Anal intercourse.

"Not now." said Katie. "It's time to DO something good." She pointed on her again erected cock.

Suzie gently pushed Katie on her back and stood over her with her legs wide. She aimed Katie cock in her ass and started slowly going down. It took several seconds for Suzie to relax and let cock-head in. After it she moved down like it was nothing sliding inside of her. Katie was impressed. No one could take her cock in the ass so fast. Even Jane or Melissa; after weeks of daily sex they still needed more time to get used to Katie's rod. Not much Katie's girlfriends could take her cock in vagina so fast.

Then Katie realized that Jackie was in Suzie not so long ago.

"You are good in..." started Katie but Suzie stopped moving down, leaving about 2 inches of Katie not inside. She moaned quietly and her face expression said to Katie that it is not a pleasure moan.

"Are you OK, Suzie?"

"Yes, I'm fine." said Suzie in a second. "You just a bit bigger than Jackie and I forgot to move slower. Give me a minute, I'll get use to it."

She started to move up and down, each time move a bit closer to Katie's pubis. When it was only one inch to the full penetration, she started to move her hips and body around, trying to let Katie further.

Finally she sat on Katie.

"Oh, it's wonderful! A bit hard, but wonderful! I love it!" said she happily.

"Don't forget that you love Jackie too." smiled Katie.

"I will never." answered Suzie and started to move. At the beginning she moved only half of the inch up and down. Then one, one and a half, two. Katie wasn't be aroused to cum fast so she fully enjoyed the process.

When Suzie started to take Katie's cock out and slide all the way down Katie said - "You are very good in it."

"I practice a lot." giggled Suzie.

"Every day?"

"Twice per day!" smiled Suzie. "Jackie is a really horny girl!"

"Wow! It's hard to believe."

"You are right. I usually took it in mouth. Jackie had be able to fit it in me only month and a half ago. And we didn't do it every day for the first week."

"But then you did..."

"Yes. Jackie is very enjoying it. Today she came three times there. And she would cum more if errr..."

"If she wouldn't go to do own sister and mother." said Katie with a smile.

"Oh... oh..." Suzie stopped moving and froze still. She was really tensed.

"What? Are you OK?" asked Katie, worrying a bit.

"Y.. Yes, I'm OK." answered Suzie after several seconds. "I've imagined what you've said and it is so kinky... I hardly hold myself from cumming." finished she and slid down on Katie's shaft.

"Why to hold?"

"I wanted to show you something first."

Suzie moved herself the halfway along Katie's cock and moved toward Katie's face. Then she started to move down again while not being above Katie's pubis. She was looking very concentrated. Katie wondered, what exactly Suzie wanted to show and the she saw it.

Belly bulge! Katie saw her cock moving inside Suzie. The bulge was small, as Suzie wasn't relaxed, but understanding that her cock is huge and it is completely inside Suzie aroused Katie like nothing else. The one thing is to know that your cock is deep inside someone's pussy or ass (or throat) and it is not the same as see it with own eyes.

Suzie didn't do it long, soon she moved back and continued her ride.

"Wow, Suzie! It was really impressive!" said Katie.

"Do you like it?"

"I would like to see it again several times. Or several tens of times. And it's really impressive that you've learned it in one month."

"Oh, thank you."

"I think it's time to cum." said Katie. "No, no, don't move faster, relax and imagine."

"Imagine what?" asked Suzie, sitting on Katie.

"You are sitting on the same cock that I've put in my own mother about two hours ago. In all her holes. And in my own sister mouth. And Jackie, after fucking you, went to fuck all holes of her own sister. And now she, I suppose, have fucked her own mother in all her holes at least once. Imagine that Jackie's sperm is dripping from all Jane's holes. Imagine Jane's face in the sperm of her daughter. Of two her daughters..."

"O-O-O-o-o-o!" the hot fluid was ejected from Suzie's cock, falling on Katie's tits, face and (what Katie liked more) lips. Suzie ass tighten and squeezed Katie's cock, forcing her to cum as well. Suzie bend forward to Katie and found Katie's mouth with her lips...

"I adore you." said Suzie after she catch the breath. "I never thought that I can cum so hard with just imagination."

"Hmm? And what about this?" asked Katie, moving her cock a bit.

"Oh! Yes, with it also. It's fit me so good that I've almost forgotten about it."

"If it fits so good that you're not noticing it then I'll be shoving it in you unexpectedly. While you sleep or eat, for example."

"I would love that."

...

"Hmmm, do you want to check Jane and Jackie? Do you want to try your first pussy?" asked Katie after a while.
