This manga is painfully bad. It's not like good bad smut, just bad bad smut.
It's like shitty sex. They skipped the foreplay, so the dick ain't hard and pussy ain't wet. Then instead of trying to stimulate each other, they went ahead stuck the flaccid thing into the dry cavern. Now they just continue slamming with sad SLAP. SLAP. SLAP. sounds hoping it tickles some people just because hey, at least the art is decent.
