Which one would you recommend for the first time punting?
depends what you are looking for...
LSS will have your cock in her mouth before you have got out of the hallway...or out of your trousers. You will get ravaged, in a fantastic way.......so if you want to be ravaged, LSS is your girl
SLfY will slowly seduce you...tease you, play with you.....and if you get her muttering filth in Portuguese....heaven!
Both are excellent choices - the best in Reading by a mile IMO.
Really depends what you want - both will put you at ease and you will have a ball - but be spoilt forever! its not normally like that every time I can assure you.....
You'll have to do them both and report back!
