This is how I had it played out.

Sunday, I was home in my room. When Erin came in and told me about her birthday on Thursday, And because our parents were going away that weekend, leaving on Friday. And as a birthday present, she requested that she wanted a threesome with Eric, my twin brother, and me Friday night. I felt a little awkward thinking about having my brother there, but at the same time, I was turned on about having sex with my sister. Come Wednesday night; my parents went out for dinner. They were leaving me home with just Eric and Erin. My sister called Eric and me into her room. I walk in there; eventually, my brother follows me in. As we walked in, my sister was lying on the bed with just a sports bra and a blanket covering her lower part with something slightly pocking up under the blanket. She then said to us, "do you remember what I said on Sunday on how I wanted to have a threesome Friday night?', 'well I forgot to tell you it's going to be a bisexual threesome birthday gift as in you will be fucking each other as well as me", Eric and I look at each other with nerves red faces.

 My sister then replies, "Now, as an early birthday present, I want us to practice being naked around each other as well as touching one another."

 So she asks us kindly to strip off our clothes. We stood there awkwardly, not knowing what to do and trying to stand our ground against it, but being the oldest, she ended up winning. We found ourselves down to our undies when she told us to drop them, so with a deep breath; we took our underpants off at the same time. Standing naked in front of my sister, she told us to turn and look at each other for a moment. I couldn't help but look down at my brother's cock, which was slowly getting hard, while I was trying to get my cock to stay down.

 As we did that, I slowly looked back at my sister sitting there with about an 8-inch dildo strap-on poking out at us. She told us it was there to help her demonstrate how to stroke each other off. Don't get me wrong. It slowly got my penis to about 60% hard, seeing that dildo between her legs. Then she asked us to reach down and get a feel of touching each other penis, so I placed my hands near my brother's erect cock; it started twitching as I touched it with my fingers, while my brother just gently took hold of my cock as it slowly grew in his hand, with his penis being slightly longer than my, say about 6.5 inches while I was about 6.2.

Erin then asked us to start to slowly stroke each other penis. Here I thought that I wouldn't enjoy it. But unfortunately, you know what a penis is like. They seemed to make their own decisions, and thank's to my brother's hand my penis started to feel about 88% horny. I think a part of me was a little turned on by my sister watching us at the same time she began to stroke her dildo like it was her own penis. As she watched her two brothers stroking each other erect penis, she was slowly demonstrating to us on her dildo how to stroke each other penis; we couldn't help but follow her lead. Erin slowly took off her sports bra. And that sent us both to a 110% erection and told us to start picking the up pace. As She did the same thing with her dildo, it was almost like we were in perfect unison. The feel of touching someone else erect penis while he also touched my penis started to turn me on. And every time one of us starts twitching, she tells us to stop and slow down. Now and again, while we were stroking each other, my sister would be playing with her erect breast and saying she was getting wet thinking about fucking us with her toy. But I only just caught half of what she said, hoping I missed heard what she was saying, hoping she was just teasing. I mean, her penis is heaps longer than ours. 

 After another 5 mins, she eventually told us it was time to release our load. She said we can also play with our own penis now if it helps. So here we are, stroking way. I was horny as hell as my sister encouraged us to keep going, wondering if my brother had the same feeling then me. When just as I thought that, my brother started twitching, and when my sister noticed, she told him to turn to me and shoot his load on my body. I guess with the arousing feeling he was having, he didn't seem to hesitate and just turned to me and shot about a 4 big string load of cum at me with it, landing on my stomach and the next couple of drops landing on my penis. With the arousing feeling I  was also having, I just accepted it. And just started using my own twin brother's cum that was on my dick as lube, which told you what the warm feeling of that cum made my penis go from 100% to about 200% erect; let's say my penis might have grown another 0.2 inches. Especially when I noticed my sister saw what I was doing, she started stroking her dildo even harder, claiming her panties were getting soaked. The feeling of my brother's cum felt so good that when I was ready to upload on my brother's body, the white thick cum came out a lot more powerfully than his, with the first two shots landing at his chest. And I ended up unloading more cum than he did. Eventually, I came to a stop while my sister also slowly started to wind down. I tell you, the way she stroked that long 8-inch purple penis, she probably would have shot a bigger load than all of us.  

And just when we thought it was over, my sister told me to lay on my back on her bed and then got my brother to go all four on top of me in a 69-like position. I think we were so horning as fuck that we just did what she said. She then told my brother to lick his cum off my body. While I did the same thing to him as well, we started at each other stomachs, which I felt a little jealous of because some of my cum dripped off his body onto me, so he was getting twice the taste. Here I was, licking my cum off my brother's body and some how, in the heat of the moment, enjoying the taste. Eventually, Eric started to work towards my penis while I had my cum dripping down from his penis onto my face. Because his penis was dangling down at my face, I just decided to put his whole penis in my mouth and lick the cum off, which made it easy to get most of my cum of his penis, as my penis was twitching from the feeling of Eric licking his cum off my penis.

 Eric's tongue touching the sensitive forehead of my penis (foreskin) made my penis grow again in almost a second. Without warning, my penis just exploded with about another five shoots of cum hitting Eric's face. Which must have woken him up from the horny feeling because he got off the bed with a confused look at what just happened and ran out of the room. Erin stared, laughing. As I lie on the bed, dazed and amazed by the hold thing. My sister then walked over to me, slapping her dildo on my penis (saying, good job, bro). Then she rubbed the dildo into the leftover cum on me and then climbed on the bed, and had her dildo pointing at my face. She didn't have to say anything; I just mentally started licking my cum off her dildo. She then said she could not wait for Friday night. She then got off the bed and started taking her strapon off while I lay there looking up at the ceiling, only to have wet panties hit my face. I just looked other need my sister and could only see her cute butt. I think because of the smell of the wet panties on my face, I fell asleep just as she was getting changed.

The End

 As what happened on Friday night Bisexual threesome and my sister's 8-inch purple penis is up to your own fantasy.
