[IDed]白黒つけてよっ! + 姫さまといっしょ

you´ve got difficult questions, but I think I can solve it...

#1 + 2 is shirokuro tsuke te yo 白黒つけてよっ! / [家庭菜園] 白黒つけてよっ! -桃色動画館-

#3 is hime sama to issho 姫さまといっしょ / [家庭菜園] 姫さまといっしょ。 -桃色動画館-

both of them are DLsite material though. But you know the names now...
 
1 and 2 are from 白黒つけてよっ. 3 is from 姫さまといっしょ . both are animated doujin games and DLsite material.

lol late by a few secs
 
nobody can know everything, at least not on 1st hit, it´s the amount of experts getting a result mostly when not always...
