My sister Noa is crazy about me, and since she was staying over, I had planned to save myself for our first time together after a week of abstinence—but she got jealous and secretly watched me. While I thought she was away, I jerked off; during cooking, I had sex; she snuck into the bathroom to give me a handjob; in the toilet, she gave me an assjob; and while I slept, she had sex with me again... She stole every last drop of my cum.
