18F, shoplifting. Guard to me, jail, or I fuck you

I had shoplifted and got caught. The guard was a fat old bald guy who stank of sweat. I was in a back room at the mall, his guard room. "take your clothes off" he demanded. "NO" I told him. Fine, then I'll have them bring a woman police officer to strip search you when they arrest you. I begged him not to call. My dad made me bend over the arm of a chair last time and he hit my bottom 20 times with his belt. My mom finally made him stop. I was so embarrassed, my jeans were at my ankles, my panties he pulled down to my ankles. He had seen my grown pussy and ass. I couldn't do that again. The guard told me we could arrange something. I asked and he said if I stripped and let him touch me all over he may let it go. Hesitantly I stripped, after talking some more about it. My B cups were sticking out in front of him, my hairy pussy, my ass, I was totally naked. Now this stupid old guy was feeling and squeezing my boobs. Then he was pinching my nipples till they hurt. "OW, stop that, it hurts" then the slob started sucking on them. As he was doing that he mumbled about how pretty I was and how firm my boobs were. His hand went down to my crotch. I wouldn't spread my legs I knew he wanted to stick a finger in me, but I was a virgin and didn't want this troll doing anything to spoil that. "Spread your legs" he demanded. "I can't, you can't put fingers in me, I'm a virgin, I don't want that".

"Well, honey how about I just call the police?"
"I can't, I'm a virgin, please don't make me, don't do that to me"
"OK, but I'm going to have to do something."
"I'll suck you" I told him. I'd sucked two guys at school several times before.
"Suck to get hard, then I want to fuck"
"I can't I told you, I'm a virgin, I don't want to spoil that"

He reached down and grabbed my butt. "You a virgin here too?" he asked. "YES, of course" I answered not quite sure. "Then I'll fuck you in your cute, tight ass". "NO, that would hurt, please don't hurt me" I begged
He pulled out his cock it was small and thin. "It won't hurt I promise, it's not that big see? You suck me hard, then I fuck you in your ass. No one can tell if you've been buttfucked, you can tell as many guys as you want you have a virgin butt, no one can tell" he said.

Standing there naked, his mouth on my boob, his hand separating the cheeks of my butt. "No, I can't do it" I told him. "then that isn't a problem, get dressed, and I'll put the cuffs on you till the police arrive" he said pulling off my butt and my boob. "No, please not the police, my dad will beat me naked again please don't" I begged as I was pulling his mouth to my boob again. Sucking he mumbled, "so it's jail and beating, maybe more jailtime, OR I fuck you. Your tight virgin ass is good enough for me".

He brought out some lotion, as I got down on my knees and sucked his little cock till it was hard, he must have been leaking in my mouth, I could taste this weird, slimey taste to his sperm. I was kinda hoping that he'd blow in my mouth. Then he pulled out, bent me over the desk, and lubed us both up. It didn't hurt really he was only about 5 inches long, but not thick at all, not even an inch thick I think. It only took him about 5 minutes to shoot his sperm up my butt. He handed me some tissues as he sat down. I wiped up, and put my clothes on. At the door I opened it, him still with his pants down sitting in his chair, and held up the tissue. "This is DNA evidence that you raped my ass, if you ever try this shit again with anyone, I'll go to the police". He turned pale white as I left. I left the door open.
