Blow off some steam first.

You're not thinking straight. You're too worked up and there are too many things happening. Normally when this happens you lock yourself in your room, strip down and let your fingers do the work. But now you were in a public toilet and your best friend, with a little extra, was there for you to use her to relief some stress so you can start thinking about these things more closely.

You make up your mind and unlock the stall door. Upon hearing the click of the lock Megan responds by pushing the door open, looking you up and down as she enters the stall with you and closing the door behind her. She leans towards you, her face only inches from your own looking you straight in the eye as you hear another click from the door once again locking.

Megan surprises you when her soft lips are suddenly pressed against your own. A hand running through your hair while another is placed on your lower back, keeping you in place. You reciprocate the kiss, but you feel clumsy, you're embarrassed by your own inexperience in this field. The hand that was previously running through your hair has slowly made it's way down. caressing your cheek along the way and is now carefully rubbing your tiny tit through your shirt and bra. It's not very comfortable, but the sweet taste of Megan's lips balances it out.

Megan pulls away, ending the kiss. Both of her hands now on your front, unbuttoning your shirt and pulling it down over your shoulders. She looks up at you as you bite your lip in anticipation of whatever is happening next. One of Megan's hands shoots back up to your cheek, caressing it before she one again locks lips with you in another passionate kiss. Her other hand, now done with removing your shirt and dropping it on the floor behind her, moves to your back once more, trying to unhook your bra using a strange sort of pinching technique, you're too lost in the make-out session to notice how long it actually takes, but it seems "not very". As her tongue tries to gain entry you feel your bra slipping off and being pulled away, the cold air calling your nipples to attention.

"Too late to go back now" you think to yourself as you allow the foreign slippery body into your mouth, welcoming it with open... well, mouth. A strange sensation you've only really experienced a handful of times before, but it feels different. Better even. Is it because it is Megan, one of your dearest and most important friends? Or is it because you're just more horny than you've ever been before while making out with someone?
You suddenly jump, releasing a cute "EEP!" as Megan pinches one of your hard nipples. You can feel the corners of Megan's mouth turning up, and although you can't see it you know it's her insufferable smug smile that she always does when she makes you jump.

"It's time to respond" you think, your hand now roaming the front of Megan's shirt. Her Deep-ish V-neck sweater thing allowed for relativly easy access from above so you reach in with one hand, you instantly realise Megan isn't actually wearing a bra but rather a flimsy bikini top that is being held by a knot tied at the front. It takes some finagling seeing as you can't really shove your other hand in there to help but you undo the knot and you can feel Megan's breasts "breath free", going from a bit of cleavage to squishing against your hand on both sides.

As you move your hands, one inside and one on top of her sweater, to massage your friends breasts she moans into your mouth. Clearly the sort of response you were hoping for, but weren't really expecting. Megan continues making out with you and you do your best to make it feel good for her too. You suddenly notice that, while one of her hands is still massaging your tiny titty and playing with your nipple, her other hand has started crawling downwards and is trying to slide into your pants.

As Megan's hand gains access and slides over one of your buttocks and kneads it roughly it causes you slight discomfort and try to slide forward, away from the soft yet powerful hand. Again you go "EEP!" as you feel a hard bulge pressing against your pelvis. Megan moans into your mouth again and you instantly remember what that bulge really is. Megan breaks the kiss, looks at you and whispers "Are you ready for that?" and you take a second but quickly shake your head. You're not ready to go anywhere near that massive thing yet. "That's okay, it'll get it's turn." She turns her head and kisses the side of your neck, causing you to gasp. Her hand squeezes your ass again before moving further down, causing her fingers to brush against both your virgin pucker as well as your damp lips.

"M-Megs, Stick to my p-... pussy, please" you trail off as you feel two fingers carefully parting your pussy lips while a third just softly taps the newly exposed parts before they all let go again. Megan comes up for air and calmly states "Don't worry, we both know you wouldn't be able to handle that anyway". She slips her hand back out of your pants and kneels down in front of you. Both of her hands used only to undo your pants and slowly pulling it down.
Your cute panties now fully visible Megan comments with a short "adorable" before standing back up, her hands brushing against your legs on the way up, one hand going back to playing with your nipple while the other stops on top of your panties and starts to softly massage your vagina by making tiny circles around the general location of your clit.

Although you've pleasured yourself before having someone else do it is a very different experience, and when Megan's thumb actually touches your clit through your panties one of your knees gives out and you release a loud moan as Megan catches you, keeping you standing by wrapping an arm around you and beginning another kiss. You're then slowly lowered into a seated position onto the toilet, the closed lid cold to the touch. Breaking away again Megan says "I believe it's your turn again Al". She pulls up her skirt and reveals the big veiny cock about to rip a hole in her legging and bursting free. Megan stands tall in front of you, tearing a tiny hole the large penis springs into action, still not fully erect but already a couple droplets of precum have escaped from the tip.

You know what she wants, and you're willing, but with a slight tremble in your voice you whisper "I've never done that before..." and while you would normally hang your head and look at your feet due to embarrassment, you can't seem to look away from the still growing penis aimed at your face. A slightly musky smell entering your nose. Megan strokes your head, "Just do what feels right, I'll let you know what I want from you Al, so if I don't say anything you're doing the right thing" she says before giving a reassuring smile. Finally breaking your gaze from the large piece of meat hanging from your best friends crotch, looking up at her you give her a little smile, a nod and say "Alright, I'm willing to try!"

"Well, here it goes..." you raise one hand and grab a hold of Megan's cock, you can just manage to touch your thumb with your middle finger when your hand wraps around it. Guiding the tip, you quickly lick your lips before giving it a little kiss causing the rod to twitch in your hand.
