Cas moans just a tiny bit and melts into Ren
Cas: Mh~
He moans when Ren bites his lip
Cas: Oh fuck-
Cas: Ren...
He wraps Ren's thighs around him, kissing him roughly
Cas: I like you...a lot...
He kisses Ren's neck
Cas: Heh~B-but...but I...if you like Katsuki...I-I don't...I don't wanna get in the way of that...
(Bai)
