Go back?

You abashedly walk back across your lawn to Mr. Robinson's and ring the doorbell. With a towel in one hand, you explain to him that you have no hot water, would he mind you using his shower?

"Not at all," Mr. Robinson replies, "I was about to hop in myself, so I hope you don't mind sharing. I have a two-person shower after all"

"I guess not," you answer awkwardly. This is something you've fantasized about before, its not like you were going to say, "no".

He leads you to the bathroom, and you are taken aback at the sight of the luxurious bathroom. Twin sinks with beautiful granite counter tops and a walk in shower, with a soft, waterproof bench built in!

Mr. Robinson turns on the water and proceeds to pull off his silk robe, revealing his slim blue speedo, cock bulging prominently. The large outline of his cock in his speedo causes yours to jump unconsciously. He takes notice of this but makes no mention of it, he faces the shower and slowly pulls down his speedo, showing you his shaved ass and balls. Your cock jumps even more at the sight of this and you hesitate to undress.

"Come now, Sam." he says, "Lets get those clothes off."

He unabashedly steps forward and removes your clothes, quickly revealing your ridig cock, trembling now that you're so turned on. He grabs it loosely and pulls you forward, opening the shower door with one hand as he leads you in.
