I'm looking into spicing things up with my current girlfriend sex wise. We have amazing sex and she's adventurous but I want to get her more out of her comfort zone. I want to have 3somes, swap partners and go to sex parties. I've told her about this and she seems to be open to some things but the timing has to be right and she needs to feel comfortable. I totally understand that and I'm not pushing her.

In our friend group, one of the ladies is having a "fun party," where they have sex toys, lubes, books and movies to use and buy. I know a few of the ladies and their boyfriends/husbands and I've played with them in the past so I thought of an idea.

I talked to the husband of the host and told him about my girlfriend and trying to get her to do more and asked him if him and his wife would want to play with us. Also, get the others in our group to play. He thought it was a great idea and within 30 minutes, everyone was on board, five couples, including my gf and I. My plan was to crash the party and start the real party.

My girlfriend was a bit nervous about going because she was the newest one in the group but was also excited about seeing new toys. I don't her to not be surprised if things get a little wild and it would be a good opportunity to push her envelope. She was curious and told me she'd go with the flow.

While the girls were enjoying the party, us five guys got together and talked about what could and would happen. I told them they had free use of my girlfriend, as long as she agreed. About 10pm, the host's husband got a text, telling us to come over.

All of us guys, in our 30s, were all horny and probably hard when we arrived. Before we went inside, we could already hear moaning. I was really excited because I could hear my gf. She was moaning like I'm fucking her hard from behind.

When we walk in, it's a sight from every guys porn fantasy. Five naked women in various sexual positions. I could see my gf, on her hands and knees, getting fucked from behind with a large strapon by the host. I could see the lust and pleasure on her face.

The other three guys went to their ladies while the host's husband and I stood there and watched. Once my gf finally noticed, she was a bit embarrassed. I just smiled at her and started to get undressed. When my hard cock was out, she smiled big.

"Bring that cock here and put it in my mouth."

I was surprised but extremely excited to here her say that. Right before I went down to her, the husband stopped me and said, "I got this."
