Cheating on husband

A couple months after my first gangbang sandy had a new boyfriend. He was giving tattoo's for extra cash so I went to her house to get one. It was only me sandy and Jim and after tat was done we had a couple drinks and hung out. Sandy had other plans she started rubbing my leg and kissing me. It felt weird with hubby not with me but I liked sandy a lot. What I didn't expect that Jim walked in room naked and walked over to us the next thing I knew sandy pushed my face toward his cock. I knew I shouldn't have but I opened my mouth and took his cock in my mouth. That when sandy said to Jim I told you she is a slut. My pussy got so wet hearing her call me that. She got undress while he used my mouth the she said let's go to bedroom. When we got to her bed she sat in chair as he undressed me. Then he laid me down and started licking my pussy while sandy masterbated and watched. I asked her to come join us but she said I was to be Jim's slut for today. While he was licking my pussy I kept thinking that my husband would be so mad with me doing this behind his back, but his tongue felt so good. Then he climbed on top and slid his cock in and he was much bigger than I normally get. Then he started teasing me by just putting tip in and said he wanted to hear me beg for it. I looked at sandy and she said if you want it beg for it. I was a little embarrassed but I said fuck me please then he slammed it in. We fucked for about twenty minutes til he was ready to cum when he was ready to pull out sandy said cum in her. When he was done and climbed off I went to wash up but she handed me my pantys and said if I want anymore in future I had to go home used. So I ended up going home used and when I got home hubby was waiting for me. Apparently him and sandy planned this so I climbed on top and let him fuck my used pussy. By the end of night I got even I made him clean two loads out .
