My Sister took my Virginity

My sister Kathy 28 the oldest the 3 of us was bored during the lockdown for Covid. I Clarence 22 youngest was living with her and going to the local university and also bored with being lockdown. Kathy worked as receptionist and with the lockdown was stuck at her apartment with only me. I was still a virgin and didn't get many dates, Kathy dated a lot and wasn't a virgin. Anyway, I was in my room and got hard-on and had started to take care of it in the usual way by masturbating myself. I had just started when Kathy came in to ask me about playing cards with her. Caught with my cock in my hand, she just smiled and turned to leave. Then she stopped turned back and asked me did I need help. Not knowing what help she was offering, I accepted and so she took over stroking my cock. Then without saying anything she removed her top and bra, then started sucking my cock. I was in heaven and let her do whatever she wanted to do, after she had gotten me off told it was my turn to get her off. I did as she instructed and managed to do get her off. Which was when I got another hard-on and this time, she told me to fuck her. I did as I was told by her and became her Sex toy, it only ended June 2021. She had gotten another boyfriend and I was left to find a girlfriend. Which I did in late 2021, I still live with Kathy, she doesn't fuck me anymore. But she doesn't hide her body from me either. When we are alone together in the apartment, she walks about naked and walks into the bathroom and joins me in the shower.
