The 20-year-old Harlequins' wing got three tries in each half at Allianz Park as she played for the senior side for the first time.
Jess combines playing rugby with studying for a degree in Sport and Exercise Science at the University of Chichester where she is in her second year.
She was a talented hurdler in her youth where she represented England Schools but decided to focus on rugby. After starting her rugby career at Chichester RFC, she moved to Aylesford Bulls (which became Harlequins Ladies this season) and played for England at Under 18 and Under 20 level.
