A sexy office lady who looks good in glasses came by. At first glance, she seems intelligent, but once you talk to her, you realize she's quite the lewd carnivore. It's said she always keeps a casual sex partner and indulges in her instincts. What would happen if you deliberately took your time, slowly tormenting this insatiable older sister, repeatedly stopping just short of climax, and then finally thrusting a huge cock into her... The sight of the straightforward older sister almost crying as she cums is magnificent!
