When Rina was several blocks from the bus stop she was seeking, something changed. She didn't know it at first, but the water from the ice was completely gone, and the first drops of the oil were escaping from the bottle. With its higher viscosity, the oil acted differently from the water, when it touched the fibers of her shirt. With a wicking action, it found its way along the threads, spreading in all directions, slowly. That means it went horizontally, in addition to vertically. She felt the wetness moving from the center of her chest, climbing the inner slopes of her tits. Not only that - the oil was much more efficient at rendering the fabric transparent, and making it cling to her skin!
As she looked down, she saw the pinkness of the curve of her breast appearing! She tried walking a little faster, but was still afraid about the possibility of tripping. The change in appearance of her shirt was drawing more attention from the passersby. Dave, who was behind Rina, saw the people coming toward him looking more sharply at her, and displaying expressions of surprise now. Ignoring her, he walked quickly by, and got far enough ahead to turn back for a look. The edges of her areolae were just starting to be revealed by the oil!
Rina glanced down, shocked that most of her nipples were showing now. At moments like this, it wasn't unusual for her to almost curse at herself, "You fool! What have you gotten yourself into this time? You don't want to walk through town with your tits exposed! Why did you do this to yourself?" But she could do nothing to prevent it - she was being forced to do it - by herself! She realized that in planning a self bondage session, she was taking the part of her own Mistress. And when executing it, her role changed to that of the submissive, deriving pleasure from being obedient and pleasing her Mistress. She felt mortified and humiliated, but with her wrists cuffed, there was nothing she could do about what was happening. And that very helplessness - being forced to be on display before all these strangers was such a turn on that her heart raced, her tummy fluttered, and her cunt muscles started churning, pushing out the juices formed by her erotic lubrication.
Dave stayed ahead of Rina, snapping pictures now and then, until one of her tits was showing her full areola and nipple, and the other was half revealed. It was obvious even from his distance that Rina was turned on by this ordeal. Her nipples poked forward as hard little mounds, and her tits were heaving as she panted, trying to maintain the aeration of her blood to match her racing pulse. He stepped aside, pretending interest in a shop window, and let her pass. He wanted to record the reactions of people now as they noticed all of her tits on display through her shirt. He knew that being hyperalert, those same people might notice him taking pictures, so he dropped farther and farther back, using the excellent zoom powers of his camera.
The people walking toward Rina were now displaying mainly shock, followed by nudging a friend and whispering. If they weren't registering disgust at her public display, the women often smiled and the men often leered. But they left her alone, sometimes turning to look back at her as they continued on their way. She was torn between the embarrassment of being trapped like this, and the excitement of being so lewd in public. She was certain that if someone happened to rub a hand across her pussy when she was in this state, she'd cum instantly!
Her walk almost over, Rina focused on the bus stop, rather than the people, and saw the bus coming around the corner, and stopping to take on passengers. Her heart went into her throat. If she missed this bus, she'd have to wait an hour for the next one! She began hurrying, heart racing and breathing ragged. Her tits were wobbling all over the place with her rapid progress, and the T-shirt material clung to them almost like a clear, glistening plastic wrap. She reached the bus doors just as the driver was about to close them and cried out, "Wait! Please!"
He did wait, letting her stumble aboard, closed the door, and started driving. That's when Rina realized her cell phone was in the side pocket of her skirt, and her cuffed hands couldn't reach it! How was she going to pay? Thinking fast, she grabbed her skirt and twisted it on her hips, bringing the pocket within reach. She pried the phone out of her pocket, and activated it to the payment app. Meanwhile, the bus driver had stopped at a light, and swiveled his head to see why the scanner hadn't beeped, signaling her payment. His jaw dropped as he stared at her two breasts, now fully revealed in their glistening sheen of oil.
Rina angled her body to bring the phone to the scanner, heard the beep, and hustled back to claim a seat. She took the one right behind the rear bus exit, and sat, panting with relief at accomplishing this huge milestone. "I made it!" she thought. "And I'm heading home, finally." Her relief was short-lived, though because... Dave hadn't made it to her bus! He'd been too far behind, taking pictures, when she'd bolted to climb aboard it. Now he'd have to wait another hour for the next one. She truly was completely on her own now - handcuffed, oil still spreading across and down her front, rendering her virtually topless. She whimpered softly, but also squeezed and rubbed her thighs together, teasing her clit.
One young man had noticed her as she walked down the bus aisle, and he was pointing her out to his friends. They were all laughing and making comments to one another that she couldn't hear, but her ears turned red with shame. The trouble was, that shame was being transformed into even more arousal, and she was startled at how strong the smell of her cunt juices had become as her lubrication increased.
It didn't help her situation any as she remembered how, when she was cuffed over the railing in the meadow, she'd begged Dave to let his friends Lou and Cliff fuck her like that. She imagined what it would be like if those young men on this bus came back to where she was and bent her over a seat back. They might flip up her skirt and find she wasn't even wearing panties. Helpless as she was, she'd not be able to stop them from each fucking her, using her as a fucktoy, and dumping their loads into her cunt or ass.
Subconsciously, since her hands were in her lap under the sweater, she started pressing her fingers through her skirt, rubbing her intimate valley. The bus route back toward her home took a lot longer, since it traveled along a completely different path. She had time to work herself into a minor sexual frenzy, but didn't dare bring herself to orgasm - afraid she'd be so vocal that she'd be made to leave the bus. She just simmered and stewed.
As people got off at their stops, they walked right up to her, before descending the rear steps to depart. Some inhaled, wondering what the strange scent was in the air there. Rina was ogled. She was berated. She was called many different derogatory names, mostly by old people, who found her display obscene. As they departed the bus, some muttered words that she was shameless and told her to cover herself. But she couldn't, of course. Ultimately, she moved far to the rear of the bus. As she changed seats, she couldn't help but notice that she'd left a wet spot on the seat!
The raucous young men got off at the next stop, but not before making loud, rude comments about her tit display. The oil had now covered her entire front, and she was pressing her hands against it above her waistband, trying to prevent it from soiling her skirt, as well. For the remainder of the ride, enough people shot penetrating looks at her that her mind was whirling with embarrassment, blended with arousal at being bound as she was. She was positive that the back of her skirt must be soaked with her cunt juices.
As her bus stop approached, she had to press the signal for the driver with her shoulder. When she got up from her seat, scooting into the aisle, the movement fanned the fluids on the back of her skirt. She departed the bus, leaving behind the aroma of aroused female in a cloud that wafted into lots of nostrils. Some people were confused at what they were scenting, but most of them were appreciative, especially when they clearly saw her perky nipples bobbing and weaving under the transparency of her T-shirt as she started walking away on the sidewalk.
Rina hurried home as quickly as she dared. Her eyes were darting all over the place, praying she wouldn't encounter any of her neighbors. Not only would they see her virtually topless - suppose one of them offer his hand for a handshake, or something. What could she do? Her hands were cuffed to her belt, and Dave wouldn't be with her for another hour or so.
She didn't see anyone she knew. But lots of strangers stared at her curiously. She almost sagged with relief when she reached her house. Keeping her balance, she climbed up the steps to the side door. She and Dave had a special place of concealment for a spare house key there. Unfortunately, since her hands were smeared with the oil, the key slipped from her fingers, bounced once, and fell off the side of the steps into the bushes!
