Now normally, when someone gives their respective boyfriend or girlfriend a gift, it's usually something along the lines of flowers, chocolates or something they desired to own for themselves. However, Sashi Kobayashi wasn't your typical girlfriend nor was Penn Zero your typical boyfriend for that matter. The two shared a very intimate and very…unique connection between them. While the two cared deeply for one another as most lovers did, they had a much more extreme way of expressing their love, and that included in the gifts they gave one another.

Such as the part-time hero finding a pair of his girlfriend's underwear in his locker.

"Sashi, a few questions" he began as the two lovers stood next to his locker in-between classes "One: why is there a pair of your underwear in my locker. And two: how did you even get into my locker?"

"I know your locker combination by heart" she answered off-handedly "and for my little gift, I thought you'd like it"

"It's certainly…something" was all Penn could say on the matter

The undergarments in question were a pair of black laced panties that felt a tad damp in the boy's hands. Despite keeping the underwear away from his face, he could still detect his lover's faint scent on them. Even though he knew this was the last place he wanted to have this gift out, he still couldn't help but feel turned on by this act of love on his girlfriend's behalf.

"What possessed you to even do this?" he questioned

"Well while I was in gym class, pummeling everyone in sight in a dodgeball match, I couldn't stop thinking about yesterday when you took off my garter belt with you teeth" Sashi explained

Ah yes, yesterday's lunchroom fiasco where his beloved mistress demanded he remove the present he had given her with only his mouth. During his removal of the garment, he left a trail of lust-filled kisses down her leg as a way of getting back at her for making him do this in public. Boone still wasn't talking them since then. At first glance, one wouldn't think that someone as carefree and easygoing as Penn Zero was secretly into these sort of expressions of passion, and truth be told he didn't he was either. It was thanks to Sashi that he found his love for latex, whips and handcuffs.

It was four weeks into their relationship when she first revealed to the part-time hero her secret obsession with all things that centered around BDSM. At first, Penn was taken aback by his lover's extreme taste in romance, but he didn't run from her and being the open-minded boy that he was, offered to give it a try. The second the blindfold was put over his eyes, the redhead was subject to a whole new world of pleasure through pain. Penn was surprised by how much he enjoyed being the submissive in the games they played, almost like he appreciated someone else taking the lead.

Despite what some books and movies would lead one to believe, this sort of sexual fantasy wasn't just to inflict harm one someone—though it had been twisted into that. In its purest of forms, it was the ultimate sign of trust between two people and there was no person Penn trusted more than the woman he loved. Since that first night, the two had become closer than they had ever been before, even if the outside world only saw a rage-filled girl smacking around her clearly whipped boyfriend—even though he did enjoy being whipped.

"All I could think about was your lips on my skin, your kisses all the way down to my feet" she continued, her voice becoming husky with lust as she thought back to that moment "Needless to say, it turned into Splash Mountain down there. I figured you deserved a present, so I decided to give you this as token my love"

"That's so gross but so hot" Penn said in amazement before noting something "So wait; these were the underwear you were wearing today?"

Sashi gave him a coy grin before nodding.

"So what are you wearing now?" he questioned further, even though he already suspected the answer

The part-time sidekick lifted her dress up slightly to reveal to her boyfriend a small part of her bare rear end.

"What the shit, Sashi?!" Penn nearly shouted before controlling his voice "are you going commando right now?!"

"So what if I am?" she replied slyly

"But what if someone sees your goods?" her lover argued

"If they were smart, they wouldn't even make eye contact with me" Sashi said with a pang of aggression in her words

That was true, the part-time sidekick's use of violence was known throughout the school. The slightest glance in her direction would be a death sentence for some. While Sashi was considered a borderline Yandere to the majority of the school at large, the part-time hero thought her violent tendencies were major turn-on for him, even before they started dating he found her aggression attractive.

"Look, if you don't want it, I'll take it back" his mistress told him, her voice with a hint of disappoint in her words as

She then reached out to take her underwear back; bur the part-time hero jerked his hand back.

"I never said I didn't like the gift" Penn informed her "I was just surprised you'd give this in the first place"

"I come from a culture that sells used panties out of vending machines and tentacle porn" Sashi causally replied "This is pretty tame"

"Well in any case, thank you" he said with a warm smile "…mistress"

Sashi grinned warmly before leaning upwards to kiss her lover deeply, to which he kissed back with just as great of passion.

"I gotta go" she said "I'll see you at Rippin's class"

"I look forward to cutting that class for some real art" the ginger answered "Maybe we can paint some nudes"

"That is no the way to your mistress, mutt" the part-time sidekick informed him "I'll have you to punish you for that"

"I look forward to it, my lady" her lover replied with a smile

Sashi rolled her eyes as she couldn't help but grin at that. With that, his mistress walked away, however, when she only a few feet away from, she stopped to give Penn a quick glimpse of her bare ass to him before continuing on to her class. The very sight of Sashi rear end was more than enough to make the part-time hero hard. So this was her punishment! He'd entire class unable relieve himself of this pain in his groin—oh she truly was evil!

Not wanting to be late for class himself, Penn took a quick whiff of his girlfriend underwear to keep himself sated for a short time until he could meet with his beloved once more. He then stuffed his gift into his pocket before rushing off to class, all the while thinking about all the ways Sashi was going to 'punish' him.
