Add a little sex scene or keep it as is? (Pixiv Fanbox)

Howdy folks, just curious on your opinion here.

Should I add a little sex scene after their kiss ends, or should I leave this one as is?

This one isn't going to be a super long project either way, just a fun little random bonus, but I figure I'll ask you guys if you want to see them share a dildo post kiss or cap it off here.
