[You'd think this passive position was practically effortless, but that was so not the case. It took a lot more focus than Aidan had imagined to just keep himself relaxed and breathing, allowing the other to thrust into his mouth without gagging or biting or choking and once he felt Helix tense, short nails raking against his scalp, he gave up on moving much at all. Instead he just held on, preparing for the hot spurt of liquid against the roof of his mouth.
When it finally came he swallowed instinctively, sucking against the hard thrusts the best he could until he was sure he got all of it. When it felt like the other was starting to come down he carefully eased off, lapping and licking at the trembling length before pulling away completely to nuzzle at his boyfriends stomach. ]
