"Bioshock Infinite"? No, it is "Biocock Intimate"! The interactive hentai parody which throws away all the shooting and story and leaves nothing but the couple of main characters willing to do just one thing together - they want to fuck! And just like it was in the original game you will be enjoying the whole process from the male character's perspective while the beautiful Elizabeth will be taking proper care of your main gun in many different ways. And regarding the professional level that she will be doing that you can say what exactly she was interested in when she has learned to open those portals or whatever those things were... As for the controls then your favoirte button will be 'A' - use it to switch from one scene to another. But ofcourse there will be some secrets hidden as well.
Really great looking and at the same time plain to play (at least in comparsion with the original videogame) hentai themed parody where you will finally get the chance to not only save Elizabeth but to fuck her in many - almost two dozens (!) - different scenes! Use R and A buttons to switch between those scenes and you will observe from first perosn perspective how playful Elizabeth can be when she has a nice trunk in her palms, how good she is at fapping and sucking it, how passionate she looks when she rides on top of your trunk and so on - just be sure to take your time and enjoy each of these scenes which has a lot of details sending you back to the original videogame and thanks to that put the immersiveness of hentai parody games on the new level!
