Time to fuck Katie's ass

"I love you too, Jackie." answered Katie. "And I think it's time to fuck Katie's ass."

"Do you...do you really want it?" Jackie was surprised.

"Yes, I would love to be fucked by you, dear."

"But, does it mean that you'll fuck my ass later? You've said that you've fucked everyone who'd fucked you." asked Jackie.

"Don't worry, sis, I'll fuck your ass anyway." smiled Katie.

Katie put her bathrobe on the floor and went down to doggy-style position. "I'm all yours." said she.

There was no need to ask Jackie twice. She lowered behind Katie and aimed her big cock to Katie's ass.

Katie lubricated herself with her saliva (and Jackie's sperm) and bend her back down.

Jackie put her cock to Katie's hot ring and pressed a little. Although she was proud of size of her cock (and she had s reason for it) it slided into her older sister's ass.

Katie moaned. It was the biggest cock she ever had in her live. She tried to relax her ass as much as possible but she felt it stretching her. She was thankful to her passion for different toys she was used. Katie used even larger dildos in her ass but only after long foreplay with smaller ones.

Fortunately, the unpleasant feeling wasn't last long. It disappeared several seconds after Jackie entered her rear end. And it was... perfect. Katie had used a lot of toys of different length, thickness, texture and shape but they were nothing in compare with hot, living flesh!

Katie was overcame by the pleasure and didn't realize that Jackie is talking to her.

"Are you OK, Katie? Katie?" Jackie was asking. "Should I stop?"

"No!" moaned Katie. "Don't stop, please!"

"Oh! So you like it." smiled Jackie.

"I adore you! I worship you, Jackie! Just don't stop!"

"OK, honey." giggled Jackie. "It seems that you are real butt-slut!"

"Whatever you want." moaned Katie.

"About that girlfriend of yours, Melissa. Was she your first girlfriend?"

"No, oh!" whispered Katie. "She is my last. She's too young to be my first."

"How did you meet with your first ... you know, who accepted you as you are? How old was you?" asked Jackie moving her hips with an experience which could be only earned by everyday fucking of Suzie's ass. Katie was envying her now.

"I was dumped by my boyfriend... I felt so lonely..." said Katie with pauses. "She was comforting me, she knew about it... And it had happened..."

"And who was that?" asked Jackie.

Katie moaned instead of answer. Her dick was hard as rock, Jackie's balls were swinging and hitting Katie's ones.

"Who was that? Do I know her?" Jackie was curious.

"You know her... It's... It's Mommy" confessed Katie.

"What? Did you... did you fuck our mother?" Jackie stopped.

Being aroused to the edge Katie couldn't allow it to stop. She started moving back and forward, sliding over Jackie's cock.

It was enough for Jackie. Fucking a gorgeous woman, fucking the own sister and knowing that her sister fucked their mother... And that perfect ass is sliding over her cock... Jackie tried to delay her cumming. And she succeed. For two seconds. And after it she cum her huge load inside Katie's ass. Her cock was pulsing, shooting more and more sperm.

That was enough for Katie also. Without any preliminary feeling her cock swing and shoot hot stream on the bathrobe. Some of it was left on Katie's long hair, some on her hands. She have lost strength in her arms and fall down right into sperm covered bathrobe.

Jackie's cock slided out of Katie's ass. Hypnotized, Jackie was looking on her sperm flowing down Katie's crotch and balls. She lied next to Katie.

"You are great, Katie." said she.

"I love you, Jackie." said Katie after several minutes. "I adore you. I want you to fuck me as often as you can." mumbled she.
