Should you have a threesome with your best friend and your significant other if the significant other requests it?

Well I think this answer is completely specific to how your relationship is and if you happen to be a very jealous man. Now with my situation it is and was a lot of fun and we all enjoyed this very much and have continued this in our bedroom for 15 years! I can also tell you that my girlfriend was not the type to even think about threesomes at the Start of our relationship but I started letting by bestfriends share my girlfriend at a young age and it has always been a big turn on. The reason I started this is because I love seeing my girl that turned on and 2 or even 3 men is what every woman has fantasized about but usually won't admit it but it is. My girlfriend had never watched porn or used sex toys or really been fucked properly. She thought she had but I knew I had a lot of work ahead of me. We met at a Rave and she is a knockout. Me and my friends who are athletes and very attractive men who got a lot of attention from woman our whole lives spotted Layla and a couple of her friends that were nowhere near as hot as Layla is but she was wearing see through white pants that you could see her perfect ass that shined in the blacklists that made her ass just glow. We all took one look and pointed it out to are friends to see before me and my bestfriend approached her. We were rolling she was not but we walked up to her and my friend was peaking so he just plainly told her that he wanted to fuck her in her ass! I spit the drink I had been drinking all over one of her friends face. I looked into her eyes and immediately I saw how much that turned her on and trust me she had never even been fingers up her ass or had her ass eaten or used and toys at this point it was just amazing but to see her excitement and then my friend Brian told her she was coming to my place for a little after party. She smiled big and agreed she wanted to. I figure 100% that means this girl just agreed to getting her ass fucked tonight, right? I was amazed so I told my buddy that I wanted to fuck her ass too so let's see if she is down with a 3some. So we had invited many girls back to my place throughout the night and would have 2 or 3 girls each and would usually pick one out when we got to my house. So I knew it was a Longshot for use both to fuck this girls ass but she might just be a little ass slut and that would explain why her ass was so perfect because there isn't a better exercise to sculpt an ass than being fucked in it. So we get back and I start talking to her and my duck was a semi just thinking about her sucking one of our cocks while the other was fucking her beautiful ass doggy. We small talked and I basically told her that her ass was amazing and I knew what she wanted and not to worry we were planning to give it to her any way or every way she wanted it. She blushed and was kind of embarrassed because there were like 15 people we had brought back plus like 7 of our friends all strangers to her except Brian who had got the greenlight to fuck her ass already. We all started telling her that her ass was meant to be fucked and we all agreed that we would eat this girls ass all night and she could pull that ass out and we would lube her up good and wanted to squeeze and slap it around. She started to get nervous especially since her ass was a tight little virgin ass. I took her by her hand and took her to the bathroom where I pulled down her pants spun her around and dropped to my knees and ate her ass good. I grabbed some lube and squirted it all up on her ass it was cherry flavored. I kept eating her ass until she cried out fuck her ass. I stood up and had a handful of her hair when the bathroom door sprung open and Brian smiling huge said God Damn you started without me? She turned and looked at him and said I want to suck your dick while he fucks my ass. She said not to worry she wanted him to fuck her ass too. We both told her she was going to take our hard dicks and we said we were going to dp her tonight and then she said she wanted us both to cum on her face. So he sat on the toilet she was on all 4's sucking his cock and I slapped her ass around and told her to spread her ass for me and tell me to fuck her ass and she did right away. The view from the back was too good and we both made sure and took viagra earlier so we were rolling and both had very hard cocks for this what we thought was an ass slut but her ass hadn't even been fingered before this night. We have above average cocks too 8 and 9 inches and viagra fueled so it wasn't going to be broken in over time with fingers and butt plugs or beads her ass was going to get hard cocks right out the gate. So I rubbed my cock up and down her pussy and ass and kept lubbing her up and squeezing that lube into her ass until I knew I could start putting the head of my cock into her ass. My dick head slid into her ass without too much of a fight and I stopped there. She gasped for air and Brian just grabbed her hair and started deep throating her and she was drooling and gagging as he made her take every inch down her throat. Then I told her to tell me to fuck her ass and she tried but couldn't with all of his cock down her throat and Brian looked up at me and said fuck her ass now! So I grabbed her by her hips and ass and pulled her to me as I forced it in almost all the way then she moaned with his cock stuffing her mouth and throat and was gagging and moaning loudly now. I started to fuck her ass deep and steady while I slapped her ass and started talking to her like a little ass slut. The more I talked and he harder I fucked her ass the more her ass just opened up and she was really turned on. Brian would take his cock out her mouth and cock slap her face and tell her that he was going next and that we were both going to cum all over her beautiful face. I felt like I could cum at anytime so I slowed it down and she immediately begged me not to stop and trusted back into my cock trying to make me keep fucking her ass so I slowly backed out and told Brian it was his turn and we swapped spots and quickly stuffed her mouth without washing off my cock at all and it actually turned her on even more. I told Brian to put more lube up in her ass before he started and then I just force fed her throat until she was gagging on it and he slid his cock right into her ass like it was nothing and again she gasped as he went deep. We fucked her in her ass for probably an hour or more and took turns at least one or 2 more times fucking her perfect ass before we both jerked off all over her face and cockslapped her face making her suck both of us dry. I wish I had videoed her first time anal threesome especially after we both drowned her was huge cum shots. She looked so amazing and told us that she had came like 5 times during that hour and a half. So after that being her 1st time she obviously enjoyed it and we ended up gangbanging her with like 7 of my friends at that year's Superbowl party that we hosted. Guys only NO women were allowed just so my friends girlfriends wouldn't stop us from giving it to her. It was planned and she has outfits and toys and all kinds of goodies to make this an amazing Super Bowl and even better my hometown team played and won the game that year. This was such a success that it became a yearly party we threw. So for me this sexlife became our hobby and we bought so many sex toys and endless stripper outfits and lube and batteries abd tripods and video cameras and we took pics and videos of all our fun nights. She was a bartender too so she would bring home men sometimes and we did all kinds of kinky shit to keep it exciting and new. LAYLA loved the attention and loved being the center of attention and gladly did all the freaky shit that my buddies girls didn't do so she loved being our sexy cumdumpster and will always be out cumdumpster.
