you only have enough sperm to guarantee pregnancy in one of them

Pregnancy is not a matter solely dependent on sperm count.
There are plenty of variables.
It's like saying you'll roll enough dice until you roll a 6. Sure, getting a 6 with a single die is unlikely. But rolling 10 million dice won't get you anywhere if the dice only go up to 4.

I can see why would you become completely impotent after that.
But why would you bother impregnating a girl, that would abort the child? Even if she doesn't the life of the newborn child would be a literal hell with all those illnesses you two will pass on him.

Whats the story behind this one?
How did she grow up so fast or is it her sister?
This is really important.

It's probably a doujin, dude.

Look at the shota, he's all grown up. It's probably set a few years after the manga

>>157193634
Not the one with the stupid pig tail scrunchies.

>>157200685
That's grown up?
I mean, you're probably right.
Heaven forbid we have a plot with actual age progression where the twin tails loli got so jealous that she did something drastic like take a bunch of hormones to trigger a massive growth spurt and rapid puberty.
Or that she pulled a Mrs. Takanashi and willed herself to grow up super fast so she could have her way with her classmate.
No, the real answer is that the classmate is all grown up, he's just a turbo-manlet.
