Keeping him satisfied.
When my husband and I were in our mid twenties I was pregnant with our first. It was around my eighth month and I got to feeling very uncomfortable having sex with him. It may have been a psychological thing being that Mike (my husband's name) was quite well endowed. I never took a ruler to it but I know it was somewhere over 8 inches long when hard. He also was and still is one cum producing factory. I had been with lots of boyfriends and men friends before he came along and I'd never seen any of them produce the cum Mike does. I remember before we married seeing the condoms when he was finished. I was always afraid they would burst they'd be so full.
Anyway, lucky for us, when I got where I didn't want him in me anymore we still had something that he had always loved (and still does). From the first time we got together and became sexual Mike has always loved to be touched and felt between his legs. In other words; his cock. He has always loved to show it off and it is a special thrill to him to have me see him shoot off. I also get a thrill from seeing this too so it really works out well.
So, back during my eighth month when I wasn't comfortable 'doing it' we got into this. I knew my man needed to be 'serviced' as I always joke to him. We started out with him laying on his back with me on my side laying my head on his chest to I could really see his cock as I stroked it. I'd have my leg across the top of his thighs and Mike would have his hands rubbing all over my leg top and bottom as it lay over him. He always gets aroused from the feel of my legs. I'd bring him off and watch him shoot off. He loved it and so did I.
Over the years we have come up with different positions and ways to do this to him. The last bunch of years our favorite is for me to lay on my right side with him also on his right side behind me. I lean forward. I lube up my inner thighs just an inch or two below my pussy and he then lays his hard cock on there and I put my legs together with his cock sticking thru to the front. The head and an inch or so of the shaft stick thru and I lube up my fingers and use the finger tips on what is sticking thru my thighs. This drives him crazy with pleasure and it doesn't take long and I get a good show of his cum squirting all over the towel I lay there to keep it off my side of the bed.
We have been happily married now for over 25 years and we still use manual masturbation of each other quite often. As I wrote early on this man of mine loves getting good hand jobs just about as much as he does getting that other thing between my legs. And he is still a cum producing machine and I still love to see it when he 'goes off' and it takes a good hand job to see this.
