Jerked off every morning while vacationing with my sister

I saw my sister naked a dozen times last week.

My (m28) sister Annie (f33) called me a couple weeks ago. She was taking her two daughters on a trip to the Bahamas and asked me to join.

My sister is divorced. She had a gal-pal going with her who backed out at the last minute. She told me if I bought a plane ticket down, everything else was already paid for.

I work remote, and the place we were staying had a business lounge. I bought a ticket, packed my bags, and met Annie and my nieces on the island.

She had a suite for the week. It was two separate bedrooms, each with its own bathroom, and a living room in the middle. My nieces had one room and my sister and I had separate queen beds in the other.

We had beautiful weather and a great week bumming from beach to beach. It was a perfectly normal week except for one crazy scene.

My first day there we played in the water all day. We came in to get changed for dinner. The girls went to their room l, and Annie and I went to ours.

We both went to our suitcases to get clothes. I assumed we were going to take turns changing in the bathroom, but Annie stripped out of her one-piece bathing suit and got dressed right in front of me.

On average, for my week there, I was seeing her naked twice a day. She would be changing and talking to me about family stuff or the girls school. I have to assume she thought nothing of it because we are siblings.

I had never had a sexual thought about her before. She’s my sister. I’ll be the first to tell you she is beautiful and has a great body. But now I was seeing her in all her glory and I was hooked.

I beat off in the shower almost every morning.

I have lots of bikini pics to commemorate our trip, but her naked body with the blue sea through the window behind her will live in my mind forever.
