It's a BL visual novel called Kichiku Megane. There's a partial english patch which you can find a link to on vndb, but the project was dropped. Fair warning though if you want to play it, it's pretty graphic, lots of rape, some blood and violence, bdsm, group sex etc.
What manga is in the last image? (After togainu no chi)
