My sister loves me so much that she'll do anything to make me happy. Lately, she's escalated from hand jobs to blowjobs! And she does it in front of our parents with her blowjob technique, making me sweat bullets! Ignoring my feelings, my sister whispers, 'Don't you want to do something even dirtier?' With a mischievous smile, she says, 'I've already put it in,' crossing the forbidden line in an emergency situation! Even if I say no, it's too late... I've already cum...
