hmmm ok how to describe it?
Well first of all you may find at the very start, getting it into a good position and getting initial suction could be a bit fiddly. I would say, aim to have the top of the cup sat on the mound, just above her clit, maybe an inch or less above the top of her clit. If you go any higher up, any movements from the hips tend to cause the mound to move too much and the suction breaks. If you have it positioned here but the bottom of the cup goes over or close to her anus you may find you need a different cup ( I went through three different pussy pumps before I found the perfect size, it was like goldilocks and the three pumps, but anyway...) If you have a larger cup that does suck her bottom this can cause you to not get full benefit from the pump, because, that hurts!
Anyway on to the first pump....The best thing to do is only squeeze the bulb half way depressed, and try positioning and release slightly, if you see everything starting to suck into the cup then success, if not keep figeting around a milimetre here or there until you get that happening. Also I would advise you to push on it a little. Not much but give it a little push and wiggle against her pussy, it just helps to create than initial suction if everything is nicely moved inside.
The first suction feels nice/strange/horny at the same time. You start to feel the pressure sensation of your lips being sucked, and even the first suction using a pussy pump is more intense than a guy just sucking with his mouth. I think because it is spread over the whole entire area and every part that is inside the cup feels this suction. One of the nicest parts about the first suction is that I can feel it most on my clit. It feels like it would if someone was gently sucking there and it makes me horny. I would adivse, after the first pump, to stop for a minute, just to allow her to feel her clit get hard and feel that unique sensation and watch her squirm a little with pleasure (At this point it shouldnt be uncomfortable, so it will feel mmm) However, over time, once she has been taken to her limit and held it, then release it a little, then pump again and you will find she can go a little further. Make sure you do release it every so often, as it feels amazing when you start again! and you wont lose any of the benefits you already achieved. Plus, constant, constant suction can just be too much....play around.
After the first pump it starts to feel more intense, I guess I can only imagine it would be a similar experience to using a penis pump, so if you can imagine how one of those would feel, you might be able to put yourself into her shoes as to how it is feeling. I can tell you that with my pump, I can only get between 2 to 4 ish, more pumps, after the first one, before I am at that stage where it is very intense and I need to stop and hold it there for a little while (30 secs/minute) The sensation is intense, it is pleasureable. (Constant suction on your clit, the naughtiness of it all etc) but also, uncomfortable (Think lovebite, you know that hard suction sensation?) but it is strange because it feels...nice. Even though it is slightly uncomfortable. Its hard to explain I guess. For me personally, I like to be taken to the point where I am panting or squirming because it is intensely nice, but hurting. Thats just me though. Bit of a masochist and have a D/s relationship where we like playing those kinda games.
In my experience you need to be doing this for prolonged amount of time (30+ minutes) to start getting a pumped up pussy kind of look. And with standard pumps like you can buy from Lovehoney, you wont get that dramatically hugeeee look that you see in porn. (Seriously I think they have some kind of machine to get them looking THAT) huge. But you will see a reasonable difference, at least double the usual size if you do it for a while and keep pushing her to that point where she is justttttt at the edge of it becoming a bit too much. Does that make sense?
And as for after .... Once you have finished playing and remove the pump, this is when you experience the benefits. Everything is sooooo sensitive. try gently, gently running your tongue over her lips first, avoid the clit at first and play/lick around it...It feels amazing really, you feel so sensitive that it has potential to make me orgasm just through that. be gentler than your usual technique would be my advise because of how much more sensitive the whole area is. Light teasy touches should have her right where you want her.
Ok....I know what I am doing tonight now! lol :D Update us. Cant wait to hear how you got on x
