Yes

She gives you a minute or so to breathe, and once your heart rate has gone back down and you have calmed down. She goes back in for round two. She takes both of her hands on either side of the back of your head to get the most amount of grip possible. She puts your head back over her dick, and then she pulls your head in, your throat has somewhat gone back to normal during your break so she has to break the seal again. But once she does she shoves almost all of her dick in, there is only around 5 inches on dick left before you hit her pelvis.

She holds you there for a few seconds and then pushes you back out, she lets you get a few breaths in through your nose. And after a few breaths she goes back in. And pushes she as hard as she can into her crotch. Finally after all this hard work you take every single inch of her throbbing horsecock into your mouth, it is impossible to breathe and you look like a total slut right now. Your throat is bulging to a unremarkable level. She starts thrusting back and fourth using your throat like a cocksleeve for warmth. And you cannot lie, you don't hate the idea of that. She continues to thrust in your throat like this with you getting the air you can when only her massive cockhead is in your mouth.

She continues to thrust in and our over and over for another 30 minutes or so. But then you can feel her cock start to throb more than usual, you can see your teachers eyes roll to the back of her head. Her thrusts start to shorten and her breathing rate rises, you can also feel her heart rate rise through her cock. You can tell she is about to cum. But if you haven't gotten the message she screams:

"Enter, I-I AM ABOUT TO C-C-CUM!!!"

Your oxygen is depleting quickly, and your face is going purple again from the lack of breathing. You want to come up for air but Enter insists otherwise. She keeps your head down, and she thrusts faster and faster. You then feel the floodgates open, and then you feel a thick liquid rush into your throat completely bypassing your mouth. Your Math teacher has bottomed out into you and is dispersing her balls directly into your stomach.

For the next three minutes she continues to unload her massive balls into your stomach. You continue to take her cum on and on. But eventually you can't take it anymore you are about to die from not being able to breathe. So you pull your head up and her cock starts shooting cum in the air and it lands all over your face, body, her stomach, and your bed sheets. After a few seconds of this her cock finally stops cumming. It takes you a while to swallow it all but eventually you swallow it all. But it doesn't go down... It stays hard as a rock, throbbing and twitching for more. You look over at the clock and you see it is only 7:15 AM and you both have to leave at 8:00 to get to school on time.

Once you both notice you still have time for some more lovemaking, but this time she looks you in the eyes and asks:

"Hey, I know you probably aren't ready for this but I want to you know fuck your ass?"

Your mind is still blank from the intense skill fucking you have just received and you are trying to get your braincells working again. Once you have regained your ability to think you ask:

"What did you say I just zoomed out?"

She repeated herself:

"Do you want to continue with me fucking your ass? We have some time left and I am still horny as hell and I can't go into campus with a bulge the size of a jackhammer."

You reply with:

"Yes, but you have to be very careful I have never done this before and I don't want to get hurt."

She nods her head understanding the pressure and nervousness you are most likely feeling. She then lies down on her back with her head on the pillows. She picks you up showing her true sense of strength and then helps you stand over her monster of a horsecock. She then says:

"Start to bend down and slowly move onto my cock, you can go as slow as you want. Just be sure not to push it for pleasure because I don't want to split you in halves, she giggles slightly when she says this but you know she was serious because you could probably pierce a few organs with this big chunk of meat. You nod in understanding and you start to do some sort of sorority squad over the head of her horsecock. You bend your knees a little more to have the sense of pressure on your sphincter from the head of the dick. You try to push a little bit more into your ass but it won't budge. Its just to thick.
