Ianto felt like he was starving. His muscles ached, his eyes were full of sand, and his mouth dehydrated. He did eat recently but it was like he burned it up in a second. Hunting weevils gave him boost and he ran and grabbed like he was at his best, but it all went away when they stopped. Nevertheless, when Jack pinned him against the car his damn body reacted. He wanted to jump on Jack and bite him, lose control, but in spite of the blood that was thrusting through him his weariness remained. That was why he refused Jack. He expected that he would calm down when Jack released him but to his despair that didn't happen. He drove the car feeling like he was losing weight to feed his need. Damn traffic, it was so slow, he needed to get rid of this feeling as soon as possible.

It was like he was moving on pure electric energy, any time it would run out and he'd switch off. They led the weevils down to the vaults. When he closed the door and the flow of necessary actions was over he felt lost for a moment. Jack just stood there looking smug, with his hands in his pockets, his legs apart and chest popped out. He looked open and inviting. Ianto should've turned around and gone up and away, to get some balance and sanity, but he threw himself onto Jack and bit down hard on his shoulder, pulling his hips closer. Jack's hands surrounded him in a tight embrace. Jack lifted his hand to Ianto's neck and the leather of his wrist strap ended on his skin.

"Oh Ianto, we should get you something to drink and sit you down." He sounded concerned. Ianto was too tired to contradict, to pretend he wasn't wasted, so he let Jack lead him up holding him by his waist.

Jack settled him in the chair by the kitchen and brought him bottle of water. Ianto noted that this one was left over from last night. He drank it whole, and still felt thirsty. Jack crouched down in front of him, supporting himself on his knees.

"Now you need to sleep, even food will exhaust you." He really looked worried, but Ianto couldn't concentrate on that because in spite of weariness his erection didn't stop draining him. He was too distracted by Jack's mouth and his touch to really hear him. He blamed it all on his damn pheromones.

"I'll try." He turned his face away from Jack, when he reached his apartment he'd get better.

"Ianto," Jack tilted his head, watching him closely. "You have the right to be tired."

"You're not," he replied critically.

"My endurance has its downsides; besides twelve hours of sex is a proper reason to be wasted."

"Twelve?" Ianto's eyes did widen in shock. "You could just kill me instead."

Jack chuckled.

"Yeah I tend to overdo it, but you didn't seem to mind."

Ianto snorted. Jack rubbed his leg and that made Ianto twitch.

"What's wrong?" Jack frowned and then just to test, reached for Ianto's groin. That made Ianto growl. "Oh, sorry Ianto, I didn't realise. Sometimes it happens, you're over stimulated. You can't sleep like that, but I can help you with that." His grin widened suggestively. "That is if you don't bite my head off in the process."

Jack obviously decided to take his growl as a yes. He reached for Ianto's belt and unbuckled it. When he finally touched his burning erection Ianto melted into his chair with a sigh of relief. He closed his eyes and let go. He didn't even care when he started to groan loudly. Jack hands and mouth was all that he needed. It didn't take long. When he came he almost fell asleep instantly. Jack's palms on his stomach kept him awake.

"Come on I'll drive you home." Jack buckled him in and helped him up.

"I have a car." He protested weakly.

"No way in hell are you going to drive like that." Jack's phone rang.

Ianto gathered it was Gwen; while he was talking he even helped Ianto settle into the seat.

"I'll pick up Owen and Tosh," he said and hung up.

"If they asked I was mauled by a weevil." Ianto murmured while he started to drift away.

Ianto managed to climb the stairs without Jack's help. When he got in he just tossed his shoes off and threw himself on the bed. After that it was just darkness, a welcomed kind of darkness.
