My Life's Way Of Being Happy

Three days a week I travel over to my grandfather's home and fuck him.
He's unable to get an erection these days, so it's extremely difficult for him to ejaculate.
That's where I come in, literally.
After he's sucked my seven inch dick hard, I'll fuck him in whatever position he wants, and after a few short minutes he'll cum from having my cock rub on his prostate.
Lots of times I won't even cum myself, but save it for my true lover.
And he also is a family member. Indeed it was my grandfather catching us fucking, which gave him the idea to have me 'service his needs' as he put it.
I live with my lover, a wonderful man who saved me from a physically abusive step parent.
He's my uncle and we have sex daily. With him I'm predominantly the bottom and love having him fuck me, which he does twice most days. Either my mouth or arsehole, or both.
I know I'll probably get bad messages, but trust me it's a very loving family I Now have, and I wouldn't swap my situation with anyone.
Plus we're hurting no one.
