DISCLAIMER: I OWN ABSOLUTELY NOTHING!!!!
I only added the subtitles to the video.
Original Video: 【腐向けAPH】ま.ぶ.た【兄.夫.婦+α】
Original Translation: ’Daiji na Mono wa Mabuta no Ura’ by Kokia
“Iindesuka“ by Radwimps
They artwork for the first vid is of great quality not common in MADs. The BMG for the second vid is just too catchy and makes you want to sing along^_
