Overview： My father remarried and my new life began in the downtown area! My step-sister from his second marriage had a difficult upbringing and is extremely vulgar! She uses bad language,likes dirty jokes,and it's not uncommon for her to walk around in her underwear! She doesn't call me by my name,but just calls me "virgin-kun". It's hell! Then one day,I couldn't resist her vulgar yet attractive invitation to "want me to give you a handjob," and my step-sister gave me a handjob. Since then,I've been used as a pet for her sexual needs and made to have sex with her over and over again.
