She leaves her shelter

Pfff. Alright, here goes nothing. Hannah double-checked that she was properly covered up before stepping weakly back into the party. She felt ridiculously exposed, her hard nipples rubbing tantalizingly against the rough fabric with every move. As she was moving through the crowd she got a lot of curious looks, and even in the dim light it was obvious she was blushing. She was moving past a group of boys when suddenly the vibrator turned on again. She nearly jumped in surprise and quickly moved on. Where were Alissa and Emma?! She recognized a lot of faces, but could not find the two of them. Fuck, she was so horny now, and the constant stimulation drove her wild. She would not last long. People were surely starting to notice too...

Finally, she spotted Alissa and Emma off to the side. Tbey were staring right at her, laughing between themselves. Blushing again, Hannah rushed over.

"There you are! Having fun?" Alissa smiled warmly.

"No! I came, can we go look for my key now?"

"No need! Someone posted about it in the groupchat so I picked it up for you."

She took the key from her pocket and dangled it in front of her.

"That does mean we have a little bit more time to play around. Let's have you cum just one more time." Emma teased.

"Fuck, ok sure! Where do I go?" Hannah relented. She just wanted to hold her key and flee home.

"Right here is fine. Nobody is paying attention to you." Emma answered, slowly turning up the vibration.

They were only just off to the side of the party, more or less in the open and not more than a few steps from the whole crowd of people. Hannah had brought some attention to herself by walking through the crowd, so she did not entirely believe nobody was paying attention to her. She moaned softly and nodded in agreement anyway. One last humiliating act.

Emma and Alissa continued to talk, only ocassionally involving Hannah with a question directed at her. Hannah felt so degraded by the way they ignored her, but it was probably better than the alternative. Still, she began wanting them to look at her. Slowly, she started to squirm a little, when Alissa suddenly asked her to open up her towel.

"Come on, just a little. Let us see."

Hannah looked around to see if nobody else would notice. She was honestly not sure. Even from behind it would look suspiciuous as hell. That said, she was not exactly thinking straight. She was so horny she barely cared about anything but climaxing again. Her legs were already quaking and bent at the knees as she unfolded the towel and spread it open like a set of wings, exposing her fully naked figure to the two girls. Alissa stretched her hand out and softly grazed her side. Hannah looked her straight in the eyes, her whole body trembling. She could not contain herself any longer. With the towel loosely draped over her shoulder she let go of one side and used her now free hand to rub her clit. It looked obvious to everyone around, even if Hannah thought she was being discreet.

She could feel the orgasm well up, and it washed over her with a sequence of powerful shudders, squirting all over herself with every convulsion. She felt the towel slip as soon as she began to cum, exposing her back and butt to the crowd. Only when she had finished did she quickly grab the towel again, but by then so many people had taken notice already.

"Ok can we go now?!" Hannah pleaded, suddenly so conscious of herself again.

"Easy, take a breath first."

"No come on we gotta go for real! People saw me!"

"Alright alright, let's go then."

Alissa took her hand. Hannah, still dressed in nothing but a towel, and Alissa started making their way back. Hannah was stared down by practically the whole party, but she was glad to be out of there. Still, she knew she would be confronted about this night at some point. How many people had seen her naked? How many had watched her cum? When they reached the end of the park and stood on the side of the road, Emma piped up.

"Actually, I might stay a little bit longer. Will you two be alright?"

"Yeah, sure no problem." Alissa responded.

"Ah, could I have that towel back before you go? I'll throw it in the wash."

Hannah was shocked. Were they really going to have her streak home? After all she'd already been through? Turns out, yes they were. Hannah had to slip out the towel and was left standing there totally naked. These girls had already seen her naked, but this time she felt even more ****. She was right out in the open. Emma took the towel and left them, and suddenly Hannah had nothing. She could hear people in the distance and she was well-lit in the street lights. She covered up her tits and cold, wet pussy with her hands and pleaded Alissa to hurry.

"You can run ahead if you like. Otherwise chill out and we'll walk together. Everyone is sleeping anyway, noone will see you."
