Classmates run a sex experiment
Lina Sun spends the day studying with her classmate. Sitting side by side, they occasionally assist one another and other times try to snoop into one other's notebooks to see whether the answers match. Everything is silent and at ease. Lina Sun drops a pen out of nowhere. Instead of simply getting up and going around the table to fetch it, she lies down and reaches for the pen. Even if she doesn't succeed, she still gets to show her eager student her luscious pussy. They tuck their notebooks away and make better use of their limited time.
