From Studio Sakura, i knew 4 games (marina 1st, mayumi 1&2 and Plz bang my wife) who have been translated, but i just found out that there are 5 marina's games, and a bunch more with different characters (same NTR thematic throught) in japanese sadly
One day i'll hope someone would be able to translate them ! One man can dream
Our pc is in the main hall bro, that's why I can't play on pc, as for phone i can play safely in my room that's why
Also, if you really can't play the game, (and you're actually 18+) i may have an alternative solution for you ... Since there isn't much to play in the game, it's mostly a narrative game, you cant watch it as a video ... on your phone ...
If you were to type something like "Marina no "Netorase" Houkoku" on some celeb navigator or others .. sites ...
I'll let you do the math from here ...
