I got [F]ingered by a random on the bus to my Halloween party.

I live a fair way out of the inner city and was invited to a friends Halloween party in there in one of those connected old school townhouse things that all face the street. I hadn't been out for a while so I was pretty keen.

I've been in a slutty mood lately so I wanted to dress slutty. I went with a Roman gladiator which essentially had me in a skirt thing that came just to the bottom of my ass cheeks and a corset style "leather breast plate" that just had my tits out everywhere. It was perfect, but in no way historically accurate. With a G-string underneath of course.

I had to catch the bus in and was looking at about an hour long ride. I had 3 friends heading in with me too. We must have timed peak hour to perfection because the bus was packed.

We're all standing about half way down trying to talk when we make a stop. Some shuffle off and some more shuffle on and I get brushed and a little "polite" but obviously unnecessary touching as some young group of guys moves past.

As I'm shifted around I feel another hand touch my thigh about halfway up. It lingers for a bit too long to be one of the young guys and I freak out momentarily and freeze before it goes. I decide to ignore it. At the next stop it happens again as someone moves past me. This time a touch higher up my thigh and the hand gives a slight squeeze.

It was at the moment of the squeeze that my brain realised this wasn't just an accident. Or an opportunist having a grope. my whole body comes alive and is ultra alert and of course, I get instantly wet. My internal dialogue is basically just "omg is this a actually happening". I realised that I wanted it to happen. So badly I wanted it.

I flicked a switch and focused back on my friends. Rejoining the conversation while also subtly arching my back and shoving my ass back towards where I thought the hand was coming from. I got a few light touches for my trouble light enough that I wasn't sure if it was my groper or not.

At the next stop that had people getting on and moving past he came back. The hand was put on my inner thigh about half way and slid up a fraction. My pulse raced immediately and I made sure to open my legs a little and lean back into it slightly. I wanted him to know what he had found.

He seemed to get the message because this time the hand stayed and when I realised I had him my pussy was legit quivering like a horny schoolgirl.

For the next ten minutes he squeezed and stroked my inner thigh, slowly working his way up and under my skirt. Teasing the shit out of me and driving me crazy.

He first started brushing my pussy through my panties and I had opened my legs as much as possible and arched my ass back at him so much anymore and I would have looked ridiculous.

He started exploring the edge of my panties before lifting them a little and moving them to the side exposing my soaking wet pussy. As soon as his finger slid along my slit and found my slutty hole he slipped it straight in.

I nearly had an aneurysm trying not to moan right in the faces of my friends who had no idea. Well maybe one of my girlfriends was getting a bit suspect that something was going on but she probably thought I was wearing a toy or something so all I got was a sly look before she turned her attention back to the conversation.

He slid another finger in within about 30 secs of the first and I was starting to get seriously close to just turning around and sucking whoever's dick was within range I was that horny now.

I realised we were only a few minutes from our destination so I started using the natural rocking of the bus to let me move back and forward instead of fighting it and this kind of let me fuck his two fingers to an extent but only when the bus moved.

A min into this and my friend mentioned our stop was coming up. He must have heard because I was rewarded with a third finger instantly. At the same moment the bus hit a particularly shitty piece of road which to my delight had us all rocking around back and forth and allowed me to fuck his hand while he fucked me while everyone else was focused on not falling over.

I was close to cumming hard when he started using my own juices, which must have been all over his hand, and his thumb to rub my asshole. He started pushing his thumb up my ass while he had three fingers in me and it pushed me right over the edge.

I had to rapidly pick my handbag up to my face as if I was digging into it to find something while I came hard all over this strangers hand. As I lowered it two of my friends are in active conversation and my girl friend from before is giving me that look again haha. The hand slipped away.

Two minutes later we're off at our stop and walking to the house party. I never looked up at the bus as it drove on.
