I was so excited to see how cute my nieces were in their uniforms when they came to visit my parents' house...They had their legs exposed and it was cold, so they immediately came under the kotatsu, so when I looked inside, I could see their cotton shorts. - It was panty shot heaven! - Perhaps because my guard is relaxed inside the kotatsu, I get an erection from the spectacular view where I can clearly see my pussy muscles. - Then, I found out that I was peeking and found out that my erection was there, and I was in a big pinch...! - My niece is so curious that she touches his erect penis and even begs for sex!
