Way befor I was married I was seeing/fucking an older(41) happily married gal with a family. Her husband had no idea. We had an almost every Thursday deal at my place after work. She openly told me she liked what we had going and after she'd leave my place she would have sex with her husband. She kinda jokingly said he liked their Thursday night sex. I don't think we could call that cuckold.
Different married gal, we were both 23, she was happily married and pregnant. Her and hubby lived 3 doors away in my apartment. She was about 4 months when we started, she was super horny she said because of being pregnant. I fucked her whenever I was home, she didn't work. 3, 4, 5 times a week, sometimes two visits in same day. Hubby didn't know about us. She openly told me they had a great sex life and had sex often. There was many times hubby left for work at 7:30, she'd be at my place 15 minutes later. She'd tell me they had sex befor he left. Other times we'd have sex just befor he got home. I know I had his seconds many times and he got mine. I don't think that's cuckold. I was always scared to see him but I guess he never found out.
Different girl, we were both 22. She had a boyfriend she said she loved. She was fugley, crooked teeth but had a killer tight body. It went one of two ways, she'd call and bring pizza or Chinese over around 7, we'd eat, watch a movie then have sex 2 or 3 times, she'd leave. Or she'd call around 11-11:30, from his place using his phone. She'd stop by my place and we'd have sex for a couple of hours. She stayed the night a few times. I got his seconds many times, I don't thing he ever got mine. I know that's not cuckold.
