When Jack sneaked into Sam's room that night, he wondered if Nan's words were echoing a bit too much in his mind. He gently pushed the door open and paused at the entrance of the room.

"Sam?" he ventured.

Truth be told, he wasn't entirely sure why he was there. Of course, he wouldn't turn down sex if the opportunity arose, but deep down, he mainly wanted to spend some time alone with her after being apart all day.

Sam emerged from the adjacent bathroom, a simple towel wrapped around her body, her skin still dry.

"Sir?" she asked, probably surprised to see him there.

Jack plunged his hands into his pockets and rocked on his feet, his gaze roaming the room to avoid resting on her. "We're off duty, Sam, maybe we can drop the 'Sir'?"

"And what if I want to keep using the term... Sir?" she gave him a playful smile before turning to head back to the bathroom.

Jack reacted immediately, closing the door behind him, he crossed the few meters separating them in long strides. Reaching the bathroom, he undressed and hurried to join Sam, who was already in the shower.
Pressing his chest against Sam's back, he devoured her neck with long kisses, growling as he felt her press her buttocks against him.

"You're going to drive me crazy," he told her, slowly moving up her body to caress her breasts.

Sam threw her head back, resting it against Jack's shoulder, offering herself to him with a rough moan. "Maybe you already are, crazy," she murmured, biting her lip as she felt her lover's fingers explore her intimacy. "Two nights in a row, that's a first," she pointed out.

He didn't respond immediately, contenting himself with caressing her body with his fingertips. "I must have missed the memo," he breathed, capturing her earlobe between his lips.

A shiver of desire ran through Sam, and she giggled in response to his silliness.

"You know," he resumed, his hand moving up the young woman's belly. "Since our first meeting, I've always wondered what it would be like if you let go."

Sam frowned. "I know how to let go, Jack."

He moved his hand up to her breasts and pressed his erection against her buttocks. "No, Sam." His skillful fingers played with her nipples. "All this time... You've climaxed, sure, but I've never seen you truly let go."

Sam stifled a mocking laugh. "Says the man whose mask I've never managed to break."

Jack smiled, his lips pressed against the skin of her neck. "We're not talking about me right now," he replied softly.

His right hand descended to her intimacy, finding it wet, and he couldn't hold back the automatic thrust his body made in response. Sam placed her hands on the wall in front of her, arching a bit more toward him.

"I know how to let go," she whispered breathlessly.

He brushed her clitoris with his fingertips and bit her shoulder at the same time. "Oh, really?" he asked, kissing the skin he had just bitten. "Then tell me what you're thinking, without lying."

Sam froze for a moment. She had two options: tell the truth or lie to flatter his ego. She slid a hand between their bodies and gently grasped his erection. "It's not..." she began, hoping to distract him with her actions.

"Tell me, Captain," he softly ordered.

"Alright," she moaned, releasing his erection to place her hands back on the wall. "I was thinking about gravitational collapse. Matter being compressed into a point of infinite density... Oh." She suddenly stopped as he slowly penetrated her.

"Continue," he whispered, setting a slow rhythm.

"This..." Sam moaned, caught her breath, and continued. "The point of infinite density is called the singularity, where the known laws of physics cease to apply normally... My God, Jack."

She was unable to finish her explanation, overwhelmed by the sensations he was bringing to her body. Arching her pelvis further toward him, Sam responded to his thrusts with enthusiasm but was surprised when Jack's hand moved in front of her to turn off the water as he suddenly pulled out.

"Come," he growled, taking her hand and leading her out of the shower to the bed.

He kissed her tenderly as he guided her to lie down on the bed, smiling when Sam let out a groan.

"Why did you stop?" she whimpered, pressing herself against him.

"Because I want you to let go, Sam."

Sam sighed in frustration and grabbed his hard length, stroking it slowly while nibbling on the skin of his neck. "You're denying me an orgasm because you think you can make me let go?"

"Let me show you," he growled, pulling her mischievous hand away from his erection.

Then, he made love to her with patience and tenderness, as he rarely had in his life. He took the time to listen to every response from her body, every shiver, and every sigh she could let out. And above all, he tirelessly repeated those simple words to her.

"You only have to say the word, and I'll stop."

Sam felt like she was rediscovering her body. Sure, during their relationship, he had managed to turn off her brain in the sweetest of ways, but he had only turned off the thinking, not the autopilot she set in place whenever sex was involved.
That night, in the middle of Ireland, he truly showed her what it meant to let go. She felt safe in his arms and, for the first time in a very long time, allowed her body to dictate her reactions. So much so that the orgasm that overwhelmed her was so intense that she couldn't control herself and ended up melting into tears in his arms.

"Sorry. Sorry," she murmured, trying to hide her tears.

Jack smiled and kissed each of her tears, caressing her face with his fingertips. "Don't apologize, Sam," he whispered. "Never apologize for feeling things."

He slowly withdrew and immediately pulled her into his arms. Sam buried her head in his neck, as if she suddenly wanted to hide. The tears still hadn't stopped.

"You're wonderful," he murmured, his fingers tracing abstract symbols on the skin of her back.
He opened his mouth to speak again but swallowed his words at the last moment, holding back from telling her he loved her. It wasn't part of the deal; he wasn't allowed to say that.
