I arrive home from work to my shrunken step-son, I have had a long stressful day so I am so ready to play with him and destress; I am not going to go easy on him.
I strip off, put him inside of a condom on my dildo and ride it anally, my tiny step-son trapped inside of the condom, sliding in and out of my ass. It feels so good feeling my shrunken step-son sliding in and out of my ass. Once I orgasm, I take him out of the dildo and put him inside of my asshole, tensing my ass and squeezing him inside of me until he cums!
Later on, my step-son tells me he needs some advice, he has a date tomorrow when he will be back to full size, and we have only ever done anal play so he is wants to learn more about a women's body. It doesn't matter if he learns when he is still shrunken.
I strip off and show him my body up close and explain the different parts of a woman's vagina. I then let him have a closer look and put him inside of me. I then put him back on the dildo in a condom and ride the dildo in cowgirl and reverse cowgirl until I orgasm. I then take him back out of the condom and back inside of my pussy to see and feel how wet I am after I orgasmed!
