Go to the bathroom to clean yourself up

Class ended and thankfully the teacher didn't ask any questions about the puddle left in and underneath your seat. "She must not have noticed" you think to yourself. Students all around you are getting up and packing their things. You begin to do the same still sitting down when all of a sudden you see her. She walks past your desk and she is huge. She has dark lustrous hair and is at least 6 inches taller than you. Her hips are curvy and you can see her figure as it hugs to her robes. Then you see it. Her cock is tight against her robes as she clearly has a boner and it's wide. As she walks by she is so tall that her crotch is head-level to you as you are sitting in your desk. As she brushes past you get a faint whiff of her musk and let out a little whimper. You want her to just bend you over your desk and fuck you right there.

As she is walking out of the classroom you gather your things quickly and start to follow. As you exit the classroom into the hallway you see her head into the bathroom and cannot believe your luck. You enter the bathroom as well, not too far behind. You hope you can both fix each other's mutual problem.

As you walk in you see her standing at a urinal to your left so you decide to position yourself in front of a sink opposite of her. You bend over slightly and make sure your ass is the first thing she'll see when she turns around. It works because as soon as she turns around she freezes in her tracks. Her eyes look focused and her mouth is slightly open. You look her dead in her eyes and wiggle your hips before walking to your left and going into a stall.

Before you could close the door her hand slams the door still and she steps in with you.

"Can I help you?" you ask as you back up and grind your ass against her member and are reminded of how wide it is. She instinctively grabs your hips and chest and starts to caress you. She squeezes you close and you can feel her breasts pushed up against your back.

"Don't act dumb... I know what you want. The whole class saw what you were doing. So let me in". She says softly in your ear while still grinding your backside.

"Ohh I don't know. We don't have that much time until class starts"

"Fuck class I want your ass" she says as she starts to undress you. She is a little rough and impatient which only turns you on more to know how much she wants you. She peels back your lower garments of your robe just to see the cum Leshaun left when she pumped into you in class. "Good this should slide in easy" she says as she now takes her pants off. "Hold still" she says as she lines up her wide member to your entrance. "Please give me your dick" you say moaning. She starts applying pressure for her initial push. Luckily its still loose from when Leshaun took you and her cum is acting as lube. It doesn't matter though because her cock is too wide. You groan a little and she just says "shhh relax babe relax". Then without warning as soon as her head goes in, her entire length goes in. You give out a loud yelp due to the sudden intrusion and she just moans. You cover your mouth realizing people in the hallway could have heard that. She starts to slide in and out and you turn your head to look at the giantess taking you. Her eyes are closed, her face is a little scrunched and her mouth is open letting all of her moans escape. You moan sharply and say "I'm about to cum". You have never taken a dick this wide before and its pushing and rubbing against your prostate like nothing you have ever experienced. Her moans and her grabbing you is not helping either. Not to mention over the last hour you were getting assaulted by Leshaun and you never got to cum. "Ok... I'll let you cum" she says as she immediately grabs your cock with her hands and squeezes tightly. She goes towards the base and starts stroking you as her relentless thrusts don't stop. You are in heaven right now. "Go ahead" she says between thrusts and moans. "Cum for me. I want you to cum while you know your ass is being conquered by my big fat dick". This pushes you over the edge and you spray the wall in front of you and moan loudly. You also start bucking your hips to massage your love button more. "Oh fuck. Me too" she says as she hilts you and starts pumping your insides full of her warm love juice. She holds you close and doesn't let you go. "Take it. Take every last drop of my cum" she says as she exhales in your ear sharply. After about 30 seconds of stream after stream of her hot cum painting your insides she finally deflates. It slowly starts pulling out as her size starts to shrink. When it finally falls out you let out a whimper. She turns you around and starts to make out with you. "Thank you" she says before letting you go and leaving you in the stall.
