Lucy was looking down and then moved her head up to look at him. She hesitated momentarily.
"So you won't mind if I kiss you good night then?"
"No, no... n-not at all... you know I like it," Karl almost stammered with the shock.
"Yeah. I know you do," she said a little unsteadily, grinning at him. She wrapped her arms around him and then drew close before kissing Karl firmly on the lips.
"Oh God, Luce," said Karl. He felt her grinding her groin against his. His hands reached out to steady her, and so found his hands around her ass. She giggled and thrust against him again.
That was it, Karl found himself tugging Lucy's skirt upwards, Lucy giggling contentedly.
"That's my boy!" Her skirt was up to her waist now and Karl grasped her black panties and slid them down her legs, and Lucy wriggled her feet to let them drop off. He pulled own his jeans and underpants to below his waist whilst his cock sprang up, he went behind Lucy pushing her back to bend her over and pulled up her skirt again, her exposed pussy lips awaiting his cock once more.
"You bad boy!" said Lucy as he pushed his cock hard against her vulva. She gasped, opened her legs a little more and he pushed a little more and his cock found its way into her receptive pussy.
"Aaah!" she yelled.
And then Karl gripped her, and pushed gradually and slowly into his sister's expectant slit. Once inside her though, she squirmed in pleasure, and that threw the switch.
It was a furious, frantic fuck. The pent up passion of the last few weeks was finally getting its release for both of them, and Karl rapidly pistoned in and our of her, his sister yielding to his thrusts. His cock was sliding in and out of her pussy which was getting wetter and wetter, he could feel his balls hitting her entrance as he drove in and out, the dampness running down their thighs and he could hear her breath getting shorter, he could hear her higher pitched gasps. No thoughts about carefulness this time, no hesitation, he gripped his sister around the waist, holding her tight, as he approached cumming; he felt her bucking in rhythm to him, and then he could feel that she was close too, she staggered slightly which brought him to the edge, and with a final thrust pulled her towards him to push his cream deep into her passage. She cried out, and they staggered slightly in climax, clinging together. He closed his eyes as he felt his cock erupt with jet after jet of cum feeding Lucy's hungry cunt.
When he was finally spent, he held her for a further moment, before withdrawing. Karl looked down and then took a loving gaze at his sister's used pussy, and saw a bead of his cum seep out from her slit and dribble down onto her black stocking, staining it with a white sticky, creamy trail. She shuddered, and bent back up.
"You've done it again," she moaned.
"Couldn't stay away."
She kissed him on the mouth, and shortly afterwards they stumbled together into Lucy's bed.
In the early hours, he woke up, feeling horny again. He had never imagined he would be like this. His hand caressed Lucy's body, still in her tight black dress. He could smell her damp sweat, the scent reeking of raw passion mingling with the deep notes of her perfume.
"Oh Karl!"
The next thing he knew she had flicked on the light, had mounted him, and was vigorously pulling at his cock. He soon stiffened, and saw her other hand rubbing herself under her black dress.
Then she was ready, and hitched up her skirt to mount herself on his expectant cock. She was hungry, and her pussy hovered over the tip for a moment, before swallowing his cock, and, once fully enveloped, he found his sister grinding on top of him, her hips swaying, as she enjoyed the full motion of him inside her. She heaved herself and down on him, her black stockinged legs framing his body and he could feel her delicious wet grip as she slid up and down his manhood. He looked up and thought of her breasts again, wishing to drive Lucy even more crazy with lust. His hands reached up to claw at the top of her dress, pulling it down to reveal her naked beasts. He leaned up to kiss them, and again treat her nipples with his tongue. She squealed as he did so, and her thrusts getting more urgent - she was now using him, filling her unspent desires.
"God, Lucy, you are so sexy!" He loved looking up to her, to see her pert breasts sway to her movement. She grasped him by the shoulders as he lay under her, and now he began to feel her pussy squeeze and pump his swollen cock. Her pussy was rising up and down his shaft, devouring him, and he knew that he lad lit a wild fire in his sister. She arched her back in pleasure, her motions increasing the rustle of her dress and she moved up and down, impatient to be filled again.
"Lucy...Lucy!" moaned Karl, he could feel himself ready to shoot inside her again and he looked up again into her eyes strained by lust and desire, as she bucked over him.
"Come on, Karl, yes... yes, you can do it!"
He pushed up again in time to Lucy's downward pounding of his cock.
"Fuck me Karl! Fuck me! I want you, every last drop of you!"
He thrust himself upwards, and he saw her pussy busily engulfing his shaft, ready now to take all his cream, he envisioned filling her full of cum. His sister was vigorously fucking him, totally letting go, bounding up and down on him, he was feeling almost used, which felt wickedly good. He looked up to see her eyes full of lust, and her breasts crowned with hardened nipples, which triggered him and he felt the release of cum from his balls, and then jet out of his cock, again and again, into Lucy's hot wet angry pussy. She tensed and gave a low throaty moan, a powerful glow in her eyes as he felt her clenching him in, sucking out all his semen as she came too, her motion steadily slowing to a halt, her eyes closing, and then she smiled as the pleasure enveloped her.
"Thank you, little brother."
For a few moments, he could barely speak."...You're welcome."
She remained on him for another few moments, before sliding down by his side.
"You made me very happy."
"No Regrets?"
"Not this time."
