Carlo was playing video games in the living room. Aunt Jackie was shopping with Kelly, and Martin was reading a book. Carlo wanted to share his good news with his brother.
"Martin, I became a man the other day."
"Yea, sure. With who? You never leave the house."
"If I tell you, you have to promise not to tell."
"Okay, I promise. Who did you have sex with?"
"Aunt Jackie and I had sex together."
"Why would Aunt Jackie have sex with a dork like you?"
"I guess she wanted to have sex. Man. You should see her tits and ass. She has a gorgeous body. She sucked my cock for a long time too."
"Wow, Carlo. That's cool. I wonder why she never approached me?"
"She's horny and loves sex. I bet she would have sex with you too."
"Interesting. Maybe I will make a pass at our aunt and see if she bites. I think Aunt Jackie is hot. I could show her a thing or two."
"Maybe if you have sex with her, we could have a threesome with her. Maybe we could tell Kelly and see what she says."
"Dude, why would we tell Kelly. She is our sister."
"She may be our sister, but she is horny too. I saw her sticking her hairbrush into her pussy one night. I wonder if she has had sex yet."
"Gross. Why do you care about our sister? Now, that is incest, and you should stop thinking about her."
"Why is she sticking a hairbrush into her pussy? I have a nice cock that could slide right into her. We could both fuck her. Don't you think she is hot?"
"She's my twin, and no, I don't think our sister is hot. I think our aunt is, and I will see if she will have sex with me. I am kind of hurt that she approached you first. I'm eighteen and legal for sex. Why is she having sex with you? You are such a nerd!"
"I'm not nerdy anymore. I have had my dick sucked, and I have had sex with our gorgeous aunt. Aunt Jackie swallowed my cum and thinks I am hot. I was kind of surprised she didn't ask you first. You are quite popular and a football player. I guess she figured girls throw themselves at you."
Martin was getting hard while his brother spoke about their aunt. He always liked his aunt and was feeling hurt that she hadn't made a pass at him. He was going to say something and hope she would take the bait.
"You and Kelly need to leave for a few hours. Maybe go to the beach. I want to have some time with our aunt. Maybe she will have sex with me too. When they come back, tell Kelly you want to go. She will be glad to go. She loves the beach."
"Okay. I hope Aunt Jackie does the same stuff we did. Wait till you see her breasts; they are round and so firm. She has a shaved pussy, and she swallows cum. Aunt Jackie is very sexy."
"Will see if she takes the bait."
Martin hoped Aunt Jackie would have sex with him too. Lately, his girlfriend wasn't putting out like she was a few months ago. Martin was annoyed with her and was thinking about breaking up. He and his girlfriend were going to different colleges in the fall, so it didn't make sense to continue dating.

Kelly and Aunt Jackie came home from shopping. Carlo ran down the stairs to talk to his sister.
"Kelly, let's go to the beach. It's such a nice day."
"Sure. Let me get my suit. Does Martin want to come?"
"No. Martin said he would stay home."
"Okay. I'll be right down. I have to change."
"Hi, Aunt Jackie. How are you?"
"Great. How are you, Carlo? We have to visit again soon."
"Okay. Maybe later I could give you a massage. You seem to like those."
"Sure. I love massages."
Carlo smiled at his aunt. He was glad she wanted to see him again. He went upstairs to put his bathing suit on and packed a bag for the beach.
"Come on, Kelly!"
"I am ready. It will be nice spending time with you, little brother."
"Great, let's go."
Carlo and Kelly left for the beach. Aunt Jackie went out by the pool, where she sat on a chaise lounge looking at a magazine. Martin put his suit on and went out to where Aunt Jackie was.
"Hey, Aunt Jackie, you look amazing! Do you need help with some oil? You don't want to burn. The sun is so strong."
"That would be great. Here is the oil."
Martin took the oil and poured it on Aunt Jackie's back.
"Maybe you should take your top off. You wouldn't want any lines."
"Good idea."
Aunt Jackie pulled the string on her bikini top, and Martin started to rub the oil into her skin. He made sure to give her a massage while doing it.
"You have nice strong hands, Martin. It feels so good."
"Great. I will do your legs too. You wouldn't want them to get burned either."
Jackie let out small moans while her nephew massaged her skin with the tanning oil. Her pussy was wetting up in her bikini. She wondered if Martin would want to fool around too. Carlo was a good student.
"Why don't you turn around. Let me put the oil on your breasts."
"I know what you are doing. Carlo must have told you something."
"He did. He said you devirginized him. How come you didn't want to have sex with me? I would love to be with you."
"We can have sex if that's what you want. I figured you must get lots since you are popular."
"My girlfriend hasn't put out lately. Looking at your hot body makes me hard."
Martin took his aunt's hand and put it down his trunks. His cock was hard and hot.
"Wow. You are a big boy. I love big cocks. Take it out, and let me see it."
Martin took his trunks off and stood next to his aunt's chair. She grabbed his cock and stroked it up and down. She liked how big he was. His cock was much bigger than Carlo's, who also had a big cock.
