Sister can't get enough

I (23) got back to my apartment and my little (17) sister was home for the weekend. I started cooking dinner and she walked in to the kitchen and said, "hey buddy." We chatted for a bit about our day; she's in high school. I'm a grad student. I finished cooking and said, "hey, you want something to eat?" She said, "sure, thanks." I asked her, "what do you want?"<br><br>She only said, "meat." I asked, "who are you, Ichigo?" She said, "who?" I said, "Bleach. Nevermind." I made her a plate with 2 pork chops and a baked potato. I said, "this good?" She said, "looks good." I walked her home with the plate. She looked at me and said, "hey buddy, you can come in and watch some TV with me. Want to?" I said, "sure." <br><br>I watched her eat and then she turned on a porn documentary. It was weird and I said, "what is this?" She said, "porn." I said, "oh; you want to watch porn? Together?" She said, "yeah, I thought maybe we could do something." I said, "what?" She said, "just something." I said, "well, if you want I can tickle your tummy."<br><br>She said, "yes!" I pulled up her shirt and pulled down her bra. I didn't even get to tickle her before she exploded in nipples. She shivered and squirmed on the couch. She started to moan and I covered her mouth. I said, "you can't be too loud, buddy." She said, "sorry." I tickled her some more and she climaxed again. I was a little worried. I said, "hey buddy, you okay? You seem pretty sensitive."<br><br>She said, "yeah, I'm fine." I said, "okay." After a little while, I asked, "hey buddy, how many climaxes do you think you can have if I keep doing this?" She said, "I'll have as many as I can." I said, "okay." I ended up tickling my sister 9 times before we finished watching the documentary.
