While I was in bed with a cold, my JK little sister saw that I looked lonely and came to lie down next to me. Her scent made me involuntarily hard! As I was secretly jerking off, she noticed and said, 'Are you built up? Let me help you release it' and gave me a handjob and blowjob, but I just couldn't cum. Impatient, my sister said, 'I can't let you insert it, but if it's just cross-dressing, that's fine!'
