The name suggests it is likely an indie adult game or, more critically, a potentially malicious file. Because it is an unverified .rar archive from an unknown source, you should exercise extreme caution:

: Files with sensationalized names in compressed formats are frequently used to distribute malware, trojans, or ransomware .

: If you are looking for adult simulations, it is much safer to use established platforms that scan files for viruses and provide community reviews.

: Do not download or extract this file. If you have already downloaded it, run a full system scan with updated antivirus software before attempting to open it.

There is no credible or widely recognized software review for a file named Masterbation_Simulator_NEXT.rar .

: There are no listings for a "Masterbation Simulator NEXT" on reputable gaming platforms like Steam, Itch.io, or Nutaku.
