High gas prices, no problem! SeXStoRY

Im a girl, but I also have a twin b*****r, Ted, but I always call him teddy, its just one of his buttons I like to push. He didn't get his drivers license until way after I did, mostly because we did a lot of stuff together so I drove him everywhere. Like any teenagers we had no jobs, rarely any money, but wanted to go everywhere. We were on our way to a party, and were still a while from getting there, but the tank was empty. I pulled into a gas station, realizing we were 15 minute drive from home or the party, with no money on either of us, and no gas. Our parents were out of town, we were home alone, so they couldn't bring us money, so after 5 minutes I came up with a plan. I took off my panties, hiked my skirt up showing half my ass, took off my bra, and unbuttoned my shirt to where only one button was holding it closed. I told my b*****r to start filling it up when I gave a thumbs up, and started twards the cute geeky guy at the register. I walked in and told him our situation, he felt sorry but stressed he couldnt give away gas. I asked if he had any money on him while twisting the button on my shirt. He said yeah but none he could afford to spend. I chatted with him until the customer in there left, then I walked behind the counter. He asked what I was doing, and I started rubbing under his shirt, and asked again if he could help us out, he said maybe a discount, nothing else though. I begged a little more and ducked under the counter when another customer came in. While he was servicing them, I pulled his pants down and let him pitch a tent in his call of duty boxers. I took off my shirt and laid it in the floor, and pulled my skrit up around my belly. When the customer left, I pulled down his neat boxers. I licked some precum off of the tip of his very stiff cock, and asked if this will get me half a tank. He broke and said "I guess so, but no more!" So I began sucking, making sure I didnt make this guy cum before getting a full tank from him. I stopped sucking and put my butt in the air, and rubbed my pussy against his shaft, and asked "will my pussy get a full tank from you?" He said "fine, but the condoms are on the other side of the store, and I am not going to get them." I stood up and said alright, and walked first to the front door, gave my b*****r the thumbs up, and he laughed, then pumped the gas, and I went and grabbed a condom. I used my mouth to put on his condom, then bent over under the desk and let him start at my pussy. I think he may have been a virgin, he was having a hard time getting it in my pussy, he tried to thrust it in, and it slipped into my ass. I yelped "thats my ass!" He apologized and pulled it out quickly, I just said "no boy that is fine, happens a lot actually, just take off the condom, and you can fuck my ass all you want, even blow your load in my ass. He quickly pulled off his condom, and stuck it back in. I asked if he was a virgin, and he said yes. I said, well start just thrusting boy, I want your cum in me. He grabbed my hips and started pounding my ass, I even let out a couple moans. The bell in the shop went off in the store, and the boy said "may I help you sir?" and the voice of my b*****r said "no im jsut waiting on my s****r to finish up." The boy was still thrusting in and out of me while chatting with him while he just walked in and grabbed a couple drinks for us and said "I think my s****r has these taken car of, am I right?" I yelled "almost done b*o" and the boy said "yeah they are on me I guess." I told him to lay on the ground, and he did. I sat on his cock, and worked my ass on his cock, squeezing, going up and down, back and fourth, twisting, so he came soon, filling my ass. I got up and told him I would always "buy" my gas here, and left to the party with my b*****r.
