M4F Innocent Girlfriend Tricked into Anal Cheating

It started off as these things normally do, you and your boyfriend were sharing your deepest, darkest fantasies. You told him what you had been burning for, and he did everything he could to make those dreams a reality for you. But now, it was your turn to give him what he wanted, and the only thing he asked for, was to penetrate that tight, puckered hole tucked behind your two juicy cheeks. 

The only problem? Both of you are complete anal virgins, not only has your back cherry not be popped, he has no idea how to properly stretch a virgin ass. 

So of course, you did the only sensible thing any good girlfriend that wants to please her man would do, you sought out advice from someone experienced. You came to me looking for tips, unaware that the best tip you’d get is my thick one pressing deep up your unexplored bowels. 

Pretty straightforward prompt, I want to be your anal mentor. Whether I’m your boyfriends best friend, father, brother, or roommate, I want to give you a lesson that leaves your neglected pussy drooling for more.
