Hey. I posted here once before, but I'll do it again. I'd like to introduce you all to a character of mine named Millie (and her boyfriend, Mike). Here's a big picture that explains them; sorry for the wall of text.
TL;DR I guess:
Mike's a dorky but good-natured 16 year old boy who lives out in the country with a mostly absent mom. Millie is a cowgirl who followed him home when he was walking home from school. They basically live together due to having lots of privacy.
They sometimes go on dates but Mike is teaching her how to act in public, because she acts like a cow and says moo and likes to be naked. He dressed her up in the cute purple sweater. Despite her ways, don't be fooled, Millie has a healthy and mature sexuality.
How big she is depends on how much milk she has stored. Ranges from DD to massive. She has to be milked to get her excess milk out. Her tits are also sensitive and lactate easily, such as when brushing against clothes, so she lactates a lot in her sweater.
She likes doing it, though, and offers Mike her milk a lot, sexually or otherwise, from the source or in glass. She's also skilled with her tits in other ways. She also has a nice butt and she likes rough sex, anal, etc. They have a pretty kinky sex life despite the cuteness.
Millie's also super affectionate and likes attention and grinds up on Mike when she's horny but also she knows when to give him space. They have an open relationship but Mike is afraid of upsetting her by fooling around with others. Meanwhile Millie likes to play with people who are nice to her but still loves Mike more than anything.
