As the party progressed, Alex found himself becoming increasingly aroused by the sight of Emily in her tight, black pantyhose. She was always so beautiful and alluring, but tonight there seemed to be something more brewing beneath the surface of her elegant attire. Her slender legs were wrapped snugly in the sheer material, accentuating their shape and contours perfectly. But it was the noticeable bulge at the apex of her thighs that really caught Alex's eye; it was unlike anything he'd ever seen before.
Growing bolder, he made his way over to her as she stood by the drinks table, chatting animatedly with a group of friends. He eventually worked up the courage to approach her from behind, wrapping his hands gently around her waist and leaning in close to whisper in her ear, "What's that bulge in your pantyhose, Emily? It's driving me wild."
She giggled softly, turning around to face him with a mischievous glint in her eye. "Oh, this?" She playfully circled her finger around the affected area, causing Alex's heart to race even faster. "It's just something I'm trying out for fun. You like it?"
"I do," he replied, his voice huskier than he intended. "In fact, it's driving me crazy."
Feeling emboldened by Emily's apparent enjoyment of the effect she was having on him, Alex pulled her closer and pressed his hardening cock against her rear end. To his surprise, she moaned softly into his ear. "Go on then, let me feel it," she purred, pressing herself back against him.
Without further hesitation, Alex slid his hand between Emily's legs and felt a wave of heat radiate from her pantyhose-clad crotch. She was already wet, and as he began to stroke her through the silky material, his cock twitched with anticipation. She let out a soft moan, and Alex could feel her body growing more responsive in his embrace. He couldn't believe what was happening; they were right in the middle of a crowded party full of their friends, but all he could think about was making love to Emily right there and then.
Suddenly, Emily stepped away from him, breaking their embrace. To his shock, she reached behind her and tugged at the waistband of her pantyhose, slowly inching them down her legs and revealing the source of the bulge - a massive, throbbing erection strapped to her thigh. It was like nothing he'd ever seen before; fully nine inches of throbbing, veiny cock, strapped to Emily's slender limb.
"It's a cock sheath," she explained breathlessly, her cheeks flushed with excitement. "I got it online - it sucks on my cock and makes it stay hard all night long."
Alex felt a mixture of shock and arousal wash over him. He couldn't believe Emily had been hiding such an enormous prick under her conservative outfit. "May I?" he asked, grabbing the shaft and giving it a gentle tug. Emily simply nodded, her eyes fixed on his as he began to stroke the shaft, milking it for all it was worth.
As he took in the sight of his best friend standing before him with a giant cock strapped to her leg, Alex felt a wave of lust overtake him. He couldn't believe she wanted him to fuck that enormous dick; it was everything he'd ever dreamed of and more. Without saying another word, he grabbed her by the hand and led her towards the bedroom. The moment the door clicked shut behind them, they were all over each other.
Alex kissed her passionately as Emily pulled off the tight pantyhose, revealing her smooth legs and eager cock. She lay down on the bed and spread her legs wide, beckoning him forward with her eyes. "Take it out of the sheath, baby," she whispered hoarsely.
Alex did as he was told, slowly unfastening the velcro holding the cock sheath together. It released with a wet pop, and for a moment, the enormous shaft sprang free before springing back to life again. It was even bigger now that it was free, pulsating and throbbing with need for release. Alex knelt between Emily's legs and wrapped his lips around the head of the cock, sucking it eagerly as he teased her smooth balls and perineum with his tongue.
Emily moaned loudly, her hands running through his hair as she took him deeper into her mouth. Her hips bucked against his face as he sucked harder, drawing out every last drop of pre-cum from that impossibly long shaft. Abruptly, she pulled away, pushing him onto the bed and straddling his waist.
"Fuck me with it," she begged, her voice thick with desire.
And so he did. With one swift motion, Alex thrust his hips upwards, burying his cock to the hilt in Emily's tight, warm pussy. She let out a scream of pleasure as he moved within her, their bodies connecting in a primal rhythm that seemed both familiar and yet entirely new. The head of his cock was hitting her g-spot with every thrust, sending waves of pleasure coursing through her body. She could feel the bulge in her pantyhose swelling even more now that Alex was fucking her so passionately.
He grabbed her hips tightly, pulling her down onto him as they fucked harder and faster. A load of hot cum exploded from his cock, painting Emily's insides as he emptied himself inside her. She grunted in satisfaction, her own orgasm washing over her as she finally released her cum onto his cock, gooey and warm.
Together, they collapsed onto the bed, panting heavily. Emily rolled off him, revealing the deflated but still imposing cock sheath strapped to her leg. "Was it everything you wanted?" she asked with a smirk.
Alex couldn't believe what he'd just experienced. Emily had literally been holding out on him this whole time. "More than anything," he replied, feeling his cock twitch again as he thought about all the dirty things they could do with that amazing contraption. Tonight was only the beginning.
