After the divorce, my mother started dating a gentleman, a cultured and educated man, a high-ranking official, who had two sons. One was older than me and lived abroad, and the other was almost my age. This one, Fer, was a tall, 1.87 cm, and slender, dark-haired, with piercing eyes, a bit of a beard, and undeniable charm. He was a bit of a show-off who usually dressed informally in Levi's jeans and Vans t-shirts and had great success with women. He was a charismatic, handsome, confident guy, a bit conceited but also friendly and fun; he had a girlfriend now, but he had had many adventures and loved women, and he never missed an opportunity to flirt with a beautiful female and her attributes.

After my mother's passing, her partner - Fer's father - left for abroad with his other son, so I ended up living with Fer, since although we hadn't lived together much, after the incident, he kindly invited me to stay at his place to get through the tough time.

He was handsome, had a sense of humor, was charismatic, knew it, and knew how to take advantage of it, although now he couldn't even remember the names of many of the women he had fucked in many ways. He even had the opportunity to have a threesome with two women. He loved dirty sex, beautiful women, even if they were older, "deep throats," and he would drool and get excited at the sight of any woman with sinuous curves, especially when everything was visible and he imagined eating her pussy, giving her a fuck, or squeezing her ass.

We got along well, we chatted a lot, played Xbox, but he did his own thing, was very independent, always busy with his own stuff and prioritizing those dates where he could unwind and have a good time.

One day, I was feeling pretty bad, with a sore throat and general discomfort, and he offered to take me to one of his uncles, a doctor, who examined me, looked at my throat, prescribed some medication, and told me that his wife - a nurse and Fer's aunt - would give me an antibiotic.
