A virgin student who doesn't know where the vagina is, the teacher sympathizes and practices guidance... or so it was supposed to be... Hey teacher... is this the vaginal hole? Just line up the tip, okay? You must not insert it at all... Whoa! Don't really move! Stay still! Shaking... quivering... plop! Noooo! The teacher's place is slippery and it slipped in! But somehow it feels good! I can't stop my hips! The virgin dick goes on a rampage from the pleasure of the vagina! Unstoppable vigorous pistoning! What are you doing, moving your hips on your own! On top of that, it explodes with a huge amount of internal ejaculation! Huh? Could it be that the teacher is feeling it?
