Please finish me

"I think calming down will be difficult.... but cumming would help" Sarah uttered, still aroused and anxious at the thought of cumming in front of a stranger. By now her cock had finally grown to it's full size, twitching and leaking as Sarah was shifting around on the sofa. Lucy got up. "Please excuse me for a second, I just need to get something. Be right back!" Wondering what Lucy could need to get, Sarah tried to relax on the sofa for a moment. The leather felt soft on her bare skin, but she noticed a couple of stains all around the fabric. It seems she wasn't the first person to get excited while trying on some fetish gear. Lucy came back, smile as before, with a big bucket in her hand. Sarah could guess were this was going. It was widely known that futas came more than men, and after revealing her interest in orgasm denial to Lucy, the assistant probably assumed her client had a bit stored up in those heavy balls.

Without another word, Lucy placed the bucket on the ground and immediately got to work on Sarah's engorged member. Using the plentiful stream of precum, she started stroking first with one, but soon with both hands, to try and cover as much skin as possible. Not knowing how to react, Sarah just sat back and closed her eyes, letting the experienced brunette do her job. It was obvious that she had done this many times before, judging by the rhythm and care with which she caressed the twitching fuckstick. "Don't worry, just relax." Lucy's soothing voice and steady stroking made Sarah feel comfortable and her nervosity faded quickly. "Focus on my hands, do you like this speed? I could also use my mouth, if you agreed to it." Sarah opened her eyes again and watched Lucy's careful movements. The assistant was clearly enjoying her work. 'I bet most of the guys she helps out don't even come close to my size' Sarah chuckled to herself. "I would love to feel your mouth" she moaned, almost out of breath from all the blood streaming into her erect cock.

The brunette saw her opportunity and took it. Soon her beautiful red lips had wrapped around Sarah's shaft as the girl swallowed it easily, almost down to the base. Sarah was surprised, but assumed the assistant got a lot of chances to train in this type of job. The pleasure from Lucy's tongue combined with her lips gliding along the massive erection was unlike any other blowjob Sarah had gotten before. Her balls were tightening now, and the blonde girl could feel the upcoming orgasm. "I-i am going to cum now, ok?" she stuttered. Before she knew it Lucy had already pulled her cock out of her mouth again and with one smooth motion pointed it right at the bucket beneath Sarah's feet. Sarah's balls began to pump as she filled the bucket with sticky hot cum. Lucy only licked her lips at the sight, but as a professional, she couldn't just go and drink futa cum on the clock.

Soon the bucket was full and Sarah's once swollen balls entirely empty. Between all of the seed streaming out of her dick and the heavy breathing and moaning, Sarah hadn't even noticed Lucy grabbing the most suitable looking chastity cage from the couch and quickly locking Sarah's now much smaller and softer cock inside. "There we go, fits like a charm! Are you satisfied with this model?" Sarah needed a moment to gather her thoughts again. Realizing the situation her penis was now in, blood quickly streamed back into it, but unsurprisingly, she couldn't get boner again. The pink plastic of the cage held tight around her meat and so all she could do was watch her veins fill and her balls jiggle. Sarah smiled to herself. She already loved this feeling. Now she just had to get her denial streak back, that she just wasted with the cute girl in front of her.

"I like it! I will take it", Sarah exclaimed, satisfied with the results of the fitting. Lucy smiled again. "Great! Please follow me back out to the counter and then you can pay. Since all of the sizes cost the same, you don't even need to take it off for scanning."

As Sarah was leaving the store, she realized what she had just done. The thought of wearing a cage under her panties aroused her more than she expected at first, but she was very satisfied with her purchase. Maybe she would visit the store again in the future, just to see Lucy and maybe give her a second chance with her cock. The day was still long however, and for now Sarah was already thinking about what to do next.
