Seducing my stepson

I married for security and a better life going forward. My husband was 52 at the time of our marriage and I was 27, He was a widower and already had son 28 by his first wife. his son was a great disappointment to him. He believed his son to be gay. It was the main reason he married me wanting to have another child. I knew his son wasn't gay, he was a nerd very smart and into reading studying and playing chess. I saw his son looking at girls not boys and realized he was just really shy around females. His father dominated his life and had hindered his emotional development growing up. He didn't play sports but exercised in the home gym. I saw him exercising without his shirt on and he was all muscles. I'd grown up watching Kung Fu movies with my late father who idolized Bruce Lee, my stepson skinny body flexing his muscles looked like Bruce Lee flexing his muscles. My stepson also learnt martial arts. Didn't show off or enter competitions, so his father never saw him as more than weak and nerdy and most likely gay. Married and eager to provide my husband with an heir, but fate had other ideas. I still wasn't pregnant after 6months. Then my husband had a car accident proving he was a real man not a wimp like his son, he was in a coma for several days before passing away. Now a widow and not pregnant and strong prenup in place. I'd two choices take the little I would get and find another rich husband or seduce my stepson. I chose my stepson, two reasons mainly I got on fairly well with him and I knew he like to look at me in my bikini. I reasoned bedding him would be easier than finding another rich man like my late husband. I thought it would take a month or two, but it took three days after the funeral. First two was sitting by the pool ion my bikini, third was walking into the gym in my bikini and asking him to put lotion on my back. Normally I would hold mu top over my breasts while string at the back was undone and the lotion applied. But I let slip and he got aroused and like the saying goes strike while iron hot. Needless to say, we fucked and spend the night together and everyone since, my stepson was very eager and I was very willing. Of course, I got pregnant and we married out of state. Fortunately, my late husband didn't parade me around like a trophy, he kept our marriage quiet, waiting until I got pregnant, sadly I never did for him. So, now married to the son and pregnant, people we met put two and two together and assumed we were always married. We don't correct them, quite happy with our new lives together.
