As he kissed her, he flicked his tongue into her mouth, and teased the tip of her tongue. Cathy melted in his arms. Her cunt started to stretch a little, accommodating his cock better.
And that's when Jimmy started to move in her, pulling his cock out to the tip very carefully and then plunging it inward, going nice and slow, so he wouldn't hurt Cathy.
'Ohh!' Cathy moaned, wriggling her hips around on her brother's cock.
The pain was beginning to go away, and Cathy was so wild with lust that she wanted her brother to really sock it to her!
'Do you like it?' her brother asked, solicitously.
'Oh, yes, Jimmy, yes. Keep pumping it in and out of me. It feels so good.'
Her words only inflamed Jimmy more. He started to pump in and out of her faster. Cathy was getting so inflamed that there were spasms in her cuntal muscles. Her little muscles gripped greedily at Jimmy's big cock.
Jimmy thrust his love muscle deeply into her tiny hole, and felt her cuntal walls close in around his huge prod.
The pleasure took Cathy's breath away. She started to arch her hips upward, matching Jimmy's downward thrusts. She felt his cock slither into her well-greased cunt with more and more ease, as her cunt was stretched by his repeated thrusts.
'Ohhh, Jimmy, cram that dick into me. Fuck me, ohhh!'
Jimmy started to thrust his cock with more speed, and strength. He felt her cuntal walls stretch a little, and Cathy was writhing with such obvious pleasure that Jimmy knew he wasn't hurting her any more.
He slammed his hairy groin into her arching muff again and again, feeling his balls churn up their heavy load of love juice.
He worked his hands under her back, and pressed her to him. His buttocks rose and feel with his rhythmic thrusting.
Jimmy knew that he was going to shoot his load any minute, and he wanted Cathy to come, too. After all this was her first time, and it should be special-something she would remember forever.
Cathy threw her legs around Jimmy's undulating waist. He was covered with sex sweat, and so was she. Her breathing was labored, as Jimmy plunged his pole into the cavern of her forbidden love. His cock began to slide in and out of her pussy more and more easily, as Cathy's cunt accommodated him more readily.
His grunts and moans became more than just whispers. They became cries of delicious anguish. He pounded into her, their sex flesh slapping together with wet, smacking noises, as they brought each other off.
Cathy was now feeling pure pleasure. Her face was radiant, her features distorted with unbridled lust.
Her hip thrusts became more and more impassioned. She tried to drive more and more of his cock into her cunt. Her tongue rolled erotically around in Jimmy's mouth as he kissed her.
Her nipples were all puckered with pleasure and they were very hard.
They sent little shivers of bliss coursing through Cathy's body, heightening the fleshy ecstasy which had possessed her.
Jimmy brought his mouth down and began to suckle on Cathy's nipple. He ran his tongue around and around on the hard little cherry-red nubbin.
He teased and tickled the tiny, hardened bud of her tit, and then started to sink his teeth into her tit.
'Ohhh, Jimmy, yesss!' Cathy hissed.
Jimmy went from one breast to the other, as his peter plunged deeply into her wet hot cavern of desire.
'Oh, lover, suck it!' Cathy screamed. She ground her hot swollen muff into Jimmy's hairy groin, loving the way his thick cock felt in her cunt.
His tongue tantalized her tits, circling the areola, and then the breast itself. Cathy continued to moan in ecstasy and romantic passion.
She felt as if she were falling in love with her brother.
As the thought occurred to her, she wondered if she hadn't always been in love with him. He had always been so good to her, and his cock felt so marvelous as it dipped deep into her honey pot, and then pulled out, only to plunge into her again.
She started to tremble all over, on the verge of orgasm. Against her quivering ass cheeks, her brother's soaking wet balls slapped lewdly.
'Oh, more, more, more!' Cathy gasped, beside herself with the wild feelings which coursed through her. 'Oh, I love your big prick in my cunt.'
They started to fuck faster and faster. Their breathing got very heavy.
It rasped harshly from their lust-constricted throats, as they wallowed in the fleshy pleasure of their impending climaxes. Their flesh smacked against each other wetly.
Cathy's juices were flowing more heavily than she had ever felt them flow in her life. They trickled out of her stuffed hole and trickled in a shiny flood down her ass cheeks, and pooled on the bed beneath her humping ass.
Her syrup covered Jimmy's big pole as it pistoned in and out of her cunt. Jimmy's eyes closed, and he pressed Cathy so tightly to his chest that she lost her breath. She didn't mind in the least. Her breathlessness only increased her pleasure.
Jimmy's balls were aching. He felt them contract, felt them unleash the torrid flood of his liquid desire deeply into Cathy's aching cunt.
'Ohhh!' Jimmy gasped, pressing his mouth to Cathy's ear. He could feel her spasms getting stronger, knew that she was coming. 'Come on, Cathy, come on! Squeeze your pussy around my cock. Ohhh, shit, it feels so great!'
Cathy started to squeal as she felt Jimmy's spunk washing against the walls of her cunt. Her hips went out of control. They slammed furiously up and down, slamming into Jimmy's wet, hairy groin, as her orgasm started to peak.
Jimmy kept shooting his hot load into Cathy, as a wild storm went off in Cathy's cunt. The slight soreness from her ruptured hymen totally disappeared as Cathy felt her cunt flooded with her brother's juices.
The puddle beneath her humping hips got bigger and bigger, as the two of them came violently.
Finally, both of their bodies collapsed, suddenly. They lay in a wet, heaving soggy, fleshy mass, locked together in their pleasure, weak from the aftermath of their violent, prolonged orgasm.
Jimmy's meat was still hard. It throbbed wildly in Cathy's cunt as they kissed and caressed each other.
'Was that good?' Jimmy asked, kissing her warm soft cheek.
Cathy squeezed his hot, sweating body against her lush curves, and moaned softly. She reached up and bit his earlobe.
'Oh, yes, Jimmy. It was so good.'
'Unh!' Jimmy grunted as he pulled out of her. He winced. Her cunt was so tight and it had provided such intense stimulation to his cock that he was sore. Cathy was sore, too. Her thighs were stained with blood and come juice.
Cathy looked down, pleased that she was now a woman.
'Oh, God, Cathy! We have to clean this mess up before Mom and Dad see it.'
Cathy laughed at her brother's stricken look.
'It isn't the first time I've stained the bed. I can just tell Mom I had a heavy period.'
'No, you can't!' Jimmy retorted. 'Last week Mom scolded you for taking the last of her Tampax and not telling her.'
Cathy sat up, feeling their combined come juices oozing out of her recently opened slit.
'Yeah, you're right. O.K. I'll do a wash.'
'I got some underwear and a pair of jeans, while you're at it,' Jimmy grinned, getting up off the bed.
'Yeah, I have some stuff, too. I know! Let's surprise Mom and Dad. Go to the hamper in their bathroom, and get their laundry. We can have it all done by the time they get home.' The young people started a wash in the washing machine, and then Cathy started to make supper, with Jimmy helping.
They had taken a shower together, and washed away the telltale signs of their indulged lust.
They sat down to dinner and talked.
'I'm so sore,' Jimmy said.
