You know what I like? Certain doujin tropes. Here's one of my favorites:
Big tiddied, tough looking tomboy, who's actually a real sub, confesses her love for her much smaller senpai, only to find out that -
A) He has those same feelings for her, and
B) He's hung like a horse
Certain cute interactions later, they get busy.
So here's a scene and a character I made just for that trope alone.
Enjoy ;)
