[MF] My Girlfriend Told Her Sister We Watched Her

So it has been a couple of months since I have posted about Rebekah and I. In that I shared about her submissive side which includes her egging me on to tell her when I think another girl is hot and what I would do to her given the chance. This gets her hot and we often reenact together the fantasy I just shared with her, with her pretending to be the other girl. It is fun and hot as it gives the illusion of cheating without the actual cheating. The apex of this setup was when we went to her house to spend some time away from college and apparently she did not know we were comming or at least that early. We saw her tanning naked out by the pool while Rebekah and I were upstairs looking out the window. I got hard and Rebekah went to her knees and blew me while I told her everything I would do to her sister. This was all I ever thought would happen in regards to this. As we had never shared with any other girl what we had fantasized about together.

​

I was wrong…about a month later after this incident we were sharing a bottle of tequila while camping together to celebrate the start of summer and in her drunkenness she blurted out during a game of truth or dare that she had gone down on me while watching her in response to being asked what was the dirtiest thing we had done together. I had never seen her sister blush like that before. But she was also smiling and seemed to like knowing she had inspired that moment. She even asked how turned on I was and if I really liked what I saw. I was honest in that it was probably one of the hottest things I had done as it was the closest to a threesome with two sisters I would ever get. This made all of us giggle and the game went on getting dirttier as this game does when mixed with alcohol and college aged hormones. Rebekah and I went back to our tent afterwards and fucked like bunnies in heat. We even heard her sister fingering herself from the next tent over which inspired us to round two as I called out her sisters name in Rebekah’s ear making her even wetter than she was the first time.

​

I tried to forget that she knew about this as I figured nothing good could come from her knowing about what she found out. I hoped that one night of fun was all it would be, as I was not in a hurry to ruin things with Rebekah, I love her and I want to see where that will lead. Her sister on the other hand did not share this plan of mine. She would bring it up whenever she thought she could get away with it. This was the case especially if we were out of earshot of anyone or she was wearing a bikini. She loved to almost flash me, where she would begin to show me something but stop before I really saw anything if you understand what I mean. She gave me blue balls more times than I cared to count over the last month. She knew she could turn me on and she loved having that power. About two weeks ago she started to amp things up and began to send me texts where she would ask about my fantasies about her, what about her turned me on, ashe and sometimes in response she would send a pic to tease me.

​

I should have showed Rebekah the texts from the beginning, but I didn’t want to hurt there relationship and to be honest I liked the attention. I am such a sucker for attention from girls I could get in trouble for, it is biggest weakness. She knew her sister was flirting with me but she seemed to think it was just fun as far as I could tell. She loved the after results where I would fuck her silly because I was so turned on because of what she was doing. Last Friday we all went dancing and when her sister grinded on me, letting her body rub all up on mine as we moved to the music she let it happen and at times was the other girl dancing up on the other side of me. She knows I love her but she cant resist being cucked by another girls who wants to hit on me or turn me on in some way and then at the end of the night get fucked stupid by me. It was on the ride home that I finally crossed the line with her sister or at least started to. Within minutes Rebekah fell asleep on one side of me in the back of an Uber ride. As soon as it was for sure she was out, her sister confessed to me that when she felt me get hard against her that it turned her on so much. She told me how wet she was from the night and how she would be fingering herself as soon as we got home. I was just drunk enough to ask her just how wet was she. She took my hand under her mini skirt and placed it on the crotch of her panties. She let out a soft moan that even elicited a knowing smile from our driver. I slid a finger inside her panties wetting my finger and gave it a lick as I pulled it back tasting her. Before we got home she even flashed me her tits to show me just how hard her nipples were. She let me touch them too, the driver enjoyed the show seeing her boobs, everyone was a winner so to speak.

​

As we got home Rebekah opened her eyes again and smiled at me as she looked up at me giving me a kiss telling me how she loved me and what a good boyfriend I was. I felt a bit guilty but I wasn’t sorry. I was too drunk and too horny. We went inside and her sister dismissed herself immediately. Within minutes we could hear her through the walls in her room as we went into Rebekah’s room masturbating. That is when she told me she was awake the entire ride home and that she wanted to see what would happen. Once again she suprised me and we ended up having the hottest sex as we played out where it could have gone with her sister once again calling out her sister’s name the entire time we fucked.

​

Where we crossed the line completely was the next morning, Rebekah had gone to take a shower unbeknownst to me while I was still sleeping. Her sister came in and woke me up with my cock in her mouth. She was greedily sucking my dick like she had no time to waste which I guess we didn’t. She was wearing just her panties as I layed there with her between my legs kneeling over me. Her hand stroked me as her mouth bobbed up and down. Once again I should have stopped it, but after the last month I was wrapped around her finger. I didn’t last more than a few minutes before I exploded into her mouth with her swallowing my cum. That was the first time I looked up and I saw Rebekah in the doorway. I was in shock, I was sure I was about two seconds from being single. Once again she suprised me. Her towel was on the floor and she was fingering herself watching us. She kept fingering herself as she looked at us with lust in her eyes and just whisped loud enough for us to hear between moans, “don’t stop.”

​

I pulled her sister onto her back and this time I was in charge as I slid her panties off and this time I buried my head between her legs and licked her soaking wet cunt as my girlfriend watched playing with herself. I licked her and sucked on her clit until both her and Rebekah had orgasmed. Rebekah came so hard her legs gave out and she sat by the door frame. By this time I was hard again and I looked at Rebekah again and she just nodded as I rolled her sister over onto her hands and knees and positioned myself behind her. I gave her ass a slap as I lined my cock up with her cunt and slowly slid into her until I was all the way inside. I began to fuck her doggystyle hard and fast rocking her body and shaking Rebekah’s bed. Rebekah reached into her panty drawer from her dresser beside her and grabed a dildo fucking herserlf as I fucked her sister. Her pussy felt so good and the moment was so electric after her sister came I pulled out and grabbed the lube from Rebekah’s nightstand and quickly began to take her sister’s ass too. Whereas before she was moaning, she was now moaning and screaming in pleasure until I announced I was close and I pulled out and told Rebekah to kneel before me by the bed and just as she got into postion I gave her the hottest facial I have ever given.

​

Rebekah really is the greatest girlfriend ever. It was pretty much her plan all along I suspect. I don’t know if she really had her sister in mind, but I think she just rolled with it as things developed. I don’t know where this goes from here other than it has happened again (Tuesday night) when she watched us fuck again this time we handcuffed Rebekah with her hands above her head while knelt over a vibrator that was inside her. So that has been my life lately.
