I was playing a prank on my defenseless sleeping sister, a schoolgirl, when she woke up and suddenly started deep kissing me! Then she started sucking my dick! Ignoring my confusion, my sister's actions escalated! Finally, she inserted it raw! She started to move her hips and I was on the verge of ejaculation! It's not good to cum inside her, so I tried to move away, but she locked me in a crab-like grip with her legs, so I couldn't get out!
