That would depend upon the species. Small cacti would take years to absorb that amount of water but a large, thirsty saguaro could absorb that in a few days.
The Cactus' roots are extremely long so that they can suck water up from far away and search for the water. They also have a shallow root system to absorb surface water when there is some rain (or even dew). The trunk of the Cactus is also a part of this as it acts as a storing place for the water. The Cactus' spikes are specially there so that insects and animals don't eat it; the spikes are modified leaves, this reduces the amount of water lost through transpiration.

to suck up the water to store it
They have thick walls to keep water in. They have lots of roots to suck up whatever water there is. They have thin spines to protect themselves from being eaten. They have no leaves that might release water. They have pulpy centers to hold water in.
It shouldn't have to soak in water. As long as you suck on it and get it moist before you play, you can play on it.
It can absorb and retain lots of water in a short time for later use It performs photosyntesis in a CAM system which saves lots of water It keeps the stomata closed during the day and absorbs CO2 at night It's leaves are thorns and the stem performs photosyntesis It's bloom is aimed at desert insects
They suck the water.
Cactus will only take up as much water as they need and no more. The reason cactus cannot live in a rainforest is that they will rot easily if they do not stay dry most of the time. They grow in sandy, well drained soil where their roots have a chance to dry out completely between rains. Therefore, they have never needed to develop defenses against rot-producing organisms. Most cactus also need lots of sunlight, a commodity hard to find on the rainforest floor.
depends how long she will suck your penis...
A syringe can suck water because water can change shape but cannot be compressed.
Elephants have over 100,000 muscles in their trunk. Elephant trunks can suck in over 2 gallons of water. Trunks are the largest type of nose.
About the only animal that will attack a cholla cactus are scale insects that suck the fluids from the plant and can eventually kill it.
