A video demonstration

"While I am sure you would all like to see an in person example of breeding I don't think that the janitors would like it very much if we made a mess so a video will suffice for now." The teacher said as several groans from the futas of the class filled the air along with relieved breaths of air from the boys.
"Now, now I'm sure you all will live. Now before we begin let me clear some things up for the class regarding basic biology. We futas are unique as we do not show up in any other species in nature. In nature especially in our fellow mammals they can be divided into what is called male and female. A male in every other species with the exception of she horses is not the one to give birth. And will get the female pregnant. In humans the futa is unable to become pregnant so instead the male fulfills that role. Now this might lead you to ask why do males have cocks if they cannot breed? Well some scientists believe it is a vestigial organ. Others believe it is just a very pleasurable part of the body and has kept improving quality of life for the species. Now even if they can't breed males are still attracted to futas and as such our society can continue. Now to the video." She said as several of the males flushed as futas smirked. Vince wished as his cock strained in its cage, he really needed to get it off! But he would have to go to a state office for that?! He really did not want to do that as it would mean telling his mothers about it and they would have questions especially his younger sister!
"Now what kind of video shall we watch class? Would you prefer a more solid educational video about the basics, or would you prefer a more common made at home video of two people mating and a futa breeding her male?" Miss Winter asked essentially asking the class if they wanted to watch porn instead of offical material causing murmurs to fill the room as she coughed.
"Now raise your hands. Will we watch an official documentary or something more... down to earth shall we say?"
