Stop! I think you're horny enough to know what a blowjob from me feels like.
I always start with a guy's balls, they need attention too. Take your lubed up hand and massage your left nut. Gently squeeze and pull on it. Imagine me sucking on it, using my tongue to play with it. Do this for a minute and then switch to the right nut for another minute.
Now grip both balls at the same time as I take your whole sack into my mouth. I do this for at least two minutes before moving on.
