Ambush a serious-looking Rikejo during her break! Target science girls on the street! You'd think she'd refuse because she seems so serious, but she's totally into it and starts researching dicks! She measures shape, hardness, and angle with her pussy! Seeing a big-sized cock for the first time gets the Rikejo super excited!!! She sucks and fucks it, conducting thorough research!!! When we take off the lab coat of the research staff member, out pops an unexpected G-cup giant rack! Tits that can squeeze in an unexpectedly huge dick are amazing! The pleasure from a big cock inserted for the first time doesn't stop at the deepest part of her pussy! Feeling a big cock raw takes her to the other side of orgasm! After all, there's no substitute for practical experience when it comes to sex!
