Usually Diva Mizuki is having a lot of arousing experiences in he rown world but this time she was a guest starlet within anoteh rproject - hentai parody about the game taht you all may understand as"Portal" (or"Portal two" - not make any huge difference here). Therefore, if you used to love all her funtimes just watching on teh screen this time you will have to set some attempts and play the game which include ten levels. On each level Diva Mizuki is going to test her new sperm gun device in various ways. For example in the first round you'll need to be hasty and exact enough to provide three proper titty fucking to buxomy damsels that'll emerge from portal sites for a very short moment. Time is limited so that you nicer keep your brain sharp and prepared to act if you would like to find out what evaluation is going to be on the second level. And about the 3rd one. And... well you have it today.
