The night was dark. Nights normally are. The only light was Tony's arc reactor, shining in the blackness.
If Loki were to move the blankets, look down at his ankle, he'd see another light. A little light blinking on and off on the anklet wrapped around him. Shield's idea. Loki didn't doubt that he could dispose of the item if necessary – it was a goodwill gesture on his part, to agree to be monitored. If he hadn't, then this... thing that he and Tony had together wouldn't be allowed to continue. He wanted it to continue.
"Babe, I can hear you thinking too hard," Tony moaned groggily, "go the fuck to sleep."
"Sorry," Loki smirked, "some of us don't find much solace in slumber."
Tony cracked an eye open warily, "You wanna talk about it Lokes?"
Loki's body tensed in the bed beside him, "No, I would rather not."
"Hey," Tony turned towards the alien lying next to him, planting a playful nip on Loki's lips, "fine by me, Lokes. Whenever you're ready – if you're ever ready. Then we'll talk. Tonight doesn't feel like a talking night to me either..." another sly nip, "it feels like a night for something far more... interesting."
A hand slipped down his navel, caressing Loki's bare skin, thin flesh, and taut muscle. The god found himself relaxing, almost without intention.
Tony's hand slipped further down, finding Loki's manhood and coaxing it to attention. Loki moaned at the touch – absorbed in the sensuality. The noise went to Tony's own manhood, making it stir to half-mast.
They made love to arc-reactor light, their faces washed in blue colour, and mutual pleasure.
