I (f) turned 33 on Saturday. I had nothing special planned. The hubs and I were going to do dinner with my brother and his new wife.

I’ve been dreaming about my new SIL since the cameltoe picture incident (that story is on my profile).

I was pretty pampered all day. I showered and was getting ready when my husband gave me a funny instruction. He had worked out a surprise and told me to dress in comfy clothes and go to my brother and SIL’s house.

I assumed she and I were going to a spa or for a massage.

I drove over and she greeted me at the door and invited me. I didn’t see my brother, just her. She walked me to her bedroom and we sat down on the edge of her bed.

She told me she got the ok from both our hubbies to have some fun together. She said she’s been dreaming about me since the wedding.

My husband and I were super freaks. We love sex and trying lots of different things. Kids put a damper on time and space, so we’ve been pretty humdrum the past few years.

I knew my brother was a bit of a playboy, but I didn’t know where my SIL Caitlyn was with all of it. Now I know.

We helped each other strip down. She’s tall and slender with olive skin and A cups. I am short and a little thick. I was super self conscious but she made me feel comfortable and pretty.

We kissed, then she sat me on the edge of her bed. She worked her way down and ran her tongue around my nipples. She was so delicate and perfect. I was so turned on.

She kept heading south and had my scoot back on the bed. I laid back as she bent forward. She ran her tongue right up between my lips and made little circles around my clit.

It was ecstasy!

She worked me for a minute and popped her head up. She asked if I minded company. I smiled and said ok, not expecting what happened next.

“Babe, come in here,” she shouted. I looked to the door and my brother walked…naked and hard as a rock.

We all burst into laughter and I grabbed a pillow to cover my face which turned red from embarrassment.

He said hi and told me happy birthday. I felt Caitlyn go back between my legs. I uncovered my face and realized why she was bending forward to eat me and not with me on the bed.

My brother was fucking her from behind. This went on for another minute or two. I lost all inhibition and care about who was in the room.

My brother backed out of Caitlyn and crawled next to me on the bed. He stayed on his knees as he inched closer. I grabbed his cock, wet from his wife’s pussy, and began to suck it.

Another thirty seconds went by and I heard my husbands voice. “How bout one more?”

I looked up and in came my husband Dave…naked and hard. I was still holding my brothers cock as Dave walked up behind Caitlyn. We all were laughing.

Dave mounted Caitlyn. I went back to sucking my brother Dan’s cock while Caitlyn continued to eat me.

We passed each other around laughing and enjoyed each others bodies with no regard. The mini orgy ended with the boys spraying Caitlyn and I with their thick loads while we sat on our knees in front of them.

We cleaned up and did go out to dinner. Best birthday yet!
