Is one Ghusl sufficient after ejaculating multiple times due to masturbation, or is Ghusl required for each time?

Masturbation is forbidden, and one must repent from it. If one masturbates and ejaculates, ghusl (ritual bath) becomes obligatory. If one masturbates again before performing the first ghusl, one ghusl suffices. However, if one masturbates after the first ghusl, a second ghusl is required. Consensus has been reported that for someone who has incurred multiple impurities, one ablution suffices, and similarly, for someone who has become ritually impure multiple times, one ghusl suffices.
