Just had an idea for a quick once-off, one scene story.
The premise is:
A lunchtime lawn party at a house. While a group of people are chatting by the lake, an over-eager family labrador runs past, knocking one of the mom's at the party (who is very busty), and her son's friend into the lake. Both go upstairs to change, but have an argument over who gets to use the shower first. The mom believes she should get it first, but the son's friend is adamant, and quickly gets naked and heads to the shower. Reluctantly, the mom has no choice, and soon she grudgingly joins the son's friend in the shower. Whether is leads to sex, or just fondling, is up to us.
PM me if you're interested!
