Even I wouldn't mind if Saki smothered me with her chest and butt. Obviously, she's hiding more...intense feelings for Jun, but I kinda like she's not afraid to both act up and be a little sexy in public.
I'd straight-up kiss Saki after sharing a bit of my ice cream. And soon after intrusive thoughts of wanting to be inside her despite her being my stepmother start popping up.
Thank you for the translation (sometimes it's nice to just...release all your love, frustration, and sadness building up in your crotch inside an attractive older woman praying upon you).
