Literally every To Love Ru girl they're all perfect in their own ways

The one that has big tiddies and/or booty c:

1. Annie Hughes
2. Helen Parr

Only others I regularly used to fap to are Jessica Rabbit and Lola Bunny. Other than that, yeah, just whichever character strikes my fancy, especially if they are well-drawn. So it has more to do with the artist than the character. The above two two, however, are usually safe bets for me to get off on.

1. Sailor moon (Sailor Saturn/Sailor Jupiter)
2. Nintendo characters (Palutena/Princess Daisy)
3. Pokemon (Dawn/Lillie)
4. Disney (Violet Parr/Alice in Wonderland)
5. Adult cartoons (Hayley Smith/Lois Griffin)
6. Kids cartoons (Starfire/Gwen Tennyson)
7. Overwatch (D.va/Mei)

What does everyone think of this list ;)

I have to agree with D.Va and Mei. ^^
If I had to have a list, I'd say:
Rayne, from the BloodRayne game franchise.
Quiet, from Metal Gear Solid V: The Phantom Pain.
Tracer, Mei, Mercy, Symmetra, D.Va and Widowmaker, from Overwatch.
Nea Karlson, Dead by Daylight.
Esmeralda Torres and Yukiko Hoffman, from The Evil Within 2.
Lara Croft, classic Tomb Raider and reboot.
List is kind of too long, lol.
