Not immediately

Titus held the helpless girl's head under water as he pounded into her, savouring her frantic struggles for life. He grinned savagely at Agrona as he **** her sister, seeing horror and despair mark her haughty face as she stared at the scene unfolding before her.

He felt Dierdre's struggles weaken, and with a sudden move he pulled her head out of the water while continuing to impale her tender cunt. She gasped frantically, sucking air into her shuddering body.

"She's an entertaining fuck," he observed conversationally to Agrona. "Especially when she's at the point of drowning. She seems more motivated." The bound Celtic woman bit her lip, saying nothing, watching with eyes sparkling with hatred and fear.

He kept thrusting into the quivering girl, letting her catch her breath, and hearing her gasps gradually replaced by moans. He felt her cunt squeeze his **** meat, and she was starting to writhe her ass against him, either in unexpected pleasure or in an attempt to please him. Her grinned savagely at Agrona again as he wound one fist in Dierdre's sodden red hair.

"It think this sow is enjoying it," he laughed cruelly. "She's quivering at the feel of a Roman cock. She'll be coming soon."

Agrona made no reply, simply staring at him with eyes full of fury.

"Yes....very soon," he grunted as he thrust. "And so will I. Lets see how much the sow can improve with a little encouragement." With that he pushed Dierdre's head under water again, holding her hips with is other hand and fucking her fiercely.

He could feel her convulsing as he reached the critical point, her tight sheath milking and squeezing him as her body fought for life. With a roar of conquest he exploded in her, filling her virgin cunt with his scalding seed, pumping himself dry in her as she was racked by spasms of orgasm and encroaching ****.
