Son is a little worried because no matter how much he jerks off he keeps getting hard at the worst time and he cums like a river. He goes to his Mom for help, she says she will ask Aunt Susan who is a doctor what she thinks. When Mom gets back from the Doctor's office she tells her Son he has to cum in a cup several times a day and have it measured to see how much cum hes producing! The one catch is he needs a helper and since there is no one else around a reluctant Mom has to help! Mom is in a hurry this morning trying to leave for work but she still needs to take her son's sample. she figures she needs to help stimulate him fast so she can milk his cock. she shows her son her nice thick juicy ass and even lets him play with it just a little! once she has him nice a hard she drains his balls into a measuring cup! Mom has to hurry off to work again but still needs to take her sons sample. The last time she did it she got lube all over her work clothes so this time shes going to collect his sample in just her bra and panties. My Aunt Kimmie who is a nurse stops by to check on me and my Mom! Together Mom and Aunt Kimmie drain my cock for a sample! Today Mom comes in to get my semen sample, and this time she decides to help stimulate me by sucking my dick until I make a big load for her. I love the way my mom works my big cock. Mom wakes me up with a blowjob, i asked whats going on and she says she wanted to get my sample right away. i could tell she was really turned sucking my dick and shes ends up letting me fuck her! yep that's right after all this time she finally lets me fuck her! at the end to finish it all off i also creampie her as well!!
