Samus moaned, her voice muffled by the water. "It feels... so good." Her hips moved instinctively with his thrusts, meeting him stroke for stroke. The hot spring's heat enveloped them both, making their skin slick and slippery as they fucked in the darkness.

She could feel herself getting closer and closer to climaxing, her whole body tense with anticipation. "Isaac..." she gasped, arching her back further as he hit a particularly sensitive spot deep inside of her.

Her breath came in ragged gasps as she felt herself spiraling closer and closer to the edge. The sensation of his cock sliding in and out of her was unlike anything she'd ever experienced before, sending shockwaves of pleasure coursing through her entire body. She moaned his name, arching her back further as he relentlessly pounded away at her probe entry.

Her orgasm built unstoppably, the tension in her muscles growing with each thrust.

Samus felt a rush of relief and excitement as the other person nodded their agreement. She reached up, unclasping her underwear and pushing it aside, revealing her bare sex to them. Her pussy lips were already swollen and glistening with arousal, ready for more touch.

Samus swallowed hard, her eyes widening in surprise as the other person revealed their impressive cocks. She glanced down at them, feeling a mixture of fear and anticipation course through her veins. "I-I'm not sure... I've never done anything like this before," she admitted shyly.

The other person chuckled softly, reaching out to gently cup her face in their hands. "Don't worry, Samus," they murmured reassuringly. "We'll take it slow, okay?
