A door-to-door salesman visited the home of a virgin guy living alone.
“Want to buy a high school girl?”
Is this some shady company rumored to rip people off?
He thought...
“With our secret virgin discount, it's 2000 yen for one round with a condom!”
Wh... What?! That's cheap!?
The virgin fell for the sweet talk - hook, line and sinker, bought a high school girl and lost his virginity!
Not only did he get to cum inside raw but he also got hooked on all the enticing perverted options...
