It's my job to make sure my stepson and stepdaughter know everything they need to succeed in life, which is why I give them private lessons. As their teacher, I was worried about their lack of focus and basic human anatomy knowledge. Then, I came up with a brilliant idea to teach them and keep them interested: using them as examples. First, I taught them about pussies by showing them both my pussy and my stepdaughter's and letting my stepson touch them. When I realized how horny we all were, I knew I had to teach them about sex as well, so I grabbed my stepson's hard dick and showed my stepdaughter how to suck all his cum out. They both enjoyed my lesson so much that I caught them practicing privately. A stepmother's job is never done, so I decided to keep teaching them about sex. My stepdaughter is going to learn how to ride a dick like never before.
