If we get caught, we'll be expelled!! But we can't refuse!! Exciting sex in a school where we absolutely can't be found out, with our voices held back. Ejaculating in a situation where we can't make a sound is the ultimate pleasure! (1) A secret blowjob while preparing for an inter-school event (2) Catching a voyeur and having secret sex in the locker room (3) Secretly using toys during a meeting (4) Whispering and holding back our voices in the boys' bathroom (5) Hiding under the covers in the nurse's office for a threesome. Uto-chan can't hold back even though I told her to be quiet, and she screams out loud! Her moans are leaking out and I'm so excited!!
