I have a younger sister who is reckless with money and is always in a financial pinch! That's why she comes to me, her brother, suggesting, 'I'll let you do a handjob over my pants in exchange for some money!' driven by her desire for pocket money, almost as if it's a part-time job. Honestly, I'm not interested in her at all, but it's cheaper than going to a brothel, so I accept her proposal... but maybe because I rubbed too much, she got too excited and turned into a super lewd girl who started thrusting her hips to try and insert my dick! Once she inserted it, there was no way to stop her anymore...
