Female students are very shy. When they realize that boys are looking at their underwear, the first thing they will do is try to close their legs. The boys, who are too focused on the underwear in front of them, will be trapped between the girls' thighs, unable to move and will be writhing in agony... What?! They're actually happy to be sandwiched between the healthy, plump thighs of the girls and get to see their panties...!? I see, that's why the boys' dicks are rock hard. Oh, the girls have noticed your erect penis!?
