An obstacle race where you compete against time while being hindered by tentacles is a traditional event held every year at Shin-Nakano National College of Technology. There are a total of five obstacles (tentacle bread eating/tentacle quick draw/tentacle chair/tentacle reading/tentacle pool). The rules are: if you make a sound → +1 second, if you squirt → +2 seconds, if a tentacle is inserted into your pussy or if you say the word "I'm coming" → +3 seconds, if you keep coming for 30 seconds → +10 seconds. Every time you react to the tentacles, a penalty is added to your goal time, but... tentacles crawling all over your body! Numerous tentacles that suck you in! Ferocious tentacles! Tentacles that attack all the way to the back of your throat! Who will be the winner... Number one!
