I clenched around her, pushing back to meet each drive. The angle hit deep, pleasure sparking through me. Her hand reached around, fingers finding my clit, rubbing in tight circles. "Cum for me while I fuck you. Show me how much you love it."
The dual stimulation was too much. I shattered, ass spasming around her cock, cries filling the room. She didn't slow, pounding harder, her knot beginning to swell. "Feel that? It's growing. Gonna lock us together soon."
"You a-are... merciless..."
"But I am gentle, aren't I?"
"Yes..."
"So, why am I merciless? Do you want me to be merciless?"
"No!"
With a powerful thrust, the knot popped past my rim, stretching me impossibly wide. I screamed, the fullness overwhelming, another orgasm ripping through me. Locked tight, she ground against me, her cock pulsing as the first hot jets of cum shot into my ass.
