You get distracted

You shook your head and couldn't help but chuckle. "You know, if you'd told me yesterday that anything like this might happen, I'd have thought you were insane. ... Actually, considering everything, we probably all are."

Monika gave a small grimace and looked away, but before you could say anything, you were distracted by Sayori managing to get her bra off. The bit of fabric fell to the floor, and everything left your mind except the fact that you were seeing your best friend's breasts.

...

"Are hers really that much more impressive than mine?"

You blushed and jerked your head up at Monika's question. "Huh?"

Sayori shy grin faded as she processed what Monika had said. Then Sayori lunged and hugged the club president. "Of course not! Your breasts are wonderful!" And having said so, she brazenly groped the other girl. "So soft... Don't you think, Player? You looked like you had gotten a pretty good feel for them."

These girls were going to be the death of you.
