Cruising with Sex Ed

The next few days passed without event. I tried to avoid Michelle - it's what you do after you've fucked your sister I think - but she kept up the facade in front of the other's giving me quick kisses and hugs when they were watching. In the meantime I grabbed any moment I could to talk to Allison and in one private moment she even kissed me. Not a peck on the cheek but a long passionate exploring kiss - exactly as Michelle had taught me to do! But then she'd be with Brad - the blond dude - when we were all together.

On the third night Michelle asked to talk to me so we went back to our family room. Mum and Dad were socialising so we had the room to ourselves.

'So little Bro we've gotta talk. Have you made any progress with Allison yet?'

'Eh no not much, talked a bit and I reckon she likes me cause she kissed me last night, but she's still with Brad I think. And errrrr Sis, are we okay...you know after the other night?'

'Andy of course we are. It was weird the next day but actually it was kinda fun and I like idea of being your teacher if you still want me to of course.'

'Emmmm yes! I mean to be honest it was great and I feel more confident with Allison already so...'

'Yes Andy?'

'Well...can we practice more?'

Michelle smirked at me with a cocked head; 'Well if I help you maybe you'll help me with Stacey. I haven't even spoken to her and I don't really know how to even ask her if maybe she's interested in me. This is all a bit new to me trying to pick up girls!'

'I'll do anything for you Sis! You just ask and I'll do it!'

Michelle put a hand on my expanding groin; 'Well can you ask her if maybe she is Bi? Whether she might fancy me?'

My cock stiffened under my straining jeans; 'Yep no problem I reckon I can do that.'

Michelle undid my fly and took my now bulging cock out of captivity. My big Sis looked me in the eye, looked down at my cock, smiled and kissed the head; 'okay lesson two big boy. You can't expect a blow job without some encouragement - us girls like to feel appreciated you know. So, stroke my face, look me in the eye, say something sweet to encourage me. Make me feel wanted and that giving you a blow job will earn your affection.'

Michelle took my cock into her mouth and moved her lips down my shaft so I felt the tip on the back of her throat. I stroked her face, kissed her hand, and told her how much I loved that and how beautiful she looked.

'Good start kid. Now you can be a bit more intense and maybe push my head into you a bit - but not too rough okay?'

Taking her lead I held her head gently and pushed my cock further so she gagged a bit, then I held her there but only enough so she could pull back if she wanted. It seemed to work and when I let go she started sucking up and down on my cock bringing tingling sensations throughout my body. This was amazing!

'Ok Andy see if you can get me to cup your balls - you might even get them kissed if you do it right.'

I stroked Michelle's short hair then, looking her in the eyes, took her hand and placed it over my balls squeezing her hand so it squeezed my balls. I moaned completely naturally - it was so good.

When I took my hand away Michelle kept on squeezing and rubbing my balls whilst taking my cock even deeper into her throat. I was getting close so I pulled my cock out a bit and, picking up on my state, Michelle wrapped her fingers around the base of my cock and squeezed. 'When you want to avoid coming just do this then your girl will know what you want.'

Michelle held tight through a few jerks and a little pre-cum showing, then licked off the pre-cum and pulled my head down to kiss me; 'if you want to be sucked off you need to share the taste.'

It was odd tasting my own pre-cum but it wasn't that bad and I figured that was fair enough.

'But what if I cum in a girl's mouth? Am I supposed to taste it?'

'Hell yes Kiddo! You want a girl to swallow your cum you gotta be prepared to at least taste it!'

That threw me and didn't sound good but with my cock in her mouth and being so close to coming I wasn't going to argue. And actually that pre-cum tasted okay once I got my head around it.

Now Michelle was bobbing up and down on my cock with increasing speed and intensity, my cock disappearing inside her mouth and hitting her throat on each stroke. She's squeezing my balls hard and with her other hand is rubbing my butt too; 'Andy there's one last thing you'll want her to do. You got to take her finger, lube it, and place it on your bum hole asking her to slip it in there.'

'What? No way!'

'Trust me Kiddo you'll love it.'

Without asking she stuck her finger in her cunt to get some juice on it, then gently slid it into my bum! It was amazing! My cock seemed to find a new life and intensity altogether and I started pounding into her mouth pulling her head to me and shaking still closer to coming; 'Oh fuck that's fucking amazing, don't stop please, please do that, oh fuck I'm going to cum'.

It felt like my balls were going to burst and when I came my knees went weak and my body shook all over. The release was intense and gushes of cum burst into Michelle's mouth. She swallowed a load but more came and dribbled out of her mouth down her front. I held her head still while my cock twitched and kept spurting cum into her mouth. The sense of release was intense.

Michelle swallowed more; 'Jesus Bro what the fuck! You've got balls full of the stuff! That's amazing! Come here you.' Michelle pulled my head down and kissed me pushing her tongue into my mouth and depositing some of my own cum into my mouth. At first I pulled back but she held me still and made me taste and swallow it. Once I got over the shock I found it wasn't too bad and as she said if I expected girls to taste it then it's only fair. After a while of her tongue in my mouth I realised it's actually a nice taste! Horniness does things to you.

After cleaning up we hatched a plan. I wanted Allison, so Michelle would flirt with Brad so he would split from Allison, or Allison would simply get pissed at him eyeing Michelle. Michelle was, let's say, better endowed than Allison with bigger tits and shapely bum so we reckoned Brad would fall into her trap.

In the meantime I would corner Stacy and sound her out about any possible attraction to Michelle. It was three days to my birthday and my new relationship with my big sister was proving both educational and devious. Plus fucking sensationally sexy!

That evening I sat with a group including Allison and some others when Michelle walked in the room wearing the skimpiest sexiest goddam outfit I ever saw. A tiny pair of cut-off shorts that clearly showed her bum cheeks and even a little bit of the lace of the skimpy panties underneath. On top just a small tube with no bra, showing her cleavage and the bounce of her tits. She had a ring in her belly button and smart slip-on low heeled sandals. She'd pulled back her hair into a tight bun and with just a little make up had a sort of boyish face. Every guy, and a few girls, in the room watched her walk in. Interestingly I noticed Stacy watching intensely and smiling. Brad had certainly noticed and shifted in his seat to make room next to him - though probably not expecting her to actually sit there as she was heading for me.

Michelle walked straight up to me without a sideway glance, leant into me, kissed me fully on the lips, and said 'hello lover' loud enough for Brad and others to hear. Then she looked around, saw the space next Brad and went over to him; 'is that for me Brad, how sweet of you'. Others thought she meant the space he'd made but she was clearly looking at his crotch. Jeez my sister is great tease! She sat right down, stretches her legs out so all could see, and asked Brad to get her a drink! The guy didn't hesitate; 'err what do you want?' Brad went off to get Michelle a drink leaving Allison siting there wondering what the fuck was going on. That was my moment I reckoned so I went over and asked Allison if she would like a drink. She seemed a bit confused but then said yes and I went to get her a drink. While at the bar I turned round to look at the group and noticed Michelle had now sidled up next to Allison and was talking to her, faces close together. This was going to be interesting!

'Here you go Allison one gin and tonic as ordered. What have you two been saying then?'

'Oh, Michelle was telling me a few things she thought I should know and it was...well very illuminating!'

Michelle busted in; 'Girls talk Andy - you should know not too ask!'

Andy came with Michelle's drink and she stood up, took the drink, and demurely leant forward to say 'thank you' in a whisper. Andy leant closer to hear and Michelle, right in front of us, kissed him fully on the mouth. 'That's for the drink handsome.'

Poor Allison looked a bit stunned, but not angry. I seized the moment and grabbed her hand pulling her up; 'come on Allison let's dance'. My timing was perfect with a slow cover being played so I held her close and moved slowly. I can't dance for the life of me so it suited me!

'So Andy, Michelle tells me that she doesn't have any claim on you, what do you I think she means by that?'

'Ah! Well I guess she means we are both free to meet other people if we want.'

'And do you want?'

'Eh yes I kinda do.'

'Come on Andy spit it out for god's sake!'

A week back I would have run away right now but Michelle's lessons had given me new courage and confidence. I looked Allison in the eyes (god they are so beautiful!) and kissed her cheek. I looked again to gauge her reaction and seeing a smile I kissed her fully on the lips, gently at first but then, when she kissed back, deeper and longer. Soon we were snogging on the dance floor oblivious to others in our own little world. 'Allison, I really like you. I think your stunning.'

'Well Andy thank you, that's a lovely thing to hear'

'You are absolutely beautiful Allison.' I kissed her long and put my hands on her bottom as we moved slowly, except by now the music had stopped and we were still snogging on the dance floor.

Allison broke the trance first and looked to where the others were seated. All but two had gone out for a dip leaving just Michelle and Brad, and Michelle was sitting on Brad's lap kissing him. Michelle stopped the kiss and looked at us over Brad's shoulder, winked and smiled. Damn my sister is good!

'Well that seems to leave me free to pursue other interests then Andy. What say we see if we can find a spare spa pool eh?'

We did find a spa pool, and it was empty of people, and fairly private, and no we didn't have our togs with us. Michelle taught me well, now was my chance to show what I had learnt.

To be continued.
