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 family member s member.

You re such a good step-brother helping me out with this. You probably never knew your step-sister was such a slut did you? You re being such a good sport abo
