My wife always use oil to my cock in foreplay. She let it rinse over the cock and massage it hard, its a nice feeling to see and feel it grow in her hands. Yesterday she hold the cock in her hand and said: ”We should make a casting of it”
Me; Why?
Wife: Look at it. Its so long and big
Me: What for?
Wife: To sell
Me: To the sex shops?
Wife: Yes

I find it really erotic - I just wanted to write it down.
