In a story about an athlete's career. As the athlete gets older, injuries and the intense competition start to drain their vitality. Their once - high - energy performances become less frequent and less spectacular. This is a metaphorical use of 'vitality drain' that has nothing to do with anything sexual but rather shows the natural decline in a person's ability and energy in a particular field.
Another interpretation could be in a post - apocalyptic story. There might be some sort of environmental factor that drains the vitality of living beings. Maybe there's a strange radiation or a new type of virus that gradually reduces the strength and energy of people, much like how a real - life illness can make a person feel drained of all their energy.
There are some works in the vampire erotica genre that feature vampire drain stories. However, they are not as mainstream as regular vampire stories. For example, there are some indie novels that explore this theme in great detail. These stories often blend the elements of vampirism, sensuality, and the act of draining in unique ways, but they may not be widely known to the general public.
Well, often in such stories, there is the theme of immortality in relation to the vampire's draining. The act of draining can be seen as a way for the vampire to sustain its eternal life. And there's also the theme of transformation. Sometimes, the victim may start to transform into a vampire themselves during or after the draining, which adds an element of mystery and horror.
Open ditches and underground ditches were two types of drainage ditches. Open ditches referred to visible drainage ditches, often used in places such as roadsides and stadiums. Water could flow directly into the ditches from various locations. The cover was usually a comb or grill, which could pass water and intercept debris. A hidden ditch was a ditch that guided water below the ground. It was usually used to lay water pipes, electric wires, and other pipes. The cross-section was larger than an open ditch. The cover was usually steel plate or concrete. Water could not flow directly into it, and the cover could not block it. Open ditches were suitable for excavation and helped to discharge surface water, which was beneficial to the regulation of underground water level and soil moisture. The underground ditch could drain water quickly, occupy a small area and have a small amount of earthworks, which was helpful for field machinery operations.
One horror story is about a child getting their hair or limb stuck in a pool drain. The powerful suction can cause serious injury. For example, a little girl's long hair got wrapped around the drain and she was trapped underwater until someone noticed and turned off the pump.
One horror story could be that the french drain was not properly installed. For example, the slope was incorrect. Instead of water flowing away from the house as it should, it started pooling near the foundation, leading to water seeping into the basement. It caused mold growth and damaged stored items in the basement.
In some countries where homosexuality is still not fully legalized or socially accepted, gay people who are highly educated and skilled might choose to leave.
