If you want to produce ASMR content you should see to removing any background noise. In this one and a few others I’ve watched the effect is totally destroyed by this. In this it sounded like a washing machine was running.
Thats the right way to let a man really enjoy his orgasm! Slow right down as he starts to ejaculate. Firm but gentle pressure with your mouth and just let him PULSATE and enjoy the sensations of his orgasm! Savor the beautiful warm taste of his cum, let him grunt as he ejaculates and shares his cum with you! Then swallow it for him as he comes back to reality
