Alright, Fran, let's take a look at that temperature….what are you doing?

The stepfather had opened the bedroom door without warning, thermometer in hand, and clearly didn't expect to find what he saw.

Fran, red as a tomato, quickly tried to cover himself with something, change position, do whatever it took to make the stepfather think he hadn't noticed that he was masturbating, but it was useless because he had seen it perfectly.

Fran was left speechless, didn't know what to say, only stuttered..."I...nothing, I wasn't doing anything..."

Well, I didn't expect this, son. There's no need for you to make anything up or give me explanations, I know exactly what I saw, and I also know that at your age it's something natural, although in your condition you shouldn't be doing it because it weakens you even more. Anyway, this indicates that there are some conversations we need to have. Because you haven't talked to your mother about this, have you?

Fran made a face like "how was he going to talk about that with his mother or anyone..." and said a very quiet, almost inaudible "no".

The stepfather put the thermometer on the table, saying with a half-smile that if he took his temperature now it would be too high, but while his temperature normalized, he would take the opportunity to do a small examination that he hadn't done before because he didn't think it was necessary, but now it was. That he should stay still on his back in bed and pull down his slip.

Fran didn't pull down anything and wanted to tell him that there was no way, that he wasn't going to let him see him like that, still erect, but he also couldn't speak. The stepfather, with a serious face, pulled down his slip and told him not to be ashamed, that it was something natural and that he knew he couldn't control getting like that, although what he did have to learn to control were the urges to touch himself and hold back.

He started examining Fran's penis and testicles, touching them, holding them gently and squeezing them a bit but without hurting him, he uncovered the penis, moistened his hand with saliva, and kept touching it, while Fran tried not to express the mix of shame and pleasure he felt, and while he touched him, he asked if what he had seen was something he did habitually. Fran said no, never, but the stepfather looked at him very seriously, made masturbation movements himself that excited Fran even more, and told him not to lie, that he wasn't stupid and wouldn't be fooled.

Fran confessed that he did it every day, even several times a day, and the stepfather replied that he believed that more, that he would let him have a moment to calm down, but no touching himself, and that he would be right back, and left the room.

When he returned, Fran's erection had passed, but he almost had a fit when he saw the stepfather enter with a syringe already prepared in one hand and a cotton ball in the o...
