Camping trip pt2

As my sister ran away and around the corner I'm thinking what is happening, She my sister I really shouldn't have these feelings. I pull myself together and walk around to the front and head in. I go in the front door I and hear the shower still running runnning. My sister in her room. I sit down on the couch thinking about whats been going on today.I hear sis open her door. She in her little shorts with the shirt with the sleeves cut out. She sits down on the other end of the couch I see her small firm tits throught the side of her shirt. I still can remember the shape of her little mounds with puffy nipples. She says you know Lucy likes you.I'm thinking to myself if Lucy like me so much and your her friend what are you doing to me. She pulls her shirt acrossed her chest and said you don't like seeing my titty's? Lucy turns off the shower My sister jumps up and walks over to the bathroom and opens the door Lucy jumps and covers herself wraps herself in a towel. My sister walks on in leaving the door cracked open. I can see the whole bathroom. My sister takes the towel from Lucy and turns her so I can see her whole body relecting in the mirror. She starts dry her back rubbing up and down over her ass down her legs. Handing her the towel back she pulls her shorts down and sits down on toilet. Lucy continues to dry off running the towel over her breast and they snapping back up in place as she works her way down drying stomach water dripping off her pubic hair. My sister daps herself stands up pulls her shorts up and walks out leaving the door cracked again. Watching Lucy reach for her panties on the sink and starts putting them on. My sister walks and sits straddling my lap, she wraps her arms around my neck leans in and said you like her better than me. We hear our parents pull in. My sister calmly kisses my cheek gets up and pulls the bathroom door closed as she walks back to her room. She walks back out as our parents come in. She has put on a differant shirt, Its her cheer belly shirt. Mom say are you k**s hungery? Dad said I'll go to the store and pick up some meat you start the rest. Mom walks in the kitchen and opens up the frig and gets what she needs. Lucy finally comes out and ask mom if she needs any help as she walks in the kitchen. My sister walks out and sit down on the couch with her back to the kithen. She looks back into the kitchen looks back and pulls her shirt up exposing her tits to me and mouths to me do you like these. I mouth back at her stop before you get us in trouble. She giggle a litlle. she lifts her feet up putting them on the egde of the couch making her shorts ride up slpiting her pussy lips like she did in the car. This time she starts to rub her crotch pulling her shorts over kepping her pussy covered with her hand. I can take it anymore I stand up and say I'm going to lay down for a while come and get me.I go in and lay down and close my eyes and amost immediately My sister pops into my thoughts I already have a hard on and now its getting worse as my hand hand finds my dick. I start to slowly stroke myself as I think about her . The way she has no fear, she is exposing herslf to me with our mom standing ten feet away. How she stroke me outside after she catches me watching Lucy in the shower. The way she straddle me and rocked back and forth on my dick after she came out of the bathroom. I have to stop my didk is starting to hurt it I havent had my dick this much ever. I hear mom tell sis to go wake me up and be nice about it. I hear the door open as she walks in. Im laying on my stomach when I feel her lay on top of me pressing her body against mine. Its time to eat. She gets up and starts out. I said tell mom I'll be there in a minute. I went outside to the picnic table. I sit across from my sister I ask her to pass the hamburger. Mom says how are you k**s enjoying the lake. I say Im having a time Ill never forget. Looking at me my sister says I agree I hope we can expore more while we are here. Mom said you k**s can do anything you want here your on vavation.My sister looks across and with that smile I feel her feet on mine then it starts running up my leg I feel her foot run up and down my dick. My eyes get big with the pressure of her foot pressing against my dick. I get up and go back in the cabin to watch some tv. After a while mom and Lucy and sis clear off the table. Mom says lets play a board game. Dad goes over and pulls out the game and sets it up in the livingroom floor. We play a few games when I say Its time for me to go to bed. I go in my room then I hear mom and dad start to go up the stes and sis and lucy go to their room.
