“I’m bored,” you laughed as San complained to you, needy for attention. Eager to give it to him, you raised your eyebrows.
“What do you want to do, then?” you asked with a little smile. San’s face flushed quickly as several ideas came to his mind, none of which he was bold enough to say to you. While the two of you had done some pretty filthy things, he still hadn’t gained the courage to initiate things or ask when he needed it.
“Let’s go swimming,” he prompted you, tugging slightly at your arm and hoping to distract himself from the less innocent things he wanted to do.
You smiled subtly as an idea came to your mind, but you didn’t say anything about it. “Sure, baby boy,” you nodded, “That sounds fun to me.” You stood up and walked to the cabinet to get some towels, with San following closely behind you.
“Okay,” he said, a hint of surprise in his voice as if he hadn’t been expecting you to say yes, “I’ll get my bathing suit.”
“Don’t bother,” you remarked casually, “You won’t need it.”
Confusion and irritation flashed across San’s face as he opened his mouth to protest, “But-” you cut off his indignant question by sweeping out of the room, sliding out the glass door that lead to your back patio. San followed behind you like a puppy, still desperate for your attention, more confused protests on the tip of his tongue.
“Have you ever been skinny dipping before?” you asked him, tilting your head. Immediately, San’s face turned bright red as he shook his head quickly. You smiled at how innocent he looked. “It’s easy,” you slid your hands across his shoulders and began to unbutton his shirt, causing his breath to hitch in his throat.
Once his shirt was in a little pool around his feet, you walked away, sliding your own shirt over your head and letting it fall to the ground. You heard San swallow audibly at the sight of your bare back as you unclasped your bra and let it fall, too. Your shorts were next, falling to the ground, closely followed by your panties, until you were completely naked.
You slid into the pool, sighing at the warm water, and didn’t look back at San until after you were almost totally submerged. He still stood as still as a statue, his eyes the size of saucers and his adam’s apple bobbing as he swallowed nervously.
“Come on, Sannie,” you urged him, “Don’t be shy.”
San seemed to gather some courage from your words, letting his shorts fall to the ground. Finally, after several moments of nervous hesitation, he slid out of his boxers, leaving his perfect body bare for you to skim with your eyes.
He slid into the pool, approaching your nervously as he likely knew where this would lead. You pulled him closer to you gently, a groan escaping his mouth as your chest pressed against him. You could already feel San hardening beneath you, his eyes pleading and helpless.
“It’s okay, baby,” you threaded your fingers through his hair gently and pulled his face down to yours, letting your lips meet his. San sighed into the kiss, grateful for the attention and release he would evidently be getting from you. You slid your tongue against his bottom lip, and he eagerly granted you access to his mouth.
As you kissed him, you let your hand wander down to grasp his shaft, which was now rock hard. San whimpered into your mouth, and you hushed him gently. “Don’t worry,” you assured him, “I’m gonna make you feel good, okay?”
San nodded slightly, trusting you, and you revelled at how perfectly obedient and helpless he was in your arms. You tightened your grip on his shaft, pumping him up and down gently, and he whined quietly. Your thumb came to circle his head, and he moaned despite himself. You could see his face turning bright red, but you ignored it to recapture his lips with yours.
“Wanna feel you,” San groaned, “W-wanna be inside you.”
Surprised that he would ask you so forthright, you pulled back a little bit to kiss his ear gently. “Yeah, baby?” you asked, “You wanna cum inside me tonight?”
San nodded his head jerkily, and you laughed at how desperately eager he was for you. You released his shaft, prompting a low whine from him. With his hand in yours, you guided him to touch your entrance and clit, which was already throbbing for him.
Already knowing exactly what to do, San began to trace figure eights on your core mercilessly, getting you ready for him. It would be plenty wet since you were in a pool, but your baby boy couldn’t miss a chance to make you feel good. You moaned quietly into your shoulder as San’s fingers circled your clit.
“Are you ready, love?” you took his hand away before it got too far, and he nodded quickly. You grabbed his shaft again, ready to guide him into you, but San stopped you gently.
“C-can I hold you?” San asked. You smiled slightly at how bold he was being tonight. It was different from how he usually was, and you liked it. All you wanted was to take care of him, and it was much easier when he could tell you what he needed.
“Are you sure you wanna pick me up?” you raised an eyebrow. San nodded, his adam’s apple bobbing, and he hoisted you up gently by your thighs as if to prove he could do it. You smiled at him gently, tracing the muscles that rippled along his arms. San’s shy and obedient personality made it easy to forget how strong he really was.
“You like it better this way, baby?” you asked, your lips ghosting across his ear as you reached down to stroke his shaft again slowly. His head fell back and a low groan escaped his throat as he nodded.
“Y-yes,” San stuttered, “W-wanna feel your body against me.”
Your breath caught in your throat as you guided his tip into you, letting him fill you up inch by inch. San made a whiny noise in the back of his throat, his chest rising and falling rapidly with how good it felt. Your let San rest his head against your chest, moaning softly into your skin while you tugged against his hair gently.
San began to thrust into you, slowly at first, but gaining speed as you urged him on. You bounced up and down as he pounded into you, your nails digging into his back to keep yourself steady. You felt San tighten his grip on your thighs as if he was afraid his legs would give out, and you wouldn’t be surprised if they did.
The two of you moaned out loudly in unison as he hit your g spot with a particularly harsh thrust, causing you to clench around him uncontrollably as the knot of pleasure in your stomach tightened.
“P-please don’t clench around me like that,” he whimpered, “It feels s-so g-good and I don’t want to c-cum yet.”
You gave his hair a sharp tug as you snapped your hips against him again, “Don’t worry, baby,” you said, your voice breaking and trembling with the moans that threatened to escape your throat, “You’re being such a good boy for me.”
You felt San throbbing inside you from the praise, his thrusts starting to speed up again and brush against your most sensitive spot over and over again. Your moans grew louder and louder with each passing moment, and San whined uncontrollably into your neck as he was pushed closer and closer to the edge.
“F-fuck!” he cried out, “P-please ‘m gonna c-cum.”
“Go ahead, baby,” you moaned into his ear, holding him closer to you, “You can cum.”
San let out a strangled whimper at your permission, snapping his hips up into you quickly. It didn’t take long for you to let out a moan that bordered on a scream as your orgasm washed over you, your legs shaking as San held you up. His whiny moans intensified as he began to shake too, before you finally felt him release inside you.
You gently pulled yourself off of San’s cock as you both came down from your highs, but San insisted on keeping you in his arms as he tried to catch his breath. He buried his head into your neck, kissing you gently, and you rested your head in his hair.
“You were such a good boy for me,” you assured him in a whisper, “You did so good, baby.”
San sighed contentedly at your praise, and you let him hold you until he caught his breath.
