Also I don't think it's possible to see the cell in the semen if it's old? I'm not really sure if I phrase that right. sakura
There are ways of preserving biological materials. You can even store them outside of the fridge. Don’t know how they do it though. Speaking from experience.
This was okay for me, the first story lacked something since I didn't really feel love from the seme, just convenience.
The second story was kinda gross, don't walk around with sample slides in your pocket, ew. And how did they not degrade?
