It was the most ill-advised but amazing sex that Alexa had had in years. Iain still knew everything she liked, still remembered how to make her moan and how to make her scream. (She clamped a hand over her own mouth at one point to stop that from happening though. She wasn't supposed to be here and Iain's sister was in the house.)
Just having his arms around her again made Alexa feel... whole. It was cheesy and ridiculous and he smelled so good and tasted even better.
She stroked the sweaty hair of his forehead and smiled at him in the dark.
And then, when he was asleep and she couldn't even think about how she would begin to sleep, Alexa crept out of bed and got dressed as quietly as possible. (She found her bra but not her underpants - she figured they were now a sacrifice to the gods.)
Alexa crept down the stairs near-silent and then out the front door, the smell of Iain haunting her with every step.
