"That's good, but don't forget about the middle!" You knew exactly what she was talking about, and began forcing your lips between her cheeks. You had never done this before, and the humiliation of putting your mouth on her asshole drove your cock wild! With no hands to help, it was hard to get in there, but you were determined to please Jessie - partially because you knew Cali would find out about this, and partially because your raging hard-on was controlling your mind and driving you in.
"Use your tongue to get in there! If you do this right, I'll let you have my pussy!" That was all you needed to hear! You drove your tongue between her cheeks, licking her crack, tongue-fucking her asshole. You had no idea what an asshole would taste like, but in your current state it just tasted like horniness and sex!
