So far:
I fancy my slightly older sister, Jenny. It seems mutual. We have played a clothes swapping game. She wanted to watch me wear more of her clothes and wank while she fingered herself underneath a blanket. Jenny played with my cock and we told each other our fantasies. Mine are about being dominated. Hers was about watching me have sex with another boy - and it made me cum in front of her.
We swapped underpants and met up during lunchtime at school to show and tell. When we got home she asked me to wank for her and gave me a female anatomy lesson. I kissed her arse and watched her wank while I started to tell her about the time I jerked off with a male friend, she watched me cum into her panties at the same time she came while fingering herself. She wiped her cunt juice on my shoulder.
A few days later Jenny wanted to practice fitting a condom to my erect cock.
Overview of this chapter:
Jenny fits the condom, watches me wank, and gets up nerve to ask me if I want to lick her cunt. We visit the beach and make plans for our 'weekend of sin' (her actual words).
Jenny took hold of the shaft of my cock with her left hand to steady it. Her hands felt so warm and dry; my hands were trembling and my palms were sweaty but my sister's hands were rock steady and her palms were dry. It was truly all I could do to keep from spurting all over her hand. Her thumb and forefinger were circled, firmly, just below the head.
Then Jenny knelt down and bent over - not far - just a half bow. Her hair fell forward and brushed my cock. I felt her hot breath on my belly and cock. Then she gently placed the rolled condom loosely on the head of my cock. She looked up to make eye contact,
'How does it feel, Ian?'
'Really good. I love it when you touch me. I love it when we do anything.'
Jenny shook her head making the tips of her hair tickle the shaft of my cock.
'No, I mean how does the condom feel?'
'Well you haven't got it on yet. Do you want me to do it?' I asked hoping she'd say no. Jenny was intent on doing this unaided and shook her head again. The smell of her hair - green apples - as it brushed my cock -- was driving me wild even though it was the same shampoo I used.
Using both hands now my sister began to roll the condom down. Then she stopped. The broomsticks at school were all smooth shafts and I realised that Jenny had no idea how to get the condom over the edge of the glans.
I started to reach down to help but I needn't have worried because she was good. I barely noticed it as the condom snicked over my glans. I didn't really feel anything until she used both hands - one on either side - to rapidly roll the condom down the rest of the shaft. That I did feel.
I gave a wee lurch and a gasp from excitement and Jenny looked up.
'What's wrong? Did I hurt you? I'm sorry.'
'No, no, you didn't hurt me. It just felt so good when you did that.'
I daresay that the broomstick she had previously practiced on was less sensitive than her brother's penis and didn't mind a fast unrolling. But not to worry. I was now fully clothed, so to speak.
Jenny stood up and stepped back to admire her handiwork. She reached down and jiggled the rubber ring to check it was forming a seal and checked the teat wasn't inflated - just as the embarrassing school lessons had told us to do.
'Well how does it feel now? Is it too tight? Too loose? They said you can get other sizes but for almost all men like you the normal ones will fit. Hmm, actually I can see it is a good fit.'
Men! I heard that! My teenage sister has just put a condom on me and described me as having a man's cock!
'Is it ok having it all squeezed in like that? Look, I can see the veins all bulging.'
'It feels fantastic Jenny. I mean it. Thank you so much for doing this with me. What do you want to do now?'
Jenny told me to stop and wait. She was still kneeling - with her knees about as far apart has her shoulders. She bent backwards a little, arching her back, slipped her hand down into the pair of my underpants she was wearing, and gave herself a good rub.
Clearly I was staring and she seemed to feel an explanation was due.
'Just spreading some of the juices. Here.'
"Here" meant she pulled her hand out and raised her finger so I could see the glistening. She stood up and put her ankles together. She stuck a thumb in either side at her hips and peeled the underpants down - man I loved the way she did that. Then she stepped out of my underpants and kicked them to the side. She lay back on her bed and spread her legs. She began rubbing in a circle.
I couldn't really see much detail as her hand and cunt hair was in the way. But I could see enough, she had her first two fingers stretched out in a sort of Spock symbol. The fingers were towards the top of her cunt and on either side of where I knew her clit was. She was rubbing in a circle but without the fingertips moving from where they were pressing. I could see flashes of the pink of her inner lips - the labia minora as I now knew they were called - with each turn of the circle she was rubbing. Her other fingers rested at the entrance to her cunt.
'More please' I begged. I knew I'd said the right thing because she gave her wee triumphant smile
I looked at the condom and asked 'Shall I take it off?'
'Umm not right now. Would it be OK if we checked how it works?'
I practically came there and then. Surely she didn't mean...? Jenny saw the look that had flicked across my face.
'No, I don't mean that. Anyway, not yet', she said. 'Or maybe never' she added hurriedly.
But she had said "yet". Maybe one day?
She clarified; 'I mean I want to see what happens when you, you know, when you umm cum inside it. Will that be ok?'
She was cajoling now but she should have known that I was hers to command. Would it be OK? Did she really need to ask?
'Yes, please, Jenny, please, I really want to show you.'
We'd done this sort of thing before. Jenny was watching me wank while she sat on her bed with her legs spread and her hand reaching down the waistband of the pair of my underpants she was wearing. But this time she was naked and I could see her cunt wide open.
'No Ian, what I mean is, can I do it this time?'
I almost came then. My sister had just asked permission to jerk me off. I suddenly guessed she had wanted to do this without getting cum all over her and come up with the idea of putting a condom on me for this reason. Well, I sure as hell didn't mind. It wasn't going to be skin to skin contact but it was still going to be my sister holding my cock.
'Sure, I would really like that Jenny. I usually do it like this.'
I took a grip and gave an experimental tug. I was surprised at how little difference I noticed and told her so.
I closed my eyes for a moment and then felt Jenny's hand peel my own hand away and take over the jerking. I snapped my eyes open and could see all the fingers of her other hand were buried up to the palm knuckles in her cunt. Naturally I came instantly, but if Jenny noticed she didn't show it and she continued to tug on my now quite sensitive cock for a few more seconds before she closed her eyes and gave several big heaves.
She squeezed my cock hard and clenched her thighs around the fingers in her cunt and shuddered a few more times. Then she opened her eyes, let go of my cock and parted her thighs. I bent closer to watch her pull out the fingers from her cunt. Her fingers were totally dripping and I wanted so much to suck them clean.
'Can I...?'
Jenny held up her hand and I leaned forward and took those fingers into my mouth. I closed my lips around the 3rd knuckle and moved my head back to slurp her fingers clean. In all the years since then I, have never forgotten the taste of her teenage cunt juice.
'More please Jenny?'
'Soon Ian. Not this time, but soon. Wait for Festival weekend.'
She said this with a sly grin. My sister knew exactly how crazy she was making me. (If you have been paying attention you'll know that Jenny and I are going to be left at home for a 3 day weekend while our parents go to a folk music festival).
And again there was the odd guilty thing as our breathing slowed and we did the by now routine job of cleaning up and practically pretending nothing had happened.
But this time as we were about to go to the living room to watch TV shortly before we expected Mum and Dad to get home, Jenny said:
'I will have sex lots of times in my life but I the first time should be with somebody who will always be important to you. Lots of things will change in our lives but we'll always be, sister and brother. Some of the girls at school have had sex and already can't stand the boy. So we should be the first for each other. And I mean we should make sure that we do everything first with each other.'
