Sister caught me fucking my sex doll

I've never been a great ladies' man and instead of masturbating I bought an expensive sex doll. I've my own home and I lived alone and kept to myself mostly. My sister moved to the city to find work after her previous employer closed down. So, she would stay with me until she had a new job and found her own place. She quickly got work and while was working, I would fuck my sex doll. She and I knew her job was only short term, but not as short term as it turned out to be. She left for work as was usual for her and I got my sex doll ready to fuck. I was fucking the doll when she walked in and caught me. As it turned out, she was told on the way to work the work was finished. So, she returned home and caught me. Instead of making fun of me she asked me would I like a real woman instead. I agreed and we've been fucking ever since, she has a new job and it's a better job than before. But she isn't in any hurry to find her own place.
