It's in her best interest to leave

"I can't think of anything I'd rather do than fuck you all day and night Grace," you say as you cuddle her. "And we will. But if people find out about us this could all be over."

"Over?" she asks with a surprised whimper, pulling her face back to look at you.

"Over. They might fire me, or worse, and I'd have to leave and never see you again." You feel a momentary guilt for manipulating the girl, but you reason that it's in her best interests as well as yours.

"That can't happen," she whimpers, stroking your cheek. "It can't. I need you again Mr. Carter. I have to have you."

"That can happen Grace, but if it's going to happen you have to leave now."

"Yes..." she whimpers. "I understand. But later...later you'll fuck me again? And teach me? I need it Mr. Carter. I need to learn."

"I will," you promise, sliding out of her embrace and standing up, helping her to her feet. "Put your clothes on sweetheart," you urge her, handing her shorts and top to her as you hurriedly tug your shirt on. "Come on darling there is no time to lose."

Anxiously biting her lip she obeys, pulling her top over her head to hide her sweet little breasts, then tugging her shorts up her long toned legs. She insists on another embrace before you urge her to the door, shoving her tongue halfway down your throat before you can open it.

Brian's door is open, and you hear no other sounds in the cottage. You almost push Grace down the stairs, then stop as you see Brian sitting in the living room, calmly sipping a cup of coffee and smiling knowingly at you. Grace looks at you with worried eyes as she sees him, her chin trembling.

"This is Coach Watts. Coach, this is Grace Mathewson. She was making amends for vandalising my room. Did you finish punishing your student?"

"I did, and sent her on her way," he grins. "She was very remorseful. Miss Mathewson seems to have been very contrite."

Grace is blushing furiously, her pale skin almost scarlet with her embarrassment. "I'm sorry Coach Watts, I was trying to make it right. What I did I mean. The painting. That was so wrong. I don't know what got into me."

"I think we all know what got into you Miss Mathewson," he chuckles. "At least twice from the sounds of things. You're a very enthusiastic penitent." It doesn't seem possible for Grace to blush any deeper but she manages it.

"Mr. Carter...He was...Oh God! I'm so sorry!" she whimpers, tears starting to stream down her cheeks. She turns to you, burying her face in your chest, wrapping her arms around you.

Brian gets up with a smile. "Don't cry Miss Mathewson. I'm sorry for teasing you. But you do blush so prettily."

She looks over her shoulder at him, her sniffles slowing. "You won't get Mr. Carter in trouble? I don't want him to get in trouble for me."

"Mr. Carter and I are friends," he says, looking at you with a genuine smile. "Teammates in a manner of speaking. Teammates don't deliberately get each other in trouble."

"You should go now Grace," you tell her, wiping the last of her tears from her cheek and pushing her towards the front door.

"I'll be back," she purrs, coiling into a last embrace and staring up at you with wanton eyes. "I'll be back for another lesson Mr. Carter."

"I'll be waiting," you reply hurriedly, breaking her embrace and opening the door, watching her scamper down the path before you close the front door.

When you turn, Brian is chuckling. "You don't do so bad for a supposed old man," he laughs, raising a palm for a high five.
