Slightly different perspective bc Im not a cuck, and my parents were divorced when I was pretty young. but my dad wasn't a cuck at all.
I do remember my mom having a couple guys over on dates when I was about 7. Id received "the talk" early, so knew the mechanics of it but of course hadn't hit puberty yet. Id also read her erotic novels and my dads skin mags, so was pretty enlightened about sex, for a kid.
I remember once she had a guy over, he had a little red sports car. They went up to her room and I saw the lights go off. I felt weird about it...upset/jealous/threatened so had a tantrum and the guy left. She was pretty disappointed with me so I know she was trying to get fucked but she said they were just having a "massage". id seen her without a bra on lots of times...in hindsight, she had nice big tits, (but could have used some pubic trimming..it was before bald /nearly bald pussies were standard). maybe that's where I get my love for big tits lol. So ya, I think she wanted to get fucked a lot. Prob would have preferred to settle down with 1 guy though.
both my parents talked pretty freely about sex with me which made me feel pretty uncomfortable.my mom once said she hoped I wasn't going to have a big cock like my father as it could be uncomfortable for women. And my dad told me about how some women are "screamers" but my mom wasn't. I think divorced parents want to talk more to their kids like friends, even if the kid finds it creepy.
