In the first picture she is (hopefully) being impregnated.
Laura must now keep her rear end elevated for 5 minutes. She is very cooperative for this.
I thought this picture was kind of cool even though you can't see it very clearly. It is a slide of the very mobile sperm. They graded it at 60% motility which is pretty good. I think it is great for 19 year old semen! They looked like little tadpoles swimming around.
