Some of your shit is made up. Either that, or I'm missing some extremely subtle pun.
Page 38 Your TL: I'll pour lots of semen so "learn" as much as you want! JP text: たっぷり膣内射精してやるから遠慮なく孕めっ! Author intent: No idea where "learn" comes from. He's telling her he's cum a bunch inside her, so she can go ahead and get knocked up.
Page 38 Your TL: And excel! JP text: そして飛べっ! Author intent: 飛べ (or to fly) is often used as a euphemism for cumming. He's telling her to cum... not to excel?
Page 37 Your TL: I'll teach you sex as you wish! JP text: 望み通り先に孕ませてやるっ! Author intent: Another sentence where the whole impregnation aspect is omitted.
You messed up pronouns/subject in some places, like on p.5 bottom left, it sounds like Nanako talking to Natsumi, so it should be you instead of she/her, and the special note on p.39 is clearly about the girl so it should be she.
