DESCRIPTION
You can find this one on twitter.
Momimomi is the onomatopoeia of grabbing breasts or any soft thing. A recent post about Hatate's catchphrase being hatata made me remember one of Hidefu Kitayan's 4komas in which Momiji tries to have her own, resulting in her saying momimomi.
There's also an alt included with different colors I found cool, but maybe that one would look better with an appropriate background to go with it.
