Please help me bulls I need your opinion

Myself and my wife started using toys a few months ago she never really liked them much she would just rub them up and down her clit she always said I felt better and warm that the dildo felt fake we are married four years now and have two kids she was a virgin when we got married I'm the only guy she has ever slept with and she comes from an old fashioned religious family marry one guy and no sex out of marriage if you know what I mean we where married for a year and a half before we watched any porn we where apart for a week and I was talking to her on the phone it was about midnight she was in bed and I asked her what was her naughty fantasies and she told me she had none and asked me what was mine I told her I'd love for some guy to fuck her in the ass while she was untop of my cock and she said really would you like that and I said well the thought of it turns me on she never really said much about it so I said come on tell me your fantasy and she said I have none but would you like to watch some porn something and that's when porn got introduced into our marriage we watched it just a few times after that noting serious it's just with the last few months things is getting more serious it's kinda a routine thing now her dressing up on the weekends after a night out or maybe a good few glasses of wine at home she gets on her heels , fishnet body stockings or corsets or whatever and watch porn she gives the greatest blow job ever now with quite a lot of practice in four years I can always make her cum I've always felt big on her or inside her if you know what I mean there wasn't much room in her vagina when my penis was in there she was really tight and would often have multiple orgasms during sex but lately I've noticed that there's a little more room in her vagina it feels a little like my penis is a little shade skinny for the hole I'm not stretching it any more and during sex she grabs me by the ass with both hands and pulls me into her hard and when she is on top of me I can feel her pushing up and down me harder like she needs more but she still have orgasms but she has to try a little harder sometimes but I don't mind this the sex is still great we where at the mall carpark a few weeks ago and she has a great ass in jeans I was in the car she was walking across the car park and two black guys honk the horn as she walked passed there car and I said it to her and she said I know black guys always gives me a hard time and laughed it of and I simply replied would you blame them look at that sexy body so to make a long story short that weekend we where watching porn she just came home from the club she was kinda drunk we where watching porn but it was all white people on the video's I could tell she was so bored then I put on a video of a similar looking blonde lady like herself being fucked by a BBC when she seen that she said oh baby please leave this video on I love videos with blonde girls but I was thinking the girls on the all white porn videos had blonde her but I never said it to her so next weekend I went to the store and picked up a video of blacks on blondes I came home that evening she was in one of her naughty outfits and she had quite a few glasses of wine on her I put on the video while she lied on her back watching it I could tell she really liked it there was a black guy pounding a blonde girl with a huge cock she was rubbing her clit moaning and she suddenly slipped up and said oh imagine that in my pussy I said what did you say because she is not the kind to ever say anything like that and she said oh no baby I meant your cock but I know what she meant I said no baby your ok imagine that huge cock inside your tight pussy I handed her a black veined dildo the one in the picture above and while she watch that video of the bull pounding the blonde she fucked her pussy to a really hard orgasm moaning and actually squealing like I never heard her moan before while I was telling her imagine that huge cock in her pussy she was so horny she ate my cock and fucked me so hard then this continued for a number of weeks last month she was on top me watching porn while she was fucking me she said to me let's close our eyes and imagine it was the first time we met each other and we are having sex for the first time so I said ok baby I played along with her for a few minutes then I said it's my turn she said ok I said look at that video the girl in the porn video was on top of the huge cock I said now close your eyes and imagine that's you fucking that black cock she said ok she closed her eyes and I said to her do you like that black cock in your pussy she pushed back on my cock and she yelled oh I love that black cock in my pussy and she kept on repeating it ontil we both came really hard then a few weeks ago I went to the sex store and bought her a much bigger ticker dildo than her black one and much bigger than me her new dildo has a suction cup and it's alot more realistic that night I introduced it to her she said oh it's so realistic I started to fuck her pussy with it and she came really quick then I showed her how the suction cup works she stuck it to a chair and started to fuck it the grit of it is much ticker than me and she never had anything as tick as it as far as I know anyway she fucked up and down it with real long strokes that wouldn't be possible with my penis she slapped her fat ass and she actually started to squeeze her own ass and I mean really hard squeezing her nails into her ass cheeks ass she moaned to and orgasm she had an orgasm in about 20 seconds on this new dildo she really likes it and she have used it a few times now fucking in different positions I had her doggystyle it while she was sucking my cock at the same time and any time we are having sex now and if I tell her get one of her toys it's the big suction cup one she brings to bed and then last week the most weirdest and disappointing thing happened we where watching interracial porn the only type that used to turn her on which is BBC pounding blondes that looked like herself but anyway we where in bed I put on an interracial video and she said oh you always puts on interracial porn she said I don't like it so I just turned it off the sex wasnt as exciting as usual and that was over a week ago I'm actually away on business since then so we had no sex since and she went to her mum's with the kids just on till I get home I don't know what went wrong maybe she hadn't got alcohol in her system because that's when she gets real nasty but then again I got out of the shower about two months ago it was daytime she was in bed naked watching interracial porn while she was waiting on me I never asked her to put it on it was in the middle of the day she also often asked me about black guys ever before I showed her interracial porn is it really true that there really like that which she meant huge penis and I replied yes so here I am now puzzled after all the signs did she mean it or not what do you guys think about everything I told you about my wife opi IMAG0102.jpg IMAG0099_BURST001.jpg IMAG0097.jpg IMAG0094~2.jpg
