My Friend's Sister Is Not Nice To Otaku, But She Is Very Nice To My Dick!

When I went to play at my otaku friend's place, I ended up sharing a room with his gal older sister who is totally not nice to otaku!! The moment she saw me, she flipped out saying 'Don't go adding more creepy guys without permission!' But when my friend was gone, she made a devil's deal: 'Lend me money, I'll give you a handjob in return.' Scary... but erotic! I got both my money and my sperm drained. As expected, she threatened me every day with 'I'll milk you again, so lend me cash.' But it turned out she was actually addicted to my dick, and one day she couldn't take it anymore, saying 'Don't you dare look at me...' as she straddled me for raw insertion and a raw creampie! From that day on, my life became one of non-stop fucking with a gal older sister who is strict with otaku in front of my friend, but clings to my dick and demands creampies when we're alone!!
