The next morning

Late into the night you continued to flood Sofia's slender body with your potent semen, filling her womb to overflowing. Your balls satisfyingly empty, the two of you fell asleep spooning, your softened but still impressive cock plugging up the entrance to her pussy as your sperm did its work trying get your little sister pregnant. You were completely unprepared for the rude awakening you received in the morning.

"It's time for you two to get up!" you hear a familiar womanly voice say as the sheets are ripped from your body. Startled, you and Sofia fly awake to see your mother standing over you.

"You two aren't skipping school to fuck again all day! Your pants and moans all last night could be heard through the walls and had your father so excited he fucked my ass for over an hour before he was satisfied."

"But mom..." Sofia starts, getting up out of bed and standing next to her mother, the copious amounts of cum already starting to run down her legs and drip on the floor.

"Sofia, put some panties on right now! I don't need you leaking cum all through the house again. It's bad enough your brother shoots horse sized loads and ruined your room, don't get it all over the rest of the house."

"But Mom, it feels so good when he shoots inside..."

"I'm sure it does sweetie, but please don't destroy the rest of the house. Also, you two have to go to school today. The secretary called me yesterday and asked were you two were!"

Sofia sighs and finally says "Okay mom," before stepping into a pair of panties and pulling them up, the crotch nearly instantly soaking through with cum leaking from her well used pussy. Really, all she wanted to do was stay in bed all day and let her big brother and his nice cock breed her.

"Hmm, we're going to have to find you something more absorbent" your mother says, rubbing her chin as she looks at Sofia's crotch.

Getting out bed yourself, having listened to this ridiculous conversation that shouldn't be possible, you head to the shower. Washing off the sticky mess from last night's activities, you dress nicely for school, feeling refreshed. Sofia and your mother are nowhere to be seen as you enter the kitchen and eat a bowl of cereal for breakfast, dumping the bowl in the sink, and leaving just in time to catch the bus.

You sit in the very back as normal, enjoying the moment of solitude. Of course, the very next stop a familiar student gets on the bus and makes a beeline for your seat.

"Hey stud" Emma says softly, winking and pushing you over a bit so she has room to sit.

You quickly look around the bus. There's only about a dozen other people on it, and the two of you are the only ones in the entire back half. Emma is nothing if not brazen. You take in her appearance. She's wearing her field hockey uniform, a short pleated skirt with a checkered pattern of the schools colors, and a short sleeved jersey tight enough that shows off her toned athletic body and C cup breasts. The knee high socks complete the outfit. You have to admit, an athletic girl in her uniform is damn sexy.

"Hey Emma" you say cautiously, remembering the other day.

"We got a big game today that will determine state playoffs. Always good to be able to leave school early" she says, wiggling closer. You watch as the grabs the hem of her skirt, slowly lifting it, showing more toned thigh until it finally reveals her crotch. She's wearing panties this time, a thong that barely covers her smoothly shaved pussy lips. The upper part is transparent, and you can see a small, triangular patch of dark pubes through the material. Your cock immediately goes rigid at the delicious sight.

"What do you think? Do my cute little panties match my uniform?"

You gulp and nod, and now your erection is clearly straining your pants. Emma's eyes look down to your crotch and she smirks.

"Hey John" she says, moving so close her lips are pressed softly to your ear. He hand moves to your crotch and strokes you through your pants. "Like I said, its a big game today. You think maybe you could let me bounce up and down on that big cock of yours before we get to school? You know, for luck?"

"Fuck Emma" you groan out, closing your eyes. Another ridiculous situation you find yourself in, thanks to that contract you signed. Did the free use work both ways? Could you not only charm and fuck any girl you liked, but girls that liked you would come to you as well? It's something that would require further investigation.

"Yes, fuck Emma" she says huskily, fumbling with your belt and zipper. You lean back to give her easier access, your cock eager to be free of its confines. Soon, Emma succeeds, and your rock hard length springs free, jutting up proudly.

"Wow, it looks even more impressive than last time" she says in awe, her smooth hand instantly going for your cock and stroking it.

Emma leans over and quickly takes you in her mouth, working your erection up and down with precision. Once sufficiently lubed with her spit she pulls off of you and stands up, pulling her thong to mid thigh and maneuvering her body so that she's now squatting between your open legs. You hold the base of your cock with one hand to aim, and place another on her ass to guide her as she lowers herself. You run the head back and forth against her smooth pussy lips for lube before placing the tip at her opening. As you let go of her ass the athletic girl takes the hint and slowly lowers herself, biting her lip to keep from crying out in lust as she impales her near perfect pussy on your thick meat rod. You can't help but lift the back of her skirt, your eyes drinking in the view of the sex teen fully impaled on you, her tight pussy lips wrapped tightly around the base of your cock.

"Just a second Emma" you strain out, grabbing your phone and taking a few pics. She wiggles her butt and smirks when she realizes what you're doing.

"Make sure you send those to me too" she says huskily, winking at you as she starts to bounce up and down, slowly, savoring the deep penetration.

"Damn you're big" she moans out, picking up the pace as her increasingly wet vagina provides lubrication for your cock. "I feel like the tip is all the way up in my belly."

"Can't help it" you groan out, placing your hands on her waist and helping her bounce. "When a girl as sexy as you wants to do this with me there's no way I'm going to be anything other than rock hard."

"I'm glad you think I'm sexy. If that's the way you feel, this doesn't have to be just a bus thing. We can meet up and fuck whenever you want John."

Your cock jerks at her words. It's arousing and ego boosting hearing someone as hot as Emma wants you too. You feel her squeeze your cock with her pussy in response. Slowly the minutes tick by, the rest of the bus oblivious as Emma continues to bounce on you so deliciously. But all too soon you recognize familiar streets as the school approaches. You have maybe two minutes at max. Its been seven hours since you last came, so you know your balls are fully recharged and ready to dump a truly massive load. You grab Emma's waist a bit harder and make her bounce faster. You can feel her squeezing you and hear her pants and soft moans of lust as she takes every inch of you on each bounce.

"Gonna cum real soon" you say through gritted teeth.

"Me too, cum inside me John, let me feel you shooting inside me again!" comes the strained reply.

You don't have to be told twice. With a grunt you thrust your hips up as your hands pull her down to slam to maximum depth inside her tight pussy. You hear her gasp loudly as the first massive blast of your potent teen spunk fires deep into her belly. The feel is enough to trigger Emma's own orgasm and you feel her pussy spasm, quivering with each thick blast of cum as her hungry snatch milks you for your seed.

"So hot, so good" she moans, eyes closed as she savors the feel of her insemination.

It's incredible watching Emma go from being a flirty, popular girl that you enjoy conversing with, to a quivering mess eager to be filled with your seed. The rush of power only adds to your excitement as you continue to fire thick ropes of sperm into her welcoming belly.

The two of you come down from your orgasm just in time as the bus turns onto the final road, the school ahead of you. You lift her skirt one more time and take another picture of her cum coated pussy lips gripping your softening cock. You poured a massive amount of cum inside Emma, much to her enjoyment. Now you had to get her off your lap without making a mess on your pants.

"Emma, squeeze your pussy tight as you pull off me, I'll pull your panties up."

She nods and does just that. You're able to yank up her thong just in time to catch a big glob of cum from leaking out of her and onto you. She smiles at you as she takes over and fixes her underwear in place. However, the thong isn't nearly absorbent enough to soak up your massive load, and already the crotch is soaked through and a trail of cum is running down each leg. You don't think you'll ever get tired of the sight of a well used pussy leaking your cum.

"Mmm you shot so much in me" she teases, standing up now that the bus has stopped. "I feel nice and full. We're definitely going to win today now that you blessed me with your luck."

As you're wiping your slimy cock with a paper towel you had in your bag and getting situated, she leans forward and kisses you gently on the lips, much to your surprise.

"Definitely feels better without a condom. I think I'm hooked. I'm gonna enjoy the feel of you leaking out of me all day John."

"Wait what? You're on birth control right?" you ask, pondering her statement.

"Nope!" Emma says smiling, winking at you as she turns and walks down the aisle of the bus to get off at school, leaving you to ponder her words.
