Play with herself.

 Crystal pulls down her bikini bottom and sits her now burning ass onto the cold toilet seat.   She lets out a sigh of relief as her well spanked ass enjoys the coolness of the seat.   Though this only made her pussy feel hotter and wetter.  

 She slips one hand under her bikini top and begins to feel her breast and pinch her nipple.   Her other hand slides down her stomach and over her pubic mound.  Her middle finger dips into her nether regions and lightly plays with her clit.   All the while her little and ring finger slide into her pussy.   Her eyes roll up into her head and she begins twich from a mini orgasim.

  She lets her middle finger slip down and play with her outer pussy lips along with her index finger.   Crystal's thumb moves over and begins to rub and pet her clit which is now poking out a bit from its sheth.  She has never been so horny before in her life let alone made to cum just from a spanking.

 Suddenly she is aware that in her hurry to relieve her sexual desires she had not bothered to close the door to her stall.  As her eyes roll down from her head and being to focus she sees someone standing in the doorway looking at her in disbelief.   Crystal also feels her tatoo being to move like it did the first time she saw it.   She feels it going to her pubic mound.   The sensation turns her on and she cumms right there in front of the person in the doorway.
