Several of the A/B/O fanfics I read in the past had the omega being infertile so...I want it the other way this time XD Plus...it's a quite good excuse for a threesome. ( ͡° ͜ʖ ͡°)
4.
Setting: ...Omegaverse again ¯\_(ツ)_/¯
Pairing: Todo/Deku, then Todo/Deku/? (either TodoDekuBaku or some rare threesome pairing)
Izuku has already spent 4 of his heats with Todoroki and it's been two heats since they decided to try having a child. But even though Izuku is really fertile he still wasn't pregnant. Todoroki started worrying and decided to visit the doctor with Izuku. Turns out that the one at fault is Todoroki who, even though is an alpha, can't have children.
But Todoroki knows that Izuku really wants to have several children so he decides to do something that he should have done long ago. He knows that Izuku truly loves him. But he knows that there is another person close to Izuku's heart, so he seeks out the person (even though the aplha inside him is against it at first) to make a deal with him.
