Prompter/Prompt: Prompt 5 from eriador117 For some reason (potions accident, curse, maybe he's part Veela or something) Harry goes into heat and it's up to Snape to keep him from committing any indiscretions--at least, keep him from committing any indiscretions with anyone else.
Summary: Severus Snape was not one for ‘dating’. It fell to him, then, to capture himself a Mate.
A/N: Wishing my Giftee a very Snarry Christmas, I hope that you enjoy this. Hugs to you! Thank you to the Mods for running this again and making us feel all festive and full of Snarry joy.
