[M/F/F] Flirtations with my girlfriend’s best friend.. this is pretty mild so far but it’s driving me crazy. I feel like it’s going somewhere. Sorry if it's long without much payoff. | 2016

Before I start this story, I would never cheat on my girlfriend. We’ve been dating for 3 years, lived together for over a year, we’re very much in love and I’m not going to fuck that up. This post is mostly setting the tone for where I think this is going, so updates will follow! Sorry if I’m kinda vanilla, but maybe someone out there will like the story.

My girlfriend Alexis has a good friend who she’s known all her life, named Chrissie. Normally I’m attracted to fit girls like my girlfriend, but there’s something about curvier girls like Chrissie that turns me on. She’s got huge, perfectly round boobs, for starters, and everything else is proportioned just right as well. It also helps that she occasionally gets in this playful flirty mood with me and Alexis doesn’t seem to mind. In fact she eggs her on a bit.

Case in point, a few years ago we were at a party at Chrissie’s house and we’d all had a few shots. The girls were joking around about men and tits, and suddenly Alexis dares her friend to flash us. So I shit you not, Chrissie pulls her shirt and bra down and whips them out completely. Nipples and all. Even without the bra, they still had some lift.

I was stunned and turned beet red and turned away while they started doubling over laughing. I definitely fapped thinking about it later that night. Yeah yeah you probably think I’m a big virgin, but shit.. that was new to me! I'm not a big party guy and I only dated 2 girls before Alexis so this was a big deal to me.

So fast forward a bit, we all went back to our boring little nerdy lives. Shortly after Alexis and I moved in together we had a new years / housewarming party. I was talking to Chrissie in the kitchen when Alexis came up from behind her and lifted Chrisse’s shirt up! She had a bra on but still… holy shit, I was staring right at them again. Maybe it was the tequila speaking but I went waay out of character for a moment. I just fucking went for it and planted my face in between her gigantic tits and motorboated her!
They start cracking the hell up and Alexis fucking high fived me. I love this girl, did I mention that? I couldn't believe what I had just done, holy shit.. that's so unlike me.. And then they noticed the goddamn boner. Why the fuck did I wear my athletic shorts. May as well own it though… shy as I normally am I was just on fire that night and remarked
“My eyes are up here ladies!” and they damn near died laughing. But Chrissie.. her eyes lingered a bit before she looked up and winked at me. I swear she was biting her lip a little.
I definitely fapped to that too.

Life goes on, etc. And now we’re up to this past weekend. This shit only happens when we’re drunk. I promise most of the time we just watch TV and play board games and shit, but that’s not the point of this post right?
So anyway Chrissie was staying over our house to watch a movie marathon. We were sharing this big ass bottle of table wine. I was sitting on the left side of the couch snuggling with Alexis in the middle. At some point I put my arm around Alexi's shoulder, and shortly afterward Chrissie leans over and snuggles up to her also. I felt her arm pressing on my hand all soft and warm and comfy. That is, until I realized it was actually her breast.
Still as oblivious as ever, I thought for sure it was an accident but I liked it there. So I left it. We kept watching the movie, and no matter how anybody moved we always ended up in that position again. At this point I started to think she was doing it on purpose so I kind of moved my hand just a little bit, pretending to stroke Alexis’s arm up and down, feeling Chrissies breast with the back of my hand. Then suddenly, through the fabric of her tshirt(no bra) I felt Chrissie’s semi erect nipple between my fingers.
I stiffened up and stopped breathing for a second and almost but not quite pulled away from her. I left my hand there, frozen in fear as her nipple quickly went fully erect. Shit, what if she wasn’t doing it on purpose? I was grabbing her nipple! No way I can play that off as an accident.. but she didn’t move. She obviously had to feel it though.
I wondered if Alexis knew, more importantly. I felt like I should feel bad.. but I didn’t feel bad. I don’t know why but it felt like she’d be okay with it, and yeah I’m a dumbass for thinking that but I did. So after a minute or so I got bolder and resumed stroking her arm and “accidentally” playing with Chrissie’s nipple in the process. I moved my fingers up and down, stroking it and even giving a little pinch between my knuckles. She hadn't reacted at all, but that made her jump just a tiny bit. I want to believe it's because she was turned on.
Eventually after a few minutes of this I just couldn’t deal with it anymore and stopped. I pulled away and put my arm around Alexis’s waist instead. Chrissie stayed put and neither of the girls reacted.
I felt a little dirty and guilty, now that the excitement was over, and excused myself to use the bathroom. Turned on the fan and jerked off as quietly as I could. When I came back out, the girls were whispering to each other. I was filled with dread but they smiled at me so I left well enough alone. I didn’t dare ask, but they kept exchanging glances throughout the night.

After the movie, Chrissie layed down on the couch while Alexis and I went to bed. I took off my shirt and sat on the edge of the bed. Alexis pulled her shirt and bra off, exposing her perky little tits (I fucking love them BTW). She bent down a little and started kissing my neck.
“Babe, the door’s still open” I said.
She kissed her way down to my chest. “Don’t worry about it, she won’t hear us.”
I started running my hands up and down her back and through her hair. “Babe, really..”
She just shushed me and kissed her way down further to my belly. My eyes were on the door. It was dark in the hallway. Darker than normal.. was the hallway nightlight out? That’s odd, I thought.
She moved to the side and sat next to me on the bed. She started pulling my shorts down and kissed her way down my thigh while cradling my balls in her left hand. She had my attention now!
I could’ve sworn I heard a creak from outside the room. And why was she to the side instead of in front of me? She was leaving a clear line of sight from my dick to the... door.... hm...
Either way I was rock hard (again) and loving every second of this. She had my dick in hand and gave the head a little kiss. She pulled away for a second and smirked.
“Did you start without me tonight hon?” she asked.
“Huh? Oh.. uh.. yeah..” I stammered. Shit, even though had I cleaned up she still tasted it.
“Yeah? Why’s that, honey? Something get you hot?”
“No, you know, just in the mood.”
“Huh” she replied, glancing briefly toward the open door, and licked my cock from base to head. She wrapped her lips around it and started giving me her specialty and I just closed my eyes and laid back and enjoyed the ride. Once I laid down, I took a peek out the door; my nightvision had finally adjusted and there she was; Chrissie was peeking in through the doorway. I don’t think she noticed me watching her, because her eyes were on the blowjob. But she stayed, and she watched. And I let her.
I’m pretty sure we all knew.

Whew! So I got that off my chest… I really was going to post this to r/TIFU but as I started typing it I started to realize what’s going on here… maybe it’s just me but I think they both want a threesome. I really hope I’m not grasping at straws here but I can’t be making this up right? Either way I’m so lucky to have a girlfriend like this and I don’t want to hurt her or act inappropriately or anything. I tried to tell the story as accurately as possible without droning on too long, so again I'm sorry if it was too wordy. Please comment! I'm excited and a little scared and clueless and have no idea what to do next.

Edit: I should add what happened in the morning after this happened; nothing! Nobody acted weird and we just went to the diner for breakfast together, then Chrissie went to work. That's it.

The more I think about it the more I think they're teaming up to tease me.
I think I'm going to just go along with this because if I say anything it'll spoil it. Updates to follow when anything interesting happens..
