Cow Girl/Lust Grimm

Cow Girl (牛娘 Ushi musume) is an enemy and the subject of a sidequest in Lust Grimm.

Profile
''A succubus with the traits of a cow. She has a gentle disposition and is broad-minded. Her milk is addictive, the more you drink, the more you will be lost in thoughts of her milk.''

Skills
Cow Girl Press: Chest element

Cow Girl Handjob: Hand element

Cow Girl Titfuck: Chest element

Cow Girl Feeding: Chest element, hits 3 times (12 times if Magrut has Breast Addiction status), moderate probability of inflicting Breast Addiction status

Feeding Counter: used in response to Nipple Suck, high damage and can inflict Sensitivity status

Sweet Milk: Finisher, used when Lust high, inflicts Breast Addiction

Strategy
As you might expect, the Cow Girl has a lot of Chest element attacks. Using Endure:Breast may help to reduce the damage, and cure Breast Addiction immediately if it's inflicted. The Cow Girl's main weapon is also her weakness, as she takes extra damage from Chest element attacks. Do not, under any circumstances, use Nipple Suck on her; she will respond with Feeding Counter, which can kill you even if you're massively overlevelled. This applies to other enemies with breastfeeding attacks as well. She may use one or more normal attacks before Feeding Counter.

Cow Girl sidequest
A non-enemy Cow Girl appears in three locations throughout the world. Talking to her letting her breastfeed Magrut. If you choose to do so, there is a brief cutscene, after which your Lust rises significantly (potentially to over 100%), your Stamina is fully restored and the Cow Girl moves on to the next location. Experiencing all three breastfeeding events is a condition for another event that takes place in Succubus School (the other being the Succubus Dancer sidequest). If you fulfill both conditions, and have reached the Normal End, a succubus will appear in Outset House leaving you the message that you should visit the school and then examine a bed in the school infirmary. Doing so causes Magrut to go to sleep and then be raped by the Cow Girl along with the Succubus Dancer and Succubus Nurse.

The first one is in Welcome Road North (near Welcome Casino).
