My sister, who never gives up on anything, is going to improve herself as a woman for the man she loves! She has resolved to do so! She is trying to abstain from alcohol, sex and dieting! One day, I thought she was trying hard, which was unusual for her. I came across my sister secretly rummaging through the fridge late at night! The restrictions have caused her to become so stressed that she is at her limit, and not only her appetite but also her sexual desire is out of control! She took off my pants and gave me a blowjob! She didn't seem to hear my voice trying to stop her, so we ended up having sex!
