You almost get tricked.

Finally officially dating Rachel, and her seemingly unrestrained, it was the best time you've had since you moved into that house. The sex life between you two was also very active, which had certain limitations because she didn't have a vagina, but you had already gotten used to this different side of a conventional woman in her. Even with the dating already firm, the things you expected Rachel to do eventually but she never did, was ask you to suck her dick or let her fuck your ass. You were willing to accept if she asked, yet she didn't say anything about it.

An event happened on a certain day that showed you still didn't know everything you needed to know about Rachel. On the way home from work, you stopped to buy some supplies at the supermarket that you remembered being out of stock at home. Still in the supermarket, Rachel called out to you from the corner of the isle you were in at the time, and she went to join you after you responded to her call.

You asked Rachel what she was doing there she said she had seen you there and joined you so you could go home together. You finished shopping and went home with Rachel, but you thought she looked weird. The way she walked seemed different, and the way she spoke seemed like there was something wrong.

When you finally got home, the first thing you went to do was put away the groceries, and Rachel now seemed to be unfamiliar with house organization and didn't know where to put things.

After everything was properly in place, Rachel said that she was very horny and that she wanted you. The tone of voice she used in this request was not what you were used to, making you more suspicious.

You said you would go to the bathroom first and then join her, and off you went while the suspicious Rachel went to her room saying she would wait for you there.

Upon entering the bathroom and making sure the door was securely closed, you grabbed your cell phone and called Rachel, and she answered.

"Hello dear, what do you want?" Rachel said

"Where are you Rachel?" you asked

"Ahh, you got worried that I ended up being late getting home and you called me. Don't worry, I'm on my way and it won't take me long to get home." Rachel said

"I knew there was something weird. Listen Rachel, there's a strange woman here who's impersonating you. She tried to make me believe it was you. It must be someone who knows you in some way, because they wore good enough makeup to look just like you." you said

"A woman like me impersonating me at home? Did she make advances on you in any way?" Rachel asked

"She did. She asked me to get into bed with her but I lied that I needed to go to the bathroom first so I called you while she went to your room."

"She will pay me for this. I'm home now, it won't take me 5 minutes to get home." Rachel said and hung up. From the tone of her voice she was furious.

You left the bathroom and went to Rachel's room to confront the imposter. The woman was lying on Rachel's bed, her body covered under the blanket.

"Are you ready dear? Now take off your clothes and come over here." the imposter said

"Who are you?" you asked her

"Don't you recognize your dear girlfriend?" the imposter said.

Before you could answer, you heard the front door of the house open and heavy footsteps of someone running upstairs could be heard. Rachel had arrived and she was really furious.

When Rachel arrived at the door of her room, she faced the woman on her bed and said very angrily "How dare you hit on my boyfriend Trisha?"

The woman laughed and sat on the bed, getting out from under the blanket and showing that she hadn't taken off a single piece of clothing, then said laughing "There's no need to get so mad my dear sister, it was just a test to see if he would know the difference between the two of us, and he didn't fall for my acting at any point, the whole time he suspected that I wasn't you."

"Sister?" you asked, surprised

"Exactly, sister. She's Trisha, my twin sister." Rachel said

"I'm sorry, I didn't know." you said

"It's not your fault and I didn't try to hide it either, but I didn't think I needed to tell until there was a possibility of you guys meeting. But she decided to show up unannounced, and today I was late getting off work." Rachel said

"And how would I test your boyfriend if he knew? That way at least I know he knows how to recognize you even if I'm around and he's faithful to you since he didn't try to advance on me even with giving him multiple chances. You have really chosen a great partner." Trisha said

"Glad your test worked. And what else did you come here to do? Or are you going to say that you came just for that?" Rachel said, calmer now.

"What else could I want to do coming over to my sister's house? I'm on vacation from my job and I've come to spend a few days with you." Trisha said

"Did you come without a suitcase? I didn't see anything with you when we met." you asked

"I arrived very early and nobody was home, so I hid my suitcase in the bushes at the back of the house and went for a walk in the neighborhood to kill the time. When I saw you entering the supermarket I recognized you from the pictures Rachel sent when she told me about you and I put my acting into practice, I was only going to do that until I got to your house, but since Rachel wasn't here I decided to stretch out more a little acting." Trisha said

"As always a joker. We may be physically alike, but our personalities are really different." Rachel said

"But it's not bad. What she did to me just shows that she cares about you." you said to Rachel

"I know, but when you said she hit on you I already knew that it was Trisha who was here and knowing her it was probably not serious, but I couldn't help but feel a little jealous." Rachel said, now looking embarrassed at her overreaction to her sister's prank.

"Now, how about you Trisha? How long do you intend to stay here?" you asked

"If it's not too much trouble, I intend to stay for two weeks." Trisha said

"This means that tomorrow we will have to do more shopping. And as for where you'll sleep..." you said

"She can sleep here in my room, I'll sleep with you in your room." Rachel said, interrupting you.

"Want to keep an eye on your man don't you? No problem. Now I just need to go get my suitcase that's still outside." Trisha said

"Let me get it, it will be easier for me to carry it up here." you said and went downstairs, wondering what two weeks with two Rachels in the house would be like
