Chapter 4: Climax
Ellie gripped her sister's waist with tensed, determined fingers, wrapping her legs around the other's muscular thighs as they slid together on the white sand.
"You always think you can best me," Ellie grunted, her deep blue eyes blazing as they locked onto her twin's equally fiery gaze. "But you've never managed it yet."
The other Ellie snarled, a growl escaping her lips as she threw all her weight into pushing her sister off her, sweat beading on her forehead from the exertion.
Her labia ached, rubbed raw with hours of wrestling. But she wanted more, this was a battle of wills between the two of them, and she was determined to win.
"I'll be the one to break you, Ellie," the other Ellie said through gritted teeth. "You'll remember this moment for the rest of your life."
Ellie sneered in response, gritting her teeth as she too threw her strength into their battle.
"We'll see who breaks first."
Their clits ground painfully into each other, swollen and red, the tender nubs throbbing with a desperate need to explode into an earth-shattering climax. Each of them refused to give in, insisting on dominating the other despite the white-hot burning agony that was threatening to tear them apart, muscle by muscle.
Their pussies smashed together in a brutal, raw fuck, each thump and grind driving a spike of heat through their cores.
The electric pleasure intensified with every frenzied movement, pulsing through their swollen labia, their slick flesh shimmering in the sun's waning light. Their clits, flushed with need, mashed hard.
Ellie's back arched as her twin sister viciously bit down on her shoulder and sank her teeth into the flesh in a powerful yet playful gesture.
She cried out in a mix of pain and the overwhelming pleasure coursing through her veins. Then she sank her own teeth into her sister's soft neck to meet on on even ground. They clawed into the others back, deep red lines and both Ellies sucked each others blood.
The sight and taste of it only heightened the erotic allure of what they shared. Their hips swiveled rhythmically as their intertwined groins met the resistance of their swollen, throbbing clits. Each scrape of their clits against each other sent electric jolts through their bodies and they howled their anger and frustration as their desires pressed to the surface.
As they continued the brutal fucking, their limbs shook and legs staggered as they maintained their frenzied pace.
