Is it just me or were the scenes a little underwhelming?

Well I love love loveeeee this story from deep within my body where the sun don't shine, but after all the waiting I feel like the scenes lacked emotions. It all felt very rushed. Like he just puts in in and they climax like whatt?? I know I'm not paying for artist nims work so I shouldn't complain but still. The uke didn't show much expression. I felt like on the contrary the top showed better expression. The previous chapter had me giggling. This chapter too but more like a half assed giggle.
