I agree with you, this is far too little as a punishment. They should have stuck thumbtacks with adhesive tape on her wide open vulva and clitoris and at least 40-50 strikes. Then she wouldn't have been able to put her panties back on, this young slut ...........!
This is like a fictional scene where she's in a place where masturbation is a crime and she was arrested after she was caught masturbating (fingering her vagina) in the women's restroom, she needed to have her pussy automatically slapped like this as her punishment, after this: she is released/free and she's been told to not put her fingers inside her vagina again.
Arrestingly beautiful young woman with adorable pussy and anus received more strokes than I could count raising her pussy to a most attractive swollen pink with delightful "Ows". The impersonal relentless machine strokes heighten the experience for her and us. A complete delight!
