HUNTA-219 | When I took off the condom and inserted it raw, my sister changed completely! My sister, who is taking the entrance exam for a very difficult university, is studying hard every minute. My sister devotes all her time to studying, and she doesn't have any romantic relationships, let alone masturbating, so she always calls me, her younger brother, to relieve her pent-up sexual desire and makes me insert it with a condom.
Description
My super smart sister is devoting all her time to studying for her entrance exams to a prestigious university! She has no time for romance, and of course she doesn't masturbate, so her sexual desire just keeps building up. She calls me, her brother, to her room to satisfy her sexual desires, and releases her sexual desires and stress by having sex with a condom! But she's only studying during penetration, so she doesn't feel anything and doesn't react. I feel lonely... so I secretly take off the condom and insert it raw and cum inside her! Then, my sister, who is so excited by my raw dick, becomes obsessed with sex!
