One, chilly, February morning, Snape plonked down a small cardboard box, on the breakfast table before he tucked into his eggs. Harry and Draco waited for an explanation but Snape seemed content to leave it at that.
"Are you going to tell us or wait for us to ask?"
Snape sighed as if he really didn't want to be asked.
"As I am sure you both know, there comes a time, when young adults, such as yourselves, feel the need for, intimacy, with other people"
Draco nodded in confusion until he glanced at Harry who had chosen to inhale his bacon at that point. "Crap, Harry" Draco rushed around to whack his boyfriend on the back.
"What?" Harry coughed out, when he could breathe again.
"Intimate relations Harry, you must be aware" Harry's skin turned an alarming beetroot colour, "what's this got to do with that box?" Draco asked.
"I may have just turned 36 Draco, which in your eye's is probably ancient, but I am still fully aware of what young men are likely to get up to and the need they will have for these, muggle devices" with that, Snape returned to his breakfast.
"Condoms?" Harry squeaked "precisely" Snape acknowledged.
"Wait, holdup, what are they?" Draco asked, never having heard that weird word before
Harry spluttered and searched for words "well you see Draco, you put it on your erm…. Thing, and it like stops the…. You know getting a girl pregnant"
Snape rolled his eyes "Coherent as ever, Potter"
Draco turned to him, "why on earth have you given them to us, we're not exactly planning on knocking anybody up?" Snape leveled them a withering glare,
"this morning, I believe it is time to have a short interlude from defensive study"
"YES!" both boys enthused, but that got them a warning brow raise.
"Instead we shall be learning about the birds and the bees" Snape couldn't help smirking at the boy's horrified faces.
After a morning that had left all three of them red in the face, Snape handed over the book he had bought. He'd purchased some muggle literature to advice himself about gay relationships, a lot was irrelevant to wizards, but it was still informative enough for Snape to lecture his charges about. Harry seemed reluctant to take it, but Draco near, snatched it out of his hands "ooh cool" he said rifling through.
Draco made no show of hiding when he was reading the book, he spent their study breaks, evenings and most mealtimes, unashamedly gazing intently at its pages.
On the day Draco turned 16, they spent the afternoon with their friends, messing around in the park, despite the chilly weather. Then Harry made Draco his new favourite, lasagne, for dinner and afterwards they had cake, Snape even spoke the words to Happy Birthday while Harry sang. Draco had insisted he wanted to help make the cake. So, the day before, despite Harry wanting it to be a surprise, they spent the afternoon baking. The final result was edible if a tad over decorated, when Draco got carried away with the icing.
That evening Harry waited nervously on the bed for Draco to finish his shower. He'd already bought Draco a few presents but he wanted to make the day extra special for him.
Draco arrived back, loosely draped in his bathrobe. Harry scooted to the edge of the bed to pull Draco towards him.
"Eager?" Draco smirked
He lent down to kiss Harry, giving Harry the prefect opportunity to reach forward and undo the tie on Draco's bath robe.
They'd never been fully naked together before and Draco was ecstatic about the development, he pushed Harry backwards, pulling and tugging at Harry's own pyjamas.
Body against body, skin against skin, the boys rolled around, reveling in the sensations and thoroughly enjoying themselves. Draco thought he'd never been given a better present, which was impressive, seen as, for his 10th Birthday his father had bought him a flying pony.
The boy's slept that night in a tangled and sweaty mess but neither bothered to move from the warm cocoon they'd made for themselves.
A/N: This story is also being posted on AO3, under the same username. The plot's nearly exactly the same but with more adult themes and language, I don't like putting stuff like that on here, with there being no age restriction. But if explicit is your thing, feel free to read it over there instead.
