Four or five.

You pound away at the Student, making her cum hard in just a few minutes.
She was all warmed up for you though.

Moments later, Ms. Dolore cums as her secret lover works her 'magic' on her pussy.
You warmed her up too though.

"I love her tongue, but I really want to feel yours too," the Teacher says.
"Fine by me," you say, "How should we do this."
"She rides you and the other rides your face," Ms. Stevens says from nearby.

She's standing up near you three, rubbing her pussy quite hard and fast.

You nod and move everyone around. You lay on the couch and the Student mounts your dick. The Teacher sits on your face.

"You'd all better give me a good show- especially if there is no room for me in there."

The two ladies look over at the Dean, knowing that they have to please her to keep themselves around.

The fucking resumes and you start licking the Teacher's well-used pussy.
It's nice and pink for you, gushing with juices.

Unbeknownst to you, Ms. Stevens moves in closer and presses the pair to start kissing. They don't object!

You feel the Student cum on your cock, the combined and continued stimuli being too much for her.

Likewise, the Teacher cums as you eat her pussy. The Alphabet Trick really does work.

During that, you hear what sounds like a muffled orgasm from Ms. Stevens. Speaking of her...

"I'm tired of sharing!"

With surprising strength, she lifts the Student up and off of your dick!
The pair scramble back to the bed.
You get the confused Teacher to move off of your face and see them having fun...

"I'm worn out," Ms. Dolore says, "But that bitch needs some dick. Just wait for the right moment."
