I got a text from my aunt Helena asking me to stop by her house after school. i loved spending time with my aunt Helena mainly because she was so hot and i had a huge crush on her. i texted her back and told her id be there, once school got out i went straight to her house. i let myself in and found her in the kitchen. we made small talk and then she started telling me about the problems her and my uncle were having. she said they had been trying to get pregnant for a while but they hadnt had any luck. they saw a doctor and he told them it was because my uncle had a low sperm count. they really wanted a baby but my uncle wanted to be his baby so adoption was out. the artificial insemination might work but it was to expense for them to afford. she was really worried she thought there marriage might be coming to and end unless i could help.i asked her how i could help and before she answered she got a really weird look on her face and i could tell she was uncomfortable. she said the baby need to look like my uncle and since my dad and uncle were brothers i looked just like them. so with that in mind maybe i could be a secret sperm donor? i got really panicked and said i didn't know i could do that, she started to beg and said it was the only way to save her marriage. i was still super uncomfortable but i agreed to help, i asked her what i needed to do. she got a huge smile on her face and thanked me. she said the doctor would need to test my sperm to make sure my count was high, so she was going to need a sample from me. she gave me a sample cup, lube, a towel and told me to go to her bedroom and finish in the cup. i was still freaked but i agreed and headed to her room. after a couple minutes of trying i just couldn't focus, so i covered up and called out to my aunt. she came in and i explained the problem, she got really panicked again and said she needed this to work. i asked what i should do and then she just said what if she help? i asked what she meant, she told me to just lay back and relax and she would do all the work. she sensually stroked me off into that cup and it felt great. once we finished she told me to get dressed and she would take the sample to the doctor. she reminded me that this was our secret and i would hear from her soon for the next step! It had been a while since my aunt asked me to be her sperm donor so i was starting to think that she didn't want me to do it anymore. so i was really surprised and happy when i got a text from asking me to come over once i got out of school! when i got to her house i knew my uncle was still at work since he was always working. i found Helena and we chatted for a minute then she told me that my sperm was tested and my count was high and today she was ovulating. i asked her if that meant we were heading to the clinic and she told me no. it was to expensive at the clinic and my uncle would find out. i asked her how we were going to get her pregnant then, she smiled and told me the old fashion way. she told me to follow her and she led me to her bedroom. once she closed the door i told her i was really nervisou about this, she just told me to relax. we were not going to do more then we had to, i would take my clothes off and she would just take her bottoms off. once i was undressed she told me to lay on the bed then she straddled me and lowered herself on to my hard cock! she said this was technically this was sex but we werent doing it for pleasure and with that she started riding me. after a few minutes she told me i was bigger then my uncle and im pretty sure she had a few orgasms before i came in her. she told me to come back tomorrow after a school since she still would be ovulating then as well! As soon as i got out of school i went straight to my aunts house like she asked me to. once i got there i met my aunt Helena in the kitchen. since i got to fuck her yesterday it was all i could think about, as soon as we started talking in the kitchen i started undressing her with my eyes! she told me that what we were doing was really hard for her and this was the last day she would be ovulating for a month so we really need to make sure i got her pregnant so she would have to cheat on her uncle with me anymore. i told her i understood and i would try my best, she thanked me but then said she had an idea to make sure i gave it my all.i asked what she meant and she said that she wanted to make sure i was extra stimulated so we needed to stop treating this like a clinical operation and act like 2 lovers. i asked her what that would be like and she told me to follow her to the bedroom and she would show me! when we got to her room she shut the door and then told me to strip naked, i did and while standing there my dick rick hard and pointing straight at Helena she told me in a sexy voice to lay down on her bed. once i was on the bed she slowly stripped naked and crawled on to the bed between my legs. she said it was time to make sure i was extra stimulated and with that she started sucking my dick. get a blowjob from my sexy aunt was pretty amazing but when she stopped and told me it was time to fuck her i nearly came right then and there. once we started fucking it didn't take me long to fill my aunt up with my cum. once we came down for the orgasmic high she told me would have to do this several more times today before my uncle got home and we did!
