Lauren's in the bath

Lauren lounged in the bath, sighing in contentment. On her day off she made a point of spending at least an hour in the bath. The rest of her life was so uptight and restricted, it was the perfect thing to unwind, naked and relaxed in a pool of warm water. Of course, this generally involved at least three self pleasuring sessions. Lauren was so repressed that she found herself nearly always horny. This was among the only times she found release. Speaking of, she hadn't started the real fun part of the bath yet. Raising an eyebrow mischievously her hand went to her clean shaven crotch in the water. As soon as she touched herself a shudder of pleasure ran through her...

KNOCK KNOCK KNOCK!

A loud banging came at her front door, interrupting her pleasure. Who could it be?
