Fill the Void
Ivan could not stop the sounds that escaped him. Panting, moaning, sighing, the sounds he made came unbidden and involuntarily as Gilbert pounded deliciously into him.
"How do you feel, baby?" Gilbert breathed, his own voice hoarse with exertion.
"I... feel... good..."
He felt Gilbert's hands tighten their grip behind his knees. A cry ripped suddenly from his throat as a jolt of pure agonising pleasure raced up his spine. Gilbert had found that sweet, sweet spot inside of him, and he honed in on it with a determined intensity, his hips snapping rhythmically as each thrust delivered pleasure in unceasing waves.
"Does this feel good?" Gilbert chuckled. Ivan could only nod his assent, his voice lost.
The pressure to come was reaching a point. He wanted - no, needed - to come. His cock twitched where it lay hard and neglected between him and Gilbert, and he tried desperately to reach for it, but the bonds were too tight around his hands.
"Unghh... Gilbert... please... please...!" he pleaded, his bound hands straining above him.
"Yes, what is it? What do you want?"
"I want... I w-want..."
"Yes?"
There was light ringing laughter to Gilbert's voice as he teased him. Ivan loved the sound of it, it was a delightful sound.
"...touch me..." he breathed.
Gilbert obliged readily, his hand reaching down and wrapping around Ivan's cock, and Ivan let out a pleasured sob. He writhed underneath Gilbert who stroked him in short, jerky movements, the pad of his thumb sliding insistently over the frenulum. He felt the pressure building again, forming a knot just below his navel; he was so close...
"I'm... I'm com- I'm...!"
His release swallowed the rest of his words. His vision exploded into white as he came hard in Gilbert's hand. Hot ropes of semen spurted from his cock and landed across his chest and stomach. His leg, the one Gilbert wasn't holding, dug into the sheets, his toes curling.
When he came to, it was to the sound of Gilbert's laughter, a truly lovely sound.
"That feel good, baby?" Gilbert asked, smiling wolfishly.
"Y-yes," Ivan replied breathlessly.
If his hands weren't bound to the headboard right now, he would have reached out and grasped his beloved Gilbert by his face and kissed him, devoured him. As he was, he could only throw back his head and sigh.
"Happy birthday," Gilbert said suddenly, his tone uncharacteristically gentle.
Surprised, Ivan raised his head as Gilbert brought his lips to a pale white thigh and kissed it. Tears rose to prickle his eyes, but he blinked them back before Gilbert could see.
"I love you," he choked, the words coming straight from his heart.
It was Gilbert's turn to look up at him then with surprise. "Love you too," Gilbert returned, his smile softening.
Those words filled a little of the void Ivan carried in his heart.
