My Grandma's Gambling Habit updated

Last year my grandma Heather lost gambling on a horse and needed a loan. I loaned her the money and she came over later with a cake as a thankyou and caught me masturbating. That's how we started having regular sex together, when her was raised she moved in with me. Sex is a regular thing between us still and she has gotten her friend Briony 61 widow to fuck me also. Briony is a quiet reserved woman who rarely go anywhere, especially by herself and so Heather decided she needed regular fucking. Briony only has one child Carol 26, the only reason Briony got married. Her husband Thomas had seduced her and she got pregnant and so he married her. They were fairly happy together over the years they were married, Thomas was 17 years older than Briony. But he left her fairly well off, after I started fucking Briony regular. Heather got her to move in with us and when Carol came home from university. Heather got the shy Carol into my bed as well and Carol got pregnant and so we married shortly after it was confirmed. Which was part of Heather's plan all along. My parents Rachel and Henry were surprised by our quickly marrying, but are happy to becoming grandparents again.
