The urge to partake in autoerotic activities overtook Kim, and the idea of her controlling her boyfriend’s penis to this extent for the whole day gave her a lustful drive she hadn’t felt in quite some time.
Not wanting to press her luck and masturbate over the panties, in case Dan felt his “self” enter into her vagina that way and chastise her for it, Kim gently stretched the front of the panties outward. She listened for any signs of Dan being able to feel her stretching his ex-penis out, and heard nothing. He still hadn’t left for work yet, but she couldn’t wait much longer. Her primitive instincts overpowered her, and she slid her hand on top of her vulva. Within seconds, she was fingering away at herself.
After about two minutes of pleasurable moaning and drooling (which Dan somehow managed to hear none of), Kim finally ‘arrived’, squirting all over the panties. The sensation of this earned a quick “huh?” from Dan downstairs, but little else if anything.
Kim sighed, tired and content with herself, removing the panties from her waist slowly and carefully. As she observed them, she saw they were heavily stained with her ejaculatory fluids, and were decidedly unfit to wear in such a condition. However, Kim wanted to wear them more, and there was only one way to fix them.
After Dan left for work (with one last “take care of them” directed towards Kim), she hurried downstairs and dropped the panties into the washing machine. Pressing a series of buttons as Dan pulled out of the driveway and made his way to work, Kim started the wash.
