(IF delusional) With an aphrodisiac after confinement... (with multiple diffs)

In a what if fantasy that has nothing to do with the main story... Tom has been kidnapped and drugged with a strange aphrodisiac!

At first his attitude is defiant, but as the drug takes effect, his heart starts beating faster and he feels his body boiling hot.

Then, regardless of my own will, the rod between my legs became swollen and erect.

At first I held back, not wanting to be used as a plaything for my kidnapper, but just touching the air felt so good... I felt a strong urge to squirm, but my body was tied up and it was difficult to change my position, even to rub against the floor. I can't even move my hands freely.

I want to experience as much pleasure as possible, so I shake my hips to stimulate my anatomy with vibrations and wind. It feels so good that in an instant, semen spurts out from the pole! It does not know where to stop and continues to overflow.

I was supposed to taste pleasure and hell until the effect of this drug wears off...

I was thinking of a situation like this.

But I'm not very good at the kind of things that are destroyed by confinement or drugs, so it's just a fantasy story.

However, I think it's very erotic to have an erection while sitting on the floor with your hands behind your back.
