Make them come to you for advice

You decide the girls should have the urge to ask you for advice. You start, "Amber, Jessica, and Claire all decide that I am the person who can help their problem. They are willing to do anything, anything, for even a chance at the girl they like, including submitting their bodies to me. While they remain in love with the girl of their dream, my touch feels electric to them and turns them on."

All three girls see you and start running up to you. Each one begs for a second alone with you, all the while looking lovingly at their love and with disgust at their admirer.

You decide it's time for some fun so you say, "Calm down, calm down, girls! Girls, move to separate corners and I'll talk with all three of you separately. I think I can help everyone of you."

The girls each stomp their feet at you and move away in a huff. They look absolutely adorable when they are angry.

You move over towards Amber. You know she wants Jessica but Jessica can't stand her. You lean over to start move your hand over her flat stomach. She winces and looks at you but you respond, "Hey! You want my help or not? I deserve a little something." You continue talking to Amber while you start to slide you hand down her skirt to play with her pussy. Amber leans back into the locker and looks up to moan as you discuss the plan. "Look, you know that you want to be with Jessica but Jessica wants to be with Claire. So I'm thinking I can convince Jessica and Claire to have a foursome with me. It may take some time but I'll tell Jessica that Claire is there, and Claire that you are there. But I'll have everyone else wear noise-canceling headphone and blindfolds. What I'll do then is fuck Jessica hard in the ass and give you a strap-on so you can fuck Jessica and make out with her. After that, I can fuck you in the ass and not tell Jessica that she's fucking you and not Claire."

Amber beams a smile at the idea. You pull your soaked fingers out of her pussy and spread them to her lips. She sucks off her wetness from your fingers as she nods and says it's a deal. You add, "Of course, to make sure you can take my cock in your ass without making any noise, we should start practicing after second period. I mean, it's the least I can do for you."

Amber kisses you on the cheek and agrees. She gives you her number so you can practice fucking her ass as needed before she walks off.

You then move over to Jessica and suggest the same idea but with her fucking Claire and thinking about Amber. She gets just as wet at the idea as Amber did. She promises to meet you after third period so you can start readying her ass as well.

Finally, you move over to Claire and make the same suggestion. She is absolutely soaking at the idea and agrees to meet you after fourth period so you can start on the ass fucking.

You debate whether you should be the only one in the foursome or just sell the girl's holes freely.
