Panties - Spock
He came back from helping Scotty repair the casing around that leaking junction down in the most inaccessible Jeffries tube on the entire ship. He was coated with coolant, lubricant, and sealant. He stripped, dropping his clothing in the laundry container in the corner of the closet, and headed into the bathroom.
Half an hour later, he came back out, finally feeling clean. Nyota would not be off duty for another hour. He padded out to the comlink, still nude, and checked for messages. And then he went back into the bedroom to see whether she had left him a note there. No note. However, there on the floor by the foot of the bed, half hidden by the corner of the spread, was something bright red. He bent down and picked it up. A pair of her silk and lace panties - the ones she had been wearing yesterday, to be exact. He held the fabric to his nose and inhaled, pulling her scent deep into his olfactory glands.
She had climaxed at least once before he had removed this garment. Her scent clung to the fabric like heavy perfume, and his body responded, his lok beginning to harden. He suppressed the reaction. It was too long until she arrived. He rubbed the silken fabric between his fingers and the receptors in his fingertips tingled and throbbed. Possessed by a sudden compulsion he did not entirely understand, his hand dropped and he rubbed his semi-erect lok with the fabric. Intense pleasure throbbed throughout his body. This was a new sensation, not something he had experienced before.
He experimented, trying to find a way to surround his lok with the fabric with no wrinkles in it to distract him from the sensations he was generating as he rubbed the fabric against his body. After several unsuccessful attempts, it occurred to him that wearing the garment in question might work. Carefully he stepped into the lacy red panties and pulled them up, checking as he went to be sure that they were going to fit. He did not want to damage them.
When the panties were in place, he began to rub against his lok from the outside, and then he began to walk about the room, still stroking, the movement of the fabric against his lok causing paroxysms of pleasure. It was on his third circuit of the room, his lok fully engorged now, that Nyota entered the bedroom. She stopped in shock at the sight of him. "Spock? What the heck are you doing?"
He stood stock still, his hand on his lok. His ears and cheekbones turned a dark green. No sound came out of his mouth.
Nyota walked in a circle around him, looking him up and down. "Good look on you. You planning to do that often?"
He could still not think of a single thing to say. His lok throbbed in his hand. He opened his mouth, but still nothing came out.
She advanced on him then, standing so close that her belly almost touched his hand. "Can two play at this game? Or do I just have to watch?"
"Two, please." Finally, words. A wicked smiled creased her face and her cool hands descended to replace his frozen one. He moaned at her as she moved the silk across his sensitized skin.
"Feels good, doesn't it?"
He could only groan in his growing excitement, as she circled her hands around his hardness, wrapping him in the soft fabric. And then, suddenly, her hands were gone and he gasped. But she was only pulling her uniform over her head, tossing her underwear after it, and then she was pulling him to the bed. He only had time to realize that she still had her boots on before she descended on him again, tormenting him with delicious friction until he roared at her and lifted her above him. Her hands freed him from his silken prison only seconds before he pulled her down, thrusting hard up into her warm center. She wailed at him as he pounded into her, overcome with desire. He kept his hands on her hips, steadying her, as she leaned forward and held onto his shoulders, rocking her body against his. It took very little time at all until she screamed and clenched her interior muscles about him, so hard and tight that he roared at her and blasted his release into her, flooding her with his hot semen.
When it was possible to think again, she looked at him in wonder. "All that from wearing my panties? I guess I need to buy you some silk boxers."
He could not help but agree with her.
