Mark walked down the boulevard, whistling, twirling a large knife between the fingers of his right hand. It was dusk, birds were singing in the park, a bus was pressing on the horn in some sort of traffic mix-up in the distance, and it was a good warm summer evening to be a serial killer.

The first girl to catch his eye was a dusky-skinned brunette carefully stepping over warm asphalt. She was clearly not used to going barefoot, which Mark found adorable. He stepped up to her, grabbed her hair, and drew the knife against her neck, then dropped her gurgling body and looked around.

There was visible movement around him as people noticed what he'd just done - some moving away from him, some closer. One girl walked towards him with her face in her phone, clearly unaware of what'd just happened. Well, no panties, no bra, no service, he chucked to himself and stepped up to her.

The girl had just enough time to look up from her phone as he roughly grabbed her, look ahead and have a look of realization on her face, when he rammed the knife into her pussy. She bent over, the arm he wasn't holding reflexively going to the wound, but she didn't really try to fight him off as he stabbed her above the first wound in the stomach, then again in the lung above her pretty petite breasts - he knew damn well where heart was, and this wasn't it.

He dropped her to lie gasping for air on the ground, and looked around again.

A cute redhead was looking at him curiously and rubbing her slit, but he ignored her. Instead his gaze settled on a little cutie, looking younger than most naked people here, blonde curls and an adorable turned-up nose, and the most enchanting expression of mixed fear and desire as she stopped to stare too.

He walked up to her, and she made a tiny step back, but did not try to run away or scramble for clothing from her bag. Her eyes were glued to his, face going on a journey of fear, resignation and excitement. So cute! He took her cute little hand and put the knife into her palm, then closed her fingers over it. Then moved her hand to beneath her pussy and lightly pressed, communicating his intentions.

She nodded jerkly and followed through, pressing on the knife until it entered the folds. He made a rocking motion with his fingers, eyes still glued to hers, and she complied, roughly jerking the knife back and forth inside herself. A whimper forced its way outside her puffy pink lips, and he could no longer control himself - he grabbed her and bit her lips, her mouth, her tongue, forcing himself onto her as his other hand took rough control of hers and savaged her pussy with the knife her hand was still on.

He turned her around, letting go of the knife, pulled down his own shorts - his erection, fully ready, sprang out proudly - and lowered her adorable round butt on it. Her right hand was still holding the knife inside herself - what a good girl, he felt a flood of warm affection - but the left dutifully reached around, spreading her ass for him to make the task easier. She gasped as he forced his way inside, cute little asshole clenching right on his dick - it almost hurt, but in a good way - and for a few minutes he was lost in the hot sexual haze.

Finally, he came, and after he was done pushed her off herself roughly. She could at this point no longer stand, and just fell on the ground in front of him. The knife came out - she was in no state to coordinate complex movements like that - and fell down.

He bent down to pick it up, and she wriggled on the ground like a worm to turn around and look him in the eyes again.

"Please finish me", she whispered, the first words she said in this entire encounter.

He wiped the knife on her cute little purse, then put his leg on her neck - and then his entire weight on it. She gasped, and her hands went for it - but she no longer had the strength to really resist.

He didn't bother snuffing her properly, waiting another minute or two after she passed out. He just wanted her to stop bugging him, so he took his sandal off her throat as soon as she went properly limp, and moved on down the street, looking around.

There were noticably fewer naked girls around him - so so many suddenly and unexpectedly sprouted a scarf or a light t-shirt or a skirt, what a surprise - but the few who still were, were giving him bedroom eyes still… and he was still in just the right mood to indulge.
