As I began to wake up from my nap, I noticed the room was a lot darker than when I fell asleep. I didn't plan on taking a long nap but with all that happened earlier, I think I was a lot more exhausted than I thought. I couldn't feel Aunt Brooke's naked body close to mine anymore, and when I rolled over, she was nowhere to be seen. She must've gotten up to go get dinner at some point. I thought to myself as I checked the time on my phone. It was well past dinner time but still relatively early in the evening.
My mind was replaying the events from the afternoon, and I definitely didn't mind. I then remembered what Brooke had said to me before I fell asleep, and I started wondering what she could've had planned for tonight. The excitement of those thoughts sprang me out of bed so I could get dressed and join the rest of the family. I threw on some shorts and a t-shirt and opened the door. When I walked into the kitchen, grandma and Aunt Mindy were cleaning up from dinner; everyone else was in the living room. Aunt Mindy told me to take a seat at the bar while she fixed me a plate. I was starving from all that fun earlier!
I sat there eating a delicious home cooked meal while getting to catch up more with grandma and Aunt Mindy. Occasionally, my thoughts would go back to being in the shower with Donny and it made it a little difficult to focus. I also thought about what Aunt Brooke had said earlier about her and Donny. That made me wonder if Aunt Mindy was involved in any way. I think my subconscious was too focused on other thoughts though because I didn't dwell on those thoughts too long.
My grandma told me that once the kitchen is cleaned up, we're all going to head down to the dock to hang out while there's still some daylight out. I was looking forward to relaxing by the water again and said I'd join once I finished eating. The rest of the family came in from the living room and when I saw Donny wearing just a pair of swim trunks, all I could think of was sliding them down and being in front of him on my knees again. Everyone gathered their stuff to head down to the dock and I was soon going to follow. Before they started making their way out the back door, Aunt Brook said she was going to grab some waters for everyone and that her and I would be down in a little bit.
I finished eating once everyone was out the door and Aunt Brooke was kind enough to take my plate so I could go change into my bikini and swim dress. Once changed, I walked back into the kitchen and told Brooke I was ready to go. She had already changed into another bikini top but just had some cute shorts on instead of bikini bottoms. As I met her at the back door, she gave me a big hug, pulled back, and then gave me a soft kiss on the lips. She picked up the cooler off the ground, threw it over her shoulder and said, "I really enjoyed our time earlier! Now let me fill you in a bit on what I have in store for us tonight."
As we made the long walk down to the dock, she filled me in on her evening plans and I had to admit, I liked them. Aunt Brooke told me that she was only going to hang out with everyone for a little bit and then she'd let everyone know she was tired and would be going back to the house to shower and relax. She said that Donny knew about her plan but nothing more than that. I started getting more curious as to where I'd fit in but she stated that he was going to wait about ten minutes before making some excuse to go back to the house. My mind was beginning to race with thoughts about the both of them together and just before we reached the top of the dock stairs, she said, "He's going to come join me in the shower and I'm going to make sure to put on a special little show for you. Like I said earlier though, you'll need to be sneaky when you peak in because Donny doesn't know you'll be watching."
I could feel my bikini bottoms getting a little wet as I started to get really excited now. When we were finally on the dock, we sat down on some lounge chairs to enjoy the cool evening. After about an hour of talking and watching the cousins start to fish, Aunt Brooke announced that she was going to head back to shower and relax. My heart started racing a little faster and not long after she was out of sight, Donny said he was going to go up and check on the homemade ice cream. I watched him walk away and I'm not going to lie, the whole time I pictured him naked.
As I laid there trying to think of an excuse to go the house too, I decided to act a little sleepy and rested my eyes. My grandma noticed and suggested I'm more than welcome to head back and lie down for a bit. I slowly got up and told her I'm not missing dessert so I'll still be joining everyone on the deck later! Grandma said they'd be ready for ice cream in another hour or so and she'd wake me when they got back to the house. I made my way up the stairs and once I knew I couldn't be seen from the dock, I started walking a little faster.
When I reached the back door to the house, I opened it very quietly and tip toed in. After I shut the door behind me, I started making my way down the long hall to my grandparent's room. As I was getting closer to the room I was staying in, I decided to slip off my swim dress and throw it on the bed. I still had my bikini on but I was secretly hoping it wouldn't stay on for much longer. Before getting to the doorway of the master bedroom, I did as Aunt Brooke did and got down on my hands and knees.
The only sound I could hear was the running water of the shower and I was getting more and more excited the closer I got. I had some ideas on what I might be getting ready to see but I don't think I was fully prepared for it. All I knew for sure is that they'd both be in the shower, hopefully not in their bathing suits either. Slowly, I poked my head through the doorway and looked left. What I saw practically took my breath away!
Donny was standing and facing away from the shower head with his arms behind his back. The water was hitting the top of his back and as my eyes started drifting down, that's when I saw Aunt Brooke squatting down! They were both naked and Brooke had Donny's hard cock in her mouth! I could feel myself getting hot and the tingling sensation was getting more intense. I watched Aunt Brooke slowly tease Donny's big cock with her tongue. I've fantasized about watching her suck a guy's dick before, but I had no idea just how hot it'd be to witness!
Brooke had told me before that she's a sucker for a guy with a big dick and it was very evident from watching her. She had one hand wrapped around the base of his cock while she was holding it upwards. Her other hand was down below her waist, and she was lightly rubbing her clit while licking his cock from the base to the head. When her tongue reached the tip, she opened her mouth and slowly took all 9" in. She held her head there and I heard a sexy moan escape Donny's mouth. Watching Brooke engulf her brother's massive cock had me leaking through my bottoms now.
She began to slide her mouth back off his cock. Once she reached Donny's head, she took it all right back in her mouth. Her pace began to pick up while she started stroking his cock. Donny moved his hands by his side except only one ended up staying there. The other one was gently placed behind her head. She slid her mouth to the tip of his dick again and looked up at him. Donny looked down and smiled at her, then he ever so softly grabbed her hair. She then went to her knees and that's when he started thrusting his hips back and forth. He started off slow so she could get used to his cock sliding in and out of her mouth. As soon as she took her hand off his cock and placed it on her breast, the pace quickened.
Aunt Brooke was now gagging on Donny's cock, and you could tell they both enjoyed it. Brooke was solely focused on pleasing her brother and I was in amazement at how well she took his cock. I've always been jealous of her, but this was unlike anything else. I've never wanted to be her so badly in my life. Having such a gorgeous body like hers and being in the shower with Donny while I'm on my knees as he fucks my mouth with that cock... I was getting beyond worked up at this point! I started to rub my clit over my bottoms and as I did, Donny looked down at Brooke and said, "I've so missed your mouth, sis!"
