MIDV-787 Once she's ready, you only need to insert for 3 seconds! The brief sex with my seductive childhood friend was so perfect that I ejaculated again and again... Nanazawa Mia

"Cheating doesn't count if it only lasts three seconds!" My childhood sweetheart Mia, who's always been jealous of me since I got a girlfriend, suddenly presented me with a mysterious rule! "She's a virgin, right? If we don't practice kissing and sex, she'll be letting me down!" Mia, who claims to be experienced, is with me every day, and these three seconds don't mean cheating—the sexual act will quickly escalate! At first, I really thought it was just practice, but our compatibility was better than I imagined… "If you follow the rules, you won't cheat." I desperately told myself, wanting Mia to have sex with me for three seconds… and it happened! We counted and climaxed repeatedly, our bodies deeply intertwined. ___But three seconds is so long!?
