You were the only girl in the Glade, one of the first original ten to be brought to the Maze. Alongside Alby: the leader, and Newt: the second in command, you were one of the principal three figures of authority. Alby was the leader, Newt was the one making sure everyone followed the leader's rules, and you were the emotional support figure —any and every injury, sickness, or emotional burden was shared with you since girls were (by nature) much more gentler and understanding than boys.
You had made yourself respected amongst the boys, showing that despite being a girl you were independant and able to fend for yourself. You didn't cook, because you didn't know how to, but you helped with the repairings and always checked up on the runners after their daily runs through the dangerous maze surrounding the Glade.
However, being the only girl in a place full of teenage boys could only end up in one kind of situation. Thomas was the last greenie to be brought up by the box, and he was a total lap puppy with you, he came to the Glade scared and confused —showing himself to be quite aloof— and got himself in a bit of trouble on the first day by accidentally breaking the most important rule: never go into the Maze (if you're not a runner).
And, of course, you just loved how cute he was, the way his eyes would drift to you and leave his work whenever you walked by, the way his leg would bounce up and down whenever you sat next to him at lunchime. He couldn't help it.
So that was how you had a desperate and whining Thomas clinging to you after he had seen you walking towards him while he was working on the garden. He was pressed up to your side, arms wrapped around your waist, one leg over your own to keep your thigh between his legs —where you could feel the heat coming off from his crotch and the throbbing of his erection—. "m'sorry- fuck- sorry- ngh- just- jus' a little while- jus' a little- please" he whined with glazed eyes. He was a teenage boy, this was only a natural reaction.
