This load had really built up for a long time and desperately needed to come out.
You can clearly see how thick the semen had become.
The pre-ejaculate clears the way, then the clumps come out, and then the cumshot follows.
It usually doesn't smell and taste so great after all that time.
I know this from personal experience, and I only release such old loads into my pad, unless a woman is really horny and absolutely wants to swallow it 😅
