The events of chapter 22 take place a few years following the events of chapter 21, with different characters, but still on the same colony.
Sharina had almost finished her wing of the dormitory. One boy was left. Well, two. One had put her off, even though he clearly had a raging morning erection. She patted him on the shoulder and told him she would coming back for him when he was "ready", but... would it would be worth it?
Clinton, on the other hand, was still sleeping. A darling, affectionate boy, he was unfortunately rather lazy. She patted his shoulder lightly (he was much more receptive) and, when he opened his eyes, whispered, "Good morning, Clinton, is there something you'd like to take care of first thing today?"
"Oh yes, ma'am, but before that, um -- "
"Yes dear, go visit the young men's lounge and when you come back, I'll be at the alcove." Waiting to take care of the SECOND thing he needed taking care of.
She thought how he would have difficulty peeing with a morning erection, always especially rigid in the dormitories because all the docents, though they wore chaste white "nurse" outfits, presented with the most stimulating demeanor: short skirts, tight tops, frequently bending over or climbing stepladders to reach high shelves. Sharina was especially proud of the way her nipples made distinct nubbly mounds as they strained against the fabric of her blouse. It seemed like she was forever sewing buttons back on.
Clinton came back promptly. He'd left his pyjamas on his bed, but wore his general-issue white terry bathrobe. The ones who were the most modest, Sharina thought as she closed the curtain to the alcove, were usually the most hot-blooded if they could find some privacy. Clinton was no exception. When he opened his robe she saw his erection was already straining out of his glossy black (trimmed to regulation length!) pubic hair. It stood at a boyishly high angle and looked her straight in the eye, swaying a little as he moved, the head swelling and darkening. Modest as always, he lay down quickly on the generously cushioned table, the robe covering his back, only his penis clearly visible, because it poked through the vent he'd carefully positioned his body over.
Sharina unclipped the sensor from the side of the table and waved it over Clinton's right forearm until its indicator lit green (no sense in distracting anyone with beeps and boops, much better to use quiet, warm little lights). The printer on the shelf behind her soundlessly disgorged a barcode label which she wrapped around a clear plastic jar. The boy was already pearling and she didn't want to take any chances, so she positioned it in the receptacle rack directly beneath his penis and clicked it in as quickly as she could.
Hurrying didn't work in this business, so she took a deep breath, slowed down, and cautiously snapped an "examination" glove on her right hand. It didn't tear, even though she kept her fingernails long (and used a muted brick red matte polish). Taking her seat at the tableside stool, she held her hand under the lubricant jet to get a few warm squirts from the heated nozzle in preparation for masturbating Clinton. To steady herself, and also because she enjoyed the feel of taut young buttocks, she put her free hand on his bottom and reached under to begin expertly stroking him, glancing under the table from time to time to make sure she was aiming him properly at the collection jar.
"Does this feel good, dear?" she asked softly. She knew it did, but she also knew it was important that he knew she cared about it.
