There laying in the matted down grass was a couple half undressed doing some heavy groping. The female had her blouse unbuttoned, bra unhooked and ...down around her waist and the guy was cupping her tits and sucking on her very erect nipples. After a few minutes, she pushed up and told him to lay down and she then unsnapped and unzipped his jeans and reached down his underpants and pulled his erect cock out. She then pulled his pants and shorts down to his knees and began to give his. She spent some time stroking me from my chest to about my knees with her hands then coming back up my inner thighs to cup my genitals gently in her hands. Then she gave me a breast massage bringing her breasts up to the top of my chest then sliding down to envelope my penis between her breasts. Wow, was she good! Meanwhile, I was pressing my penis into her hands, then into her belly and her breasts. And all the time, she was looking straight into my eyes and smiling. I asked her if she gave. During the weekdays they had a normal mother-son relationship, maybe one that was better then most, but on Saturdays, Carol accepted, she was nothing more the her son live sex toy and there weeks She wished every day was Saturday.While remembering it all, Carol's fingers slip into her wet twat. After a few moment of touching herself Carol called out, "Mind if I join you, Son?" Grinning, Johnny opened the door for her. Johnny started to say something but Carol kissing him immediately shut him. Walter too had his turn, cherishing every spank and like Matt, choosing to affirm his love for her by stroking her face and her hair and kissing her gently on her cheek between spanks. ‘Wonder how far they will go. Surely they will not strip me naked,’ she wondered. Matt smiled when he noticed the chair and the mirror because it told him that Don and Suzy had now made it a regular practice. He led Sherry to it and she assumed the position. Suzy happened to come down to check on the refreshments.
