My first girlfriend. Both she and I are new to love and we don't know what to do when it comes to sex! So I asked my sister-in-law for advice, but she's a slut! My sister-in-law has been practicing sex with my girlfriend...? But my sister-in-law's common sense is way off the beaten path! She's become a dirty pervert! It's not normal to have deep throat, squirting, threesomes, lesbian sex, or raw creampies for the first time, right?! The long-awaited first sex turns messy!
