She seemed to enjoy touching herself. It certainly was a huge turn-on for me, but I was sure she didn't know I was there watching her every move. Her pussy was covered with a triangle of soft pussy hair, trimmed at the edges. I REALLY wanted to bury my face in that!

The second time, she was getting ready for a date with her boyfriend Frank. He was several years older than her, in college and I was certain she was fucking him PRETTY regularly.

Again, she was completely naked, with her door open about 6 inches. She stood in front of her mirror, which gave me a view of both her front and her gorgeous ass curves. I couldn't help but slip my hand into my pants while I watched.

She put both her hands over her head to fix her hair up. This raised her tits way up high, which was always a huge turn-on for me. Then, she slid her hands down her neck, past her shoulders to her tits. She looked down at them, cupped them, then pressed them together. After pinching and playing with her nipples a bit, she slid one hand down to her pussy and started fingering herself with her eyes closed. At one point, she opened her eyes, and I was SURE she looked RIGHT at me through the darkened door opening and made the slightest of smiles.

She turned and went through her drawer to find a pair of panties to put on. Once she had slid into them, and turned to face me so she could examine her ass in the mirror, I could see they were beautiful lacey crotchless panties! Her pussy lips and hair pushed out of the opening begging to be handled! I was furiously rubbing my cock, with pre-cum sliding all over it at this point. I stepped back and came just as she was covering up with a slinky black dress. Well, if he knew what was UNDER that dress, he could surely have a good time tonight most anywhere: at the dinner table, at the movies or in the car driving. I was pretty sure she would somehow let him know early in the evening the "opening" he had and could take advantage of.

A few days later, no one was home but us and Kelly said she was going to take a shower. A little later I heard the water running and thought, that sounds pretty loud. I ran up the stairs and saw that Kelly had left the bathroom door 3/4's of the way open. Her clothes made a path to the shower, ending with her panties and bra in a little heap by the shower curtain.

I had an idea. I opened the drawer slowly and carefully, so as not to make a sound. She couldn't hear much over the shower water flow anyway. I found a small scissors and crossed to the middle of the shower curtain.

I cut a very small hole in the middle of the plastic curtain, just below waist high. When I peeked through it, I could see her entire naked body. She was lathering herself up from her tits to her pussy. She seemed to be rubbing her tits pretty hard. Then she moved her hand down to her pussy and worked her soapy hand all around that area. She moved it between her legs and slid her fingers in and out repeatedly. I could see by her face she wasn't just washing her body. She was finger-fucking herself!

I started cutting the hole slightly larger, until it was about 2 inches in diameter. I knew she wouldn't hear the quiet sound of my cutting because she had her eyes closed and was entirely focused on working her pussy. Her pussy was extremely wet, not with water or soap, but with flowing pussy juices. I could tell she was very turned on but no matter how hard or how fast she rubbed, I could also see she was getting no closer to getting herself off. I was pretty sure she would be open to what I was about to try.

I stood up and pushed my rigid cock through the hole in the thin shower curtain. I just stood there and waited for her to open her eyes and notice.

It took a moment, but then, I heard a small gasp and I knew she had seen my cock, throbbing and bobbing with excitement. She wasted no time crossing the shower. She must have run her hand up and down her wet pussy, loading it with the slippery stuff because she gripped my shaft and slid her hand up and down once to lube me, then lifted one leg and stepped over my cock, positioning it between her legs and up against her hot pussy.

I wasn't even inside her but it was so wet and hot and soft, I just about came right then, but then she moved her hand down to hold my cock and started to push it up inside her. She moaned as I entered her, sliding all the way up inside her, in one motion.

I pulled at the shower curtain on both sides of her, ripping it from the hoops, two feet on the left and two feet on the right, leaving only the center still attached. I moved my hands around her waist to grip her ass-cheeks through the shower curtain, pressing it against her backside. I pushed up, through the hole in the curtain and up into her needy pussy as she ground back against me, the shower water splashing everywhere.

It felt strange and very different, but also good, in a weird way. There was something about not being able to see one another that intensified the experience.

We both came in about 15 seconds, simultaneously. My shrinking dick pulled out of her body and I pulled back out of the shower curtain glory hole. She pulled the curtain from between us, and said "Oh it's you, Tom. I thought maybe it was my boyfriend Frank. But, your cock is SO much bigger than his. That was amazing! You won't tell him will you?"

"No, it will be our little secret. I really liked fucking you though. Do you suppose we could do it again sometime? Maybe without the shower curtain?" I asked, hoping against hope that she would agree.

"Yes, I suppose that could be arranged. To be clear, I don't let just any Tom, Dick or Hairy into my pussy. But, I DID have an extreme need tonight and your huge cock met my need perfectly. I REALLY enjoyed it! Just so you know, though, after having sex, my body doesn't get turned on again for about another 15 hours, so you'll have to wait until then. Are you OK with that?"

15 hours? I was thinking it would be a week or at least a couple days before she might want to fuck me again but: "Yeah, I can make that work. It's a date. I will look for you in 15 hours." I'm not sure I would even sleep at all in the next 15 hours, just thinking about it!

I set a timer on my phone for 15 hours later which put it at four in the morning. I was quite certain that I would be sleeping soundly then so figured that this would have to wait till tomorrow sometime but I was wrong.

Exactly at 4 AM, my bedroom door squeaked open. Kelly was standing there with lacy panties on, and nothing else. She crossed the room in the dark, slid under the covers, pushing up against my side. it was the nicest wake-me-up I had in my life, even if it was four in the morning. She pinched my nipple, then ran her fingers down my stomach and slid her hand inside my underwear, surrounding my already, rigid cock. When she realized I was dry, she retracted her hand, slipped it down inside her panties slid it up and down her dripping slot, and then brought it back to my cock. She spread slippery pussy juice all over it. It smelled musky and turned me on even more, if that was possible. She rolled away from me a bit, wiggled her panties off of her hips, down her legs, down her long legs and off in one motion, then tossed them onto the floor. She had my underwear off in a flash, to join hers in a little heap.

Quickly, she rolled over and straddled my hips, reaching between her legs, grabbing my cock and positioning it so she could slide down onto it with her pussy. She moaned as it slid all the way into her and started rotating her hips and grinding her pussy into my pelvis. It only took her about 30 seconds to cum. It happened so fast I didn't realize it was over. She hopped off me, winked at me and said, "Thanks bro." Then she grabbed her panties off the floor and slipped out the door.

As I lay ion my bed with my dick throbbing between my legs, I thought Hell no!! She wasn't going to just use me to get off and leave me hanging here, hot and heavy.

I got out of bed, completely naked and quietly exited my room, went down the hallway and pushed open her door. As she saw me enter her room with my huge bare dick bouncing in front of me, her eyes grew large.

She had put on a clean pair of panties, so I bent over her and hooked a finger under each side of them, and yanked from off. "Turn over!" I whispered. "And put this pillow under your belly."

She did as she was told and now her ass and pussy were pointed at the sky and towards me, I knelt on the bed and positioned myself directly behind her, between her legs I slid my fingers between my pussy lips, rubbed up and down her hot wet slot, brushing her clit with each stroke. She arched her back and pushed back against my hand so I knew she was getting into this.

I pushed my cock between her legs, rubbed it in and out against her slippery clit and wet soft pussy lips. Then I found her pussy opening, still loose and open from the quickie sex she had just had, and slid my cock deep inside her. She grunted with passion as it pushed in further and further.

I held her hips and found a good rhythm sliding in and out, my thighs and balls slapping her ass with each thrust. The speed naturally increased as I neared my orgasm. As I shot my load, deep inside her, I reached around and pinched both of her nipples. As I did, so, she came again beneath me, grinding her ass cheeks back up against me. (So much for needing 15 hours before cumming a 2nd time!).

I leaned back pulling my cock out of her cum-filled box, and as I got off the bed, I slapped her beautiful ass, looked down at her, winked and said "Thanks sis. Let's do this again sometime. Maybe in 15 hours?"

She groaned and rolled over on her side as I left her room.

I went back to my room and slept like a baby the rest of the night, as short as it was. I dreamt of all the times we would be together again and what we would do together. It was going to be a great, HOT summer!
