a party with my slutty gf and her friends

With my GF Lia we organized the birthday of one of her friends, let's call her Cassy, Cassy wanted to party so we did, we agreed to meet at my house on Saturday and go out all night, Cassy invited her best friend (let's call her Nicole) so they both stayed at my house.

Before going to the party, we drank a full tequila between the 4 of us, to get drunk and get in the mood, then we ordered a cab to get to the party, which was 10 minutes away from my house.

Once there Cassy told the guard that it was her birthday, he asked for her ID and went to talk to the organizer, to our surprise they gave us free entrance and 2 shots of tequila per person.

There were a lot of people and we were very drunk, I started to joke with my girlfriend that she didn't dare to kiss Cassy and Nicole, my girl loves challenges so without hesitation, she did it, this made my dick pretty hard, so I told her to continue kissing them (it seemed like they had always wanted to kiss each other like that).

Then, the party got better, they brought out a foam machine and with my girlfriend we started dancing in front of it, we all got wet from the foam so I took off my shirt (there were several guys without shirts, so I had no problem) my girl tried to take off her thin top but she couldn't, so I just touched her big tits over the top, I don't know at what point we got in the middle of a group of guys, my girlfriend knows that I love her being a slut so she started to stick her ass to the guys to provoke them, one took the initiative and grabbed her by the waist to bring her closer to him, She looked at me like a slut in heat and started to dance with him in front and me behind, I started to touch her tits and she let out slight moans, without realizing it my girl was masturbating us both while the foam ran through our bodies, I'm not lying, for me I would have fucked her right there.

Then Cassy arrived with her friend Nicole, who were slutting around, Cassy went to dance with my girlfriend and I was behind my girl again (I love to feel her ass while she dances), out of nowhere I felt hands running all over my abdomen and pectorals, it was Nicole, Cassy's friend, who was behind me, she touched me all over, even my dick over my pants, then I turned around and started to dance behind her, while her hands wrapped around my neck, I touched her tits under her shirt and I felt how she was carrying her ass more towards me.
