Need help finding a story

[Kim_in_VA]

Can someone help me find a story? Here is the gist -

An older man helps a neighbor (possibly a widow) with household repairs. She repays him by introducing him to sexual techniques and devices. He is tied to the bedposts and slowly teased to orgasm over and over by his new friend. Once he reaches orgasm, she continues with the teasing to push him limits.

Thanks for the help!
