A bold run just like he is now

K-T was feeling weirder and weirder, he really needed to go ask his sister what was going on and fast. The issue was that he had to pull his shoes on and especially without wearing socks, he'd need both hands to do so. Hands that were currently busy hiding his crotch and that something was missing there. He wasn't sure what was more embarrassing, girls seeing him down there or seeing he had nothing there now.

While the lady was busy sorting some assortment of lacy panties (and not bothering to put on any underwear) he grabbed his shoes and tried to put them on as fast as he could, but not fast enough. The lady turned back, probably after getting a glimpse of him in the reflection of the washing machine's door.

"Ohh I see, is that one of those high tech sex toys those geniuses are inventing these days? I understand why you don't mind being naked like that. After all you have nothing to hide so you don't really need clothes." She said in a way that was absolutely not judgmental. She seemed to be encouraging him.

K-T had not yet decided if he would dare ask her for clothes, but after a remark like that he was pretty sure that she would not lend some to him. Not to be mean, but because she looked convinced that he didn't need to wear any.

As for sneaking home it wasn't really an option. The way home was nearly a straight line in a residential suburb with barely any cars street parked; he would have nowhere to hide.

Lily was already up and seemed eager to go.

"Come on K-T. It's not a big deal. This thing covers you almost as much as some of the swimsuits I've seen you wear. You know what, we run home! We'll be back in almost half the time it took us to get here and if you hold all the way there you'll get a reward." She announced cheerily. It was clear now that she was definitely flirting with him and trying to imagine what the reward would be filled him with courage and energy.

He had been **** to streak before, it wasn't new to him even if he didn't like it. He simply followed Lily outside and went on with it. He had learned that trying to cover made him slower and actually attracted people's attention, so he stopped bothering and focused on following Lily, at least this time he didn't have to worry about his dick flopping between his legs.

The promise of a reward from her gave him wings. He was in the zone, only focused on keeping on with her, he tried his best to ignore the whistle of people who were in their front yards, the honks of a few cars and even the group of girls who started filming when he passed them on the sidewalk.

His legs hurt, his lungs were on fire, his mouth dry… he had to continue. The only other thing he could feel was this constant tingling in his junk and the occasional poke or jolt delivered to it. He couldn't explain it but something felt wrong and without being able to see his dick or get an explanation he had no way of knowing what it was.

After a few eternities, only made shorter by the sight of Lily's bouncing but in her tight spandex shorts, he finally reached his home.

He was almost safe but stopped in the pathway to catch his breath before reaching the front door. The last part of the run had been hell. He had slowed down a lot because he couldn't hold the pace and painful electric shocks like the one that made him cum earlier happened more times than he could count, but not with the same effects after he emptied his balls so recently.

"You did it! I'm so proud of you!" cheered Lily, grabbing him in a hug and kissing him on the cheek. He was in heaven and hadn't dreamed of something like that happening with her on their first date. Her tits were pressed against him and he could feel the warmth of her body, with him naked and her wearing so little most of the points of contact were naked skin on both sides. He noticed that she had gone so far as grabbing his butt while hugging him. "are you Ok? You seemed to struggle a lot by the end of it."

"I'm fine, it's just… I think something is wrong with the device and it was pretty painful." he explained. Still, that reward was worth the painful exertion to him. He walked to the door and opened it (his sister had set some sort of biometric camera to unlock it automatically to authorized people) only to see Lily follow him and even pass him on.

"Let's go see your sister about that thing, I'll also ask her to give you time so we can train together." She told him.

"Give me a second I'll grab something to wear."

"Don't be silly, if that thing is hurting you we have to see your sister right away. Besides, she'll probably make you strip to examine it." She retorted. And as much as he hated it he had to admit that she was right. "Then once we're done with that I'll give you your reward."

One could have picked K-T's jaw on the floor, the awesome moment they just had was just a spontaneous show of affection and not the reward she had planned for him.

Full of hope and really excited he followed her upstairs to his sister's lab. He doubted his dick would be able to go soft at any point today with everything that was going on , but he had to figure out what was happening to him.
