It is a wild ride

Over fifteen minutes pass with all you hear being moans and noises. You hear the guard's balls slapping against your ass as she manages to get her entire cock in. You hear Beth's balls slapping against your chin as you gag while deepthroating her. Your chin is covered in spit and precum which has slowly started to flow from the tip of her cock. Although you are being spit-roasted like a seasoned buttslut, you have to admit you like the feeling. There was pain initially, but it subsided and gave way to a very specific type of pleasure slowly building up in your crotch and ass. Besides, your raging hard-on shows that your body definitely likes this.

"Alright" the guard says as she slaps your ass "Time to change positions." She pulls out of your ass with a loud pop leaving you with a strange empty feeling. She lays on the ground and motions you to come over. You get the hint and you walk over to her, your asshole gaping and your face and upper chest covered in a mixture of spit, precum and actual cum. You slowly squat over her erect monster and align your hole with its tip. You are glad she picked that position as at least it allows you to control the pace. You start lowering yourself and you feel her tip slowly entering you. You hear her moan and you can't help yourself but moan as well...

Without warning, you hear several loud knocks on the door. They startle you and you lose your footing, dropping down on the guard's cock. You feel her whole cock filling you up as your balls slap her crotch. You gasp, spurting a little bit of precum from your own cock. So much for controlling the pace you think. "Open the door. I am expecting visitors." the guard tells Beth as she gives her the key to unlock the door. Your eyes follow Beth as she goes to the door and unlocks it. To your surprise, you see several of your teachers on the other side. There is your Maths teacher Jasmine, a petite 5'6 Asian lady, your Gym teacher Aliyah, a 6'2 tall Ebony , and your Physics teacher Virginia, a 5'8 redhead with round breasts and a big butt you've been lusting after for the last several years. Intriguingly, Jimmy, a skinny boy from the year above who never managed to grow past 5'6, is also there. You look at him wondering why he is here and he grins back at you. You suddenly realise how slutty you look, sitting naked on the guard's cock with bodily fluids sputtered all over your face and body.

As soon as the teachers enter, Bethany shuts the door and turns the key again. Your teachers say in unison "Happy Birthday, John! We come bearing gifts!" and drop their pants revealing some very interesting gifts indeed.
