NGL, you're not wrong that sex feels good, but that's more to ensure that humans continue to make babies. If sex was truely awkward, nothing but painful, and an all round hassle, humans would have gone extinct long ago.
The fact sex is pleasurable is both trap and reward.
I take it back @KeremDgGG, drop this shit into hell. Seggs finished first though.
Like fuck me, why not have this addressed without the set dressing of a creeper watching through the window. What an absolutely horrific and unnecessary detail. Surely the slightest bit of delicacy could've been applied to their obviously inevitable sex scene if you're going to make her a turbo virgin. Please, urgh.
This manga gone bad with this ark, but this chapters just put this on the new low. IO is basically a turbo virgin - doesn't even know what sex is, or importance of first experiences, while MC explain it like its fucking eating candy in an embarrassed way, tells her nothing of the important bits and then straight up jumps her and fucks her like a horny brain-less monkey.
