synopsis: macklin is upset when he realizes readers new coach is young and attractive
macklin has been hearing you talk about your new coach, how nice he is, how patient he is; unlike the other coaches, and how much he's been of help. what you failed to mention, was that he was in his 20's, not middleaged like mack assumed.
macklin decided to show up at your practice since his had been cancelled. he quickly realizes the man on the field was not a teammates boyfriend or a groundskeeper, but rather your coach. he has dirty blonde hair that mack thinks needs a haircut, greyish blue eyes, and an athletic build. nonetheless, he is not happy.
mack's jaw clenches as he watches your coach adjust your hips to batting position, clearly unhappy. he should be the only one who gets to touch you like that. he keeps quiet and lets your coach cuck him help you practice. he knows how important softball is to you, and he doesn't want to mess that up for you. he watches the rest of your practice, his fists tightening as he watches your coach touch your hips and shoulders.
when your practice is finally over, you step off the field, hair messy as you walk towards macklin and hug him. your coach steps off the field, and macklin notices the slight hesitation in his step, and how his shoulders seem to slump and his eyes darken. your coach walks over to you and mack, and you let go as he comes to a stop in front of you two.
he extends his hand for a handshake from macklin, and he takes it, maybe just a little too tight. "coach isaac, this is macklin, my boyfriend. macklin, this is coach isaac." you say after a few seconds of intense staring occurs. "i didn't know you had a boyfriend." isaac says bluntly, his jaw ticking as he looks mack up and down. "well, she does...uhm, we're gonna go now." mack says uneasily, even though he's taller than isaac, he still feels threatened.
by the time you two get to the car, you've noticed mack's gloom. "mackie, are you okay?" you ask. "you didn't tell me he was our age." he whines, his green eyes glistening with threatened tears.
"baby, you don't have to worry about him."
"he was touching you like you were his- and i just-."
"baby, i'm sorry you felt that way. i'll give you cuddles when we get home."
"and i can choose the movie?"
"i was gone for two hours."
