Richard Forsyth, 32, is on trial at Shrewsbury Crown Court having denied 18 sexual offences against seven women.
He is accused of one charge of rape, two of attempted rape, one of assault by penetration and 14 of sexual assault.
The attacks all allegedly took place in the first half of 2020.
Forsyth, of Brookfield Close in Weston Rhyn, was in the dock on Tuesday when one of the alleged victims was cross-examined.
She alleges six incidents of sexual assault and one of attempted rape.
The defendant's representative Mr Paul Smith put it to the woman that she was lying about the allegations and that Forsyth had "never" sexually assaulted her.
He also said there was a "witch hunt" against the defendant and that she "just joined in".
The woman denied these claims.
The trial continues.
