Hermione had expected that, given that this was Harry's first time ... but what she hadn't expected was for him to roar like a lion when he climaxed, or that his sudden increase in size with every long spurt would send her so far over the pleasure precipice that the final remaining power crystals in the room shattered, the runes burnt out on the walls in fiery, hissing sizzles, and the bed cracked into three separate pieces, as Harry and Hermione simultaneously came, like a pair of out-of-control steam locomotives smashing into each other head-on in a collision of epic proportions.
