I really want to be part of the most popular sorority on campus. You're probably wondering why I'm telling you this so here goes the reason. In order for me to be accepted into this amazing sorority I have to jerk off a guy and provide proof by collecting a sperm sample as well as take a picture of my hand on the cock. I don't know any guys that I can just ask them to go along with this so now I am telling you what I need. It won't be too weird. All you have to do is lie there and I will do all the work. No one will even know who's cock I have a picture of or who's sperm I have in this little container when I'm through jerking you. As long as you don't tell step-mom and step-dad, this will be just between us. Besides, we're only step-brother and step-sister so it's not like I will have my hand on a real clan member's member.
