Taking your sperm for science.  |  (Random)

My step-sister and I are horrible at science. Now we have a project due in class and know we will get a crappy grade like all the other assignments we've tried unless we can turn in something extra special. We are way too hot to be continuously getting such crappy grades in college although I think my step-sister's idea for this new project will help us finally get an A. All we have to do is gather some sperm so we can look at it under a microscope and report everything we see. We can't ask our step dad for a sample but we can get one from our sissy younger step brother. He is so submissive to anything we want him to do for us that this extraction for science will be a breeze.

Hi little pervert step-brother. We have something we need from you and if you don't give it to us we won't let you lick our feet anymore and we all know how much you like do that don't we? Sit down and let us stroke your cock so we can collect your sperm load for our science project. All you have to do is sit there and let us do all the work so relax. We're sure you jack yourself off a few times a day anyway in between your work and college at night. You won't mind your two nerdy step sisters using your bodily fluids for science will you? Oh wow! You have a really big dick! We'll take turns stroking it until you give us a huge ejaculation to use for our project.

You're really lucky we don't make you jerk yourself off because you know we would totally make you do it all by yourself. We figured you would give us a big load for our project if we work it out of you ourselves. You can even see our titties and our perfect bubble butts as incentive to give us your huge load. Do our little hands feel good wrapped around your stiffy? I like the way your cock feels in my hand. We'll both put our hands around your hard cock and jerk it off together. We will even kiss for you because you didn't know but I'm adopted so we can do all sorts of dirty things to each other and it isn't even wrong. Look, we'll show you how we French kiss each other. I think we've showed you enough for you to give us your fat hot load now step-brother. Cum in our glass specimen dish so we can examine your sperm now. Oh look it squirted all over us! Hurry let's take it over to the microscope so we can see the sperm swim around. You should put your pants on and get out of our room now. We only needed you for your contribution to our science project which with your hot load, we are sure to get an A.
