Normally Diva Mizuki is having a lot of arousing adventures in he rown world but this time she was a guest star in anoteh rproject - manga porn parody about the game taht you all may understand as"Portal" (or"snare two" - perhaps not create any huge difference here). So if you used to enjoy all of her funtimes just watching on teh display this time you will have to put some efforts and play the game which include ten levels. On each level Diva Mizuki will test her fresh sperm gun device in various ways. For example in the first-ever round you'll have to be swift and exact enough to give proper titty fucking to big-chested chicks that will appear from portals for quite a short moment. Time is limited so you better keep your brain acute and ready to act if you would like to see what test will be on the 2nd level. And on the 3rd person. And... well you have it today.
