Just a bit of shopping

Kim didn't plan anything special, so you two go shopping a bit. First you go shop some normal clothes. Krystal didn't need anything, so Kim was the only one trying on some clothes. First she took some T-Shirts and some shorts, before you both head to the cabins. You already want to sit yourself in front of the cabin to wait for Kim to change as she looks at you and says "Krystal, don't you want to come in with me?" "Oh, sorry. I forgot!" You say and you both laugh. You both go into the cabin. You see your sister putting away the pullover and the jeans she was wearing. She was wearing a blue bra and matching panties. You couldn't see much coz she directly puts on the T-shirt and shorts. Then she looks at you and asks "And? What do you think?" "You look fantastic in it" you tell her, exactly like Krystal would. Then she looks at you "Wait here a moment, I need something else." And after a couple of minutes she was standing there with a pair of red underwear. You see as she puts away the T-shirt and shorts again. Then she opens her bra and lays it to the side, after that she pulls down her panties and lays them next to her bra. You could see her big ass shacking with every move she makes. You see her pussy and her blonde bush. And you see her nice D-cup breast hanging down, with their pink nipples on them. You love your power. Since your sister was older than you she always was aware of where you were when she dressed or undressed, not that you ever tried to spy on her. A lot of your friends always told you how hot your sister's were and you can't say anything else. Your sister then puts on the red underwear and asks you "How do I look?" "I love it" you tell her "Your tits and ass look so wonderful in this." She then puts her normal clothes back on and you two go to pay for the clothes.

After that you both sit yourself into the first restaurant you saw and eat together.
