Swollen Balls

I'm Scott 24 and recently I got stung by a bee on my testicles and I had a reaction to the sting. I went to my doctor and he gave a injection and told me the swelling would go down over night, if not come back next day. I got home and my parents were away visiting my grandparents and I was home with my aunt Pauline 47 divorced and staying with us until she got back on her feet. Pauline isn't the brightest person around and failed high school and married young and then he divorced her 20+ years and so she came to her brother. I got home and my sister was staying over her friend place, so it was just me and Pauline. I was walking awkwardly and Pauline noticed and asked what's wrong. Being a lifelong smartass I told blue balls syndrome, instead of getting stung by a bee on the bank of the creek while skinny dipping. Pauline didn't know what blue balls was and I just said I hadn't drained them enough. Why not was her next question and I said I not that good at masturbating myself and didn't have a girlfriend either. To my surprise she believed me and offered to help me, I decided to keep it going and see how far she would go. She offered to masturbate me and having a woman masturbate any woman excited me somewhat. So I agreed and we went to my room and I got naked and Pauline said your balls aren't blue. I just replied that will come by tomorrow unless I drain my balls before then. She sat beside me and started to stroke my cock, I waited for my swollen balls to start hurting but they didn't. But neither did I ejaculate, Pauline decided to undress herself to give something to look at. I still didn't ejaculate, so she started sucking my cock and we went on to fucking. Twice I fucked her and then we slept together that night and in the morning I was disappointed my balls had reduced back to their normal size. Pauline still let me fuck in morning just in case and told me not to let it get that bad again. I said I can't help it sometimes, I can't get myself off or don't have a girlfriend. Pauline said if you have trouble see me and I'll help you, I was going try her every chance we were alone. But she got a job and moved out in to her own place, with her job and her share of her former marriage assets to support her new life. I realized I shouldn't try it too often as I might ruin it for myself. But I did try it on again 2 months after the first time with her, 2 weeks after she moved out. This time I dropped by and told her I was having trouble and was worried about getting blue balls again and she took me to her bed and we fucked. She told me not worry about masturbating just come over. I could fuck her to get relief that way and she enjoyed having sex with me. It'll save her looking for a lover and save my balls also. So that's were we are now, I go and see Pauline twice sometimes three times a week, I don't get a fuck each time, but enough to keep me interested.
