One day, while listening to our local rock station, I heard about a concert happening in Denver, and a bus was available for people that wanted to party on the way there.  I quickly called and got tickets for my girlfriend and I.  It was a couple of weeks away, but the bus sold out the first day.  We were so excited to go that the days took forever to pass.  Finally, the day arrived, when the bus picked us up, we got a seat half way back on the left side.  Although it was a party bus, it was definitely bring-your-own-booze.  Curiously enough, though, the bus actually stopped at a liquor store not far down the road.  We all bailed out and hit the liquor store.  While in there, my girlfriend was in an aisle across the store, and as I walked towards her, I could see that many of the men from the bus were checking her out!  Long blonde hair, in a french braid.  She was tall and a little too skinny, lol.  She had no tits at all, and was braless in a t-shirt, and wore tiny shorts, that couldn't come close to covering her ass cheeks.  The holes ripped in her shorts verified that she wasn't wearing any panties, either.  I spent more in the liquor store than I did on the bus tickets and concert, but I wanted my girlfriend to be pretty well smashed for the rest of the ride, which was several more hours long.  Back in the bus, we drank lots of grape vodka, Baileys Irish Cream, and various other fruity and coffee liquors.  I was careful not to swallow when she would see me take a drink.  An hour later, she was flirting with everyone on the bus - just what I was hoping for!  Although my fantasy would have been for her to get gang-banged on the bus on the way to our hotel, it didn't happen.  However, she did let me rip a few new or bigger holes in those tight shorts, and she let one of the guys from the bus cut a v-neck opening in her t-shirt down the front, as his friends cheered him on.  We all chanted "lower" "lower" as he ripped it down the front, below the level of her nipples.  She let me open the front a few times enough to show off her nipples to her new fan club, and then we got to our motel for check-in.  We already had room assignments.  The fancy motel, was anything but, and all of the rooms were on the ground level.  Our room was right in the middle, where two wings of rooms met, and everybody walked past our room to get to theirs.  We had about two hours before the concert.  We dropped our bags on the floor, and didn't even bother to shut the blinds or our room door, which was open about six inches.  It was a sweltering hot July day, so it felt good to have everything open.  She was horny, and we left our clothes on the floor, too, as we started fucking on the bed.  I made her sit on top, reverse cowgirl, so that anyone walking by would see her facing them, her flat tits on display as she rode me.  Many people and couples stopped to watch for a minute or even a few minutes.  None felt brave enough to join us though!  After our show, we crashed on the bed, and slept in the nude for probably an hour and a half.  Then we showered at got ready for the concert.  We all boarded the bus that evening, and nobody commented.  Everyone was very tipsy and joyful!  The concert was good and loud!  As my girlfriend and I danced the night away, many men would approach us and ask to dance with her!  I was delighted!  It was so very dark where we were, that the men were not afraid to fondle or finger her there.  Her blouse was unbuttoned all the way, and she was nude under her skirt.  At least four guys took turns fucking her as they swayed to the music in the dark.  The next morning, she had hickies on her breasts, from the guys sucking on her breasts and nipples.  As it turned out, most of the men weren't from the bus, but that didn't matter.  The next day, on the ride home, a young guy approached us and asked if my girlfriend could come to the back of the bus for "a little while".  "Of course," I blurted out.  I stuck my tongue out at my girfriend and gave her a little push toward the aisle.  The music was really loud in the bus, but I smiled as I looked back at her.  She was holding onto the seat back as she rode on their cocks, bouncing up and down, each guy's bareback cock cumming deep inside her.  I lost track, but I think nearly every guy on the bus took a turn in the back and blew their loads in her cunt.  After the first couple of guys, I noticed that she didn't have her shirt on any more.  I guess the bus driver didn't care, if he could even see that far back!  When we got home, each guy gave me a "high-five" as they left the bus.  I couldn't wait until we got home, so I ate her pussy in the car, as soon as the bus left.  She had pretty well lost her cum loads in the bus seat, but her pussy was super hot and totally soaked.  I ate her for a couple of orgasms, enjoying the taste of all that stranger cum!
