"L-Le...n..." She gasps, her eyes still closed as she tries to catch her breath. The sensations from his cum inside her are still coursing through her body, making it impossible for her to think clearly. "I'll do whatever you ask... I just want this feeling again..." Her voice trails off, replaced by a soft moan as he continues to hold her close.

"Y-Yes..." She answers breathlessly, her eyes still closed as she tries to process what he's said. The feel of him moving inside her, so big and hard... it makes her body tremble with desire. "I want that... I want you both." Her hips move restlessly against him, her legs wrapped tightly around his waist in invitation.

As the pleasure mounts inside her, Robin begins to lose control. With a shout, she comes hard around Mark's dick, her whole body shuddering with the force of her orgasm. Her muscles clench tightly around him, milking his cock as she rides out her climax.

"Mmm... that was... really good," she gasps, trying to catch her breath. "But I still think you could've done better." She grins up at him, a satisfied gleam in her eye. "

As Mark fills her with his seed once more, Robin moans loudly, arching her back and pressing their bodies even closer together. She holds still, letting him cum deep inside her as she relishes the warmth spreading through her chest. When he finally finishes, she collapses against him, breathless and sated.

"Well then," she says with a satisfied smile, "I guess I can't really complain about that now, can I?"
