Mira smirked as she placed her latest purchase into her handbag and walked out of the shop. She'd been looking for months for the perfect way pay back Kieran for being such a thoughtless jerk; he wouldn't soon forget another birthday after she was done with him. Now that she'd found the perfect way she just needed a few more items to pull off the plan, this was going to be a fun day shopping.
Several hours later Mira stood at the sink in the bathroom of the small flat she shared with her boyfriend; with slightly shaky hands she opened the small kit she'd purchased earlier. Inside was a tube of "personal lubricant" and a small plastic cup; the kind you'd find at a sperm bank. She opened the medicine cabinet, where she knew Kieran kept his bottle of lube. After emptying his bottle into the sink, Kiera poured the lube from her own tube into the bottle.
Next, she put on the red and black bra and panty combo she'd bought earlier that day, hoping to look as sexy as possible for Kieran. Satisfied her preparations were complete, Mira bounded over to the bedroom, lube and cup in hand, where he was waiting.
"You finished prettying yourself up for me?" he said as his girlfriend entered the room. Kieran himself was completely naked and lying on their bed as she slowly approached him. She'd withheld sex from him ever since her last birthday had slipped his mind and the extended dry spell had left him particularly ready to make the most of the opportunity, now that she had apparently forgiven him as his rock hard cock could attest.
"Sure did" Mira replied with a wink. "How would you like me to take care of that for you" she said pointing to her boyfriend's erection and holding up the bottle of lube.
Kieran couldn't believe his luck; he normally had to wait for special occasions to get a handjob; before he could give an enthusiastic reply Mira was on him. The feeling of rubbing her lube-coated hands on her boyfriends cock was amazing; she normally got no pleasure from giving him this little present but the excitement for what was about to happen was intoxicating. Pleasure surged through her arms as she got faster and faster until she could feel he was about to blow. Quickly, she took the plastic cup and placed it right in front of his tip. Kieran as he grunted and his load shot right into the cup. The semen was glowing a light blue color, something Kiera had never seen before. She put the lid on it, as it was extremely important that was kept safe.
"Wow, that was great" Kieran said panting as he recovered. Mira grinned as she knew what was about to come next. Kieran's eyes flew open in surprise as his entire body began to quiver. Pleasure like he'd never felt before was surging through his entire body. He moaned loudly, going uninterrupted for over half a minute. Then, the pleasure grew too powerful, and he blacked out.
Mira could hardly contain her excitement. The process was underway.
