Suzie was enjoying her mutual masturbation sessions with her son. The panty and Speedo stuffing turned her on to no end. Masturbation was great but what Suzie really wanted was a stiff cock shoved up her cunt. It was time to change the play.
Tom was sitting by the pool in his Speedo studying. After all that had happened over the last several weeks he always wore his Speedo now.
Suzie put on her red one-piece suit and went out to sit by the pool next to Tom.
There were no pretenses left between them. Suzie made sure Tom was watching when she casually put her hand down between her legs and started rubbing the red nylon fabric over her clit. The friction of the material made it feel so much better.
Tom's Speedo came to life. Watching his mother rubbing her clit right in front of him he moved his hand to his Speedo and began rubbing his boner as it got larger. The timing couldn't have been better. Just as Tom's cum started oozing through the material of his Speedo his mother started bucking her hips and shaking in the throes of a great orgasm.
Her bucking was involuntary. Suzie always started bucking when she came. She couldn't help it. For as long as she could remember this is how her orgasms affected her. She remembered the first time her sister had eaten her and had to use all her strength to hold Suzie's hips down so she could finish.
Tom scooped up the cum on his Speedo with his fingers and let his mother lick them before jumping in the pool.
Swimming around in the pool Suzie kept grabbing at her son's cock until it was again good and hard. She went up to the pool steps and leaned over. Pulling the tight red nylon to the side she told Tom she wanted him to fuck her then and there. And hurry up about it.
