I'm going to pull the cum out of that +18 young man dick of yours. Step-mommy knows what to do with that hard dick. All that testosterone pumping through your vital, masculine body. Just promise to be a good listener and do as your told. "YES step-mommy I promise to be a good boy and stroke for you. YES step-mommy I promise to use your curves to make my dick thicker and throb." Earn my step-mommy praise and be a good stroker.
