This is something that happened back in February when I was staying at Kip's place in Breckenridge.

I didn't write about it at the time because I didn't have the consent of the people involved and I didn't think it was appropriate to ask at the time either.  After posting some bisexual threesome photos last week, I thought maybe I should seek permission to write about it and permission has been granted and I hope you guys enjoy this as much as I did..... Last night Kip and I hosted a wonderful dinner party here in Breckenridge (Colorado).

The guests were; a gay couple from Denver, Kip, Kip's sister and her latest boyfriend. All of us except the new boyfriend have been to Kip's famous "Speedo Only Parties" which he uses me as the excuse to host.

I figured it would get naughty at some point and we'd end up in Kip's hot tub in speedos, or less, later in the evening.  What I wasn't sure of was what combinations there would be.

Kip's sister is always the wild card. I've known her since my first trip to Colorado years ago, she always seems to have a dirt bag boyfriend and she and I have had some naughty nights together, but never just the two of us, always some weird scenario in the wee hours of the morning.

We sat around the dinner table for hours after dinner and the problems of the world were solved. Lots of Trump discussions as always which is fun, as long as everyone has a sense of humor. One conversation that came up later in the evening was the definition of sexuality. Three people at the table identify as being homosexual, the two Denver guys and Kip. It is public knowledge that I am bisexual, Kip's sister said that she is bisexual and she volunteered that her new squeeze (boyfriend) reckons/thinks he is bisexual. The conversation had many tangents and everyone was pretty drunk so the conversation flowed.

At some point late in the evening the two Denver guys asked if they could borrow Kip for some hot tub time... hehehe, we all know what that means.

The only person whose permission was required was Kip's and we had spoken about this on a chairlift earlier that day. The Denver couple consider it a `treat' to have Kip join them every now and then which is cute. I have partaken in sexual activity with the Denver Couple (I'm sure I've written about it) but they have dreams of being the bridesmaids at Kip's sister and my wedding. So, Kip and the Denver Couple left the dinner table to go and have some speedo fun in the hot tub.

Kip's sister, her boyfriend and I were left at the table. The conversation continued to flow just as it had.

The conversation was great but after a while I thought I'd throw a spanner in the works and I asked the boyfriend just how bisexual he was. I felt like during the conversation with the entire compliment of guests, it was Kip's sister who volunteered his bisexuality and I was wondering if that was just a redirect in order not to embarrass the guy.

His response was weak, the more he talked the dumber I thought he was. He rambled about gay and LGBT rights and weird abstract stuff. I had asked him about his bisexuality, not his opinion on gay marriage. The end of his rambling bullshit response was that he appreciated Kip's sisters bisexuality. With a nod of approval from her, he proclaimed that their recent `bisexual threesome', with an extra girl, was the zenith of his sexual experiences.

I could see Kip's sister being exasperated by this moron's response.

Time for me to be quiet, I think I had stoked the fire a little bit and I didn't want to embarrass Kip's sister or her new boyfriend. I was wishing I was in the hot tub with Kip and the Denver Couple getting my cock sucked by one, two or three guys.

Kip's sister had obviously had enough of this guys rambling so she took up the baton and starting the questioning.

"Have you ever made out with a guy?"

No

"Sucked a guys cock?"

No

"Been inside a guy?"

No.

"Had a guy inside you?"

No.

By that stage she was just teasing and it was light hearted.

The conversation moved on.

It was the moron boyfriend who brought up the topic of speedos. He said that Kip's sister had given him, and made him wear them that evening. I let him talk and he said how great they felt, he did say that they felt sexy.

I asked to see them.

He got all shy then, but Kip's sister was egging him on. He was being a pussy so I just stood up, undid my belt, pulled down my jeans revealing my red speedo.

The poor guy didn't have much of a choice so he stood up, kicked his shoes off, undid he belt, undid the button on his jeans, slid down the zipper and slipped his jeans down. I couldn't believe it, he was wearing a pair of AussieBum Portseas!!!

Kip's sister commented that this was the kind of threesome combination that was her favorite. The boyfriend coughed but I said,

"Why not mate? She fulfilled your threesome fantasy, only fair to reciprocate."

My cock was stirring in the front of my speedo and I had to adjust myself and as I did I caught the boyfriends eyes look at my crotch. He was nervous but I think he was up for it.

"Did two girls making out turn you on?" Kip's sister asked. She wasn't expecting an answer, I stood up, taking off my shirt. Standing there in front of the boyfriend wearing nothing but my little red speedos. He hesitated, then with a grumble of "I suppose so" he stood up. I let him initiate it which took for ever. Finally he moved in for his first bisexual kiss.

I took it slow, mostly lips to start, then a little tongue, then more tongue, then a proper kiss and we were sucking face. His shirt came off and we were going at it pretty good, this guy really is bisexual despite my earlier doubts.

Again, I was letting him go at his speed so finally he moved his hands from around my neck and back down to my arse, we were both hard and grinding our cocks together. The boyfriend seemed like he was about to move his hands to the front of my speedo when Kip's sister broke us up.

Neither of us had noticed but she had stripped down to her black Wicked Weasel bikini bottoms, I had seen them before, they are tiny and barely cover anything.

She broke us up to make out with the boyfriend with one of his hands still on my arse, the other hand was presumably on her arse. My face was only inches from theirs as they were making out, to say I was turned on is the understatement of the year. It was a minute ago when I expected the boyfriend to start rubbing the front of my speedo, but it was Kip's sister who started rubbing it. She broke off the kiss and she said to him.

"Watching me eat a girl out was hot right? Would you suck Dave's cock for me?"

Kip's sister was fumbling trying to get my fully erect cock out the leg of my speedos and failing miserably at it so I helped her out. Now I was standing there, in the personal space of a couple, him wearing my favorite speedo of all time, her wearing a Wicked Weasel g-string bikini bottom, me wearing a red speedo with my cock out.

"Come on, I'll help you." She said as she lowered herself to her knees bring him with her.

"Open up...." Her hand was on the base of my cock as she guided it into his mouth.
