ギュってして (gyutte shite) means something like "hug/squeeze me". Sometimes in gravure videos you'll see the performer squeeze her boobs together and say "gyuuu!" - that's why. Unless they are really big boobs, and then it might be a pun about milk...
Anyway, if I were going to translate this title it would be "Hug me! Koharu Nishino Part 2".
