The weather has been beautiful lately and my stepaunt Crystal was spending a lot of time at the pool. She invi me over while my uncle Joe was away on business, to use their complexes pool. Crystals always raving about how amazing the pool is so I figure why not! I showed up my stepaunts and uncles place and Crystal was so ready for the pool. She already had her bikini on and that's when it hit me..I realized I forgot my swim trunks! I didn't have a bathing suit. I was so embarrassed, my stepaunt was ready to go and I was trying to find the words to admit the stupid mistake I made. I star explaining I forgot my swimsuit and sugges going home to get one but Crystal shrugged it off and said I could borrow one of my uncles. I assume we are about the same size now because I've been working out all semester long at college. Crystal came back out from their bedroom with a tiny pair of speedos! I laughed because I genuinely thought she was pulling a prank on me, my uncle can't possibly wear those?! But she said he can and he does! I was worried they'd be too smart, but Crystal said I should try them on first before complaining. So I agreed and tried them on, aaaaand I was right! They were way to small! I walked out of the room to show crystal and she star laughing at me! That didn't make me feel confident at all. She even poked more fun by wrapping her cover up skirt over me. I was so embarrassed, there's no way I can go down to the pool like this I thought. But something about the tightness of the speedo, my hot stepaunt poking fun at me was turning me on! I could feel the boner growing bigger and it star to actually hurt because the speedo was so tight. Crystal thought I was joking but then was shocked to realize I actually did have a huge boner! She told me to take care of it but I was so embarrassed I didn't want too, and it was really star to hurt! Crystal laughed again and then just said she'd help me if I stop complaining. Of course I agreed to it but I had no idea she meant by help me was to SUCK AND FUCK ME! How else would I get the boner down? She asked me when I stood their shocked. I was so turned on watching my stepaunt suck my dick I couldn't wait to fuck her too! Watching her deep throat, ride my cock, and bend over letting my stick in every inch. She even told me my dick was better than her husbands MY UNCLE! Which was an even bigger turn on I could feel my balls wanting to explode all over her. I wan to cover her pussy with my cum so I told her to lay on her back and let me fuck her hard. She loved it!!!! I couldn't hold it much longer and totally covered her pussy with my cum. It just didn't stop cumming!! She LOVED that even more!! I couldn't believe I just had sex with my stepaunt, and before I could bask in it she was putting back on her bikini! I was shocked to learn, my stepaunt and uncle live in a swingers complex and nudity is totally acceptable here so I didn't need the speedo anyway..but man, I'm glad I didn't know because wow I just fucked my stepaunt!! Now time to enjoy the summer pool weather!"
