After my father remarried, the stepsisters that came out were super vulgar due to their upbringing! Their language is terrible, they love dirty jokes, and walking around in their underwear is a given! They don't call me by name but 'Virgin-kun'. It's already hell! Then one day, I couldn't resist their vulgar yet charming offer of 'Should I jerk you off?' and ended up getting a handjob from my stepsister. Ever since then, I've been used like a pet for her sexual release, forced into sex non-stop. Even threesomes are no big deal to them; it's shockingly vulgar.
