Since their frantic session at Monday lunchtime they had not so much as touched - merely acted out the roles of firm friends. Triana was beginning to think that maybe the whole experience was just a one off - maybe it was some sort of initiation right that new students went through.

However, when her mother had announced that she and her father were going to the neighbours for dinner and that Becky was going to come round and keep her company, Triana was more than keen.

And she didn't have to wait long. Becky came round early, made her acquaintance with Selina and Jim and basically made herself at home. As soon as Selina and Jim walked out of the door, however, Becky bounded upto Triana, flung her arms around her and kissed her hungrily and passionately fully on the mouth. Triana responded enthusiastically - relieved that Monday's session did not now seem to be a one off occasion.

"Oh, Tri - I've been so horny since we fucked on Monday - I've just been dying to get my hands on you again. " Becky gushed when she finally broke the kiss"Are we going to be alone tonight"

"I hope so" answered Triana."My brother Billy went out with some mates from school - he'll be gone until at least nine.

"Great - shall we go to your room"

The two girls bounded upto Trianas room - as soon as they got in Becky started ripping off her clothes. Triana, seeing her friends lead, followed suit and in a minute they were both naked. For a brief moment they stood looking at each other, then they came closer and reached out a hand to each other.

The kiss this time was less frantic, slower, more calculated - but the passion was no less intense. Their tongues entwined in each others mouths as their hands gently explored each others bodies.

Triana was nervous - even though they had explored each others bodies only a couple of days ago - somehow this was different. Monday had been so new, so different - most of it was a reaction. But tonight - tonight was more planned - it was almost as if she were a new person - she wanted to do this right with Becky. She understood her friend had a lot more experience in this - but she was keen to show how much she loved it.

Very gently, Becky pushed her friend to the bed. Triana complied readily, looking up and Becky and realising that the girl placing her face close to Triana's sex. Becky ran her finger along Triana's slit and watched Triana's face as she bit her lower lip. She spread Triana's lips apart and found her swollen clit. It was pulsing with desire. Becky ran little circles over Triana's clit and smiled with the soft moans coming from Triana's lips. Becky liked the response she was getting so she licked her finger and inserted it slowly into Triana's tight little hole.

And it was tight...nothing had ever penetrated it before. Triana squeezed her eyes shut, concentrating on the sensation of her friend finger fucking her hole. Becky increased to two fingers, slipping in and out easily into Triana's willing pussy. Soon she was easily fucking Triana with her fingers and Triana's hips were matching her rhythm. She glided her thumb up to Triana's clit and rubbed that while she finger fucked her. Triana's moans were getting louder and Becky was getting more turned on. She started playing with herself. Her own pussy was drenched.

Becky bent over Triana's sweet pussy and could smell the soft musky odour. She inhaled it deeply. She spread Triana's lips and ran her tongue up and down slowly. Triana lifted her head and opened her eyes. She smiled at her friend to lt her know how much she loved it. It felt so good to have Becky's warm tongue on her aching pussy. Triana's clit was huge and throbbing, begging for release. So Becky nibbled on it. Sucking gently on Triana's clit. She brought her fingers back into Triana's tight hole and fucked her with them while she licked at her clit. It became more difficult as Triana started bucking her hips against Becky. Her moans were turning into screams and she was clutching at the pillow next to her. And with one final scream, Triana released her first orgasm of the evening. Becky's face was drenched with Triana's sweet juice. As she licked her lips, she moved up towards Triana and kissed her deeply, allowing Triana to taste herself.

Triana could barely move her body, but she knew that she wanted to return the favour. She was a little embarrassed at her attempts to finger Becky, it hadn't seemed this difficult on Monday, she thought - but she knew what Becky had just done to her that made her orgasm and so just tried to do the same back. She was surprised to see how wet Becky's pussy had gotten. She slid her fingers easily into Becky, feeling the walls of Becky's pussy tighten around her fingers. She liked the soft silky feeling of Becky's pussy. After a few minutes, Triana gasped as she realized that Becky had no hair on her pussy. She was too embarrassed to ask about it, but wanted to get closer and look.

"You like?" asked Becky "I just shaved before I came out - I love how smooth it feels"

Triana bent her head down to Becky's pussy to inspect it. There was not a hair to be found and Triana was surprised at how much Becky's' bald pussy turned her on. She licked her way around Becky's pouty lips and eagerly shoved her tongue inside. Becky's pussy tasted sweet. Triana licked it all, stopping to push her tongue in and out of Becky's hot little hole a few times before working her tongue back up to Becky's clit. Triana listen to Becky moan. Becky rocked her hips up against Triana's tongue so Triana slipped two fingers deep inside Becky. Becky's hips rocked faster against Triana and Triana got more excited. She licked hard and fast and pushed her fingers deep into Becky, adding a third finger as Becky climaxed against her. She licked up all of Becky's sweet cum.

"Oh God, Tri, that was amazing - I came so good" cooed Becky after she came down from the euphoria that had accompanied her orgasm.

Trians scooted up and kissed her friend. Becky tasted herself on Traians tongue. "Mmmmmm.... I hope you enjoy my taste as much as I do". The girls hugged and lay on the bed. What a great feeling. Then out of nowhere, a slow hand clap. Both girls looked up to see Billy standing by the door, slowly clapping his appreciation and smiling.

"You girls put on quite a show... fantastic" Triana was about to go ballistic - her own brother had walked in on her having sex with a girl. She was so embarrassed - no, she was just plain mad. Trust her stupid brother to spoil things. But Becky was quicker with her reply.

"Hi Billy - why don't you join us - I can see your cock is keen to play from over here". Becky had easily spotted Billys prick straining against his jeans to be released.

Billy sauntered over - he wanted to look cool and calm - but in truth he was as hard as iron - the sight of watching his sexy sister fuck the gorgeous neighbour almost had him creaming his pants. Now it looked like he might get some action. He stood by the bed. Becky leant up and started to unzip his fly. He helped by popping the button.

Triana looked on as her friend pulled down her brothers' jeans and underwear with one tug. She looked intently ay her brothers' big cock. In all her 16 years she had never been this close to a cock. Sure she had actually wanked a cock about six months ago - but it had been a fumble job - she had never even seen it. Billys cock fascinated her - it was hard and big with an angry looking purple knob. She looked on intently to see what her friend would do with it.

Becky too liked what she saw - she was used to playing with older guys - but she was very impressed that Triana kid brother had a big tool. She ran her tongue over her lips and gingerly moved her mouth closer to it.

Billy was having a difficult time not shooting his load there and then. A blowjob from this hot looking chick would be heaven he decided. Instinctively he edged closer so that his prick was now touching her lips. Becky's tongue met the knob of his prick and licked it. Billy closed his eyes at the pleasure he was feeling. Triana was getting so turned on watching her friend suck off her brother - she spooned in behind Becky and began massaging Becky's tits.

Becky started to give Billy the blowjob of his life. She eagerly started to suck him deep into her throat and then suck him as if his cock was a straw and she need to suck the cum from his balls. It felt so good Billy - he wanted the moment to last forever.

"Oh Becky" he murmured "You are such a great cock sucker... mmm ... yes baby... suck my big prick" he continued

Triana loved to hear her brother talk like that, she was now playing with Beckys pussy - her friend was really wet and Triana's fingers were sawing in and out of her wet pussy. She could tell her friend was working her way towards her second orgasm.

Becky was close - she knew that. Triana's fingers were working magic on her fiery clit and she was in danger of going ballistic. She wanted Billy to spew his load into her mouth - she held the base of his cock and fucked his meat with her mouth. Then she brought her fingers to his balls and tickled them lightly. Billy, who had been doing a sterling job of holding off his orgasm, just lost it

"Oh, fuck....." he cried out as his knees started to buckle and he fired gob after sticky gob into the hot blondes willing mouth. Becky sucked him still, swallowing all that he had to offer, small drops of his jism leaking from the edges of her sweet mouth. It was enough to finish her off too - another gut wrenching orgasm overtook her and she surrendered to Triana's expert touch

Billy collapsed on the bed with the two girls. Triana was finding it weird to be next to her brother naked, but she had to confess that he was a beautiful specimen of a man - and she knew that she was very horny.

"Oh, boy" cooed Becky " that was so good. Tri, I'm sorry, I should have let you have him too. Say Billy, can you get it up again so that your sister can have some fum"

Both Billy and Triana blushed deeply - neither wanting to admit to the other that they were actually thrilled at the idea.

"Oh God, Becky.. no.. I'm not ready for that yet" stammered Triana

Becky realised that maybe she had gone too far. " Sorry, tri, I didn't know - you mean you're still a virgin?"

"Well, I've never gone all the way with a guy" replied the nervous girl.

"Oh Baby" Becky said and hld her friend close. " Do you mean that you don't find Billy at all attractive?"

Triana realised that now was no time to be shy and embarrased - after all she wass lying naked on her small bed with her new best friend and her brother - all without clothes.

"No... ots not you, bro.... I actually got so turned on watching Becky suck you off - I really wanted to let you fuck me... its just I'm a bit nervous"

"I'm a bit nervous too, Tri. "replied her brother "In fact I've not fucked a girl myself - just had blowjobs - they've been great - but I'm sure it's not the same as fucking"

"I don't believe it - you guys - you mean your parents haven't shown you all about the facts of life?" Becky started to chuckle obscenely "You've been deprived of a great education"

"We both KNOW about sex, Beck - its just that we haven't done it" Triana cut in.

"No- what I mean is your parents have SHOWN you about sex. Jeez, my Dad fucked me when I was 14, and my Mum let my brother fuck her when he was about the same age. There's no better way to learn"

"Shit, you're kidding - you fucked your Dad" cried Triana - vivid thoughts of her and her Dad filling her mind. She already liked the possibility.

"Yeah - you interested?"

It was Billy that spoke up for them both this time.

"Jeez, yeah - of course _ I've been wanting to fuck Mum for over a year now"
