[ENGLISH-SUBTITLE] MIDV-787 As soon as I got my girlfriend, I was allowed to insert it for only 3 seconds! The short time sex with my playhood friend

"If it's only 3 seconds, it doesn't count as cheating!" As soon as I got a girlfriend, my tsundere childhood friend Mia got jealous and suddenly came after me with a mysterious rule! "You're still a virgin, right? It would be a shame for your girlfriend if you don't practice kissing and sex!" Mia claims to be experienced, and I have to deal with her every day, so our 3-second short-time sex that doesn't count as cheating escalates more and more! At first, I really thought it was just practice, but our compatibility was better than I thought... "If we follow the rules, it won't be cheating," I told myself desperately, but I also wanted 3 seconds, sex with Mia! We counted and climaxed many times, and the two of us made love and made love to each other. ___But was 3 seconds really that long?!
