I couldn't resist my niece's defenseless sleeping figure and started playing a prank on her, but she woke up and found out! I didn't want her to tell anyone, so I started managing my ejaculation with handjobs and blowjobs! My niece also secretly enjoyed stopping my dick from climaxing in front of my sister! But I couldn't say anything. Because she knew my weakness. But I couldn't stand the climax hell and ejaculated a lot! Then my niece got excited by my erect dick that wouldn't go away even after I ejaculated, and instead of telling me, she asked for creampie sex!
