How my ex cheated and I learned I liked being cucked [cuck perspective]

I was fresh out of a relationship and had matched with a girl off tinder. After we met we had realized an undeniable sexual chemistry. We literally broke her bed our first night meeting and I wound up having to fix it and try to break it every night after that for about three months. She was 30 5’9” maybe 120lbs with little nice tots and a tiny spankable ass. Long dark hair and honestly was just built like a model.

After spending more and more time together we got more serious and I wound up spending more time at her house than mine because she had a daughter and it was more convenient and stable.

One week when her daughter was with the father I had come home a few hours early from work and came in the house but she wasn’t around. I went upstairs to where the bedroom was and heard the obvious sounds of the bed creaking and her moaning.

As I peaked in I saw the older married neighbour pounding her into the bed. I watched knowing I should burst through the door but instead I just watched his fat cock pump in and out of her tight pussy until he finally buried it and she begged him to fill her.

I snuck out of the house and waited up the street until I saw him leave and went in to see her only wearing her robe. She was very obviously nervous but I kissed her deeply and played off like I hadn’t seen anything. I licked her pussy and told her how turned on she must be because of how wet she is.
Full well savouring the taste of this guys cum in my girl.

That night she slept early and I read their texts and her telling him about me licking her clean and laughing. They talked about repeating the following day. Soon she was going out on girls nights while I watched her daughter. Every single time she’d come home freshly used.

So much happened but it was an awakening for me.
