Help and tips for massaging my girlfriend.?

[Shard]

I wish to give my girlfriend a full on proper massage we were talking about it the other day and she said she really wants me to give her one but to give a proper one with lotions and all shed have to be naked.. Since we are only 15 her mum would scream at her if she was naked but shes completely willing to do it even though her mum would scream at her.. she wants a full body massage.. im wondering if i should get her naked to do it or get her to keep her underwear on.. it wouldnt be the same if she was in her underwear.. im really worried if she is naked i might do or see and stuff and i really just dont want to perv on her i just want her to relax and feel good and such from the massage.

Im just worrying over it all... If her mum caught us shed take it the wrong way and just go blahh at us... She really wants it because i give her massages all the time over the clothes but she wants a full on proper one with lotions etc... I want her to feel really good while im doing it.
I dont want her to be naked it just wouldnt work with clothes on though. This is ment to be all about her on this day that im going to give her a massage and ill give her what ever else she wants. I just want her to feel good and have a wonderful day one that she will never forget.

So should i get her naked to give her one? or leave her underwear on?
And if you have any tips or what not then please share them with me..
Id like any help and tips you all can share with me..

And also after and before the massage what should i do to make her feel good and if possible get her a bit horny because shes always so much cuter and her voice is so much sexyer when she is.
Something playful but will make her feel good..

Please be mature about this.. i don't want stupid unhelpful answers.

Thank you everyone in advance that helps

i agree with L B.
its better to have the underwear on and not to get naked with a 15 year old.

just give her the necessary massage without the need to make her feel horny.
wait til you guys are older, there'd be plenty of chances.

Do not under any circumstances get naked with a 15 year old. She is below the age of consent. Use your head!
