He lot his tongue trail invitingly over her tit mounds, which were considerably smaller than Edna's, but nonetheless exciting, then back down the way his hands had just traveled.
When he got to her sex, dipping his tongue-tip into her slit for a brief moment, she moaned loudly, telling him how much she wanted to feel his cock slipping into her. It's so big, she thought. So big and beautiful!
She stroked his member as he leaned over her. Then he pulled back and knew the moment she had been longing for so long had finally arrived.
Guiding his dick by hand to her open slit, he held his breath, expelling it all at once when his dome shaped head slowly entered her honey-slick cuntal flesh.
Inch by inch slipped into her wet haven. Kathy arched her back, tears coming to her eyes. It did hurt a little. Her clit wasn't used to having something so incredibly thick inside it.
"Ohhh, Tommy!" she cried, biting her lower lip. It felt as if a burning torch was being thrust up into her snatch.
Take it slow, Tommy cautioned himself. Little by little until she gets used to you.
Kathy spread her legs as far apart as they would go, to give the teen the best access to her dripping slit. She could feel every thick inch of his cock as it filled her. She opened her eyes and saw him looming above her. The pain increased as more of his prick entered her, but he smiled down at her as if to say the pain will only last a little while, and suddenly she felt all right and didn't mind if there was pain. The pleasure which would invariably follow would more than make up for any initial discomfort.
Her cunt walls were forced to stretch more than they ever had before. But she was well lubricated and he was able to slip all the way into her without much trouble.
"Tommy!" she cried out, her back sharply arching. He was in her to the hilt and it was as a metal shaft of fire had been shoved deep into her womb. He started moving in and out of her, slowly and carefully, and the pleasure began. The pain persisted for a while longer while Kathy writhed ecstatically underneath her brother, but soon there was just pleasure.
The pressure built up as he reamed directly underneath her swollen clitoris. The sensations were like sparks of color before her eyes. She blinked rapidly and tears ran down her flushed cheeks.
"Give it to me!" she cried. "I want to feel every fucking hard inch of your magnificent cock!"
Tommy quickened his cock thrusts. Kathy couldn't keep still. The pleasure was mounting steadily. She wrapped her legs around Tommy's slim waist, feeling the shape of his ribcage against the inside of her thighs, and started humping madly back at him, completely caught up in the ecstatic electric-like current racing through her.
"Tommy! I never thought it could feel this good and so quickly… I think I'm ready to cum! Yes… yes, I can feel it… ohhh, darling, the sweetest feelings in the world… they're building… building… BUILDING!"
She slammed up to meet the teen's downward cock thrust and she exploded, cunt juice running down the teen's shaft, dripping from his nuts onto the sheets beneath him. He slammed into her with quick penetrating thrusts, his prick head entering her womb repeatedly, and she screamed with pleasure.
She had never, never felt anything as intense as the orgasm she first experienced with Tommy's cock inside her.
I've been missing so much! she thought, her head moving relentlessly to and fro. And I'm no longer a virgin!
He sliced through her inner cuntal depths, bringing her to one climax after another. Kathy soon lost count of the times she came. All she could feel was pleasure, blinding physical pleasure the likes of which she never imagined existed until now.
But I knew, secretly knew, it would be just like this. My brother! My own brother with a cock bigger than a house! My first true love!
He jabbed into her so fast his body became a mere blur. She sobbed hysterically, pleasure completely consuming her. She wanted him to stop, and she wanted him to go on like this forever, never to cum himself, just to keep making her cum. Yet she also waited in anticipation for the sensation of his jism shooting into her cunt, just as it had her mouth.
She held onto him for dear life as he slammed repeatedly into her, his balls slapping loudly against her pelvis. She reached around to cup and squeeze them.
"Kathy," he panted between thrusts. "You've got the tightest cunt in the whole world… and I thought Edna's was tight! I can feel your cunt caressing my tool… I can't hold back for much longer now… ohhh, ohhhh!"
"Keep fucking me!" she gasped. She climaxed again, reveling in blissful pleasures which burned like fire yet cooled like ice.
Her fingernails dug into his buttocks, leaving red marks, then they raked up and down his back, leaving livid red welts like zebra stripes. But Tommy didn't notice this; he was too intent on giving his sister pleasure, and of reaching his own orgasm.
Kathy was bombarded with intense cunt sensations. He seemed to thicken inside her, growing and growing until the girl could hardly breathe.
She was crying hysterically now, completely overcome by the relentless pleasure, pleasure which seemed never ending.
Then Tommy was hurled forward, his cheek pressing against hers, her breasts flattening against his chest, nipples digging into his flesh. Only the lower half of his body moved, but it was moving and rotating enough for three people. His cock rammed into her again and again. Kathy came so many times in those few minutes she thought she was going to pass out.
Finally, the teen let out a high-pitched, girlish squeal of ecstasy and his cock exploded inside her. He kept slamming it into her as he came, his thick jism filling her to the brim. He howled in pleasure, his cock jerking spasmodically inside her dripping vagina.
Her cunt muscles and membranes held his dick in a vise grip, massaging it continuously, milking him completely of his free-flowing gism.
She couldn't stop sobbing, tears streaming down her cheeks. She clutched her brother tightly to herself, feeling the spasmodic jerks of his cock as it emptied itself of its precious contents.
"Ohhhh, Kathy," he sighed into her ear and she knew he had experienced the same incredible fuck sensations she had. Together their bodies trembled as he finished cumming.
"Stay inside me a little longer," she whispered.
"Are you all right?" he asked, feeling the tears on her cheeks.
"Oh, yes! Tommy, I can't begin to tell you how good… how absolutely fantastic that felt. It was a revelation!"
He kissed her and they lay in each other's embrace until there was a knock on the bedroom door.
Tommy pulled gently out of his sister's cunt, sending goose bumps up and down her spine. He lay by her side, his semi-erect cock dribbling a long sticky string of glistening cum on his belly.
Edna opened the door and peered inside. From the way Tommy and Kathy smiled at her, she knew all had gone well. "Shall we all go for a swim?" she asked. "I've been sunbathing by the rocks and I can use one."
Tommy and Kathy jumped off the bed.
"Wear your swim outfits just in case anyone is on the beach. We can strip when we get to the lagoon."
"Good idea," Tommy said, and he pulled on his bathing briefs, now virtually dry, while Kathy put on her bikini.
"How's the water?" Kathy asked as they walked out into the sunshine.
"Just like Tommy said, calm and inviting."
They stood on the flat rock overhanging the lagoon and stripped. Kathy's pale skin was in sharp contrast to both Tommy's and Edna's beautifully tanned bodies. One by one they drove into the water, making widening ripples on the mirror-like surface, which slapped against the rocks.
Kathy came up for air and cried, "It feels terrific!" She quickly shook her head, then dove back into the water. Her eyes open, she saw myriad small fish swimming all around, darting to and fro.
Suddenly Tommy grabbed her waist from behind, locking both arms around her, pressing his dick against the cleft of her ass. She spun around and they embraced underwater. They came up for air and kissed.
