FEBRUARY 16--Angered that a couple in a neighboring apartment was making “too much noise during sex,” a pair of gun-toting Texas sisters allegedly threatened to shoot the loud lovebirds, according to cops who arrested the siblings for felony assault. Investigators busted Alexis Davis, 25, and Treasure Bibbs, 21, following a confrontation early Monday morning at an apartment complex in Houston. Davis and Bibbs were arrested for aggravated assault with a deadly weapon, which carries a maximum penalty of 20 years in prison. Davis was busted last year for allegedly stealing a 2008 Buick from a used car lot in Pasadena, a Houston suburb. The $8000 vehicle had been repossessed after Davis failed to make any payments beyond the initial $1700 she put down on the auto.
