DHLD-011 Before the test, my sister and her friends are having an all-nighter study session. Due to being too focused on studying, they let their guard down completely, resulting in pure white panty shots and the room filled with the sweet and sour scent

While my parents were out, my sister brought her friends over for an overnight study session. The sense of security at home and the focus on studying made their lower halves completely unguarded, resulting in constant panty shots!!! The incredibly cute girls' panty shots immediately got a reaction from my dick!!! I accidentally got hard, and they noticed. These girls, who are curious about sex and love mischief, deliberately flashed me to enjoy my reactions. Eventually, not knowing what to do and freezing up, they came over to me... and I was made to study various things with my dick.
