I was out with the guys having a couple drinks mostly chatting at a club one evening. I had arranged to leave early catch my girlfriend at her place once she got home and showered from work. I had just planned on a nice intimate evening with my girlfriend but out with the guys we made conversation with other tables and tried our luck flirting and dancing with the girls. My single friend hadn't any luck giving up trying to pick up for a while. I kept dancing and soon was having a last dance before I had to leave with a lovely younger lady. I told her i have to go. she looked at me funny and after a short pause said she was here to look out for her mates and didn't want to ditch them. I was confused giving her a look. She must have misheard me with the loud music that Id asked her if she wanted to go somewhere?? I'm trying to work out what she thought I said when she then asks did I drive in?? I said yes. Next thing shes suggesting we could drive somewhere private for a bit and come back. I kept my mouth shut realizing what was happening finally.

I told her to wait outside while I told my mates I was going. I actually tell my mates Im leaving as its time to head back to see my girlfriend. I'm in shock at what's happening as I lead this girl to my car and start to find a private place to park. As i drive I fully start to realize my girlfriend will be expecting me in a short while. I feel terrible about what i'm doing but i cant tell this girl i'm not interested as I very much am. I find a spot to park and as shes getting in the back seat i have to message my girlfriend im stuck with my mates still and am running late before she calls worrying about me. I still don't stop getting into the back seat making out touching and due to my small back seat doesn't led to sex but her giving me a blowjob. She doesn't seem very keen on it but she thought my car would be bigger and says i can make it up to her later. Whilst shes in the middle of sucking me my girlfriend messages me back telling me no worries and have fun xoxox. I tell the girl its my mates telling me to have fun. She giggles and finishes what she started.

Afterwards I tell her we better get back and I offer to drop her off near the front of the club as its getting cold and lie that ill go find a park. By now i'm so guilty i drive straight to my girlfriends place hating myself worried and scared i've ruined my relationship. Once I arrive at my girlfriends she can tell i feel terrible and im not in a good mood. I'm worried she will talk to my mates and ask about me and in turn my girlfriend will find out. She tries to be intimate but i insist on a shower and then go to lay in bed she joins me and we kiss a bit but im not my usual horny self and i have to say i'm tired and feeling down. Not to be put off my girlfriend says i know what will make u feel better kissing down my body and starts to give me a blowjob. I feel bad but I cant refuse that offer. I am thinking of the girl in the club and now my girlfriend doing this to me. Looking over at the clock I realize its only been an hour and a half since the other girl was doing the same thing to me. I start to enjoy the feeling and I don't feel as worried anymore and before long I start to feel like a really lucky man. Before long my girlfriend has me rock hard and i'm telling her not to stop thinking of the girl in the club and her both sucking me and me cumming in both their mouths. Best night of my life but to this day I still feel terribly guilty sometimes living with the secret.
