I new my girlfriend's younger sister was a virgin and ever since she turned 18 I always wanted to be her first. I spent many hours masturbating about the thought, but I never thought I would get the chance.
Whilst chatting to my girlfriend's sister Helen over the internet, she told me how she had never experienced an orgasm. She told me how she regularly got horny and tried masturbation but it had never worked and was getting frustrated. I offered a few tips on how to get herself off such as rubbing her clit whilst using a dildo or other similar shaped implements. She thanked me and said she would try it. I then logged off the computer and went to bed.
Friday night came round and I had forgotten all about our talk. I was with my girlfriend round her house and she had a call asking her to go into work. Her mom and dad were out all night at a party and my girlfriend left saying she would be back around 11 and that her sister was in the bath and if I minded staying at hers so her sister didn't come downstairs to an empty house. I said that it wasn't a problem and she left. After about an hour of watching TV I heard Helen call me from upstairs. I thought she had got a problem with her computer of something so I went upstairs to investigate. From outside her closed door I asked what was wrong.
'Come in please' she said, sounding out of breath and slightly annoyed. I opened the door to see what was happening.
'What's ...' I was going to ask what was up but before I could get the words out I realised that she was sitting on her bed with her legs stretched out in front of her with her clothes scattered over the floor. Only her towel draped over her like a blanket was keeping me from seeing her hot naked body. It covered her from above her breasts to just below her knee, with her gorgeous little feet poking out. I often gazed at her bare feet imagining sucking each toe in my mouth. I got an instant hard on and decided to sit down on the stool before continuing, just in case she saw it.
Finally I got my words out 'What's up? I muttered trying to sound like I wasn't about to blow my load in my pants.
'This is kind of embarrassing but I've tried your technique every night since you told me on Monday and I still haven't cum.' My hard on got even bigger and I was worried she could see it.
'Please don't tell my sister but could you please help me out, guide my through it, I really need to experience an orgasm, I don't want you to do anything you don't want to, you don't have to have sex with me or anything just guide me through it, its just..'
I cut her off knowing she was beginning to ramble and I didn't want her to realise how crazy the idea was and stop it before it started.
'Of course I will help you, what do you want me to do?' Trying to sound calm whilst wishing my erection would subside.
'I don't want you to see me naked so if I touch myself under my towel, I will describe what I am doing and you tell me what I need to do next?'
'That's fine with me.' I said but really i meant please let me touch you.
'Ok, dim the lights a bit please.' I did as I was told
'I am using my two fingers to penetrate and my two fingers on my other hand to rub my clit, is that right?'
'That seems ok, but if your not wet its not going to be comfortable. I need to know how wet you are before I can help.'
'I am not very wet but I cant seem to get myself wet.' She said sounding annoyed again.
'Ok if you really want to orgasm your going to have to let me touch you and see you, other wise I am of no help.'
'No I don't want sex with you, you're my sisters boyfriend.' She snapped
'I don't mean sex, just tickle you and caress you, if I cant see what you're doing I can't help.' My hard on had gone now as I was so worried I had blown my chances.
'Ok then, you will need to touch me first to get my going and then I will be confident enough to go further and show you mu body and don't tell my sister.' I thanked my lucky stars she didn't call the whole thing off.
'Ok I said, keep rubbing yourself while I work my magic.' I said with a laugh.
'And remember this isn't cause I want you, I just want to cum cus I am so damn horny and I know i can trust you.'
'Ok.' I replied.
I moved over to her and sat on the bed, I was on the end of the bed facing her with her feet right in front of me as she began to masturbate under the towel. I began tickling her beautiful feet expecting her to squirm but all she did was let out a little moan. Her pretty face was now pulling expressions of pleasure and I knew she was enjoying it. I rubbed both of her feet and asked her if she liked it.
'Yeah it feels great, don't stop.'
I carried on rubbing them not wanting her to be displeased and her facial expressions were causing my erection to return.
'I want you to kiss, lick and suck them.'
'What.' I said barely believing what she had just said.
'I know you love my feet, I catch you staring at them all the time, I've always wanted you to suck them, please do it for me.'
