She knew he wanted to fuck her too; every time he started slurping on her tits, his cock got all stiff and achey-looking in his pants. Karen didn't think it was right to let a forty-two-year old man fuck her cunt, but the tit sucking made her so horny that it had been hard to resist him. Each time a lengthy mammary nursing session had been concluded, she'd had to spend several hours with her finger in her pussy before being able to get to sleep.

And today she felt hornier than ever. Standing beside his desk with her blouse open and her bra unsnapped, Karen sighed as she felt her fleecy-haired pussy juicing and throbbing rhythmically in her panties. Oooww, getting her whoppers sucked always made her so horny! Now she really felt like fucking Mr. Grant too, not just letting him suckle her big baby feeders!

"Mr. Grant, I… I think you maybe ought to stop now," Karen whimpered. "You've been sucking on 'em for a pretty long time. I… well, you're kind of making me lose control of myself!"

Grant didn't say anything. He was too busy gorging himself on her fat, rubbery tit-tip. He opened his mouth wider, sucking the big jug farther into his mouth. Lewdly he fondled her other breast with his free hand, fanning his finger across the nipple.

"Unngggh! Oh, Mr. Grant!" The innocent, big-titted twenty-one-year-old grimaced and squirmed in front of him, feeling her pussy getting hotter and juicier. "Mr. Grant, this isn't fair. My cunt's getting all horny! Oh, Mr. Grant, please stop now! I'm gonna get so horny that I'll want you to fuck me!"

This, of course, encouraged her teacher to nurse on her giant tits more eagerly than ever. He switched tits, leaving the nipple he'd just sucked very red and stiffly crinkled, glistening with spit. Karen abruptly lost all control over herself as he sucked the second goose bumped tit cap into his mouth, slurping her big boob harder than ever.
