My sister Beth's aspiration to get a tattoo started when Bob and I returned from New Orleans with tattoo's on our shoulders. Beth thought they were cool and wanted to have a tattoo of her own near her ankle, but our parents didn't approve, stating that only the indecent girls would have tattoos.
Other than being my best friend since the 7th grade, Bob was Beth's boyfriend. They met at our house years ago and instantly hit it off and later started dating, which became a serious affair. After High school, I started attending the nearby community college, since I was keen on becoming an art teacher one day and Bob went on to work for his farther, who had a home remodeling business. Beth is year junior to me. She just graduated from high school and waited to attend college in the fall semester then.
Beth and I got along well and our relationship even improved when she started dating Bob to the point that I didn't even minded double dating with them. Often times, when I was the driver and Beth was in the back with Bob, I knew what went on in the back. I guess it was hard not to know. Likewise they knew what I did in the backseat with my dates. Whenever Bob and Beth had disagreements, Beth always came to me asking to interfere or for counseling, so we pretty much knew about each other's personal lives.
When Beth though she could have a tattoo where our parents may not see, she went to a tattoo artist and came home with some designs in her mind and asked me if I could enhance few of them for her liking and I casually agreed, but never put much thoughts into spending time drawing the butterfly with heart in the center of each wing. After she bugged me several times, I made few designs using my computer program and gave her few printouts she wanted to get a tattoo to surprise Bob on his birthday.
While she was extremely happy with my designs, she wanted to see how her favorite design would look on her skin, using several different colors. One summer morning when I woke up to the smell of bacon and eggs, I had no idea what Beth had in her mind, till she asked if I would drew her favorite butterfly below her collar bone on the back of her shoulder. With a very satisfied stomach, I just didn't have the heart to say 'no' to Beth. So, I agreed, since I didn't have anything better to do either, and invited her to my room for the task.
"I don't want it to be any bigger than this" Beth said giving me a folded piece of paper and the design. I grabbed few ballpoint pens in three basic colors and got ready for the task as she rested face down on my bed and lowered her blouse over the shoulder.
It didn't take long to me to realize that drawing on skin was much different than drawing on a flat piece of paper on a flat desk. Straight line would look bumpy, so I decided to get on the side of the bed, stretch her skin between my left thumb and the index finger while drawing, and that yield better luck. Then I also had to deal with the tickle factor as Beth got jumpy when I touched certain areas, causing me many retries to a little patch of her skin. Once I was done with the outline, I asked Beth if she realized that our parents may see the tattoo if she wore a low-cut dress.
"Good question..They will see it, won't they" Then she thought for a moment and asked if I had any recommendations and I kiddingly said;
"Why don't you get a tattoo on your buns, so only Bob can see it" and went on to work on her skin. Second later, she surprised me by asking to draw on her cheek bellow.
"Well, are sure about this, I can try to draw. Which side do you want me to do?" I responded not knowing if she was kidding or not and her answer was "Hmm. Let's see how it turns out down there. You can do either side, it doesn't matter, I guess"
I became bit nervous about having to draw on her ass cheeks, let alone seeing it out in the open. I must also admit that also felt strange excitement, but I didn't know why. I haven't seen Beth without a piece cloths covering her rear since we became teenagers and the prospects of getting the opportunity to see and draw on them brought the strange fee that occupied my mind. But I knew I didn't want anyone, especially Bob to know that I drew on Beth's naked ass and therefore I looked for a confirmation from Beth.
"Are you sure you want me to do that, Beth?" I asked again and she articulated her desire to go ahead.
"Hey, don't worry, I already took a shower this morning, so my back is not dirty. On the other hand, are you nervous about touching me there? I am sure you have seen a pair of ass cheeks before, right? So once you have seen a pair, you have seen them all. Besides, when I go to a tattoo artist, I have to let him touch me and see me there too, right?" Beth went on...
"Alright, Sis! Your ass where I am going to drew on next. I guess you are right, once you see one, you have seen them all, so are you ready to drop your panties, Beth?"
I teased her back, covering my own nervousness and I said with a made up macho voice. I lifted her dress and rolled down her panties enough to me to draw. She laughed and stood still on the bed as I got on the bed kneeling to sandwich her thighs between mine. I didn't think it would be exciting to see my little sister's naked butts, but having them exposed in front of my face brought feelings that I hadn't had for her before. However, I stayed calm, but my dick got little excited about the outlook.
I found drawing on a well-rounded flesh was much harder than the back of her shoulder. I kept moving around be find a comfortable position where I could rest my elbows and still be able to draw. Beth stood still for the most part, but each time I changed the position, she had to move to accommodate me. This awkwardness created couple of problems. Each time she moved her butt, her panties would roll-up again, getting me to roll them down while I tried to draw, without offending Beth. Then I began to enjoy touching her smooth, curvy ass and my dick started to get aroused. Each touch brought more feelings and desires to see the rest of her ass and fondle as I wish, down to her covered pussy.
"Hey, Beth, Do you mind if I lower you underpants bit more, they are getting in the way?" I finally asked and she nodded, but didn't say anything. Without any further delay, I quickly lowered her undies down to her knees, but when that became a hindrance for her body movement, I removed them completely without asking for her permissions this time, and she did not protest.
I was having a good time playing with her ass, drawing, erasing more often than necessary, stretching her skin, and squeezing softly, of cause this was all necessary to draw. Then when I accidently dropped the pen between her ass cheeks down to the bed, I made a quick attempt to catch it, but it wound up falling anyway. In my attempt to quickly grab the pen, I made unintentional contact with her pussy and then I felt the unmistakable wetness there. I sniffed the back of my hand to make sure it wasn't sweat and I knew it wasn't. That gave me a sinister feeling. My little sister is getting wet and excited by my touch, wow.. I thought and I was getting equally, if not more excited and had a hard-on to prove it.
Therefore, the next time when I wanted to erase a line, I became bit daring and used my tongue to wed along the ink line, which made her jerk her ass, then I proceeded to use my palms to erase. "That tickles.." Beth exclaimed. Making the most out of the opportunity, I squeezed her ass cheeks, licked along a ink line and squeezed, since she was pinned to the bed and wasn't able to make much of a fuss about it, but to laugh hysterically.
"Are you done yet? I don't want to be tickled to death" she asked regaining her poise. I was almost done at that point with the design, but I went on to play by drawing slowly across her thighs, her ass checks, while keeping my face flat on her other ass-cheek, causing Beth to raise her ass and making in contact with my nose.
Then when she thought that I had crossed the line, she threatened to leave by saying "That's enough. I had it" , but I was in no mood to stop the play now. I knew she was hot and wet and my dick was trying to burst out of my pants. More than anything, it gave me pleasure just having her naked butt in front of me to me to play as I wished and therefore, I wanted to prolong as long as possible.
"Ok, ok, I stopped. I was just playing Beth."
