Brad and Mark Walker, twin twenty-year-old brothers, sat in the family room of the home they shared with their parents and sister Gwen. They’d finished their second year of college and looked forward to the summer. Gwen had graduated from high school and planned to attend the same school like her brothers.

“You’ve got to check out the website I found,” Brad said.

Mark watched his brother enter the site and saw it was webcams. On the computer screen, a couple was engaged in oral sex.

“That’s cool, Brad. Better than the porn we usually watch,” Mark said.

“Right? Amateurs are hotter than actors.”

It didn’t take long for the two boys to become excited as they rubbed their cocks through their shorts. Brad and Mark had jacked off together before watching porn, so neither felt embarrassed because they concealed their activity, rubbing themselves through their clothes.

“Let’s take a break, get a beer, and go for a swim,” Brad said.

Mark and Brad changed into the suits. As they tucked their semi-hard cocks into their Speedos, they glanced at each other.

On their way to the pool, they grabbed beers from the refrigerator. Walking to the pool, the brothers dived in and milled around in the water. After spending fifteen minutes swimming, they got out.

Brad and Mark opened their beers, drinking from the cans. They stretched out on lounges, enjoying the summer heat.

“How did you find out about the cam site, Brad?”

“I discovered it while searching the web for porn. It’s cool, isn’t it?”

“Yeah, very cool. Did you notice the viewers give the people tokens?” Brad said.

Mark nodded.

“I read the broadcasters exchange the tokens for money. I think each token is worth ten cents. I wonder how much money they make.”

“One couple had a thousand tokens. That’s a hundred dollars,” Mark said.

Once their suits dried, Mark and Brad decided to watch the broadcasters again. They grabbed fresh beers, went to the family room, sat next to each other on the couch, and Brad selected a broadcast. The couple asked for tokens, removing an article of clothing each time someone tipped the requested amount.

“Damn, she has nice tits, doesn’t she?” Brad said.

“No shit.”

“Have you ever gotten one of your dates to show her tits?”

Mark shook his head.

“I haven’t either. The closest I’ve gotten was feeling up Sue on prom night.” Brad laughed. “She wasn’t impressed. Sue let me touch her through her dress but wouldn’t let me get to bare skin.”

“You did better than me. Jill wouldn’t let me touch her at all,” Mark said.

As the brothers watched, the couple stripped naked. Mark and Brad rubbed themselves when the girl began playing with the guy’s cock.

Mark groaned when the girl knelt and took his cock into her mouth. He rubbed his genitals, watching the woman blow her friend. Glancing at his brother, Mark saw Brad rubbing his cock too.

“Fuck it!” Brad said as he worked his cock out of the Speedo, stroking it while staring at the screen.

“What the hell are you doing?” Mark said.

“Sorry, but I can’t help it,” Brad said.

Mark watched Brad’s hand stroke his shaft, laughed, and said, “When in Rome.” He tugged his suit down, releasing his cock and balls. When Brad saw what his brother had done, he pushed his suit down to his knees.

The brothers watched the action on the screen and stole glances at each other. While it wasn’t the first time they jacked off in the same room, it was the first time they took their cocks out.

“This is so hot,” Brad said.

“What? Watching her suck his cock, or seeing me jack off?”

“Both.”

“Yeah, watching you is hot, Brad. I would love to get a blow job.”

“No shit! It would be amazing.”

Brad and Mark divided their time, watching the broadcast and each other. As if the twins could read each other’s minds, they stopped and drank from their cans.

“Do you want another beer?” Brad said.

“Sure.”

Brad stood, removed his suit, and headed for the kitchen. When he returned with the beers, he noticed his brother was naked. Laughing, Brad gave Mark a can, sat down, and watched the screen.

A few minutes later, the man pulled his cock out of the girl’s mouth, stroked it, then shot semen on her face. The girl extended her tongue, catching the thick fluid, then she waved, and the screen went blank, and Brad switched to another broadcaster.

They watched a girl on her hands and knees with a guy fucking her from behind while she sucked another man’s cock. Her breasts swayed as the men shoved their cocks in her mouth and pussy.

Mark stroked his cock and rubbed his balls while Brad pumped his hand on his dick. Neither brother felt any pain as the beers took hold.

“Fuck, I’d give anything to get a blow job,” Brad said.

“No shit. We need to find a couple of girls to suck our cocks.”

Brad watched his brother jacking off, feeling buzzed.

“Would you give one to get one?” Brad said.

Mark looked at his brother. “What?”

“I asked if you’d give a blow job to get one.”

“Are you suggesting what I think you are?”

Brad put his hand on his brother’s cock. “If you suck my cock, I’ll suck yours.”

“Are you fucking nuts? I’m not gay,” Mark said.

“I’m not gay either. I’m getting drunk and horny, but I’m not gay. I don’t want to kiss or fuck you. I just want a blow job.” Brad stroked his brother’s cock.

The idea of giving his brother a blow job unsettled Mark, but the feeling of Brad’s hand stroking his cock turned him on. Throwing caution to the wind, he gripped Brad’s cock. The two brothers didn’t say anything while caressing each other.

Taking the lead, Brad leaned closer, covered his brother’s cock with his mouth, and bobbed his head. Mark watched as his cock went in and out of his brother’s mouth.

“Oh fuck, that’s amazing,” Mark said.

Brad removed his mouth. “It’s your turn, Mark.”

“Aren’t you going to finish?”

“Sure, as soon as you suck my cock. I want to make sure you’ll do it,” Brad said.

Mark nodded, slipped off the couch, knelt between his brother’s legs, and stroked his cock. He lowered his head and let Brad’s hard cock glide over his lips. It took a moment to accept what he was doing before he bobbed his head, feeling his brother’s cock sliding over his tongue. Mark began enjoying the strange feeling as he got into it. He put his hand between Brad’s legs, caressing his balls as he took as much of his brother’s seven-inch cock as possible.

Brad groaned, put his hands on Mark’s head, and guided him up and down. Mark applied suction, feeling his brother’s cock swell in his mouth. Brad threw his head back as his cock shot semen into Mark’s mouth.

Mark gagged when his brother’s cum went into his throat, then he felt the semen run down his throat. Mark ran his tongue around his brother’s dick when the surges stopped, sat back, and swallowed.

“What the fuck! You could have warned me,” Mark said.

“Sorry, Mark. I couldn’t help it.”

Mark stood up, knelt on the couch, and waggled his semi-erect cock in front of Brad’s mouth. Brad put his hands on his brother’s thighs, pulled him close, and took his cock into his mouth. Mark held Brad’s head, rocking his hips while his brother blew him.

Unlike his brother, Mark warned him when he felt his climax build. Brad nodded and continued sucking his cock. When Mark came, Brad ingested his cum without coughing. He felt the surges diminish, keeping Mark’s cock in his mouth until it softened.

“Wow, that was great,” Mark said.

“It wasn’t what I expected, but I liked blowing you. Would you do it again?”

“Yeah, I’ll do it again.”

Brad and Mark went to their room to dress, then to the family room to watch television while waiting for their parents and sister to get home.

“What did you guys do today?” their mother asked as she put dinner on the table.

“Brad and I hung around, watched television, and went swimming,” Mark said.

“Sarah and I went to the mall and a movie,” Gwen said.

The family chatted while eating their meal. Mark, Brad, and Gwen cleaned up and washed the dishes when they finished.

While the family ate breakfast the following morning, their mother asked about her kids’ plans for the day. Mark and Brad said they would play video games and hang around the house. Gwen said she was going to Sarah’s house.

After their parents left for work, the siblings prepared for their day. Brad and Mark set up their game console in the family room, and Gwen went to her room to dress.

Gwen took a shower, shaved her legs and crotch, dried, then fixed her hair. She went to her bedroom and selected her outfit. Taking a white lacy bralette from her drawer, she put it on, then adjusted her full round breasts in the garment. After putting on a matching thong, she went to her closet for a short sundress, put on her sandals, and looked at herself in the mirror. She ran her fingers through her shoulder-length blonde hair, smiling as she thought about her cousin Sarah. Since her cousin introduced Gwen to sex with a girl, she couldn’t get enough.

After their sister left, Mark and Brad went to the family room and started playing a video game. After two hours, Mark said, “Are you okay with what we did yesterday?” Brad nodded. “Want to do it again?”

“Hell yeah.” Brad stood and removed his shorts.

Mark undressed, knelt on the floor, grabbed his brother’s cock, and pulled it into his mouth. As Mark bobbed his head on his brother’s hard cock, Brad rocked his hips. Unlike yesterday, the twins hadn’t been drinking, and it wasn’t long before Brad announced his climax. Mark continued sucking as his brother’s cock shot cum into his mouth, then swallowed.

Brad knelt on the floor, blew his brother, and rubbed Mark’s balls. Mark held off his orgasm, enjoying the feeling of having his cock sucked provided.

Gwen spent a couple of hours at Sarah’s house but left when her cousin said she wasn’t feeling well. She went home and walked to the family room, gasping when she saw Brad with Mark’s cock in his mouth. Before her brothers noticed she was there, Gwen stepped into the room. She felt her pussy tingling as she watched.

When Gwen said, “Hi. Can I try that?” the twins gasped.

Mark pulled his cock away from Brad and looked at his sister. Gwen giggled, moved into the room, knelt next to Brad, and wrapped her hand around Mark’s cock.

“I’ve never sucked a cock, but I want to try.”

Knowing they’d been caught, the brothers shrugged their shoulders. When their sister put her mouth on Mark’s cock, Brad watched. “If you want to suck our cocks you have to strip.”

Gwen removed her mouth, stood up, and removed her clothes. Brad played with her full breasts when she knelt again, moaning around Mark’s cock as her brother massaged her tits. Mark came, sending cum into his sister’s mouth. Gwen pulled her head back, causing the following spurts to hit her face before taking him back into her mouth.

Giggling, Gwen sat back on her heels and used a finger to scrape her brother’s cum into her mouth.

“Are you two gay?” Gwen said.

“No, we wanted to know what it felt like to get a blowjob,” Brad said.

Gwen chuckled. “Yeah, I did too. I know what pussy tastes like but never had a cock.”

“You fool around with girls?” Mark said.

“Just Sarah. We eat each other and stuff. Both of us are virgins.”

Brad grinned. “Are you lesbians?”

“I don’t know. Sarah and I have never been with a boy to find out. Sucking cock is cool, and I like it.”

“We’ve never seen a real pussy. Can we see yours?” Mark said.

Gwen sat on the couch, grabbed her legs, and pulled them open as her brothers stared for a moment, then touched her crotch. She wiggled as they rubbed and probed her. When Mark licked her pussy, Brad turned his attention to her breasts, massaging and sucking them.

Mark slipped a finger into his sister’s pussy, looked at her, and said, “Can we fuck you?”

Smiling, Gwen nodded. Mark knelt between her legs, gripped his cock, and pushed it into her. She moaned as he fucked his sister and pulled Brad’s head to her chest.

“Wow! A real cock is better than the dildo Sarah fucks me with.”

Mark’s orgasm built, then he came. When Mark sat back, Brad replaced him and fucked Gwen. She wiggled and rubbed her clit, relishing the feeling of a cock stuffing her pussy. Brad came, shooting his cum into his sister’s pussy. When the brothers realized Gwen hadn’t come, they took turns licking her gooey pussy until she did.

The siblings went skinny-dipping, returned to the house, and continued sucking and fucking until it was time for their parents to get home. They dressed and sat in the family room, discussing the sexual fun and agreeing they wanted to continue exploring.

“I’m going to invite Sarah to swim tomorrow,” Gwen said.

“Do you think she’ll come?” Brad said.

“More than once if we’re lucky. I know Sarah wants to fuck. I have a plan.”

Gwen told her brothers about her plan to include their cousin, and they agreed.

After the parents left for work, Gwen called Sarah, inviting her to the house, saying her brothers were out. When Sarah arrived, she and Gwen went to the family room, kissed, removed their clothes, and started eating each other.

Per the plan, Mark and Brad walked into the room, watching their sister and cousin engaged in a sixty-nine. Gwen was on top, blocking Sarah’s view as the brothers came closer, removed their shorts, and knelt next to the girls.

Gwen lifted her head and said, “We need real cocks, Sarah.”

When Sarah moaned and nodded, Gwen moved so her cousin could see her naked brothers. Sarah screeched, sat up, and covered her breasts with her hands. Gwen chuckled, grabbed Brad’s cock, and put it into her mouth.

“What the fuck is going on?” Sarah said.

Gwen released Brad’s cock, smiled, and told Sarah about catching and joining the boys.

Sarah gasped. “You saw Brad suck Mark’s cock?” Gwen nodded. “Bullshit!”

Mark leaned over, took Brad’s cock into his mouth, bobbed his head, and stood up. “We suck each other, Sarah.” He stood before his cousin. “Do you want to try it?”

Sarah looked at Mark’s cock, shrugged her shoulders, and wrapped her hand around his shaft. She stroked him, then took his dick into her mouth. It took a moment for Sarah to feel comfortable before she bobbed her head, taking as much of his dick as possible.

“Isn’t a real cock better than the dildo?” Gwen said. Sarah nodded and moaned around Mark’s cock. “If you think sucking cock is good, wait until you feel it in your pussy.”

Sarah removed her mouth, stretched out on her back, and spread her legs. “Why wait?”

Mark knelt between Sarah’s legs, gripped his cock, and pushed it into her pussy. She groaned and flailed her legs as she lost her virginity to her cousin while Brad and Gwen watched. Mark fucked her for ten minutes, came, and sat back. Brad got between Sarah’s legs, licking and sucking her pussy until she had an orgasm.

“Damn, fucking is better than I thought it would be,” Sarah said.

Gwen nodded. “Right?”

They took turns sucking and fucking each other for the rest of the morning. Sarah and Gwen experienced their first spit-roast when they took a cock in their pussy and mouth. While the brothers recovered, the girls ate each other’s pussies.

After taking a break for lunch, they swam to rinse the sweat from their bodies. They got out, dried, and went into the house to continue their sexual discovery.

Exausted and sated, they relaxed in the family room. They shared smiles and touches while revisiting the day’s events.

“I think this will be an interesting summer,” Sarah said as she rubbed Gwen’s pussy.

Chuckling, Brad caressed Mark’s cock and balls. “I think it will be a blast.”

Before dressing, they shared a group hug, each caressing the other. While putting on their clothing, they agreed the four were willing to explore their bisexuality and see where it led them.

Gwen invited Sarah to dinner and to spend the night. After the parents went to bed, the girls went to Brad and Mark’s bedroom, watching the brothers sucking each other’s cocks. They got onto the bed and ate one another’s pussies for a few minutes, then switched. Mark and Sarah came together head to crotch while Brad fucked his sister.

Sarah and Gwen knelt on the bed while the brothers took turns fucking them. After the boys came, the girls ate each other, cleaning the other’s pussies.

“We need to get to sleep. I want to go at it again tomorrow,” Gwen said.

“Yeah, so do I. This has been a great day, but I think things are going to get better,” Sarah said.

When they left the boy’s room, Sarah and Gwen climbed into Gwen’s bed. They hugged their naked bodies together, rubbed each other’s breasts, then fell asleep. Brad and Mark got into their beds, then Brad got up and joined his brother in his bed. They hugged and stroked one another.
