Karen wrapped her right hand around the fat root of his organ, again growing hornier as she felt how fat and stiff it was. Eagerly she started whipping her right hand up and down the tool as she sucked the knob, jacking off his boner into her mouth, trying to make him squirt out a really big load of jizz.

"I'm cumming, Karen!"

His rod grew even stiffer, nursed to total hardness by her madly pumping first, her wetly sucking, smacking lips round the flared knob of his boner. Suddenly a gigantic stream of cum spewed out, splattering on the roof of her mouth. Karen gurgled, nearly choking herself as jet after jet of hot, tasty prick juice spewed out of his big, throbbing pisser.

It had obviously been a real long time since her teacher had relieved the pent-up load in his balls. Either that or sucking on her stiff nipples had made him hornier than she'd thought. One way or the other, though, his big boner was really unloading now. Karen feverishly kept sucking and jacking for nearly a minute, swallowing so much cock spew that her belly felt warm and full, continuing to suck happily on his disgorging prick until she'd lapped the last traces of cream from his prick.

"Oh, fuck, was that good!" Her horny teacher sprawled back on the chair, sighing his red-faced pupil finally took his cock out of her mouth. "I'll tell ya, Karen," he grinned. "I'm really going to miss you!"

"I… I guess I'm going to miss you too, Mr. Grant," Karen murmured, feeling ashamed of herself again as she licked the cum from the corners of her mouth. "I… I don't think I did you right by sucking you off like this, but… well, you helped me so much in school and everything… anyhow, thanks so much!"

"Good luck finding a job!"

"I hope I don't need it."

Grant just smiled warmly, looking at his student's huge mammaries, licking his lips as he stared at her spit-glistening nipples. A moment later, Karen was stunned to see that his boner was getting really big again. She'd never thought that a man his age could get two giant hard-ow in a row, but he was. Soon the rod was as stiff as it had been before she'd started sucking, shining now with a lurid mixture of saliva and jizz.
