Sperm Donation with Nicola SeXStoRY

Nicola had a young builder guy working on her house. She admired his physique through the window appreciatively. She took him a cup of tea. "Thank you Ma'am." he said. That's good Nicola thought, a young man with some respect. She brushed against him and ferltg him tense up. That's good too she thought, he's interested. She touched his upper arm, her delicate slim perfectly manicured fingers spanning his bulging bicep. "My," she purred at him, "you are a well developed lad, aren't you?" He blushed but did not pull away. "How old are you Craig?" she questioned. "Just eighteen Ma'am, last week Ma'am" Craig stuttered out. "Oh good," Nicola breathed in his ear, "you're a full grown man then. Just right for me. Would you let me masturbate you?" The directness of Nicolas approach startled him. He'd not expected that! But Nicola had learned that it did no good to hint around what she wanted, the direct request worked best. The upshot was that Craig found himself standing naked in Nicolas kitchen while she perched demurely on a stool beside him. She busied herself wiping his naked shaft with an antiseptic wipe, cleaning the skin and wiping the crest of his swollen glans. Needless to say, Craig was fully erect. "You have nice fat balls Craig," she complimented him. "Excuse me Ma'am, but what are you going to do to me?" he asked her. "Why, I am going to extract your sperm young man. What did you think? I will make you spurt off in a moment and I'll collect your offering to keep." Nicola mastrubated him gently, noting his degree of stiffness and the strain of his neck and leg muscles. She paused and picked up a small glass vial which she'd placed handily. She wrote "Craig's Sperm" and the Date and Time of extraction on its label and brought it up to his swollen glans close. Her fingers rippled expertly and she noted his state of arousal. With a few more tweaks, she brought him to orgasm. Powerfully, his thick spurts jetted into the glass vial and Nicola caught them expertly. She watched fascinated. Eleven heavy spurts happened as he emptied his balls for her. "Thank you Craig," she told him, as she capped the vial and quickly popped it in her deep freeze. As the door opened, she checked the sight of the array of other vials, each containing a charge of frozen seem, and each with a different man's name written on the label.
