HUNT-931 - See-through shower curtain! The bold female friend's temptation

Living alone in the city, an old female friend from my hometown drops by and acts like she owns the place. Annoyed, I peek at her showering, only to realize the shower curtain is completely see-through! While I'm staring, fully erect, she notices my bulge and decides to show me exactly what she's been missing back home, unleashing all her pent-up desires on me.
