My Sister Is All Grown Up Now

I had been away at college for two semesters. So, when I came home for summer break, I discovered that a few things had changed. For instance, my kid sister Jenny had somehow morphed into a hot chick. I thought we had been close before. But that summer we got closer than ever.

When I walked into the house, I was greeted by my mom and dad. Then this sexy chick came up and hugged me. I literally did not recognize my sister at first. While I had been completing my freshman year of college, she had turned 18, graduated high school, and become a woman. I remembered her as a skinny, flat-chested tomboy. Now she suddenly had boobs, hips, an ass, and some very nice curves. As she hugged me, I started feeling some feelings that I probably shouldn’t have felt for my sister.

She was barefoot, wearing short shorts with a crop top showing off her trim midsection. Plus, her hair was longer, wavier, and blonder. My sister looked like a whole different person. But underneath, she was the same girl I had grown up with.

I didn’t get to see much more of her that day. Mom and Dad kept me busy as they caught up on my college activities and fed me dinner. Eventually, I retreated to my room to unpack and unwind. I was pretty tired after the drive from campus. So, I took a shower and sacked out on my bed to watch some TV. Later, my sister came in to visit.

I had left the door ajar, indicating that I wasn’t doing anything private. Jenny rapped her knuckles lightly on the door as she swung it open and walked on in. She was dressed for bed, wearing the same kind of oversized T-shirt she had slept in since she was a kid. This one was tighter and shorter than I remember. It stretched taut over her breasts and let her thick nipples poke into the soft material. The shirt wasn’t too long either, barely covering her crotch and ass, showing off the full length of her long shapely legs. I tried not to stare.

We chatted about what we’d both been doing the past few months. She wandered around my room occasionally bending over to check out some of my stuff, showing a glimpse of her bare butt. Either she was wearing a skimpy thong, or nothing at all under that shirt. Jenny finally plopped down on the lower corner of the bed. My eyes kept being drawn to her chest, her hips, her legs, her hair. She had to notice me looking. Eventually, I felt like I had to comment.

“Looks like you’ve really filled out lately,” I said awkwardly.

“I know, right? I was beginning to think I’d never get boobs. Then boom! I got all this.” She gestured up and down her body. “Mom even made me go on birth control a few months ago. Just in case, you know.”

“Probably a good idea,” admitted.

“I haven’t done anything yet,” she said looking away shyly. “Not really. I mean, I’ve messed around with a couple of guys, but I didn’t let them get very far.” She put her hand on my bare thigh and leaned toward me like she was sharing a secret. “Some of my friends talk about how their first time was weird and painful, and they wish they could do it over. I want my first time to be with someone I know and trust. Someone I’m really comfortable with, you know?”

“Sure,” I said, “Sounds like you’ve given it a lot of thought. Are you thinking of anyone in particular?”

She smiled, and lazily trailed her fingertips across my leg. “Yeah. I just have to get him on board with the idea.”

“I can’t imagine any guy saying no to you.”

“We’ll see,” she said standing up and tugging her shirt down. “I’d better get to bed. You’re probably tired anyway. Maybe we can hang out by the pool tomorrow.”

I was about to reply, when she leaned down and kissed me. It was on the cheek, but near my mouth. And that was something she had never done before. Then she turned, and left, closing the door behind her. I got up long enough to lock the door and turn the light out. Then I masturbated thinking about my sister’s body.

The next morning, I slept late then spent some time putting away my college stuff and organizing my room. Mom and Dad had already gone to work, so it was just Jenny and me for the day. I went across the hall and knocked on her door without opening it.

“Hey, I’m going out to the pool,” I told her. “Are you coming out?”

“Yeah,” she replied through the door. “I’ll meet you out there.”

I went back to my room, put on some trunks, and grabbed a towel. Out by the pool, I pulled a couple of chairs into the sun for us. I have to admit, I was looking forward to seeing more of my sister’s new body. But I had brought a book along as a distraction. As a 19-year-old guy, I had a lot of erections about a lot of women. But last night was the first time I’d had one over my own sister. That kind of bothered me and kind of excited me. In fact, as I lay there thinking about it, I felt my cock beginning to stir to life again. I tried to cool down before Jenny came out.

Just zonguldak escort then I heard the back door and turned to see my sister wearing the skimpiest bikini I have ever imagined. It was literally a few pieces of string and three small triangles of cloth. It was the kind of swimsuit that would almost certainly come off if she attempted to actually swim in it. As she approached, I said out loud what my brain was thinking, “Wow.”

She struck a mock model pose and asked, “You like?”

Instead of actually answering, I asked her, “Do Mom and Dad know you wear that kind of thing?”

“Of course not,” she answered spreading a towel on the other chair. She also turned the chair opposite of mine so we could have a face-to-face conversation. “But Mom and Dad are not here right now. And I want to get a good all-over tan.”

I marveled at her beautiful body. She had always had a pretty face, but now everything matched. The previous year, her physique had been fairly boyish. Now she had curves in all the right places.

She arranged herself face down on the lounge chair and reached behind her to untie her top. That didn’t seem very necessary since the string was so thin it was almost like fishing line and couldn’t have made much of a tan line.

“Oh, dammit,” she exclaimed. “I forgot to put on lotion and I’ve already undone my top. Would you put it on me? I don’t want to burn.”

“Um … okay,” I said hesitantly.

She handed me the lotion and I began slathering it on her starting at her shoulders. Her skin felt so good. Smooth. Soft. Warm. My hands slid smoothly all over her back and around her hips, then I skipped down to her legs.

“Don’t forget my butt, and between my thighs,” she directed. “I really don’t want to get a burn there.” She spread her legs a bit to allow me greater access.

I hesitantly spread the lotion up the inside of her thighs and over the beautiful round cheeks of her ass. She made some “mmmmm” noises under her breath. That and the feel of her skin was making my cock hard beyond my control.

When I finished, I lay back in my chair. She turned to retrieve her lotion and saw my erection tenting the front of my swim trunks.

“Looks like you’re enjoying yourself,” she commented, pointing her eyes at my crotch.

“I’m sorry,” I said laying my book in my lap. “I … sometimes I can’t control that.”

“Don’t worry, Bro,” she said. “It’s kind of a compliment. If I can turn on my own brother, I can probably have that effect on any guy.”

“I’m not sure that’s a good thing.”
“It’s cool, dude. I’m planning to be very careful. I wouldn’t be dressed like this at a public beach or pool. This is just because I trust you and I’m comfortable around you. And I’m sure you wouldn’t do anything that I wouldn’t want you to do.”

We soaked up the sun while I tried to read my book. But Jenny’s ass was right there, and my eyes kept drifting. After about twenty minutes, she stirred and began to turn over.

“Hey, you don’t mind if I leave my top off do you?”

While I was deciding how best to answer, she turned over and pulled the tiny top off, laying it to the side. And there were my sister’s beautiful breasts on full display just to my left. If I leaned forward a bit and reached over, I could have touched them. She decided to lotion up this side herself. But it was nice watching her rub all over her body, her legs, her stomach, her boobs, her arms. When she finished, and lay down, she spread her legs and angled her knees to get some sun on the inside. This gave me a good view of her crotch and the narrow strip of cloth covering it. I could see smooth pink skin on either side. The upper part of the cloth was really low and I realized something.
“Hey, do you shave?” I blurted out without thinking. I was immediately embarrassed, but she didn’t seem to care and knew exactly what I meant.

“With this suit, I kind of have to,” she explained. “Besides, it’s kind of a trend these days. Plus, I understand it makes oral sex more enjoyable for both parties. Do you find that to be true?”

“Ummm…,” I stumbled.

She looked a bit irritated and chastised me, “Dude, you’ve got to get past this. Your sister’s hot. We’re both adults. And we can talk about sex.”

Jenny had become more mature in mind as well as body.

“Of course,” I agreed. “I just have to get used to it.”

“Your cock’s hard again.”

“Dammit.”

She smiled, closed her eyes and lay back to enjoy some more sun. I held up my book and stared at her boobs.

When we’d had enough sun, we went inside, had some lunch and decided to watch a movie before our parents got home. We took turns in the shower and met in the family room. I wore just an old pair of gym shorts and a T-shirt. Jenny came in with a similar outfit and plopped down beside me on the couch. While zonguldak escort bayan we watched, she got cold, retrieved a blanket and covered us both.

She threaded her left arm though my right arm and put her head on my shoulder. Her right hand ended up on my thigh, just below my shorts. I tried to ignore it, but my cock noticed anyway. She idly ran her fingertips up and down my thigh, going a bit higher each time. She edged slowly up inside the leg of my shorts. I wasn’t sure she knew what she was doing and wanted to think it was just an unconscious movement. But soon, her fingertips were nudging close to my balls.

“Jenny…,” I started to say.

“Shhhh…,” she interrupted.

“What are you…,” I started again.

“Shhhh…,” she interrupted again.

Her fingertips grazed my balls, and my cock was as hard as it has ever been. The loose shorts gave it room to expand and the blanket kept it out of sight. Then she reached further in, cupped my balls, and began gently kneading them.

I must have made some kind of contented noise.

“You like?” she asked, squeezing a big harder.

I gasped slightly and answered cautiously, “Well … yes.”

Just then I heard the front door. Mom was home.

“Kids!” she called, “I’m home.”

“We’re in here.” Jenny called to her but did not move her hand away from my scrotum. I felt a moment of panic knowing Mom would be in the room momentarily. I hurriedly made sure the blanket covered everything that was going on.

“Hi guys, I was thinking we could order pizza tonight if you want,” she called stepping through the door. Then she stopped, seeing us cuddled on the couch together under the blanket. “Awww. Its so nice to see you too being affectionate with each other. I’m going to get cleaned up. Carry on.”

As Mom left, Jenny looked at me and smiled. “You heard her. Carry on.”

“I don’t think that’s what she meant.”

“Maybe not, but it’s a good idea.”

Giving my balls one last squeeze, she pulled her hand away and behaved herself. The rest of the evening was normal family time, aside from occasional knowing glances from my sister. I went to bed early that night and masturbated thinking about Jenny’s hand on my balls.

The next morning, I wasn’t sure what to do. The parents were at work, and we were alone in the house again. And every thought in my head was about my sister’s body and how she had been acting since I got home. Maybe she just liked teasing me. Maybe this was just another, more adult level of one sibling teasing the other. Maybe she had no intention of doing anything like her actions suggested. Maybe I was reading too much into it. Still, I decided to stay in my room and watch TV and not think about my sister or sex or any of the sexy things my sister had been doing.

Soon I heard the shower running and thought maybe Jenny would be going out for the day. I was okay having the house to myself. Maybe I’d watch some porn and work off some sexual energy so I wouldn’t be thinking about my sister all the time. So, I relaxed on my bed and started a non-porn movie while I waited.

Eventually, I heard the shower shut off. I expected Jenny would go back to her room to get dressed for wherever she might be going. But instead, there was a quick rap at my door, and she came in wearing only a towel, and combing her wet hair. She looked so hot.

“Hey bro. What are we watching?” she asked as she sat down on the corner of my bed.

It was an old movie that we had both seen a dozen times. I didn’t think she’d want to see it again, but she said, “Oh, I love that movie.”

She tossed her comb on my desk and climbed into bed beside me. I was kind of sitting with my back against the headboard. So, she lay down crossways and ended up laying her head on my stomach, with her hand resting on my abdomen. My eyes trailed across her bare shoulders, down her towel-covered body, to her barely covered ass, and along her long legs to her bare feet.

Her fingertips moved gently through the hair on my abdomen right along the waistband of my shorts. I could feel my cock rising. From her position, she had to see it. She knew what she was doing to me. But I still wasn’t sure what her intentions were. Her fingers found their way under my waistband and began to slowly slide inside my shorts. She didn’t touch my cock right away but slid past it to again cup my balls.

I took a deep breath when I felt her gently squeeze.

“Dammit, Jenny. If you’re just teasing me, you’ve got to stop. I can’t take it.”

She rolled her head toward me and said, “I’m not teasing you. I’m seducing you.”

I wasn’t sure if she were serious or if this was part of her teasing. She turned her head back toward my tented shorts. Her hand gradually moved up, letting her fingers trail up the shaft of my cock. After a few moments, she escort zonguldak wrapped her thumb and forefinger around the base of my shaft and gently, slowly, stroked me up and down.

“I don’t have a lot of experience with this,” she said. “I was hoping you would let me practice on you.”

“Practice?” I asked, beginning to breathe heavier.

“You know.” Her voice was softer and quieter now. “So, I can learn what guys like. And maybe I can figure out what I like as well. I want my first time to be with someone I love and trust. That’s you.”

“Jenny…,”

“Stroking your cock is making me wet. Is that normal?”

She stopped stroking long enough to push my shorts down. I lifted my hips to help her, then kicked them off entirely.

“Oh, you look good,” she cooed. “I’ve never seen a real live cock this close up before.” She sat up and turned toward me. “I want to suck on it for a while. But I don’t want you to cum too quick. Can you hold it, or let me know when I need to back off?”

I was in too much of a daze to construct a coherent sentence, so I just nodded enthusiastically.

She moved around to the foot of the bed and crawled up between my legs. Her left hand gently held my balls, as her right hand wrapped around my shaft, and her mouth descended over the head of my cock. The feeling was incredible, and I began to suspect she had more experience than she let on. In my head, I just kept repeating, “Oh God, my sister was sucking my cock.” She stroked and sucked and squeezed and it was the best thing I had ever felt up to that moment.

I was about to tell her to slow down, but she seemed to sense that. Pulling her mouth away, she eased back on her stroking until her hand was barely making contact. She just kept staring at my cock and balls, like she was taking it all in, learning, imprinting it in her mind. Eventually, she pulled her hands away, stood up, loosened her towel and tossed it aside.

There she stood. My beautiful sister, completely naked in front of me. Then she crawled up onto the bed, straddling my hips. She held herself in place there and looked into my eyes. “I want to be on top for my first time, so I can be more in control. Later on, you can fuck me. But this time, I want you to just lay there and let me do all the work.”

“Can I touch your boobs?” I asked politely.

“Wait till I get going,” she told me. “Then you can. But be gentle.”

She took hold of my cock and guided herself down onto it, very slowly. My cock wasn’t exactly porn-star sized. It was about eight inches long, but not real thick. Still, I loved watching it disappear into Jenny’s pussy. It slid in easily, but she went slow, lifting herself up and down, taking a bit more with each stroke. I couldn’t read her face. It looked like both pain and pleasure mixed together. She increased her rhythm and her breathing, lifting herself straight up and down on my shaft. She started making noises that I’d never heard her make before. She kept bouncing faster until, she stopped. Her eyes squeezed shut tightly. Her mouth was wide open. Her whole body shivered, and she let out a groan of pleasure.

“Holy fuck,” she exclaimed without opening her eyes. “I’ve never felt anything like that. I mean, I’ve masturbated plenty. But it was never like this.” She shivered again, then looked at me and said, “I thought you wanted to touch my boobs.”

“I was enjoying the show so much, I just forgot.”

“Well, you’ve got another chance, because I want some more.”

She started bouncing again, and I took her breasts in my hands. They must have been C’s, and they had big, thick nipples. It was hard to hang on to them while she bounced, but they felt good in my hands. I reached around and squeezed her ass, letting her boobs bounce free. Then she stopped and let another orgasm wash over her.

“Fuck,” she said, looking down at me. “I could get used to this.” Then she lay down on top of me, pressing her body against mine. She kissed me on the lips and pushed her tongue into my mouth as she started moving her hips. Riding me hard now, she was going at it so fast that I was a little concerned we were going to break something — like either my bed, or my pubic bone. But God, it felt good.

She pulled her tongue out of my mouth long enough to ask, “Are you going to cum now? Do I need to do anything different? Is this good?”

“Oh God it’s good, Jenny,” I growled as I started cumming inside her.

“Oh, I can feel it,” she said continuing to pound on top of me.”

“Oh God, yes,” I roared pumping squirt after squirt into her.

Eventually, she slowed to a stop and just lay on me, still impaled.

“That’s the first cum I’ve ever had inside me, and I’m glad it was yours.”

“Me too,” I agreed.

She sat up a bit to look me in the eye. “And can do this all summer. Think of the things we can try. I want to suck you. I want you to lick me. I’m not sure about anal. But, there are tons of different positions I want to try.”

She kept talking about what she wanted to do, but I wasn’t entirely listening. My head was full of endorphins, and I was looking forward to the rest of the summer with my sister Jenny.
