During spring break, you get to stay at my cousin Rinka's place!
You haven't seen Rinka in 10 years She has become really busty and athletic, and lives all by herself!
As you live together, you catch Rinka changing clothes!

She takes off her clothes.
Revealing her body underneath.
It's wrapped in a tight, neatly fitting, deep blue...

Swimsuit!?
