Albus's mind clicked softly, disengaging from conscious thought altogether. His whole world became the smooth of the tops of Gellert's thighs, the heat that came off of him in waves, the dizzying slide of his hands-- and then, the hardness of Gellert's cock against his lips, threatening to renew his own arousal all over again.
At first it was Albus's lips, then his tongue, and then both twining together as Albus's mouth meticulously revisited every inch of Gellert's erection. Albus's lashed fluttered faintly, almost surprised all over again at how exquisite his mouth felt when wrapped around Gellert. Bringing the tight ring of his lips to the base of Gellert's cock, Albus moaned softly, a hand shifting to pull the backs of his nails along Gellert's balls. His every move, each circle of his tounge, each tease of his fingertips, and each stroke along Gellert's length carried the trappings of an affection pressed flush against adoration.
It was so convenient that his mouth was occupied, because with his thoughts to suspended, it would have been too easy to have given voice to the things he'd kept so carefully tucked away for years now.
