"That feels great," I said. "Be careful with your teeth. Yeah, good. Now take it a little deeper." I noticed that Emily had opened one eye to watch what was going on. "A little deeper. Nice. Nice..." Noelle was getting into a rhythm now and was taking more than half of my cock. Then she got a little too ambitious, gagged, and pulled back in surprise.
"You okay?"
"Yeah." She gave me a shy grin. "This is kind of hot."
"Yes, it is," I said. I put my hand on her head and guided her back onto my cock. She resumed sucking, and Emily was now watching my cock moving in and out of her sister's mouth just inches from her own face. I decided to give her a little more of a show. I pulled my cock from Noelle's mouth and gave her a few gentle slaps, leaving her cheek wet with her own saliva. Then I held my cock up and said, "Lick my balls." Noelle immediately complied, kissing them, then running her tongue over them.
"That is so gross," Emily said. When her twin ignored her and took one of my balls into her mouth, she added, "I can't believe you're doing that."
After another 30 seconds or so of ball-tonguing, Noelle looked up at me. "Am I doing it right?"
"You're doing great. Best first blowjob I've ever had."
She beamed. "Thanks. I like it."
"Of course you do," Emily said. "You've been dick-hungry since junior high."
"Well, then I'm glad to be the first to feed her one."
With that, Noelle wrapped her lips around my cock again and returned to her sucking, moving quickly and deeply down my shaft each time. The twins had separate necks, but they were so close that Emily's head couldn't help but move a little when Noelle's did.
"You're such a slut, Noelle. You've barely known this guy for a few weeks and now you're sucking his dick."
"Mmhmm," Noelle agreed around my cock.
"It's so gross. You've always wanted to be a whore, though, so you're probably proud of getting that big nasty thing in your mouth. I can't believe you. You're so cheap and disgusting. You—"
Without even thinking, I laid my right thumb on Emily's lips. Surprised, she fell silent. I let it move a little, lightly smearing her dark lipstick, and her lips parted slightly in a reflexive kiss. As they did, I pushed it into her mouth. Her eyes widened, but before she could react, I slowly drew it back out. Her mouth was opened in surprise now, so I pushed my thumb back in again. Her lips closed around it and for a second I worried about getting my thumb bitten off, but after a long moment she began to suck gently on it.
Here were these two cute girls in one body, kneeling in front of me, one sucking vigorously if inexpertly on my cock and the other tentatively on my thumb. I knew I couldn't last much longer. I put my left hand on Noelle's head and pushed myself in deeper and faster. She gagged a few times but gamely continued on. "I'm about to cum," I told her, "and you're going to swallow it."
Her "yes" was barely understandable with her mouth full of cock. I grunted when I started to cum and was ready to hold her head in place, but she didn't back away as I filled her little mouth with cum. My right thumb was still in Emily's mouth; she was swirling her tongue around it.
Noelle's eyes were watering when I finally removed my cock from her mouth and she swallowed the last of my load. I reluctantly removed my thumb from Emily's mouth; it came out with a wet pop. Noelle looked triumphant, Emily a bit dazed. I helped them to their feet, then grabbed their ass and pulled them close while I kissed Noelle.
"That was amazing," I said. I was overselling it a bit, but I wanted to give her confidence.
"Thanks. I'll get better, I'm sure."
"Well, my cock is available whenever you want to practice." I turned to Emily. "You should be proud. Your sister is a great little cocksucker."
"I'm not surprised," she said, and in addition to her usual sarcasm there was a note of jealousy.
About a week later Noelle invited me to their dorm. Their roommate was gone for the weekend, so they'd made me dinner, and we were enjoying some Netflix-and-chill on the couch. Before long the girls had climbed down onto the floor. I leaned back and spread my legs as they knelt in front of me. To my surprise, they worked together to pull my pants and underwear down and then pull out my cock.
"You have to admit, it is nice," Noelle said. She cupped my balls and gently started to stroke them.
"Yeah, it's okay, I guess." Despite her words, her hand started rubbing little circles around the head of my cock.
With both of them working on me, I started to respond quickly. Soon I was hard enough that both their hands were able to move to my shaft and begin to stroke me. It was a strange sensation; I was used to having two hands jerk me off, but these two weren't moving in complete unison. Strange, but nice. They were both staring at my cock in concentration. Noelle had copied her sister's cat's eye look, though as usual, Emily was a little more made up, with dark eye shadow and dark red lipstick. Her eyebrows were a little thicker than her twin's, I noticed, though they had the same long, thick eyelashes.
When Noelle's head moved forward to start sucking me, it was a somewhat awkward position, since Emily's head basically had to bob up and down, cockless, right next to hers. I could only see the tops of their heads now, but I heard Em's voice. "You're such a fucking slut, Noelle. If it were up to you, we'd probably be dropping to our knees ten times a day. I can't believe what a little whore you are." The sentiment was familiar, but the tone was breathless, almost excited.
I took ahold of Noelle's ponytail with my left hand, and she moaned as I began moving her head up and down my cock. "Don't you like your sister sucking my dick, Em?" Abruptly I pulled Noelle's head up and off my cock, now shiny with her saliva. I pulled it to the side, so that both their heads moved a bit to the left. "Maybe that's because you're jealous," I said, and, with my other hand, pushed Emily's head down.
The head of my cock pushed through her dark lips, and without hesitation she began to suck it. It was her first blowjob, but she had obviously learned a little from watching her sister's so close up. As Emily worked on it, Noelle was now treated to the sight of my cock moving in and out of a mouth inches from hers. And she was happy to tell her sister what she thought of it. "Ha ha, yeah, suck that cock, Em! You're always such an asshole. Such a prude little bitch, looking down your nose at everyone. Now you've finally got a cock in your mouth like you've always needed." She looked up at me. "You don't need to be so gentle, Paul. You can fuck that bitchy little face of hers."
I didn't need to be told twice. I held Emily's head still and slowly back to push my cock in and out of her mouth. Her eyes were closed in concentration, but she gamely took each thrust and even swirled her tongue around it each time it came out. When she gagged a few times, Noelle laughed. "Oh my god, you can't even take it half-way."
"Show her how," I told Noelle and slipped my cock back into her mouth.
This went on for about five glorious minutes. Because their faces were already cheek to cheek, it was the easiest thing in the world to move my cock back and forth between their mouths. When Noelle was sucking me, Emily went on about what a whore she was; when it was Emily's turn, her sister talked about how she was such a bitch. Noelle's hand was mostly on my leg and ass for support, while Em's slipped down beneath their legs.
Unfortunately, there was no way they could turn their heads enough to both work on my cock at the same time, but I had a thought. "I'm gonna try something," I announced, removing my cock from Emily's mouth with a pop. Their two little faces looked up at me, lipstick smudged, eyes wide. I carefully spat where their faces touched, then pushed my cock forward. Noelle moaned and Emily said, "Oh my god." Their wet cheeks were soft and warm on my cock, but there wasn't quite enough friction, so I put a hand to either side of their heads and pushed them together. Their cheeks now provided a little more resistance as I pushed my cock between them. It was like tit-fuck, except I was using two heads instead of tits.
Pretty soon I was close to cumming, and I had other plans, so I stopped and helped the girls to their feet. I kissed each of them, then led them into their bedroom, where I pulled the little blue baby-doll dress they were wearing up over their heads. "Take off your bra," I said as I kneeled and carefully pulled down their panties. When I looked up, the bra was gone, so I took their hands to help steady them as they stepped out of their underwear. "Lie down."
I don't know whether they had discussed this beforehand or if they just were both going with the moment, but they immediately climbed onto their bed. I stripped, then helped them scoot up until they were reclining, propped up on pillows. Then I moved down and gently parted their legs. From the waist down, they looked like almost any other girl: small, slightly rounded stomach; slender, smooth legs (shaving them must not be easy, I thought), a cute little pussy surrounded by a bit of well-groomed hair. I started with alternating kisses on their thighs. Noelle was already moaning softly, and by the time I got between their legs, Em was joining her. It didn't take much kissing and licking before they were wet. I explored with a single finger for a while—so tight!—then went back down to tease their clit with my mouth. Their hips began to buck, and before long their legs shuddered convulsively and they cried out as they came.
