Grinning, you hold up yet another illicitly-won tome. Stuffing it into your bag, you raise your broom up, moving to get ready to leave the library - 

"Marisa Kirisame, stop right there."

You freeze in your tracks, slowly turning around to see a tall, curvy, utterly gorgeous mage striding towards you, her long hair swaying behind her, each step bringing with it a bounce. Dressed in little more than her pajamas, she was a familiar sight - one Patchouli Knowledge, owner of the library, and a common - nemesis, rival, colleague of yours. All that and many things, and - a girl who didn't seem intent to let you escape this time, a magical pink arrow crackling in her hands.

You try to muster some protests, but they fall on deaf ears. Her mind made up, patchouli hurls the arrow - and you quickly deflect it, causing it to stroke her. Groaning, Patchouli falls to her knees - you quickly stride over, trying to check on her, see what the matter was - 

"N-nnnh....Mistress~" She groaned out, slowly getting back to her feet. Hearts in her eyes now, the magus ripping at her clothes, jiggling, bouncing. Her huge, soft, *fat* breasts pressing against your own modest chest, a hand running its way down your side. ...Seems that was a love spell. With a grin, you tilt up Patchouli's chin, planting a smooch on her lips. Might as well make the most of this~

You order her to strip. "Yes, mistress! Anything for you~" Patchouli coos out with delight, casing her outfit aside. Swaying her hips from one side, bouncing her big, fat tits, hopping up and down, spinning around to flaunt her fat, jiggly ass, giving it a smack. Not a single bit of undergarments remained on her body - the magician utterly nude, happily so. 

Slowly, she strode towards you - on hands and knees, as you demanded, and pulled down your skirt. Letting your big, fat cock slide out, slapping her on the face. "M-mmh. Big, but we can make it bigger, right mistress?~" She cooed out, smooching that cock, making it swell out with size. Huger, thicker, fatter - until each of your big, fat nuts were as big as her body, your enormous cock towering over the shelves, taking up a huge part of the library.

With a playful giggle, Patchouli danced and smooched around your fat, massive dick. Smooching it, slobbering over it, and writing alll over herself - "Milk Factories" on her tits, "Love Handles" on her ass, and on her middle - Cum tank, over and over, the magician sticking out her tongue and winking. "Ehehe. Just made sure the whole world knows what to make of me now~"

With a giggle, she slowly made her way up that big, fat, trembling cock. Sloowly bouncing her massive, heaving chest against it, over it, spraying milk everywhere. Grinding her drooling slit over it, climaxing several times on the way up. "O-oh, oh. Oooh. Fuuuck yes..." She moaned, looking down at you. "P-please. Mistress. Your dumb, happy pet needs you!~"

With a hum, you oblige her. Casting a little wind spell, helping her up to your throbbing, fat cock head. She slobbers and licks over it, smooching, nuzzling her face, causing your dick to ooze out whole globs of hot, stinking cum. "A-ahh. That's the stuff!~" She happily cooes out, scooping it up with her hands, pouring it all over her body for a time - 

Before finally spreading her legs, bouncing up and down on that cock head. "E-eheh. I guess...I'm ready now. To be a cum tank. A holster for your dick. A cock sock!~" She screamed out, bouncing up and down. Faster, faster still, until - with a whine, she sloowly slid down that way too tight cock. Her big, fat tits bouncing all the way down, jiggling in front of you. Spraying creamy, rich, delicious milk all over your face~

Finally, she managed to take in - oh, half of your dick. That was a - kind of safe amount. "No, more, more!" The dumb, bimbo of a magician screamed out, bouncing down. With a chuckle, you reached up and grabbed her legs - helping her slide down, causing more, louder screams, Down, down, down she went...

Until Patchouli was little more than a living dick wrapper, stretched out over your fat, massive cock. "H-hahh...hah...ahh...I-I..." Slowly, she realizes her mistake. With a scream, with a whine, she tries to push herself back up. "Getoffgetofaghfhh..." Soon, though, she can't even scream. Cum pouring out her throat, her eyes rolling in the back of her head as she gagged, muttered, groaned, utterly skewered and bloated out by your big, fat dick~

By the time you finally let her off - she's little more than a drooling, dumb pet now. Smooching and nuzzling her cheek against your own, smooching you, grinding her body slowly against yours. "Mmmiistress..The best mistreess, ehehe, with the biggest, fattest cock. Love you, mistress!~" Not a shred of resistance or intellect left in her eyes - utterly broken now, just your pet for good!

Perhaps you should get more pets to satisfy your throbbing, fat, heavy cock sometime~
