I am very comfortable and relaxed and happy with my sexuality and my sexual tastes. My gf knows I'm bi, love cock, love dressing up etc. She's not only ok with it but has lots of fantasies about guys dressed up sucking each other fucking each other and more.

I love 3somes with my partner and other guys. I've been lucky enough to have had over 30 such experiences with former girlfriends and even my ex wife. My current girlfriend is in her 40's, a very sexy blonde with a great body and a limited but very enjoyable set of past kinky experiences. But she has several very kinky fantasies and I find all of them incredibly erotic. We've made a few come true but the most erotic, daring and n doubt enjoyable ones are yet to be done. 

So far as 3somes and more-sums are concerned, my girlfriend hasn't joined in before but its the main topic of chat when we're horny, and she has her own strong fantasies about watching guys sucking and fucking each other, especially with them in panties stockings and wearing black shin leather high heeled thigh length boots. In particular she found an image online showing 2 very sexy CD's or TV's dressed just as she described, one bent over and the other fucking his arse deep and hard. 

She loves that pic and wants me to recreate it in front of her. I'm all for it. She is very keen to try it at least twice (in case the first time was too much excitement to relax enough to just enjoy it). 

She's keen to make it more centered around her the first time, her being teased tickled licked fingered by two horny guys, preferably as she's tied up - over a table or bed - getting her hornier and hornier, wetter and wetter, until finally being fucked by both one at a time and together. 

She also has introduced a new fantasy scenario to my lexicon, which involves her being fucked by a guy while he is fucked by another guy. She wants me to be the one being fucked first time and then the have me and the other guy swap round. She also wants it done when shes on her back having her pussy fucked and then again on her front having her arse fucked.

Just to make it even hornier, she describe to me how she wants the guy fucking her telling her just what her boyfriend is doing to him. She wants to hear the guy telling her "Your boyfriend is stroking my legs. Now he's running his hands up the cheeks of my arses. Now he's stroking his fingers up and down my crack.. Oh I think hes just started using his tongue on my crack, oh my god he's licking my arsehole, oh he's tonguing my arse, I love it !" 

That would be a huge turn on for her. Then she goes on to describe what he says next "Oh my god, he's is forcing his big hard cock into my arse, and he's fucking my arse deeper and harder, oh his cock feels so good up my arse, no wonder you love it up your arse. Until she hears him say He's cumming in my arse ohhhh" That would be make him cum inside her and her cum all over his cock.

I just think that's one of the horniest and most erotic fantasies I've ever heard and I can't wait to make it com true for her and me
