Exclusive: Why don't we have sex after everyone falls asleep? (Hina 300MIUM-1379)

In a back alley near the southeast exit of Shinjuku, my friend went to karaoke with a group of girls he'd been approached by! At first, I thought it was impossible, but they actually followed me... It's amazing to successfully pick them up in this day and age! The girls seemed to have been to several karaoke places already, having a great time and starting to take their clothes off. And both of them had huge breasts—what a stroke of luck! This karaoke session was definitely going to be a full-on affair, right? Absolutely no problem! Who bought this vibrator? Did they secretly buy it from a convenience store beforehand? After eating and drinking, while I was in the restroom, "Excuse me~" Hinako walked in with a grin. Huh?? I was standing there, genuinely stunned, when suddenly she kissed me—it was so unexpected!
