Took My Dad's Maximum Strength Viagara!!

Oh boy, I made a major mistake. I was so preoccupied with preparing for my exams that I accidentally took one of my father's erection pills instead of an aspirin. Now I'm stuck with a persistent hard-on that just won't quit.
Faced with no other option, I had to confide in my stepmother Victoria about my predicament, despite the awkwardness of the situation. My stepmom did some online research and determined that the best way to alleviate the situation was for me to ejaculate to get rid of the erection. Being the supportive stepmom that she is, she initially assisted me in masturbating, but that didn't seem to do the trick.
In a bold move, she revealed her ample breasts to me and even engaged in oral sex to help me out. However, even that didn't lead to the desired outcome. Thinking quickly, my stepmom decided to strip down and straddle my erect member, riding me in an attempt to bring me to climax.
The sensation was undeniably pleasurable, prompting me to take charge and engage in intercourse from behind while fondling her generous bosom. My stepmom seemed to thoroughly enjoy the experience, expressing her pleasure with moans of delight. To my surprise, she didn't protest when I eventually ejaculated inside her cleanly shaven vagina.
I can only hope that my father remains oblivious to the events that unfolded.
