A cave!

The naked, shivering couple spot a nearby cave and head towards it, clinging to each other for warmth.

"Wait, what if someone's in there? They'll see us," Hilda whispers, her body shivering from more than just the cold.

Hunk takes a deep breath, his cock twitching at the thought. "W-we can't help it," he finally says. "Stay behind me, no sense in us both exposing ourselves." His cock twitches again at the thought of someone else seeing him like this, and his face gets a little redder.

"Oh no," Hilda says, herself getting excited at the prospect of being seen. "I couldn't let you face such dishonor. Let me do it. I'll go." She rubs her thighs together and suppresses a moan as she steps forward.

"No!" Hunk yells. He's keenly aware of his hardon, and too embarrassed to let her see it, so he puts an arm out to stop her, unintentionally grabbing Hilda's breasts. His face turns even redder when he realizes what he's just done. It goes full crimson when Hilda closes her eyes and moans.

"OOOOHTAKEMENOW..." Hilda mumbles, before regaining her shame and blushing herself. "I mean... let's both go, hand in hand. That way, neither of us should feel embarrassed..."

Her logic breaks down as her juices rev up. She bites her lips and her legs tremble.
