Cuckold fantasy relationship part 1

I have a strange fantasy about having a relationship that starts off normal but after a couple of months turns into one that becomes more interesting. I imagine that after the first couple of months of sex every night, my girlfriend gets bored of sex with me and persuades me to try cuckolding. At first I'm all reluctant but with the help of an unofficial counsellor and several weeks of watching cuckold porn with my girlfriend while were having sex I agree to help so that my girlfriend can feel sexually satisfied. From then on my girlfriend would always have a huge cream pie for me to clean up before our daily sex. I thought it wouldn't be so bad eating the cream pie but was disgusted at the taste, my girlfriend said I would just have to get used to it. But after a couple of months of cream pie slurping and sloppy seconds sex my girlfriend became bored again with our sex and with the help of our unofficial councillor persuaded me to get a penis enlargement. unfortunately, after waking up from the surgery, I discovered that it went wrong and my penis was an inch shorter, my girlfriend was very supportive and still gave me my daily sex, but I was upset now that she was probably even more unsatisfied with my penis. I tried talking to her about it, but she seemed to really enjoy sex again with me. but after a couple of months again she became bored and said maybe I could try the penis enlargement operation again and with the help of our Councilor I agreed. but yet again after waking up from the surgery I discovered that yet again the operation hadn't worked and this time I had lost two inches. But yet again my girlfriend was really supportive and said it was much easier for her to give me oral sex now that my penis was only two inches. But at this point sex for me became completely unsatisfying but I was really grateful that my girlfriend would give me oral while I was slurping up my daily cream pies but i still wanted to satisfy her having sex. After a couple more months I was discussing this with her and she said she was more than happy for me to try the penis enlargement surgery again but now I had a discission to make do I go for the enlargement surgery again and try and satisfy my girlfriend with the risk of losing another inch or two or do I try to satisfy her in some other way..................find out in part 2.
