Keywords: mf, spank, peeking, nosex
Summary: Tiffany shows off for Brian and nets a spanking

Tiffany and I have bedrooms that share a bath at one end of our house; our parents have their own bedroom and bath on the other side of the “public rooms” – the living room, kitchen and dining room. This gives our parents much-needed privacy; I know they need it because on some occasions I’ve been in the kitchen and heard happy lustful sounds from their bedroom. TMI, but it’s good to know they have a happy marriage. “Mom” is Tiff’s birth mom and my mom at heart, as Dad is my birth Dad and has raised Tiff as our own.
The privacy of our parents was just how things were until I discovered that my sister enjoyed being spanked, enjoyed spanking me, and had both voyeuristic and exhibitionist tendencies. I had needed something like a minute to get past the initial “ick” factor and become her enthusiastic partner. The layout of our house meant that Tiffany and I could move easily between our rooms while our parents were in their own room. We would probably make too much noise to conceal our activities if we indulged each other while they were in the living room. But we would be quiet enough to stay off their radar if we waited until they were in their room or were away from the house.
This period of our lives lasted several years, a thread through our normal lives of school, dating, activities and growing up.  There were many, many times that we enjoyed our game. We were romantically interested in others as we grew and we both married happily. Tiff and I remain close, though, closer than many birth brothers and sisters. In private talk, we have shared how our teenage hobby became part of our adult relationships. The story here occurred in the summer when Tiffany was twelve.
Tiffany had startled me at the end of her sixth-grade year with a request that I should spank her as Dad had spanked her. I had enjoyed the experience thoroughly. She had also taken the opportunity to spank me, something I had doubts about but I found I enjoyed that as well. You can backtrack to find that story if you like.
Several weeks after our first spanking episode, I drove Tiff to the pool so we could have a cooling swim and our parents could have a few hours to themselves. Tiffany was very attractive in her bikini, a white suit with a floral pattern. Her breasts were still a suggestion more than a statement, which was fine with me. Her body remained a little angular but her bottom was nicely rounded and her thighs also. You know how it is with many girls in their earliest teens.
We enjoyed a couple of hours at the pool and returned home. I suspect our parents had enjoyed our absence in their own way; Mom’s hair was a little disarranged and they were happy in a distracted kind of way. We had a standard family evening – “How was the pool?” “Oh, I saw a couple of cute guys,” “Tiff, you’re too young for that, Brian, did you see any girls you liked?” We watched a couple of TV shows and headed for bed around 10. “Can I have first shower?” Tiffany asked.
“Sure,” I said. “But leave a little water for me, okay?” Tiffany’s fondness for longer showers had left me with only tepid water many times.
“It’s too hot for a long shower,” my twelve-year-old minx said.  She scooted off to her bedroom and I went to mine to read before my own shower.
I was reading on my bed, a perfectly good boy and model older step-brother, when I heard Tiff in the bathroom and saw the bathroom light under my door. The water started running and I could hear Tiff’s movements in the bathroom. To my surprise, I also saw my doorknob turn and the door open slightly into the bathroom. “Tiff?” I asked. “Something you need?” Maybe she had just realized she needed a towel or shampoo.
Tiff was silent and I heard the shower door open and close. Obviously she had cracked my door before entering. I moved quietly over to the door and I saw that, open a short way as it was, it offered me a view of the mirror in the bathroom. I could see the blurred shape of my sister behind the shower door (it was a shower-tub combination).  I went back to my bed and continued reading. After about ten minutes, a short time by Tiff’s standards, I heard the shower stop and the door opening. A moment later, my bathroom door moved a little more open.
I moved back to the door. As I expected, I could see Tiff in the mirror as she began to dry herself. Her breasts were small and pert. I really liked her nipples. They were pink, a little large for her breasts, and very, very tight. This was the first time I had seen breasts like this, but I had seen Tiff’s nipples at times under her tops and I knew they were often pert. I also knew they were far taller now than I had seen before.
I caught a glimpse of Tiffany’s eyes in the mirror. She had confirmed to herself that I was peeking, using the invitation she had given me by opening my door. She smiled a moment and then acted as if she were alone. She patted her body down with her towel lightly to stop the dripping water. Then she worked her hair with the towel, leaving her body naked. Her skin was lightly tanned and she had bright white breasts and pubic area like her bikini. She made some sort of excuse to herself to turn around and I could see her pretty round bottom as she continued to dry her hair. She even bent over at one point to dry her legs and feet. Then she turned back to face the mirror and draped her towel around her shoulders.
Tiff got her hair dryer out and turned it on. She spent several minutes drying her lovely red hair. Her towel draped over her breasts but left her otherwise naked. I could easily see her pubic area and her completely bare mons. I spent a lot of time looking at her soft fold of skin between her legs. When she would move, this area would open a little. It was a fascinating sight for a boy who had seen only the cross-sections in health books. Even on so small a child-woman as my Tiff, this area was beautiful.
Tiffany finished drying her hair and put on her sleeping outfit. This was a pair of panties and a nightie just long enough to cover them, both in pink gingham muslin. The bathroom smelled of shampoo and body wash, clean and sweet. Tiff glanced in the mirror once more, winked at my reflection, and went into her room. She closed her door properly.
I took my own shower, although I left Tiff’s door normally closed. After I dried off and put on my sleeping shorts, I went back to my room and closed the bathroom door. I read for a while, until I heard a slight sound. I could see the doorknob from the bathroom turn slowly. The door moved silently and opened enough for a narrow view into my room.
Tiff must have forgotten to turn off her bedside lamp or some other light source in her room because I could just make out that she was kneeling or crouching behind the door. I knew perfectly well what she was waiting for. I stretched as if I were sleepy. Then I got my box of tissues and knelt on the floor. I put some tissues out so I could cum on them and keep the floor clean. I knew that Tiff was watching these preparations and I thought she wanted me to know she was watching. This only made me more excited and I took my shorts off to reveal a truly magnificent hard-on, if I say so myself.
I began to stroke my cock a little and to caress my glans.  My cock twitched in response to my touch. I continued to stroke and to rub my penis between my hands, a rolling motion that I enjoyed greatly.
After about five minutes, I stood up without cumming and I slipped my shorts on. I heard a little sound behind the door and I looked toward the bathroom.
“Tiff,” I said, “I know you’re there. Come on in.” Tiffany came into the room, her hair in braids, her nightie flouncing a little. The light in my room was low but I could see her very clearly and enjoyed the sight. I sat on my bed and Tiffany came to stand in front of me.
“Did you like my show?” she asked me.
“After your shower? I liked it a lot. I figured that was what you were doing with the door.”
“Well, you are teachable,” she giggled. “I loved your show. Why did you stop?”
“Because you were watching. You’re a naughty girl again, Tiff.”
My little sister went into “naughty Tiff” mode at once. She put her hands in front of her, just at the hem of her nightie. She looked down as if she was embarrassed but she was looking up at me under her eyelashes.
“Yes, Daddy, I’m naughty again,” she said. There was a high blush on her cheeks.
“What should I do with my naughty little sister?” I asked her, holding her hand.
“Daddy should spank his naughty little one,” she said slowly. Slowly but eagerly.
“How should I spank you?” I asked her. We were learning to build a ritual.
“You are going to spank me on my panties,” she said. “A bunch of times.”
“Yes, I will spank you on your panties,” I said. “And after that?”
Her blush was brighter. “Then you are going to pull my panties down. You’re going to spank me on my bare bottom.”
“Yes, I am,” I said. “Over my lap, with my bare hand on your bare bottom.” She nodded and giggled.
Tiff stood by my right leg and put her hands behind her, over her bottom, which emphasized its shape. I lifted her slightly to pull her over my lap and she fell into position. This time, instead of having her bent at the waist with her knees just off the floor, I pulled her right up onto the bed across my lap. It seemed a very comfortable arrangement for both of us.
Tiffany looked over her shoulder as I pulled her little nightie up. I could see her panties even with her nightie in place but this exposed them more completely and a large strip of skin on her back as well. I could actually see the tan line from her bikini top. “How bad have you been?” I asked as I rubbed her twelve-year-old bottom on her panties.
“I’ve been kind of bad, Daddy,” she said. “Daddy” was the cue to put some sting into my hand. I gave her ten pretty good spanks this way. She was kicking her legs and finally said, “Brian, I’m naughty,” which was the cue to soften up. I spanked her with love-pats for another fifteen or twenty spanks, by which time she was just about purring on my lap.
“Naughty girls get their bare bottoms spanked,” I said. She knew that already but I thought she would like hearing it. Tiffany nodded and I pulled her panties down slowly. I enjoyed it very much as I saw more of her little bum and finally had it all exposed.
I gave her only soft spanks on her bare bottom, even after she said “Daddy” a couple of times. But after about forty love-pats, I told her, “Naughty girls have to learn their lessons.”
“Yes, Daddy,” she said. I put my arm over her back in a kind of hug. Then I gave her ten firm spanks, enough to make her bottom a little pink.
“Girls who take their spankings like good girls get a treat,” I said. I rubbed her bare bottom for five minutes or so and I was rewarded with an arching back and a wiggling set of hips. I finished by tickling Tiff for a minute or so, making her laugh and squirm before I pulled her panties up.
I helped Tiffany squirm around to sit in my lap and I gave her a hug. She hugged me back and kissed my cheek. “Daddy, I’ll try to be a good girl now,” she said.
“I doubt that,” I answered.
“Daddy, I have a question. You just spanked me so hard for watching you play with yourself. But you stopped playing with yourself and I already got spanked. So do I get to see you finish playing with yourself?”
That seemed somehow only fair and it gave me an idea. “Yes, Tiffany, you got spanked so you should get to do what you got spanked for.” I stood up, lifting her like a little girl, and I put her on my bed. “I want you to lie on your tummy,” I said. She giggled and complied. I pulled her nightie up again so I had a good view of her panties, which I left in place.
I knelt on the floor and re-arranged my tissues. Staring at my little step-sister’s legs and panties, and looking sometimes at her eager face, I pulled on my cock a few times. Then I started rolling it between my palms in one of my favorite ways to play with myself. In a few moments I was spurting a very forceful, very large amount of cum onto the tissues. My shoulders shook and my hands trembled as my audience of one clapped her hands softly.
“Oh, Brian, that was worth a spanking,” Tiffany laughed. “That was one of your good ones, I can tell.”
“Yeah, it was,” I said when I had my breath back. I used the tissues to clean up. “Now it’s bedtime for you.”
I pulled my shorts back up as Tiffany sat up on my bed. Her nightie fell back into place. “You know what I’m going to do when I get in bed,” she said slyly.
“I bet you’re going to play with yourself,” I answered.
“Yes, I sure am. Are you going to watch? Or are you going to peek?”
“What’s the difference?”
“If you’re going to watch, you come right in and sit by my bed. If you’re going to peek, I’ll leave the bathroom door open a little and you’ll watch from in there. I’ll like it either way. But I want you to peek, like I do with you.”
What else could an indulgent big brother do? Tiffany walked ahead of me, very cute as her bottom twitched. Her panties peeked just below her nightie. I stopped in the bathroom and we arranged the door. Tiffany went and dove onto her tummy on her bed. She turned her face so I could see her big eyes and her smile. Both hands disappeared under her tummy and a moment later her bottom, still in her panties, wiggled vigorously.
After a few moments of this, Tiffany squirmed to raise her nightie and expose her breasts. She pressed them into her quilt and moaned quietly. Then she used both hands to push her panties down so I could see her bare little bottom again. Her hands returned to her tummy, or rather to her pussy, and her whole body got into the act.
In a few moments she held her breath for a long time, then made an O of her mouth and moaned softly again. Her body became very rigid and then relaxed with a completeness that indicated her satisfaction.
Tiffany smiled and winked at me. I smiled at her, nodded my approval, and closed the door. I slept very happily that night, dreaming several times of my sister, my spanking buddy, my toy.
