My younger sister Noa likes me way too much. I thought I could finally have my first sexual experience after a week of abstaining from masturbation when she came to stay with us, but my jealous sister secretly stole my semen while Noa wasn't looking and used it! She even gave me a handjob when Noa wasn't looking, had sex with me while Noa was cooking, snuck into the bath to give me a handjob, anally pleasured me in the toilet, and even had sex with me next to Noa while she was sleeping... In the end, it felt so good that I completely ejaculated all my semen...
