Taking photos with a childhood friend using a recently popular face-swapping app. However, immediately after the shoot, the two of them lose consciousness. And the strange feeling they felt when they woke up. Huh? Something's wrong? Breasts on my body! Eh- does this mean our insides have switched? When I lift her skirt, there are panties... When I feel the urge to pee and go to the toilet, I can't pee standing up... No way! And the childhood friend girl who entered my body is also equally shocked... However, their curiosity about each other's bodies cannot be suppressed, and they grope each other's bodies and check their pussies and dicks... Then an erection, overflowing semen... Wow, something amazing! We were inwardly excited. And 10 minutes later... Huh? We're back to normal! But our crotches are in a ready-to-go state... What should we do with these unplaceable, agonizing feelings? Then, what they were both thinking was the same, and they decided to have sex with one heart to suppress the throbbing of their bodies... If we had stayed switched forever, it would have been really bad...
