My grandma

I have lived with my grandmother for almost 6 months and for the past couple of months we’ve been having sex, it started when she found me in her bedroom wanking with a pair of her knickers, she said that she had found it sexy and she wouldn’t say anything about it if I had sex with her, she hasn’t had sex since being widowed several years earlier and still had needs, we slept together that night and she wanked me off, but I did cum in her mouth, the next night we made love and I ejaculated inside her, we are having sex at least once a day and we’re sometimes having kinky sex, I’ve had her wearing a plastic raincoat and sometimes I have her wearing her quilted dressing gown, turns me on so much, and a few weeks ago I had my grandma with her hands tied and I used a pair of her knickers to gag her and then I forced my penis up her bottom and had anal sex, she now likes to be tied up and gagged during sex, I’ve now been using her bed jacket for a cum rag and I will be using it to blindfold and gag her soon.
