Once again begin with her face visible and already with the cock inside of her pussy as she's slowly riding it...She's looking down and texting on her phone and then, after a few seconds, she looks up and say “hello” and welcome you to “advanced sex class 101: how to hold your cum, part 2”. She once again explain that this is an advanced sex-ed class and it will teach you how to control your orgasms so that you don’t cum too quickly during sex.

Once again begin with her face visible and already with the cock inside of her pussy as she's slowly riding it...She's looking down and texting on her phone and then, after a few seconds, she looks up and say “hello” and welcome you to “advanced sex class 101: how to hold your cum, part 2”. She once again explain that this is an advanced sex-ed class and it will teach you how to control your orgasms so that you don’t cum too quickly during sex. She explain to you that throughout your time here, she will be taking notes and evaluating how good your cock is at lasting before cumming. She also explain that she will have you stroke your cock at various speeds in order to build your stamina so that you can eventually last as long as the cock she currently have inside of her.

After explaining the class, she puts down your phone, put on some glasses and then grab a small note pad and pencil.
She tell you to take your cock out and to begin stroking it while looking at her pussy. She tells you to stroke your cock with the same slow speed as she is riding. She takes notes and comment as she is slowly riding.

After a few minutes of slowly riding on the cock, she stops riding but tell you to continue stroking your cock while she keep writing down notes.

She then put the note pad and pencil down and tell you that she's going to do something different this time around. She explain to you that she's going to play with the balls of the cock she is sitting on and she want you to do the same too. She's just sit on the cock while playing with the balls and directing you to do the same with your balls (rubbing, squeezing, massaging, etc.).

After this exercise she start to ride again...at this point she tells you that you've held off enough on taking it slow today and it's time for you both to have some fun...She tells you she is going to take some time to enjoy herself because she is really horny and really want to cum so you should stroke your cock until you cum too.

She leans back her head and ride as aggressively as she can until she cum and the cock she's riding cums inside of her.

Once she and the cock cum, she return to slowly riding, ask you if you came, pull the cock outside of her pussy and show you the cum inside of her, put the cock back inside of her pussy, and once again pick up the notepad and pencil and begin grading you.
She tells you what you did well and what you need to improve on, and that she hope to see you again for session 3.
