"Don't speak and ask what I'm about to do, Nina." He said, the weight of his words an anchor to her swirling thoughts. "Just let yourself feel."
Her heart pounded in her chest, a wild rhythm of anticipation and trepidation. The cool steel sphere glinted in his hand as he held it with deliberate care, its smooth surface almost too stark against the heat radiating from her.
And then, to her utter shock, he slowly placed it against her skin, just above the sensitive ring of anal muscle, and she shivered at the sudden chill.
"Ahhh!♡~ Mnn!♡~"
Her body reacted instinctively, the muscles there tightening reflexively, rejecting the intrusion. The resistance was immediate, her body's natural defence rising like a barrier, even as her mind and heart urged surrender.
