My Sister Lisa

Lisa 23 was out of work and with no skills, unlikely to get one anytime soon. I'm her older brother Gilbert 28 and got myself set for life by chance in a lottery win 5 years ago. I didn't have enough money for a night out and so bought a lottery ticket which won. Average prize at best, but it was great for me and I didn't have work shifts anymore and paid off my parents mortgage and also a new car and a new car for my sister as well. Lisa had a job in a diner and then it had a fire, when oil in the kitchen caught fire. Lucky no one was injured, but the diner was to badly damage and was torn down. Lisa lost her job and after trying everything to a job, turned to me. I live on 5 acres away from the rushing of the city. I have a dog and nothing else and date and get sex every now and then. Lisa came to stay and hangout for awhile, but we went out on the town together and really smashed it. Drunk out of our minds, I awoke next day in the hotel room we were booked into with a naked woman beside me and didn't see her face at first. I headed for the bathroom first as I was busting to pee. Returning I saw the woman's face it was Lisa, I was shocked at first. But unsure whether or not I had sex the night before, I checked over Lisa to see if there was any sign of her having sex and saw what looked like sperm around her pussy and also coming out of her pussy. I rang for room service to get something to eat. As the fog lifted off my brain I remembered having sex on returning to the hotel and it was with Lisa. Now sure I had fucked her, I waited for her to wake up. When she awoke about hour or so later, she went straight into bathroom peed and then got straight into the shower. I took off the robe I was wearing and joined her in the shower. She didn't say anything, but looked a little puzzled I was showering with her. As we showered together, I asked did she remember last night and most importantly. What we did on getting back to the room, she wasn't sure at first what had happened. But it came back to her, thinking she would be shocked like me. But she just said you fucked me and what you want to fuck me again now. I was shocked that she didn't think it was so bad a brother fucking his sister. I just looked at her and she added might as well, you were pretty good last night. Then she took hold of my cock and it went hard, so we fucked again. On returning to my place, she asked me did I want her to sleep with me, I nodded and ever since we been sleeping together. She still hasn't a job, but lets me fuck her anytime I want and I've started to want her a lot. I've recovered from the shock of fucking Lisa and now think its great.
