Having to stay with my Grandmother

I'm Jarrod 20 single unemployed, I had a job in a music store last year. But lost it due to the Covid 19 shutdown. So I moved in with my mother's mother Frances 61 widow of 6 years. She was the only relative living near. She lived in a 2 bed apartment and I would be able to stay with her as long as I needed. After several weeks of the lockdown I was bored and horny I started to masturbate while Frances was napping in her room. While I was doing masturbating there was fender bender outside in the street. I wasn't concern and kept masturbating myself. But it had awoken Frances and she came in to see me and caught me masturbating. She asked me to let her stroke my hard-on and I just nodded okay and so she took over the stroking. One thing led to another and we ended up fucking on my bed. I'm still staying with Frances and sleep with her every night.
