They were obsessed.
Hermione had made it clear, no strings attached and yet they couldn’t let her go.
They hatched a devilish plan, brewing a replacement preventative potion, swapping it in secret.
They made sure she was ovulating and pulled her into the bedroom.
A few weeks later she showed them a test, both boys looked just as confused as her but inwardly were thrilled.
They told her not to worry and that they would take care of her and the baby growing in her belly.
She agreed she would keep the baby for their sakes.
She was theirs forever.
