Uncle's Live-in Girlfriend

after graduating from hs when i was 17 i was quickly offered to move in with my 40 y o uncle so that i can work at his company and get experience as an accountant and doing paperwork for him. it has been very rewarding and i'm thankful for what he does for me. i had to move 2 towns away from my parents for this so it was even more convenient that he was letting me stay with him. we had always been very close and he has been like the best uncle ever. since then i have grown quite experienced in the field but since it was just the 2 of us other things have grown... like our relationship. we soon fell in love with each other and it has now been almost a year since we have become a couple. the quarantine periods further allowed us to learn more about each other and bring us closer. now i am practically his wife doing the chores, laundry and cooking :) he also treats me well with massages and g*fts and other nice things every now and then. i feel indebted to him as i have achieved many things because of him. i act as his servant at home and our relationship is also quite sexual. he often asks me for a blowjob and i'm always more than happy to suck him off. he is quite big, has heavy balls, is quite tasty and has thick and tasty sperm it's no wonder i am attracted to him. he has also been training me for anal and we are getting there... even his fingers and tongue feel incredible. i can't imagine how good his dick would be in my ass. our anniversary is coming soon on the 12th of june and i think i will let him fuck my ass on that day! even if i am not even close to being ready... i think he will enjoy it a lot :)
