According to my husband I've been picking on Severus so Harry is hitting floor in this one :)
The annual charity exhibition duel and cricket match, Potter's idea of course! Started several years after the war to improve pureblood - muggle born relations, not a bad idea really, for Potter.
Severus pulled his on his whites sleeves he missed his robes, but after he had dispatched Potter in the duel, his eighth win! They'd tied twice and Potter had five wins of his own, his wife had deposited the whites in his arms and with a threat that broached no refusal, "If you desire to touch, taste or enrobe yourself within my quim again Severus Snape you will do this with all the grace I know you possess"
He sniffed, he'd done respectably in this limited overs game 54 for 5, Grubbly-Plank's or rather Grubbly-Plank-Tittensor's new husband Tittensor of Titten had knocked several 6's for his team, and although it may have been thought to be horribly un-sportsman like to not divulge to Potter the man's parentage being 1/8th troll and therefore quite a bit stronger than a wizard he didn't truthfully feel guilty in any way, he'd won with grace, his lady wife would be assured that he was on his best behaviour and if Merlin was on his side she would do that thing with her tongue tonight and ride him to completion.
Where were his children? He spotted the middle 6 easily, 2 sets of identical triplets the witch was rather fecund, 15 and 10 years of age, 3 girls, 3 boys he often wondered how he'd created these good-looking little beast, intelligence was taken for granted, but in the merger of his and Hermione's genes they had created this slew of rather attractive little snarked mouth bastards, he was quite proud even the boys with junior estimations of his beaked nose and their mothers warm eyes and curly halos were handsome, the girls all had black hair even Ceriwend who truthfully for the things that came out of that child's mouth should have looked like Luna Lovegood, if Eve his first held his heart Ceri held his soul with eyes as black as night she at 8 with her unearthly ways of seeing spirit and magic was frankly amazing, which is why when she released her Grandmother Granger slid up to him and announced
"Father, Eve. Do you think she and Albus know they will make a new soul today?" he'd pointed his wand and spat the charm for finding his children, setting off at a mad gallop praying that his beautiful daughter would not conceive for Potter's ill named brat today.
Hermione startled, Severus was running! Her husband did not run ever! She grabbed Harry's hand and started after him.
Severus was in the hallway when he heard that sound, he'd fathered more children than Arthur Weasly he knew the cry of a witch near completion, he braced himself and blasted the door off its hinges, and was treated to the pale ass of Albus Severus Potter as he performed cunnilingus on Eve while Scorpius Malfoy buggered him.
He didn't faint although as he hexed the bullocks off the pair of them he heard that solid thud, the sound of body against wooden floor and his wife exasperated cry of "fuck!"
Harry Potter saviour of the wizarding world, head auror had fainted. Hermione after forcing the children to dress and go to the sitting room, sending of a patronus to the Malfoys and stuffing a bottle of smelling salts under Potter's nose and handing him over to his wife had given Severus a wicked grin and a snarkily commented on his removal as the Wizard's Fainting Champion as they walked together trying to figure out what to do with their triumvirate of miscreants.
