Just had my longest orgasm yet last night (Expectation is the key)

Last night I want to have a very quick session while I only had one day abstinence only.

But it was the strongest and longest orgasm for me ever, so not having expectation is really matter.

The climax had lasted at least 25 min while I was listening to one binaural audio twice on Youtube:

ANAL And GENITAL Stimulation – Binaural Ambience Music – Meditation Vibes – Strong Isochronic Tones✔

Seem like different binaural audios also matter.
