One fine working day I planned and the convo started like this between my darling and meMe: hey mom today I planned a surprise in the eveningMom: what...is it beta?Me:mummy it is a surprise!!Tell dad that you have a board meet in the evening and come to public park at 5:30Mom:public park!!!!!Me:yes mom in the park!!And no more questions mom .Come it a nice modern dress mom.Mom:ok son I am excited to know the surpriseWill meet in the park mom byeee!!!!Mom:bye beta!!!!I was waiting for the clock to. I growled lowly that the both of us were horny and two people having sex is always better than one.As Gramma sat next to me I continued to stroke my cock. Not wanting to scare away my prize, I placed my hand on her bare leg and softly asked her to remove her bra. I told her she had great looking breasts and I needed to see them one more time. Without any hesitation she reached around her back and the bra fell free. The first thing I noticed was her nipples. They were at least an inch long and. “The other would need a lot of attention and a lot more time”. She just smiled but made no attempt to close the gown that now showed almost her entire nudity and it was desirable.The snack was over now as she washed the dishes he came up behind her, gripped those hanging melons, squeezed and pulled the nipples that hardened with each touch and then moved to her groin, rubbing her up, pulling the hair and then working his fingers between the lips of her sex; while she began to pant and offer. For the next two months things were quiet between mom and me. Then dad went on a golfing trip fro the weekend. Suddenly there was mom at my bedroom door wearing nothing but black stockings, a garter belt and a black bra with holes cut in the material so her nipples poked out. She grabbed me, kissed me, and hugged me tightly against her body. Its time, son. I want you to fuck mommy! I want your cock in the hole you came from! I want to feel your cum inside me! My cock was hard as iron and even.
