Injection into my genitals

I get an injection of saline solution in my foreskin. My foreskin swells as a result and it becomes much more difficult to pull it all over my glans. Thanks to Tim for helping me with this, I probably wouldn't have dared to do that alone. You were very tender to my cock, the sting was painful, but when you filled my foreskin and I could watch it swell in your hands, it made me very horny. Also how you thoroughly rubbed the liquid in my foreskin... I hope we will do it again soon, but with much more saline solution! I want my foreskin to swell completely!
