I fucked my wife's friend for cheating

I was in office and my wife is also in the same location. So we often have good talks and her best friend also works in the same city so we 3 have met many times over weekends for pubs and movies. Her best friend has seen my pics, our sex videos and has a desire for me but never made it obvious till last Sunday. On 15th December, I planned for a movie and bought 2 tickets for us. But my wife ditched me so I ASKED her best friend just casually. She accepted out of the blue and it was a planned corner seat. I never had any feelings for her but she's damn hot and she is better than my wife in every way. We met and we watched the movie. Initially we just got friendly and nothing more. But there was a small kissing scene and I got horny. I was wearing pajamas only. My best friend mistakenly touched me there while teasing me that your wife isn't here during such scene.... She was awkward but I didn't mind because mistakes happen. She after sometime again touched me to see if I was still big. She did it 6 to 7 times and I asked are you okay? I am little horny and I think you know it. she said *I have always seen your pics and videos from my wife's phone and she's down for me. So I asked her to do as she wants to and have my dick. She didn't hesitate for a second and put her hand in. She handjob it while I kept my hand on her shoulders. She suddenly bent down and gave blowjob for 5 to 6 minutes and I was about to cum but didn't. She then got normal and we again watched the movie. But after movie, I went to her apartment and fucked her with her consent without condoms and cummed inside twice which she wanted for fun. She promised to keep it a secret and it's been 2 days only but I am worried. That's how I cheated.
