During a trip to the mall, Ririka happens to take a liking to you. She's only got one thing on her mind, and she's set on getting her way, one way or another.
MalePov because Ririka loves and I'm too lazy to figure out how to make FutaPov work. You might be able to brute force it, I dunno.

I dunno why I always had this headcanon that Ririka is a D1 , but here you go.
