HUNTA-219 When I took off the condom and inserted it raw, my sister completely transformed! My sister, who is taking the entrance exam for a top-tier university, is studying so hard that she doesn’t want to waste a single second. She dedicates all her time to studying, so she doesn’t have time for romance or even masturbation. To relieve her pent-up sexual desire, she always calls me, her younger brother, and lets me put on a condom and insert it.
