Horny twink pounds his old grandpa raw and rough

My step grand father has a very big ass and his hole is so tight that every time I think about him, my dick gets very hard. One day, as my grandpa came out of shower, I took him to the bed and pinned him down.
Then, I grabbed my dick and shoved it deep inside his ass and stated fucking him raw. My grandpa also enjoyed getting fucked mye as h moaned in pleasure the entire time we fucked.
