My grandma has always been friendly and love giving hugs when I see her. She is little on the heavy side with big boobs. I don't care I love hugging with those large boobs squeezing my chest. One day I took it little farther when no one around and when she give me a hug I squeeze her butt instead having my hands on her back. She didn't say anything but hugging me tighter. I figure she like it and I give her big kiss in the mouth and wrap my legs around her legs. She felt my hard dick on her legs and said, sweetie you got a boner, I smile and said would you like to have it? She grab it and stroking it and I am rubbing her bush pussy. She said we need to continue this but not here, everyone is here we have to go some place. She make up a excuse telling everyone I need to take her to the store she had forgot to get for dinner. Grandma love cooking and does a good job at it. On the way to the store she was giving me a blowjob. I didn't know she like to swallow. She swallowed my load of cum and said she wants to get fuck. I had to find a spot where no one is around. I found this spot had grandma in the backseat and I was fucking her. I was pumping her and she was moaning the whole time. When I was ready to cum I push my dick deep inside of her bush pussy and just let it all out. She said sweetie you filled up my hole and is dripping out. I told her I was sorry and she said no need to be I love feeling the warm cum deep inside. She use her panties to clean herself up and handed to me to keep for memory. She was walking around the entire day without her panties on. We did when into the grocery store and got what we want and went home.
