Troy closed the door behind them gently.
"So what did you –" Calsu pushed him over onto the bed before he could finish. She grinned and straddled his waist, her armour gone somehow. She must be fast at undressing, Troy concluded. All she was wearing was that tight black skinsuit. "Uh... Calsu?" Troy wondered if this was another one of those things she did unintentionally.
"What is wrong Troy?" she purred seductively. "I will not bite... hard." She winked at him, and there was no mistaking what she wanted to do with him now.
"Al-already?" he stammered. "B-but we j-just –" Calsu put a finger to his lips.
"Shhhhh. I am not one of your kind, remember? When a Sangheili wants someone, they have to give themselves to that person first." She leaned in close so she could whisper in his ear. "I am giving myself to you." Troy started to panic. What was he supposed to do? He loved Calsu but had so many doubts.
"C-Calsu, what if I'm... I'm small by Sangheili standards? What if we don't even have compatible sex organs? Jesus Christ, I'm a virgin!" Calsu jerked up, losing some of her arousal. He had a point.
"Do you have a penis?" she asked bluntly. Troy nodded nervously. Calsu relaxed a bit, regaining some of those hormones. "Good, that is all I need to hear. We can work this out... together." She stroked his cheek gently. "We will never know if we do not give it a try." Troy submitted. He hoped he would be good enough for her. He knew the basics of sex from school, but that didn't do anything to help his stamina. She slipped easily out of her skinsuit like a snake would shed its skin, leaving Troy dumbstruck on the bed. He gawped at her perfect curves and smooth, reptilian skin. Troy quickly glanced away from her wet vagina. He felt himself go hard. "Surely you know that we have to be naked to do this?" Troy blushed as he realised he was still wearing his clothes, and that Calsu was staring at him expectantly. Troy clumsily took his uniform off, and soon he was naked and tomato red in the face in front of his Sangheili friend. He refused to meet her eye out of embarrassment, awaiting her reaction to his body.
Calsu's face turned purple slightly. She was blushing. Troy was aroused by her too? That was something she found extremely relieving. She then noted the expression on Troy's face and quickly closed the gap between them. She pulled him in close and kissed the nape of his neck, eliciting a gasp of surprise and pleasure from her partner. She had mated once before with another Sangheili, and it was nothing like this. This human actually cared about her, was actually pleased with her, and was making her very emotional – the predominant one being happiness. She pulled back slightly, only enough so that she could align her mandibles with Troy's lips and kiss him. Troy was quite limp in her arms, shaking slightly from the pleasure. Calsu found the opportunity to slip her tongue into his mouth, increasing the passion of the kiss. Troy's eyes drifted shut and he wrapped his arms around her waist, accepting the presence of her slender tongue in his mouth.
Troy moaned as Calsu started to trace intricate patterns on his back softly with her fingers. As she pulled away, a single strand of saliva connected them. Calsu giggled as Troy blushed again. She pushed him flat on his back and stared hungrily at his stiff shaft. She gave it an experimental stroke, making Troy buck his hips. She grinned wickedly as she proceeded to pump it, making him gasp and shudder in pleasure. Though soon she felt him grab her wrist. She stopped and looked at him, slightly confused.
"Y-you've g-g-got b-better st-st-stamina than m-me," he warned her. She nodded. He was only human after all. She wondered how he was going to compensate when he grabbed her rump and guided her so that her dripping wet sex was hanging above his head. She was completely and utterly confused now. Her kind don't care about mutual pleasure, it was the males who mattered. So the last thing she expected, because she couldn't peer over her shoulder properly, was for Troy to lick her most sensitive place. She gasped and collapsed onto Troy's lap, taken completely off-guard by the sudden pleasure. She moaned softly as Troy started to eat her out, feeling like a queen. She closed her eyes and enjoyed the intense feelings coming from her nethers, almost allowing Troy to bring her to an orgasm before she forced herself to stop him. She panted for a bit before finally managing to communicate what she wanted through hand gestures, too flustered to speak. Troy nodded, getting up on his knees and watching her stand up on all fours. She glanced back over her shoulder and signalled him to start. Troy pushed his dick into her slowly, relishing the feeling of her tight vaginal walls. Calsu gasped in rapture. How much further did he have to go? She felt a little bit of pain as he kept pushing in, but refused to cry out. Eventually, he bottomed out inside her. He let them both adjust to the new feeling before slowly withdrawing, then spearing forth again. He repeated this several times, eventually getting into a rhythm of thrusting. Calsu gasped, panted and moaned only slightly more than he did. He grabbed her ass for support and started thrusting deeper and harder. Calsu couldn't hold herself up anymore, so she collapsed again and let Troy hold her rear end up as he continued thrusting. However, before he could bring both of them to climax, he started slowing down. Calsu could easily hear his heavy breathing and new her mate was too tired to keep up his movements.
Calsu gently pulled away from him, making him completely unsheathe himself from her depths. He groaned slightly in protest, but was too exhausted to make any physical retaliation. Calsu pushed him onto his back again and held herself above him. He stared at her through half-lidded eyes, not fully comprehending what was about to happen. Calsu let gravity pull her rump down upon Troy's waiting shaft, enveloping him in her once again. Troy bucked slightly, then just lay there and moaned as she rode him mercilessly, bringing them ever closer to their release. Troy started bucking up into her again when the feeling got extremely intense, and they soon fell into a rhythm; as he thrusted up, she would fall down, meeting in the middle and slamming their pelvises together. Calsu knew she was about to scream as her climax hit her, so she leaned down and kissed Troy again, letting her tongue droop into his mouth tiredly. Troy clasped her tightly as he came in her, and she came around him. Calsu went limp on top of her mate, breathing heavily. Troy's eyes drifted shut, and before Calsu joined him in sleep, she managed to pull the sheets up over them.
