Bobby was looking out the window of his room. It was the window same one that faced Bonnie's back yard. It was the same window where he first saw her sunbathing and masturbating while he watched her. It was where he first got a look at her large breasts for the first time.
He remembered that it was such a small bikini she wore each day and from where he was standing above her he could look straight down between her cleavage and imaging how it would look if she didn't have that top on. He could also see her adjusting her bottom and sometimes she would lift the top and he could see down to her pussy hair. It stimulated him like no other female had ever done. This one was real not in a magazine. This one was older and more mature and was built like a dream to this young teenager.
Then one day when she saw him looking at her she smiled up at him and slowly removed the top of her bikini showing him all of her tits. She lifted them and examined them feeling them up and making her nipples hard and long. Bobby jerked off day after day looking those bit tits and red nipples and watching Bonnie tease him and drive him wild with lust. I mean can you imagine how a teen boy would react to seeing the most beautiful woman he had ever seen in real life showing him her body and touching herself? He exploded every day after school cumming all over his hands and the window and wall.
"This is where it all started", he said to himself.
Bobby stood there for a while and grabbed his crotch thinking of how Bonnie looked that day. He was waiting for his mother to call him into the shower so they could wash each other and continue the day of sex they were having. But as his brain drifted back to that day with Bonnie he sort of forgot about his mom.
Then he heard her call him but just as he was going to turn around and head to the shower with him mom he saw movement out of the corner of his eye. Bonnie was walking out to the lounge chair in her small bikini with a guy, a huge guy. He must have been every bit of 6'4" and looked like a weight lifter, huge shoulders, arms and thighs and he was dressed in a bathing suit that was pushed way out in front of him. Bobby was thinking Bonnie has company alright and the guy looks like he had a huge cock.
So Bobby smiled and said to himself: "What the hell? I think I'll stay here and watch for a bit."
As he watched Bonnie sat in the chair and then lay back putting her legs up so she was stretched out. The guy sat next to her and ran his hands up her arms and over her shoulders as he bent down to kiss her. She stroked his thigh as he did it. Bobby could see his big cock jump moving the suit. Then the guy smiled at her and cupped both of her big breasts in his hands. He had huge hands too. Bobby was amazed at the size of this guy. "He must play football or something he is a giant" he mumbled.
He watched as the man played with Bennie's tits and then lifted the top up over them and over her head. Completely nude down to her flat belly now the guy smiled at her and bent his head down and sucked on the nipples. Bobby remembered how it felt to do the same thing. Bobby's cock grew as he watched the guy mall her big tits and stimulated her nipples with his mouth and tongue. God she had nice breasts.
Finally Bobby began to rub his cock on the outside of his shorts. That's all he had on since he had been fucking his mother all morning! He watched as the guy hooked his fingers in the sides of Bonnie's bottoms and she lifted up as he pulled them down her thighs and off her feet. Bobby stroked his cock harder squeezing it and pulling on it while it was still under his shorts.
Now completely nude she opened her legs and the guy ran his hand up and down her inner thighs cupping her pussy like Bobby had done o hr in that very chair. Bobby knew Bonnie would be wet and he grabbed his cock as he watched this new man masturbate Bonnie with his big fingers and hands. Bobby could see Bonnie was growing more and hotter with the minutes that passed. The guy's fingers and hand were wet from her juices. Bobby knew that Bonnie had some juice. He could see her rubbing his large lump in his bathing suit. "God he looks huge", Bobby was thinking.
Finally the guy stood up and Bonnie pulled his suit down slowly releasing his big dick. Bobby sucked in a breath when he saw the large thick cock come popping out over the top. The guy was a giant everywhere including between his legs too!
She took his cock in her two hands and had still a few inches that stuck out over them. She pulled him towards her as she opened her mouth and took his cock head and licked it a few times with her tongue. Then she sucked this guy just like she had sucked Bobby! The guy held her head and faced fucked her as he stood there watching her suck him. Bobby had his cock out and in his hand now as he slowly jerking off and watched the two lovers.
Bobby watched as the guy's cock grew even larger and thicker as Bonnie used her sucking powers on it. Finally he pulled his dick out of her mouth and moved down to release the top of the chair so Bonnie was completely laying back. Bobby watched as that big dick swayed and jumped and moved with the man. It was almost pointing up towards his window.
Then the guy opened Bonnie's thighs and moved between them. He lifted her ass up off the lounge chair like she only weight 20 pounds and positioned his cock at her pussy opening. Bobby jerked off faster and harder now. He knew Bonnie was going to be fucked hard and he loved watching it.
As bobby watched his mother came out of the bathroom and into the bedroom. She saw Bobby watching out the window and saw him holding his cock and jerking off. She moved to him. She looked down and saw what Bobby was looking at and the smell of her body wash made Bobby turn around. She put her arm around her son and whispered: "So this is why you don't come into the bathroom and let me wash you. YOU want to see bonnie with her new man get the fucking of her life. Well I want to watch it too,"
She moved next to her son and removed his hand from his cock. Then she took it and slowly jerked him off as they watched Bonnie spread her legs wide to accommodate this huge man moving between them.
The guy wet his cock with spit and pushed. Bobby and his mom could both hear Bonnie moan as the big dick went into her hole. With the widow open they could hear the fucking and the moans and sighs and grunts from both lovers. Soon his cock was wet and shinning in the summer sun. It was glided in and out of Bonnie's hole easier and smoother now. His thickness was now being taken by her pussy and she had adjusted and was now really enjoying the fucking she was getting.
Bobby and his mom both watched as the guy held Bonnie's ass up off the chase lounge and began to fuck her harder and super fast. Bonnie opened her thighs wider and threw her head back. She had her eyes close and they could see her face. She was in a state of total bliss and the guy was ramming his big dick in and out of her fast and hard.
His big hands were covering Bonnie's tits and squeezing them hard. He was leaving marks on them. When the guy was about to cum he yelled out and as they watched they could see him shoving hard with each shot of cum he pumped into Bonnie cunt. Bonnie heard him cry out with his lust and felt him cumming in her cunt and when Bonnie opened her eyes she was looked right into Bobby and his mother's eyes.
