When they were younger Nina and Nathan used to play together for hours. They were twins and discovered their bodies around the same age. When they were going through puberty they realized it felt great to play with themselves. They didn't know this was supposed to be a private thing. They would set in their room and watch the other. It was all innocent in their eyes. Once they got a little older they realized that what they were doing was wrong and they never spoke of it again. Until about 10 years later when they both returned home for a family function. They were left alone in the house for the afternoon and they got to talking about their relationships. Both of them were struggling and came to the conclusion that they should let off some steam. That's when the conversation took a turn. Nathan reminded his sister of the old days when they would jerk off together. Nina remembered vividly but she laughed nervously. All it took was a slight look from her brother to convince her to try it again. "No touching" she said to him with a grin. "We never did" He replied, "There was nothing wrong with it before" he added. They both took their clothes off slowly, waiting out the other to see who would reveal what next. Once they were both naked they admired the other and both commently on how well they've grown. Nathan was nearly hard already and Nina was shaking in anticipation. He started stroking himself slowly and she let out a soft moan as her fingers touched her wet pussy. They caught each other's eyes as they matched their pace. Every nervous feeling vanished when they looked at each other. Their hearts raced together, their hands worked together until they both reached their climax together. Nathan spewed cum up his belly as Nina convulsed on the couch.

 

When they came back down from their high Nathan looked around for a towel or some tissue to clean himself up. Nina ran to the bathroom to wash up and grabbed him some paper. He wiped up what he could but Nina noticed a few drops that he missed. She leaned in and wiped them up with her finger. He thanked her as she brought her hand to her mouth. She tasted his cum and her eyes lit up! She didn't know what came over her, she just knew she needed more! She dropped to her knees and without thinking, took her brother's cock into her mouth. Nathan struggled to stay still. He couldn't believe this sudden turn of events! She kept her head down as she sucked him off. He bit his lip trying not to scream in pleasure until he couldn't hold it anymore and 5 minutes after cumming, he blew a second load deep in his sister's mouth. Nina came up with a cum covered smile and said "We're doing this again".
