I met a 70 something year old guy on Grindr a few months ago. We sucked each other I fingered his ass and he shot his load all over me. After that we had coffee and he showed me pics of him and his mates in the Vietnam War.

Pic unrelated, not him, a guy from reddit whose account is now deleted. r/OldGuysRule and similar subreddits is the perfect place for genuine daddy/grandpa fap material.
