Masturbating with a big cock and teasing my sister's pussy

After a long day at work, all I crave is to unwind in the bathroom with a refreshing shower. As the warm water cascades down my body, I can't help but feel a stirring below. With a devilish grin, I reach down and start to stroke my throbbing member, watching as the water droplets roll down my big cock. The thrill of being caught only adds fuel to the fire, making me even more aroused. As I continue to pleasure myself, I can't help but notice my sister's panties on the floor. The thought of her soft skin and moist pussy sends my heart racing. I decide to take a break from my self-pleasure and explore her intimate area, teasing and touching her through her panties. The look of surprise and excitement on her face only makes me harder. This is just the beginning of our wild and naughty adventure.
