Pranking my Aunt

My aunt by marriage 53 and now widowed, I've never seen her smile that I can remember. I'm 26 and bit of a prankster and at a family wedding a cousin's wedding, I my mother and aunt were staying with my mother's brother the bride's father, and I had the attic my mother her own room as did my aunt. My father departed years ago and hasn't kept in touch. My mother had 2 brothers the older of them died due to covid and was married to my aunt. They had one son who died on active service. Anyway, I was staying put at my uncle's place while my mother joined him and wife visiting their old friends of the family. I sounded boring to me and so I stayed behind, my aunt also stayed behind because she didn't know them or something. My aunt liked a sherry or two and my uncle told she could finish the bottle he had. I heard him tell my mother it would get rid of it; the bottle was kept for the previous local minister, and he had transferred. There was about an inch and a half left in the bottle, so me being me topped it up a bit with vodka by 2 inches. It was also imported vodka a lot strong than the local made vodka. I done while my aunt was napping, after he got up, she had a sherry. That was her usual thing usually just the one rarely more. As the rest of the family weren't due back till the following afternoon. I was going out for some fun; I left my aunt drinking the sherry. While was out there was a bad thunderstorm and everything seemed to shut down, as there were more storms coming. So, I returned to my uncles and found my aunt passed out on the lounge and sherry bottle empty. I thought it funny at first and decided to prank her even more. I got her to her bed and undid her top and unclipped her bra front clips and with a bit of baby oil she had on bedside table on her fingers I rubbed one hand around her breasts and put the other inside her panties and rub the baby into her pubic hair. That's how I left her and would her reaction in the morning, that was the plan anyway. But as said before more storms coming and one let go a thunderclap right over the top of the house waking me and also my aunt. I had forgotten my prank on my aunt as I raced to see if she was okay as she had screamed. I enter her room she was sitting up breast showing, and the baby reflecting the light from the light bulb. Her pubic hair still visible as well, I suddenly remembered my prank. She finally realized she was showing her assets, believing she had been masturbating her before falling asleep. Regaining her senses and said yes, I masturbate like everyone else. But my eyes were fixed on her breasts, she of course noticed and asked me to show my cock which grown inside boxer shorts making a bulge. Not thinking clearly, myself I showed it to her. She played with it and then asked me to fuck her and so I did twice. Again, in the morning before we had breakfast and a couple of times after breakfast and again after lunch before showering together and were sitting watching TV when others arrived back. The only thing different was my aunt was smiling, but my mother and the others saw the empty sherry bottle and put it down to that. Whether you can call the prank a success I don't know. But it improved life quite a bit, on our returning my aunt wanted my services regularly. She was a lot happier now and I'm getting my balls drained by her and my girlfriend doesn't fuck as much as my aunt, I'm lucky to one a week with my girlfriend, twice with my aunt sometimes more.
