First Time With My Sister

I had just moved in temporarily with my big sister and her family while I was deciding what my next move would be.

My sister was 40 and I was 36.

They had a guest living room and bedroom in the basement which I was occupying. My sister and I had also grown up to be every close.

I was sitting in the basement when I happened to look out and see my sister working in her garden. I went out to talk to her when I noticed she was wearing a very lose tank top without a bra and she was bending over quite a bit. I thought "COOL" I can get a cheap thrill by peeking down my sister's shirt and seeing her firm little tits. She knew what I was up to and started purposely bending over in a fashion where I can get a straight bee line shot down her shirt. I got an immediate erection as I watched her firm little breasts wiggle about and she took notice with a look of approval. We continued to hangout talking until she had to go in and start dinner. The vision of her delicate small breasts remained in my mind for the rest of the evening.

Later that night after everyone was asleep she came down to smoke a cigarette with me. She was wearing a flimsy little white t-shirt that barely had enough material left to cover her large nipples. Again I got a hard on that wouldn't quit. I was wearing very loose shorts so my boner was quite noticeable. I don't recall how we got on the topic of sex but we did. Then she confessed that she didn't think there was anything wrong with a brother and sister having sex as long as they were of age and it was consensual! I almost blew a load right then! I placed my hand on her inner thigh gently rubbing her and looking at her I admitted that I always wanted to have sex with her. She reclined back into the couch pulling down her panties as I got on top pulling my throbbing penis out and thrusting it into her. We had to be careful not to be too loud so nobody hears us but I was pounding her like it was the first time I ever had sex and it was in a way too, it was the first time I was having sex with my SISTER! We both held each other tight as we reached an orgasm together my cum squirting deep into her as she moaned and sighed with a detection of delight.We had to catch our breath after that it was so intense.

Then she pulled her panties up, looked at me and said "We'll do this again" as she was heading upstairs to get back into bed with her sleeping husband.
