HUNTB-015 "Brother's sperm is exciting!" In my room where I'm not popular, is my teenage stepsister a fellatio junkie? The new stepsister from my parents' remarriage is innocent and cute, but...

My stepsister, who came into my life due to my parents' remarriage, is innocent and cute, but our relationship is still a bit awkward. Trying to get closer, I invited her to my room, and she said, 'This room gives me some strange feelings...' and started squirming? My stepsister, who gets aroused in my room where I only masturbate, suddenly goes wild and forcefully sucks on my dick! Unable to hold back any longer as my stepsister becomes engrossed in giving head, I cum. She's incredibly excited, with semen dripping from her mouth as she starts thrusting herself onto me.
