Can I Watch You Jerk It?

I'm stunned at my own folly, neglecting to secure my entryway, which led to an embarrassing encounter with my stepsister Alice catching me pleasuring myself. Initially fearing repercussions, I was surprised to discover Alice's laid-back stance on the situation. In fact, she expressed a keen interest in observing me engage in self-gratification with my substantial manhood, which seemed to arouse her greatly as she proposed performing oral sex on me.
Enthralled by her undeniable attractiveness and impressive bosom, I couldn't resist her advances, culminating in a passionate lovemaking session where she eagerly sought to be filled by my ample member.
