to take care of things for you.” Robert then placed the large red vibrating dildo on the wooden, straight back chair from the kitchen. The suction cup held it in place standing straight up. Its size was intimidating; or accurately frightening. “Baby, that’s not going to fit inside me.” I was clearly alarmed, in fact, I was scared. "Mom, you have taken all of me. I am that big.” I looked at the two inch thick, big red dick sticking eight inches above the seat of the chair for a moment, and I turned to my son and said, “No baby, I don’t think you are. You are a very well endowed man, very well endowed. But son, that thing is huge. I am not a big woman. I think we need to start out with a toy that is a little more reasonable in size.” I realize by calling Robert ‘son’ instead of ‘baby’ I was taking a more serious, more authoritative tone. For a moment it dawned on me, that I never took this tone to discourage Robert went was first trying to seduce me, and get in my panties at the beginning of the summer. No, at that time it was ‘baby, we can’t do this…..’. I guess I never did try to dissuade him from pushing forward at all, did I? But now I had a more immediate and urgent problem, I did not think I could accommodate that huge toy in my rather tiny pussy; and if I did, my pussy might never be the same. “Nonsense,” Robert said with confidence. “This will fit just fine.” And Robert twisted the base of “big red, it started to buzz loudly.

I really mean it. This is for you. Honest.” Okay, this was important to my son; so I decided to give it a go. Hell I have never been able to say 'no' to Robert and stick with it on any subject. I squatted down and removed the diaphragm, and placed it end table next to the couch. The large volume of spermicidal jelly remaining in its concave belly. There was still a fairly large volume of spermicidal jelly up inside my belly as well. Robert handed me a tube of K-Y jelly. "Here mom, put some of this on your inner lips. It will help you take 'big red'." I never had to use artificial lubrication before. Certainly not with Robert. Robert has had my pussy gushing all summer. But looking at the size of large red phallus buzzing on the chair, I decided I need all the help I could get. I squeezed a large dollop of the clear gel on to my finger tips, squatted slightly and placed the lubricating gel at the opening of my vagina and up inside me. I handed the tube back to Robert, took a deep breath and took a few steps towards the very intimidating toy on the chair. But as I approached the ...
