We wanted to test the sensitivity of a competitive swimmer's nipples! So we snuck into the pool at a women's physical education university. We handcuffed Sakura-san, whose face and body are incredibly attractive, and subjected her nipples to various stimuli, recording her reactions. Sucking and licking her beautiful nipples made her say, "I can't breathe, it's so embarrassing..." While panting seductively, she wiggled her legs. Then, we did a powerful vibrator sandwich on her nipples! With a special suction rotor, her waist felt like it was being pulled out, so she did an acrobatic cunnilingus and accidentally inserted a dick! While sucking her nipples and cumming profusely (at her request), she moaned uncontrollably and squirted. Her nipples were so sensitive that the pool was about to overflow!
