Im not a granny grappler so dont like old women , they tend to be dry down below and have sh1t breath..
Oh Id still bang it but close my eyes and think of there daughters or other younger family relations of hers.
All that matters is Bobs is happy , he now has a fatherly figure in Nasser and marrying an old lady will finish the balance , and who knows she maybe rich

Good luck to Bob,Granny and Nasser.
