Living with Grandma

Long story short, I'm Daniel 20 going to university in second year. Due to being unable to find work to help support myself, I moved in with my father's mother Karen 61 (widow). I receive money from my parents to help me get by, but it's not enough to pay rent and eat. But I'm happy to stay with Karen and she is a good looking mature woman. A month after arriving I was have a shower and Karen walked in on me and caught me masturbating. She said sorry and left, I finished showering and went to say sorry to her. But she said it didn't bother her and again that she was sorry for walking in on me. Karen lives in a 2 bed 1 bath cottage and spends her days gardening and cooking cakes for social groups and church raffles and such things. A week later I came home early from the university. No more lectures that day, it was Friday and I was thinking of going swimming. On entering the house I heard moaning coming from Karen's room, I went to see if she was okay. On entering I caught her masturbating, she was laying on her bed naked with her legs spread. She was shocked at first, but soon recovered and noticing that I had got an erection. She said It seems you like the look of your granny masturbating, how about you show me your hard cock. I dropped my pants and it poked straight out at her. She was sitting on the edge of the bed at this time and reach out and touched it. Then she started to stroke it and after a bit of stroking she took into her mouth and gave a blowjob. After I had cum, she asked If I would return the favor and go down her. Which I did, after that I mounted her and fucked her hard. Later that day, she asked me if I would like to sleep with her that. I said Yes and I spent the night with her. Sex with her is now a regular event, she has also got me to fuck her best friend Ruth 67. Ruth is divorced and is lonely and very horny, she told me. Karen and Ruth are very willing to have sex anytime. But only with someone they trust, they both decided to help me with my expenses. As my parents were having cut back on the money they gave me. This is so I don't have to get a job to make ends meet and will have more time to be with them. I still go out with girls and even if I get lucky with my date and fuck her. I will still be able to fuck Karen, when I get home and Ruth is always over in the morning. Hoping to get a fuck before I go to university, It's not hurting anyone and I think I could get lucky with one my lecturers Elizabeth she 63 and looks great. I have asked Karen to invite Elizabeth to dinner and I wll see how it goes.
