It was Friday again, and I was sitting in the empty lecture hall grading papers. I knew the spot where I had fucked Miss Browning last week and Laura had dripped my cum and hers' onto the floor. Not even a stain. Good cleaning staff we have around here I guess. What were the chances she'd show up again and I could fuck her brains out two fridays in a row? Slim and none. She got her grade changed after all, and I got a nice piece of ass. Those blue eyes smiling up at me as I pumped her throat, and a spray of thick cum into her dark brown hair. Definitely one for my journal all right.

The door opened. Probably the janitor. Nope, it was someone I didn't recognize. A young lady in jeans and a T-shirt. Not one of my students, in fact no one I'd seen before. Nice small set of tits, and those jeans were tight and worn low on the hips. I could see a navel piercing as the bottom of her T-shirt swayed back and forth. What a dirty old man I am. I hadn't even looked at her face other than to see if she was someone I recognized. She was cute. Not gorgeous, but cute. Short brown hair, big brown eyes. She was walking toward me slowly, carefully. I got the feeling she felt awkward and out of place.

"Are you the Professor?" she asked me, still 15 feet away.

"Yes, I am," I responded as professionally as I could, "how may I help you?" I was thinking she was going to enroll for next semester.

"I'm Lindsey-Laura's sister."

It didn't register with me, and she saw that. "Laura Browning's sister, Lindsey."

Well now, this was awkward for me. What did this girl know, and what was this going to be?

I hadn't had much time to consider the questions when I saw Laura enter the lecture hall and bar the door. So much for "slim and none" I thought.

Laura Browning was wearing a yellow sun dress and sandals, and she came down the aisle with a definite "come and fuck me" walk.

"We have a proposition for you" she said.

Laughing I said "Well then proposition me Miss Browning!"

"She's a senior and still a virgin," she said, indicating her sister Lindsey. "Just 'cuz she's got a piercing doesn't mean she's been pierced, if you know what I mean?"

I looked at Lindsey and she was blushing, turning red.

"Did you know that your sister was going to do this?" I asked the young lady. Lindsey nodded, averting her eyes.

"She heard me talk about it-I mean I wasn't talking about it! I wouldn't want you to get fired or anything. I mean I was telling her how good it feels," Laura explained. "She'd like to have the feeling."

"Okay, if that's what you want-it is what you want isn't it Lindsey?"

"Yeah, I think so," she said.

"And what about you Miss Browning?" I asked Laura. "Are you back for some more cock? Because you were a pretty good little screw last week y'know?"

"My cunt's out of action this week-I'm on the rag-but I'd like to swallow a load again!"

"Why don't you girls let me clean up this paperwork and then come over to my house or something? That'd be a little more comfortable for everyone."

"Okay, we'll just wait in the hall for you," Laura said.

"Hold on a minute" I said. "Lindsey come here for a second." She walked up to me, a curious look on her face.

I reached out and pulled her to me, kissing her lips. She opened her mouth and our tongues mingled in one another's mouths. I felt her hand on my hip and guided it to the bulge in my pants. "You're getting hard!" she said, pulling out of the kiss. Her fingers closed around the bulge, she squeezed my cock gently. "Want to see what I'm gonna pop your cherry with?"

"Uh-huh-"

I whispered "unzip me Lindsey."

With trembling hands she worked my zipper down, then parted the waistband of my underpants and my cock burst out. She ran her fingernails along the shaft.

"Does that feel good Professor?"

"Yes it does, but you know what feels even better?"

"If I lick and suck you off-"

"That's right," I said, putting my cock back into my pants and zipping up. "Something for us to look forward to, okay?"

"Yeah, okay" she said, kissing me before joining her sister at the back.

As I cleaned up my papers and put them in the briefcase I thought that perhaps it was not a great idea to take these sisters to my house. I might say that I don't give a shit what the neighbors think, but in truth I do care a little bit. I remembered that motel on the edge of town that I had met the married woman at last year, and I gave Laura and Lindsey directions to meet me there. I had half a fear they'd stand me up, but then I recalled the look on Laura Browning's face when I fucked her into ecstasy last week. They'd be there all right.

I couldn't get the end room this time. I had to settle for Room 7 instead. Maybe we could compensate by getting some combination of events that would total at least 7. Two blowjobs and five orgasms? Three orgasms for each of them and one monster cumshot from me?

They pulled up in a nondescript sedan just as I was unlocking Room 7. They both looked around to make sure no one saw them, then they scurried into the room. It was sexy to see these two young, fresh girls hustling in to have some of my cock.

There was an awkward moment. What to do, where to start? I took Laura Browning by the hand, sat down in the chair next to the bed with her on my lap. I kissed her gently and felt her mouth open and her tongue dart aggressively into my mouth. Her hands rubbed my chest. I stroked her nipples between my thumb and forefinger, and she moaned. I felt her hand on my cock. I was creating the right mood all right.

"Do you want me to go down on you?" she whispered.

"What do you think?" I said, running my hand up her skirt and finding her panties soaked from her flowing cunt.

"I think you want me down on my knees being skullfucked," she giggled, climbing down between my legs and unzipping my pants. Laura didn't hesitate but took the length of my shaft into her mouth and throat. When she had plunged me deep inside her oral cavity two or three times she took my cock from her mouth, strands of saliva connecting her lips to my throbbing cock. "Does that feel alright Professor?"

"It would feel even better if someone else was learning how to give head," I said. "C'mere Lindsey," and I took her by the hand, as her older sister massaged my balls, and pulled her beside me. I slipped the teen's T-shirt off of her, revealing a pink bra, her little breasts just cupped in it. I could see the brown of her nipples showing. She leaned over and I tasted her tits. I rolled her nipples in my fingers, and pulled her bra down. She reached around and unsnapped her bra and it fell. I threw it on the floor out of the way. "No what?" Lindsey moaned. I unbuttoned her pants. "I'm getting into your pants baby." "Okay," she whispered. "I want you to get into my pants.

"Tell her what happens then Miss Browning."

Laura licked the length of my cock, coating it with her spit, and kissing it up and down. "I'm getting him really hard so that he can ram this huge cock up inside of you Sis. You've never felt anything this good!I know if I wasn't on my period right now I'd be on this cock rocking his load up inside of me."

"Will it hurt Professor, when you burst my cherry?"

"It'll feel so good a second later that you'll forget why you wanted to be a virgin so long."

I pulled her jeans down and found the pink bikini panties that matched the bra. They were beginning to get wet in the crotch. "Give me a minute with her, will you Laura?"

Miss Browning hopped up and went into the bathroom to clean up a little.

I laid Lindsey on the bed and pulled her panties off, throwing them to the floor with her bra. I spread her legs and rubbed the brown fur above her pussy. I leaned over her and tasted the brown fur. It was sweet, slightly perfumed. While I kissed her breasts and rubbed her fur, I slipped a finger in her cunt and stroked her clit with my thumb. "Ooooh-oooohh-yeah! I like that-oooh."

"You liked being finger-fucked do you," I said, nibbling on a spot below her left ear.

"A lot-I like being finger-fucked a lot I just found out!" she said, beginning to grind her hips. I got her nice and wet with my finger fucking, and then I went down and licked her tender pink cunt for a few moments. Lindsey moaned loadly.

"Can I come out now," her sister asked.

"Yeah, we're about to progress to the next lesson."

As Laura walked out I placed Lindsey on her knees at the side of the bed. She grasped my cock and started to stroke. "Did you say you'd rather have a blowjob than a handjob?" the teen asked, smiling up at me.

"Put my cock in your mouth Baby" I whispered. "It might be too big."

"No it isn't," her sister said, joining her on her knees in front of me. "Watch me little sister."

Laura proceeded to take me deep throat, my balls up against her nose. "Now start slow, take it easy, but take him into your mouth," she told her sister.

I watched as Lindsey licked the tip of my cock slowly, tentatively.

"Look in my eyes as you lick and suck my cock" I told her.

She stared into my eyes as her mouth slid over my cock, slowly taking it into her oral spaces, inch by inch until all 10 inches were inside. My cock was throbbing inside that warm and moist cave. She stopped when her nose was up against my balls, and I felt her tongue probing my shaft. I closed my eyes and thought I was feeling paradise. Lindsey slowly, very slowly backed my cock out of her mouth, and Laura showed her how to play the skin flute. I let the musicians play for a few moments and then decided it was time to fuck Lindsey's teenage cunt, and maybe her tight ass too?

I helped her onto the bed, she stroked and played with my cock as I tongued her pussy. She was wet, she was ripe. "Spread your legs and open your cunt," her sister instructed her.

The head of my penis gently pushed aside the pink and wet lips of her vulva, like a visitor to a foreign land moving ahead carefully until faced with an obstacle. A wall. I drew back and used my cock as a battering ram to bust through her hymen forcefully! Lindsey squealed and grimaced. I stopped for a moment, my cock about 75 buried inside of her. Then, as the grimace was replaced by a smile, I fucked her pussy hard and deep. She climaxed fast. Well she was a rookie. A tight, tight, sweet-cunt rookie. When she caught her breath I put her on her knees on the bed and fucked her cunt from behind. She came again, pretty fast. "How many times are you gonna fuck me?" she asked. "Three."

I stood her up against the wall and pounded her cunt, lifting her to tiptoes with every thrust. She lasted longer but came and almost fainted. I still had a load working in my balls and it was time to do something about that.

Lindsey laid on the bed and recovered while I put her big sister on her knees in front of me. I stood and got ready to discharge my load in a face-fuck of Miss Browning. "Put it everywhere," she grunted as she swallowed my manhood.

"Do you like the taste of my cock?" I asked.

"Mmm-hmmm-uh-huh" she moaned, licking every inch and gurgling her spit with my pre-cum.

I cupped my hands behind her head and forced her face up and down on my swollen cock. Laura Browning knows how to give head, how to coax a load of fresh hot pudding from a cock. I felt my balls sending a massive shipment, and so did Laura. Her eyes grew wide and a smile surrounded my pulsating cock. She swallowed the first shot without spilling a drop, gulping it down. Lindsey hopped down off the bed and knelt beside her as the second shot coated her face. Kid sister licked drops of cum off Laura's nose. "That doesn't taste too bad" the teenager said. I fired the third shot into her mouth, and Lindsey licked her lips with a cum tongue.

The girls didn't have to be anywhere for awhile, and since I'd paid for the room, we curled up on the bed and took a nap together. After 45 minutes I felt like I might be able to go again and started messing with them. They responded beautifully. Laura informed me that she couldn't screw because of her period. That wasn't what I wanted anyway. I bent her over a chair and went up her ass with an enthusiastic cock. Five minutes of banging brought on her climax. Then, just because I could, I fucked her little sister's tight, tight virgin ass too.

When they left in their sedan Laura was panting and Lindsey was walking bowlegged from the fucking she received.
