"Thanks for picking us up, Uncle Frank!" piped Sissy, as they pulled into her uncle's driveway.

"No problem, sweetie, I haven't seen you and your brother in a while, we can watch a movie or play a game, if you'd like."

"Oh! I'm sorry, Uncle Frank, but Scott and I need to talk to Anne-Marie, it's... it's private!" Sissy felt guilty about excluding her uncle, and wondered what he'd think if he knew what they were going to do. "Umm, maybe... maybe we can do something together next time," she said, and gave him a kiss on the cheek.

"My, that was sweet, darling. You're going to be a little heartbreaker when you grow up!" He chuckled, and added with a wink, "Anyway, I know all about mysterious childhood secrets that seem SOO important at the time. You two go talk with Anne-Marie, I won't bother you."

"Thanks, Uncle Frank," said Scott, although Sissy could tell that her brother was nervous. "I... I wish we could play a video game today, but..." he shrugged, as they climbed the porch steps.

"Hi, Sissy, Scott!" their pretty cousin said, giving each of them a big hug. When she hugged Scott, Sissy saw Anne-Marie glance down at his crotch, and Sissy giggled to herself when she saw that her brother already had a boner. "Sissy told me a little about... your problem... on the phone, so Daddy, I want you to PROMISE to ignore anything you hear from my room, OK?" With that, she hugged her father, and Sissy was amazed as she watched the older girl grind her body against that of her father for a moment.

"Ohh... OK, sweetheart. I promise!" Her uncle crossed his heart, and Sissy snuck a peek at his crotch. She wasn't really surprised to see he had a boner just like Scott, and she gave her cousin a thoughtful look.

As they trooped back to Anne-Marie's bedroom, Sissy pulled her cousin aside. Making sure that Scott couldn't hear, she whispered, "Anne-Marie, do... do you and your daddy... umm, do sexy stuff?" Her cousin shot her a shocked look, although Sissy could see that the girl was blushing. Anne-Marie looked ahead at Scott, then nodded quickly. "Don't worry, I won't tell. Uncle Frank is really nice! Maybe... maybe someday, he'd... umm, never mind."

Anne-Marie looked at her and winked, then said, "OK, guys, here we are!" She turned to shut the door, and continued, "Don't worry about any noise we might make, Daddy promised to ignore it, and my mom's at work. Sissy told me a little about what happened during the blowjob, Scott."

"SISSY!" her brother hissed. "You said..."

"Scott, I told you we could talk to Anne-Marie about it, she won't ever tell." Sissy grinned, and said, "Anyway, she's GOOD at keeping secrets." She winked at her cousin, as Scott stared at them both, a puzzled look on his face.

"That's right, Scott," said Anne-Marie. "I promise that ANYTHING that happens in this room is just between us, you don't have to worry. Now then, tell me more about the blowjob, OK?"

"Well... I guess..." Scott said. He glanced at Sissy, who nodded, so he told the story of how he had unintentionally hurt his sister by forcing his penis in her mouth.

"A guy tried doing that to a friend of mine at school," murmured Anne-Marie. "He was a jerk, and didn't care that he'd hurt her! He bragged about 'face-fucking' her the next day, and half the school thinks she's a slut now. It's good that you realize that it's mean, and you don't want to do it again."

"I... I didn't mean to hurt Sissy, it... it just felt so good, and I'd seen guys do it in porn," whispered Scott. "Sissy... she wants to... to have sex with me, and I know the first time hurts for the girl. I don't want to hurt her again!"

"Well, you both love each other, so that will be a big help. Sissy, ahh... do you... have you ever masturbated?"

Sissy nodded, and said, "All the time! My mo... umm, someone at school even got me a viber... vibrator!" With that, she reached in her purse and proudly displayed the toy. Grinning at Scott's shocked look, she punched the button on the base, and said, "See? This feels so good on my clitty. I... I thought about pushing it through my... my hymen, but I was scared."

"Someone at school, hmm?" Anne-Marie shot her a piercing look, and Sissy was sure her cousin knew it was Sissy's mom. "Anyway, umm... would you feel embarrassed to masturbate in front of Scott and I?"

Sissy just giggled, and quickly stripped off all of her clothes. "I thought you'd never ask! My coochie's been tingling all day!" She jumped onto her cousin's bed, applied some of the slick gel to the toy, and started gliding it all around her little slit. "Mmmm... it feels SOO good!"

The young girl closed her eyes, and let the good feelings flow over her. She seemed to feel extra naughty, doing it right in front of Scott and Anne-Marie like this, and she wondered if that's how Emily felt when she showed off to Mr. Jenkins. Sissy giggled, and traced the tip of the vibrator all around her coochie, dipping it just inside the hole, then back out to bump against her clitty. She moaned as the vibrations made her tingle all over, and she reached up to rub one of her stiff little nipples. Recalling how Emily had put used her toy in her bottom, Sissy dropped her vibrator down to circle around her anus, and was surprised at the good feelings coming from that spot as well. "Ooo, that feels funny!" she whispered, as she let the toy rest there a few moments longer.

Sissy brought the toy back up to rub hard against her clitty, and knew it wouldn't be long until her 'gasm. As she got closer, she was startled to feel someone's hand pull the toy away, and she opened her eyes to see Anne-Marie, who asked, "Sissy, do you trust me?" Sissy nodded, her brow covered in sweat, and surrendered the toy to her cousin. Sissy could feel her tingles increasing as Anne-Marie picked up where Sissy had left off, the vibrator twisting around, slipping inside every now and then to probe lightly against her hymen.

"Oh... Anne-Marie, it's almost... almost there!" Sissy panted, her young hips thrusting up from the bed to increase the feeling from the vibrator. She felt Anne-Marie gently push the toy partway into her vagina once more, while the older girl's thumb rubbed against Sissy's clitty. The combination of the feelings from within her vagina and the pressure on her clitty sent Sissy over the edge, and she screeched as her body quivered into orgasm. Amidst the pleasure, Sissy felt a sharp pinch, but ignored it as the orgasm sent waves throughout her body. Finally collapsing onto the bed, she felt a dull ache from her crotch, and glared at her cousin. "You did something! What was it?"

"I'm sorry, Sissy. If I had told you what I was planning to do, you might have been scared, and that would have made it worse. Now that your hymen is gone, you can have sex without it hurting!" Anne-Marie held up the vibrator, and Sissy could see a small smear of blood on the toy. Curious, she reached down to feel herself, and winced a bit as her fingers encountered the ragged edges of her hymen. Sissy looked at her fingers, and could see a bit of blood on them as well. "Don't worry, Sissy. The bleeding will stop in a moment," said her cousin. "Let me go get a cool washcloth to put on it, that will help a lot!"

As the older girl left the room, Scott looked helplessly at Sissy, and said, "I'm sorry, I didn't know she was going to do that! Did it hurt a bunch?"

Sissy gingerly probed the tender area once again, then grinned. "Nah, it just surprised me. I skinned my elbow last week, and that hurt a lot more. Anyway, she's right, I would've been scared, and then I would have thought that it really hurt." Anne-Marie returned with the washcloth, and pressed it gently against Sissy's coochie. "OOH! That's coo-oold!" Sissy yipped, then sighed as the cloth warmed slightly. "It does feel good, though. Thanks, Anne-Marie, and thanks for... for doing that. I barely felt it, all I could think about was my 'gasm!"

"It's OK, silly goose!" Anne-Marie grinned at her, and continued, "I've heard several girls at school say that it can really hurt if you still have your hymen when you first have sex, particularly if the guy doesn't care about you."

"Good! I REALLY wanna... you know... have sex, with Scott! He's the best brother a girl could have!"

"Umm... about that. I... I'm a virgin, and I wouldn't know what I'm doing," whispered Scott, a deep flush on his face. "I... I wouldn't want to hurt Sissy again, even though her... her hymen is gone."

"Don't worry, cuz! That's the next step!" Anne-Marie pulled him close, grinding her crotch into his bulging erection as she kissed him soundly on the mouth. "Sissy mentioned that on the phone as well, and she asked if I could... umm... teach you!" She released him, and started taking off her clothing. "Well, go ahead, take your clothes off too!"

Scott glanced over at Sissy, who gave him a big grin, so he shrugged and started stripping. "I don't have a... you know," he said, blushing.

"I've got lots, and it's good that you thought about wearing one," said their cousin. She dug through a dresser drawer, and pulled out a condom. "Have you ever put one on before? Don't worry, I'll show you how. For Sissy's sake, I want you to promise to wear one with any other girl. If you do or not with Sissy is between you two."

"I promise," Scott said, as he finished undressing. "How do... AHH!" he yelped, as his cousin grabbed hold of his erect penis.

"Sissy, you should take a look to see how to do it, OK?" said Anne-Marie. "I want you to promise to make the guy wear one if you are with anyone besides Scott, all right?" As Sissy nodded, her cousin said, "You've got to pinch the end, to make room for the sperm, and then you just roll it down the guy's penis." She demonstrated, then squirted some of the gel into her hand and coated Scott's condom-clad penis with it.

"OK Scott, come on!" their cousin said, as she lay on the bed, and used her fingers to put some more of the gel on and inside of her vagina. "I'm more than ready, just line it up, and slide it in. Be sure and use some lube, especially at first, since Sissy isn't used to your penis being in her." Sissy watched closely as her brother approached Anne-Marie and guided his penis towards the girl's opening. "Ahh! That's good," panted Anne-Marie, as Scott pushed into her. "You can go deeper with me than you can with Sissy, at least at first. Don't push in too far with her, she'll let you know when to stop. Mmm... Now, pull out a few inches, then back in... Ahh, that's it. "You're... You're getting the hang of it."

"Oh, wow! Anne-Marie, his thingy is going all the way inside! Does it hurt any?" asked Sissy. Her brother began grunting with each thrust into his cousin, and Sissy grinned at the sight of his pale bottom bouncing up and down on Anne-Marie.

"N-No, it feels wonderful!" panted her cousin, as Scott increased his rhythm. "B-Back... Back when I first started having s-sex, it... it was a little painful from being stretched, but it felt so... so wonderful, at the same time. OHH! If... If you use your... your vibrator, and S-Scott uses his... fingers on you, it will stretch out, and it won't hurt! Mmm, S-Scott!" Anne-Marie brought her fingers down to rub on her clitty, and Sissy could feel tingles starting again in her own coochie as she watched the two cousins having sex.

Sissy felt more and more tingly as she watched, and she started stroking her clitty. She giggled softly when she saw the serious expression of concentration on her brother's face, and leaned in close to see his penis sliding deeply into Anne-Marie's vagina. The smell of her cousin's arousal and the sounds that arose from the union of the two bodies made Sissy's tingles even stronger, and she rubbed her little coochie faster and faster. "Ohh, Scott," she whimpered, "I can't wait until you're... you're fucking me!"

"S-Scott... Listen to your h-horny little baby sister..." Anne-Marie panted. "She... She wants you to do this to her, does that t-turn you on? Ooo! F-Faster!"

"Ohh! Anne-Marie! Sissy! It... It feels so good," groaned Scott, as his tempo sped up. "I... I think I'm going to cum soon!"

"I... I'm almost there m-myself, cuz!" Anne-Marie moaned as she increased the speed of her fingers on her clitty. Sissy watched with wide eyes as the two worked towards a mutual orgasm, and she rubbed her own little clitty faster and faster. "AHH! SCOTT!" her cousin yelled, "I'm... I'm c-cumming!"

Sissy bit her lip to keep from laughing at the silly look on her brother's face, as he shouted, "OH! Anne-Marie! I am too! I-I love you!" Sissy felt like her clitty was going to explode as she watched him thrust his hips deep between Anne-Marie's legs and shudder as his sperm shot into the waiting condom.

Sissy rubbed herself frantically, and gasped as she reached the pinnacle of her own pleasure. She squealed as the waves of pleasure rolled across her body, finally dissipating and leaving her as limp as the now-warm washcloth she'd discarded earlier. She giggled as she saw that Scott had collapsed face down next to Anne-Marie, both of them panting loudly. "There, now NEITHER of us is a virgin," Sissy said. "It was SUPER fun watching you both, my 'gasm felt even better than the one Anne-Marie gave me!"

"It... It was my pleasure," sighed her cousin, as she wiped some sweat off of her brow. "I... I like you and Scott, you're my favorite cousins, and if this helps you two have sex yourselves, then I think it's wonderful!"

"Oh... T-Thank you, Anne-Marie... I... I'll never forget this," panted Scott. "I... I won't tell anyone at school, either. You know how those kids are with stuff like this." He rolled over to face her with a puzzled look, and said, "Hey, wait a minute, we're your ONLY cousins!"

"Still, you're my favorites!" Anne-Marie stuck her tongue out at Scott, and Sissy giggled at the sight. "We'd better clean up, my mom will be home soon!"

"Your mom?" Scott sat up straight as the color drained from his face, and whispered, "W-What about your d-dad? I forgot he was here! Will... Will he suspect anything? Did... Did he hear us?"

"Probably, but don't worry, he won't get mad," Anne-Marie said, with a wink to Sissy.

Sissy giggled, and added, "Yeah, Uncle Frank is cool, almost as cool as Mom!"

Scott glanced between the two, and said, "We-ell, OK, if you say so. We do need to go, Sissy, Mom wants me to mow the lawn, and I think she said you need to clean your room."

"OK!" chirped Sissy. "Thanks again, Anne-Marie, for... for everything! I don't know when I want Scott to... to have sex with me, but now we'll both be ready!" Sissy went over to her cousin and hugged her, not minding that both of them were still nude.

"All right, kiddo, I'll see you later." Anne-Marie hugged Sissy back, then laughed as the younger girl headed for the door. "Careful, silly goose, you aren't dressed yet! Of course, my dad probably wouldn't mind, but your mom might have some questions if you came home naked!"

"Whoops! I was having so much fun that I forgot!" giggled Sissy. "Come on, Scott, let's get dressed and go home!"
