10-Minute Limit! Childhood Sweethearts Swap Bodies! HUNTC-356

I took a photo with my childhood friend using the latest face-swapping app. But after taking the photo, we both passed out. When we woke up, we felt a strange sense of incongruity. Huh? Something's wrong? My body has breasts! Eh—did we swap contents? Lifting my skirt reveals underwear… I felt the urge to pee but couldn't pee standing up… This can't be real! Then my childhood friend, who entered my body, was equally astonished… But our curiosity about the opposite sex's body couldn't be suppressed, so we explored each other's bodies, checking our genitals and penises… Then we got erections, and our vaginal fluids overflowed… Wow, amazing! We were incredibly excited. Then, 10 minutes later… Huh? We switched back! But both of our genitals were ready… What to do about this pent-up frustration? In the end, we both thought the same thing: to suppress the pain in our bodies, we decided to have sex… If we stay in this swapped state forever, it will be really bad…
