I thought I would share with you guys one technique which really gets me off. If you have an average sized dick about five and a half inches or so this may prove to be a mind blower for you. Find an old plastic bottle that spices come in, you can find these kind at most supermarkets. Dump out the spice or wait until it's empty.. I searched our spice cabinet until I found one which fit my dick and not too loose. I inserted my dick when it was soft. As I got hard my dick would fill in the space. Then I took it off and sanded down the inside opening to eliminate the rough edge. That way I would feel only the smooth inside of the bottle. Then I would put a hole at the far end. Now comes the fun. I put lube on the inside of the bottle, slid my soft dick in and slowly pumped. As I stroked back and forth I used the hole to create suction. My God did that feel good. Just like getting oral sex, however I can control how much sucking I like. I always cum like crazy. What makes it nice is that my cum ends up in the bottle for easy cleanup. Especially if you put the hole on the bottom top of the container. After you wash out the bottle you can put the plastic snap cover with the holes in it back on and no one will know what you use it for if you live in a household with others. This objects works real good for us guys with average to small dicks. Sorry big guys. Oh also, if you guys want added fun, here's what I sometimes do. I lube up my bottle, then I lube up the middle finger of my other hand. I kneel on the floor and lean back on my heels. I shove that finger up my ass and wiggle it while stroking the bottle on my dick creating various suction strengths. The tickling of my asshole plus stroking produces ming blowing cums. Thanks for letting me share.
