The situation doesn't get any better

"Now that the warm-up is done, turn around and lets get that show on the road." The guard instructs you. Petrified, you grasp what is about to happen. You think there is no way she is putting that up your ass. It just won't fit! The guard slaps your cheek again with her cock, leaving a trail of cum that connects her tip to your left cheek. She tells you to hurry "Come on, we haven't got all day. You've got classes to go to and I have other perverts to catch." That's a bit ironic, you think. After all, who is taking advantage of two students in a locked room? Regardless, you submit to her request and turn around getting on all fours with your ass facing the guard. As you turn, you catch a glimpse of Bethany staring at your ass and biting her lower lip. The guard hasn't forgotten about her though and says "Hey girl, make yourself useful and lube him up for me." Bethany happily obliges and gets behind you. She starts tonguing your ass which is actually loose after all the pounding she gave you earlier. You can feel her large tits brushing against the back of your hips, making you feel slightly aroused and definitely not helping your situation. A moment later, she gathers some of the cum still left on her cock and smothers it all over your asshole.

All of a sudden, you hear a camera noise. You see the guard grinning as she looks at her phone. "That's going to make a nice memento. Also, if you think about letting anyone know what happened here, this is going on the Internet." She shows you her phone. On the screen, there is a picture where you can quite clearly see yourself with face covered in jizz and Bethany with her face buried in your ass. "That's a nice way to remember your birthday." notes Beth. You look at her horrified. "What?" she says "There's nothing we can do so we may as well enjoy this." Enjoy? What is there to enjoy about waiting to be fucked by a 15 inch monster, you think. Well, she isn't getting fucked by it after all, so she can actually enjoy this, you think to yourself slightly frustrated.

"It's your birthday? Now I get it! You were fucking because that was your birthday gift, wasn't it?" The guard says.

"No. It's not like..." You try to reply but Beth interrupts you "Exactly! But he didn't appreciate my gift!"

"I can't believe this. You are a very selfish boy, aren't you?" Proclaims the guard "I guess there is no other way but to make you appreciate it." She grins as she grabs her cock. "Think of this as my birthday gift." Bethany moves away as the guard walks over behind you. "I swear that when I am done with you, all you will be able to think about will be cock. " You shudder, preparing mentally for what is about to come. The guard starts slapping your asscheeks with her cock. Smack! Smack! Smack! She turns to Bethany and tells her "Come on, he is the birthday boy, right? We have to make sure he is having a good time." as she points to your face. Bethany brightens up and starts walking towards your front. You can see her cock swinging from left to right, still glistening from her cum. She smiles and says "Happy Birthday, John" as she shoves her cock down your throat. Simultaneously, you feel the guard aligning her cock with your ass and entering you with ease. You swallow about 5 to 6 inches of Bethany's cock while the guard manages to get about 10 inches of her cock in your ass. They stay still for a couple of seconds enjoying the feeling, then start slowly moving in and out of your orifices. As you slowly feel their speed increasing, you think to yourself "This is going to be one wild ride."
