My friend outed me to her sister...

This is what happened to me recently. I have a female friend we will call B. She is bi leaning more towards lesbian. She knows I'm bi. She hooked me up with a few of her bi male friends. We have had a few interesting moments. We mess around but not often. We like to hang out and sometimes have fun. We were talking about hanging out the other day. We were both off on the same day and we decided to get together and hangout. We usually sit around in our panties and tees. She text me the night before and said "I have a stupid question?" LOL. I said "ok" she asked if I wanted to suck dick in the morning? I said that is a dumb question lol. I'm always in the mood. She said be there about 8, I said ok. I'm bi but definitely lean more to the gay side. Whenever I go to her house I always pack a "play" bag. Toys, lube, panties etc. I got there right at 8. I told her I was there so she can let me in. She opened the door, I walked in and she asked if I was wearing a thong. I said not yet. She saw I had my bag, she asked if I was going to wear one? I said yes because she already told me to wear one for "J". I went into her bedroom and she followed, she asked me if she can plug me. I said hell yeah lol.i took off my shorts and underwear, I opened up my bag. I handed her the lube and plugs. I have a few lol. I told her to choose, laid on my stomach, I pushed my ass up to give her easier access. She likes playing with a guys ass with her fingers and toys. She put lube on her fingers, she rubbed the lube around my hole teasing me. Then she slipped a finger in me, then a 2nd one n even a third. I was moaning and enjoying it. She stopped, grabbed a plug and started teasing my hole with it. Pushing it in part way and then pulling it out. I was begging for her to use my dido to fuck me with it I was so horned up ugh. She wouldn't use the dido on me. She said we don't have much time "J" would be there shortly. I sighed but I knew I was at least going to suck a big cock soon. She fully inserted the plug, she picked out a blue lace thong for me to wear. We went out to the living room. Not much longer "J" called he was down the street. B told him that we were there just come on in. He opened the door and we both looked up and said hi. He was actually surprised that I was really there. He said he thought she was k**ding. She said I told you that I would have a guy here for you. I was sitting on the couch just seeing how this is going to play out. I was on one of the couch, B was in her recliner. J sat on the other side of the couch. We had a few minutes of small talk. Finally B asked J "Do you want him to suck you cock?" He kinda hesitated a few seconds. I thought for Sue he was going to bail. He said "Yeah, that's why I came here". He told her that he was bi, they have "hooked up" a few times. She finally told him that she wanted to watch us together. He stood up, took off his jeans and underwear. He sat down I got in front of him and knelt down. He was semi hard and I can tell he's has a thick cock and 8in mmm. I put my hand up to cup and massage his balls as I licked his fat head. He immediately started getting hard. I sucked him into mouth and can feel grow. As I was really getting into it, sucking that fat cock and massaging his shaft with my tongue, B's phone rang and she answered it. I was so trying to concentrate on J's cock
It was her sister calling. She asked B what she was doing. B asked "Do you really want to know?" Her sister obviously said yes. B said "I'm watching Joe suck a friends cock lol. I almost died but i was still trying to give a great bj. Her sister asked if she could take a picture and send it? J said no. B's sister kinda knew I was bi but it really didn't sink in until that moment. After J came in my mouth and I swallowed his load. I looked at B and said "seriously?" She "what?" I go."you told your sister?" She started laughing she said she asked and she is jealous lol. J was just sitting there smiling and we chatted some more. B asked if he wanted another bj from her or me? He said he had to go but definitely is interested in more with both of us. We shall see. I really hope so...
