Hey, hope you dont mind me slipping in here with my 2 cents worth.
My partner and i have been pumping for quiet a few years and have
totally adored the journey, discovering another side of our bodies.
A couple of quick tips if your starting out is to warm and lube your bits,
make sure you get a good seal and pump slowly and get a feeling of
the pressure and pump until its at a comfortable level.
It takes time! your pussy wont get all big and floppy within 10 minutes,
perhaps a good start is to hold continuous pressure for 10 minutes then
have a break for a couple, massage the area then start pumping again.
Just to let you know, i generally pump for at least an hour and in this time
i release and pump periodically. most of the time i will be doing computer
work or just relaxing watching TV.
Like i say, it takes time, and for me certainly worth the wait, my whole
pussy swells and feels incredible to play with.
I have never had any health issues from pumping, only joy, she always
deflates back to its original shape.
Hope this helps a little bit, feel free to ask me any questions as iam sure
i could answer them on this yummy topic.
N xoxo
