While our parents were out, my younger sister invited her friends over for an overnight study session. The comfort of being at home and their focus on studying left them completely unguarded, their underwear clearly visible! Seeing these cute female college students with their underwear showing, my penis immediately became erect! I couldn't resist getting an erection. When they noticed, these sexually curious and mischievous girls deliberately showed their underwear to tease me, enjoying my reaction. Finally, unsure what to do, they came to me, and I ended up getting a good lesson from them using my penis.
