LazyUS3R, has dared Natsuki to kiss Sayori in front of Yuri.

Natsuki: Oh well, here we go. *She say that Sayori was talking to Yuri, so she lightly tapped her shoulder* Hey, Sayori, could you turn around?

Yuri: *She blushed when she saw Natsuki and began to play with her hair*

Sayori: Huh? Oh, sure, Nat! *She turned around and smiled brightly*

Yuri: *She stopped playing with her hair and somewhat glared at Sayori. She didn't know why, but she didn't like it when Sayori called her 'Nat', even though she knew it was a common nickname*

Natsuki's mind: *You can do this Nat, it's only a simple kiss, nothing big. Buy in front of Yuri? Oh well.*

*Eventually, Natsuki grabbed Sayori's shoulders and pulled her into a kiss*

Yuri: *Her jaw dropped as she watched in pure silence, that was the last thing she expected her to do*

Sayori: *She giggled and kissed her back, not knowing that she wasn't technically supposed to do that*

Yuri: *She growled slightly as she looked away, crossing her arms. She was jealous, and I mean J-E-A-L-O-U-S, JEALOUS!!!*

Natsuki: *She eventually pulled away for air*

Sayori: Thanks for this kiss! *She chirped and skipped off somewhere*

Natsuki: No problem, Sayo.

Yuri: *Her eye twitched like crazy as she stared down Sayori* ...
