Jason was smiling as he looked at his mom. "Wipe that smile off your face." Brenda yelled him in a whisper. "This better be over quick." She started b...uncing up and down on his cock relying on her feet for balance and support. Brenda positioned herself so the cock was rubbing her clit, and almost started a slow grind. "You guys ok in here" The voice of the sales lady came from the etrance end of the dressing room. Brenda stopped her motion and just sat there on her son's cock. "We're just. Quite nice and rather naughty." "I have the same thought. I've seen naked women on naturist beaches but I've never lain close to one. I like us being naked and close to each other. I find it rather exciting". "Is that why your cock has grown a little?" "So you've noticed? I hope you don't mind." "Not at all. I find it interesting. I know, from reading some naughty novels that a man can have a big erection when excited. I'd love to see yours fully up." "Happy to oblige, Sue. Here goes" I said. I. I lay very still, trying not to breathe, as he pulled out then slid it back into my anal depths – it did hurt like hell. Then I remembered Lizzie telling me how she faked her first few orgasms for him to ease the pain – perhaps I could. She came over, sliding her hands under my tits to squeeze and massage the nipples, then kissing me through that first fake climax.He did stop, pulling out with a quizzical look – had I really cum for him? No matter, Lizzie took his slippery member to the back of. Gave my tits a good workout, and then my nipples, teased them with the tips of her fingers. Very nice, and rock hard for her.Then slowly down to between my legs. She asked if I would shave her like you do me. When she smeared oil over my cunt lips then teased them with the tip of one finger it was very exciting.When she was laying on her stomach with her legs apart and the sun on her arse, she told me she loved a well hung man fucking her in that position. She asked if I would like to watch.
