The Tim Mahoney story just keeps getting worse and worse.

First it was a settlement over an alleged affair; then it was a second alleged affair; then it was admitting to multiple affairs and now it's seedy details behind the settlement with Mahoney's former mistress.

ABCNews.com reports that documents show Mahoney asked Patricia Allen, his former mistress and staffer to engage in phone sex and perform as a "tease c-ck" for big donors.

From ABCNews.com:

The settlement was reached after Allen hired a lawyer who sent the Congressman a "demand" letter, listing specific examples of Mahoney's alleged "gross misconduct" and "stalking" including:

a) Calling Allen late in the evenings and demanding "phone sex;"
b) Demanding that Allen answer his calls or face termination;
c) Demanding that Allen attend fundraisers and "tease c-ck" to bring in more donations from the male members of the public;
d) Demanding that Allen engage in sexual conduct with another woman for his enjoyment.

Current and former staffers told ABC News the allegations contained in the "demand letter" sent to Mahoney were backed up by tape recordings of phone calls between the Congressman and Allen.
