Tap tap.

The MILF looked back to see who was tapping at her shoulder and interrupting her pleasure time. She was a perky and friendly looking young woman about Harry's age, with fair chestnut coloured hair tied in twin plaits that dangled before her shoulders, listening to music on her black earphones connected to the cellphone in her pocket. Her frame as well as her height concorded the harmlessness of her friendly smile, as she was half a head shorter than Harry and of a particularly petite built, yet not only was she the only one in the cart not ganging on the poor young man but had stepped right up to the feral women and looked the MILF right in the eyes.

"Sorry, I don't think this guy looks very comfortable with what you're doing. How about respecting his boundaries and take a step back, hm?" She asked casually and politely to the crowd of women holding Harry down.
The lot of them glared at her with indignation.

"Is it just me or did this cart get colder in here? Well, it's fine if you don't want to move. Come, let's go where there's just a little less crowd, shall we?" The young girl pushed off one of the women grabbing on to him and took him by his hand, leading him away from their grips and towards the part of the cart with less people.
She could feel his hand shaking.

"Hey! He's mine!" While the teenage girl's back was turned, the red-haired woman's closed fist swung at her in a wide arc.
At the last moment, the teenage girl dodged out of the way and faced the assailaint.

Harry could only look at this development in astonishment and terror. First the women were going to take his virginity, and now they were going to lynch the one woman in the cart still at her senses. Even though she just barely managed to evade what looked like a nasty punch she remained calm and composed, standing in the middle of the aisles of the cart with legs far apart and both arms extended with open hands, the right arm extending further than the left. It was an odd stance, more so with how relaxed and fluid it looked even though she didn't appear to move a muscle. It sure was pretty to behold and, Harry thought, it suited her well.

"Look look, guys! You don't wanna escalate this, all right?" The teenage girl said to the red haired woman in front of her, "If there's a misunderstanding somewhere I know we can just talk it..."
The red haired woman swung her fist at the heroine once again.
The teenage girl blocked it.
Or she punched her back.
Or both?
Is it possible to do both at once?
It must have been, because that's what happened. The red haired woman clasped her hands around her nose as she winced and moved back.
Harry himself winced as he saw the punch land "Oh crap! Oh hell! Is... is she all right?"

"Ah, you BITCH!" The red haired woman charged in at the much shorter girl, who once again dodged but this time by moving closer to her opponent; so close that her regular punches no longer were effective. The same problem evidently didn't apply to Harry's rescuer, since she managed to deliver a barrage of punches to the woman's chest, stomach and collar. Effective or ineffective Harry couldn't tell, but there were many of them, they were moviing at blinding speed and they were overwhelming. The red haired woman flailed her arms in desperation in an attempt to defend herself, but catching the fighter's fists was like trying to catch a fly with a lassoo.
The girl followed the red-haired woman's steps as she backed away and eventually fell to the floor, whereupon the girl with the headphones returned to the calm stance from before and shuffling back.
"Are we done now, ladies? He clearly isn't interested in your attention, I advice you back off."

Between Harry and the women who were going to use him, the woman in the headphones stood in the middle of the aisles. If they wanted to get to him, they were going to have to get past her first. But the aisles were narrow enough only to allow passage of at most three attackers at the same time. Three against one was quite the advantage for sure, but any one of the women weren't exactly looking forward to be one of those three, not with such a badass in the way. Especially not a badass who arose from such humble vessel.

But they could not let the object of their hunger get away so easy, not when they had the advantage of numbers. Soon enough three of them took their stance in the aisles, and rushed towards the girl in the earphones.
In response she backed away and stepped to the very end of the left of the aisles. The women followed her along, and ended up in que behind each other, allowing the girl with the earphones to deal with the attackers one by one.
The one in the front, a voluptous woman with shoulder-length hair dyed orange, attempted to kick the girl in the earphones. Before her leg could take off from the ground properly however, the girl in the earphones intercepted the kick and stomped it back to the ground, delivering consecutive punches until she fell down. She proceeded towards the women behind her, but they turned around and left before she could get the chance to strike them down.

The girl in the earphones presented her extended arm towards the women in the left side of the cart, then the right side. Each one flinched when she aimed her thin arms towards them, and no one else dared to advance.
With admiration Harry looked towards the woman who bravely defended him from being used, without him even have to ask, and felt warm and safe...
