Surprise Visit

It had gotten to the point that whenever I came over to Elizabeth's house, I didn't even knock, I just walked in. Sometimes I yelled, but usually I snuck in to scare her. I'd usually walk in and she was on he couch, so I'd quietly go forward and grab her boobs from behind. This was a fast and easy way for us to get right into sex.

One day, I decided to hide by her house until her roommates left so I could come in instantly. Elizabeth usually didn't tell me to come over for a little while and I wanted to give her an early surprise. I didn't really know what Elizabeth did before I got there, so curiosity overcame me as I snuck in.

I walked in and didn't hear the TV as I usually do. I thought she might be in another room, so I went around, quietly of course.

I checked the bathroom and her room, but she wasn't there. I decided to to to Elena's room to see if she knew. I went over and she wasn't there.

I was getting upset now, and since I saw both her roommates leave, I checked their rooms. I had never even looked into their rooms, but often wished Elizabeth would let me fuck her on her roommates bed. I got up to the door, which was slightly open, and looked through. I was simply astounded at my findings.

There, on the bed, was Elizabeth and Elena naked, making out. Elena was on top of her sister, both seeming deep in lust with each other. Elizabeth had her hand deep into her sister's pussy, hand fucking her as they kissed.

Elena removed her lips from her sister, which got me scared that they might get up and see me. But instead, she went down to suckle on her sister's breast. She moaned loudly and I took the long moment of moaning to undo my pants. I had a raging boner and really needed to get off.

In the short time I was looking down, they finished making out and I saw then siting on the bed looking into each other's eyes.

"It's my turn this time," said Elena as Elizabeth gave her a pouty face. It must have been joking because she smiled and got onto her knees. At this moment I had seen a gesture of love I had never seen. Elena went onto her knees and grabbed her sister's ass, spreading the cheeks. She kissed up and down and all over her asshole and he large, firm ass cheeks. She stopped only for a moment, and then she proceeded to dip her tongue into Elizabeth's asshole.

"Oh Elena!" She yelled and startled me. I was still unseen outside the door as the two sisters commuted incest as Elizabeth's ass was being eaten out. Elena seemed to be skilled, making me think they did this quite often. Her tongue moved all around Elizabeth's ass, going in and out of Elena's mouth and in and around Elizabeth's asshole. Elena stopped and poked the hole lightly with her index finger. She slowly started putting it in farther, until it was going all the way in her ass.

She finger fucked her sister for a little longer, and I was getting close to cumming. I really wanted to release it, but didn't know where. I decided just to run down stairs and go out the back quietly and I came I the yard. I ran back upstairs and didn't miss much.

Elena must have gone to get a dildo while I was away, for she was putting the strap-on around her waist when I returned. This must be what Elena was talking about when I fucked her ass.

Elena finally got it on, and lined it up with Elizabeth's pussy. She grasped onto her ass cheeks to stabilize, then pushed forward and fucked Elizabeth, both on their knees.

"E-lena," she said while panting, "We should, invite Austin over, to do this with us."

"But this is our sister bonding time," Elena replied.

Elizabeth was too busy get pumped in the pussy to answer. I was mesmerized by her tits bouncing as she was fucked by her baby sister. Elizabeth moaned as her sister made her cum on their roommate's bed and around the fake cock.

Elena proceeded to pull out after Elizabeth came. Elizabeth got off her knees and turned around. She put her head down and grabbed the dildo.

"Ready for your juices?" Elena asked her. Elizabeth nodded and suck her own cum off of the fake dick around her sisters waist. She slurped and looked into her sisters eyes until all of her juices were off of the dildo. I got ready to move as this happened assuming it was over, but then it continued.

Elizabeth went back to her knees and Elena readjusted the strap-on. She then lined the cock up to Elizabeth's ass. This is the moment I realized that these sisters really had a thing for getting fucked in the ass. Elizabeth had a much better one, but Elena seemed to take a dick in her ass better, and I was tighter so it was better to fuck.

Elena spit on her hand and rubbed it along the already lubricated cock. After moistening it, she spit right above Elizabeth's asshole, and rubbed it all over, adding extra lubrication. This proves how often they must do this.

She slid the dick into the ass, and wasted no time fucking hard. Elizabeth's ass rippled as it was fucked hard by a young girl. She sank her head into a pillow and used it to muffle her scream as she loved the pain being brought into her ass.

"Cum for me Liz, one last orgasm until Austin comes here."

With that Elizabeth released all the cum she had left in her and soaked the sheets at the end of her roommates bed.

"Good thing we have to clean the sheets for them today or we'd be so dead," Elena joked as she kissed her sister. "Time to clean to dick."

Elizabeth hurried to flip over and get a hand on the cock. It was so dirty, yet arousing, to see her suck her own ass off of a dick. She took her time this time to suck it all off slowly. When she finished, Elena took the dick off and the girls to dressed. I was to busy watching that I didn't notice how hard I was, but I decided not to waste anything I had yet since I would be fucking Elizabeth in a little bit.

I saw the girls start to get the sheets off of the bed and get ready to wash them. This was my cue to get the hell out of their before I was caught. As I got outside and got away from the house, I received a text from Elizabeth to come over. It sucks I had to wait so I seemed like I was at home.
