When my sister brought her friends over to our house, it was a cold day, so we all gathered around the kotatsu and did our homework. - So I suddenly took a peek inside. - Then, inside the kotatsu, you can watch as many panty shots of your sister's friends up close as you want! It's a super sweet panty shot heaven! - When I was pretending to be asleep and getting excited about watching panty shots, my erection was discovered! - Just when I thought it was dangerous, my sister's friend seemed to be in heat due to his erection, so he secretly touched his erect dick so that his sister wouldn't find out. - Moreover, he says, "Please touch me too"...
