[NSFW] Thomas Edison is busy inventing in his basement, when his wife, Mary, goes to a friend's house to ask for her advice.

"Thomas just won't go down on me", Mary tells her friend.

"I'll let you in on a little secret", the friend replies, "If you want oral sex with Thomas, try coating your privates with something sweet tasting, it works for me!"

When Mary arrives home she checks in the cupboards and finds a big bag of sugar. She takes it upstairs, whips off her clothes and sprinkles a little sugar over her private parts.

She really wants Thomas to go for it, so thinking, "what the hell", she crams a load into her vagina as well!

That night, for the first time since they were married, Thomas finally let loose and gave Mary the incredible oral session she was after.

It just goes to show, a poon full of sugar helps Tom Edison go down.
