Part 1 happened on Saturday and Sunday.
Wednesday.
Dan was out mowing the lawn. It was getting hot out so he took his shirt off and threw it in the pool. Sweat was rolling down his body. He had no idea there were eyes on him. Charlotte was watching, his stepmom, Celeste was watching and Soledad, their neighbor was watching from her balcony. He looked up at the balcony and swore the neighbor lady was rubbing her pussy through her bikini. Dan has jacked off to thoughts of Soledad and her daughter Marisol, on numerous occasions and now, is she, he thought.
He had finished with the yard work and headed inside to shower. Celeste asked if he wanted some water and he nodded. "That feels great going down," Dan said.
"I bet it does," his stepmom mumbled into her mug as she took a sip of her coffee.
"I'm going to take a shower now Mom," Dan said and headed upstairs. He disrobed and admired himself in the mirror. He loved his body and especially his dick. He'd thought about trying to suck it even but he thought that might make him gay and never gave in to the urge. With that he headed into the bathroom not even caring about the others in the house.
The shower started out cold but her turned it warmer and thought about his neighbor. He stroked a couple of times but thought it would be better in his room. So he grabbed a towel and wrapped himself, not drying just wrapping and headed back to his room. Once inside he dropped the towel and looked at himself again. Running his hands over his body, stopping on his sex. Dan rubbed his dick with thoughts of Soledad playing with herself. As his cock grew harder, he sat on his bed and wondered about her pussy. He knew she had nice tits as he'd seen her at the pool before. He stroked himself hard. Pumping his meat, thinking of what her pussy looked like. He stood up and walked to the window still stroking. As he looked toward the balcony, Soledad had her bikini pulled aside and he saw her dark hair and she was fingering herself and looking straight into Dan's window. This made his balls tingle and he knew there was no turning back now. Just then, his door opened and his stepmom entered and gasped. The first rope of sperm hit the window. Dan turned to see his stepmom and the second rope of sperm flew over and landed on Celeste's blouse, the third hit her skirt. "Oh Fuck, MOM" is all he could say.
"Well sweetie!" Celeste said and then continued, "I was coming to check on your shower, I didn't think I was going to get one."
A snicker escaped Dan, "I'm sorry, Mom."
"It's ok hun, I completely understand. Boys your age are always masturbating," Celeste said. Then she left and closed the door. Outside his room she wiped up some of his cum and licked it off her fingers.
Dan thought, "What the fuck just happened." His stepmom and Soledad the neighbor, had just watched him blow his load. He was embarassed, excited and most of all worried about the house dynamic now that Charlotte and her mom had seen him naked and more.
Dan went for a run to clear his head. He thought of only good things that could be ahead. When he rounded the corner, he saw Soledad leaving his house. He wondered if this could stem from what happened earlier. He knew they got together now and then for coffee but this was too soon after, this morning.
As Dan entered the house, Celeste told him that Soledad came over to see if he was interested in mowing her lawn. He said he'd think about it.
"Hey Celeste, about earlier." Dan said.
"Everything is good." she replied and said she was headed out.

Friday.
Dan came in from a run and noticed John's car in the drive. Charlotte's boyfriend, John would come over now and then but Celeste was home each time. Dan didn't think much of it at the time and headed into the bathroom.
Meanwhile...Charlotte was sitting in a chair
sliding her favorite toy into her wetness. John was standing across the room watching and stroking himself to hard. Charlotte thought she heard Dan come in and her wheels started spinning. She told her boyfriend to lie on the bed. Char then hovered over John's cock and lowered herself. Feeling his warmth inside and knowing her brother was in the house, a shiver ran through her.
Dan was lathering himself and touching his dick and then his mind wandered to Char and John. That made for a quick shower as his curiousity was getting the better of him. He had a serious urge to get off.
He moved stealthily down the hall to find her door closed. As he got closer, he could hear the pleasurable sounds of sex. He was happy when he checked the door- it wasn't locked. As he opened it, he saw Charlotte riding John reverse cowgirl across the room. Her ass looked so good as she rode up and down on her boyfriend. Then everything changed when he thought he heard her say, bro.
"You like fucking me don't you, bro?" she asked.
"I love it so much, sis," John said and continued, "I like this roleplay, Char."
"You want to suck a dick don't you John?" was her next question.
Dan was confused. Charlotte is fantasy roleplaying bro/sis with her boyfriend who is, bi? WTF, he thought.
Charlotte then buried John's cock inside her and turned to see Dan in the crack of her door. She waived him in and told John to keep his eyes closed. As Dan moved in to her room, his hand brushed the towel and it fell, showing his sister his hardened state. She smiled and morioned for him to stay quiet.
Charlotte climbed off of John, and the bed and led Dan by his cock to the side of her bed. There she traced her fingers around John's lips and then slid her dildo into his mouth. Her other hand was stroking Dan.
"Are you thinking that cock feels good, John?" she asked. "Do you like the feel of a cock in your mouth?" she continued.
Dan looked at Charlotte with a questioning look. She then removed her toy from John's mouth and pulled Dan closer and pressed his head to John's lips. John licked at the new feeling, opening his eyes to see his girlfriend's brother's cock. Charlotte pushed Dan closer to John as his cock moved into John's mouth.
Charlotte kissed Dan while John sucked his manhood. She then whispered to her brother, "John has fantasized about sucking a dick for some time."
John was going to town on that cock. Dan thought it was feeling good too. So much so, he kissed Charlotte deep and lost track of what was happening and shoved his dick deep in John's mouth, which made him gag. Dan pulled out and apologized.
"It's ok, bro." John said.
