You were drinking coffee, Leo was reading a book, Raph was on his phone and Donnie and Mikey were chatting

Mikey: “Hey D, did you hear those noises coming from Valeria’s room last night?“

You nearly choked on your coffee as Raph paused playing his game on his phone, the both of you having blush covering you and Raphs’s faces as Donnie answered Donnie: “I did indeed brother”

Donnie and Leo clearly knew what they did but Mikey was too innocent to understand.
