Baby, You Can Drive My Car!
Grab that string I used on you earlier. I want you to wrap it once around the base of your cock and once around the top of your nut sack. Tie it tightly (but not too tightly) and then lube up that engine of yours and take it to 5500 RPMs.
Let me tug on my bra a little to help you out. You can almost see my right nipple this way, but not quite. Can you imagine what that cock would feel like in between these two huge breasts. They're all natural too. I've had them since I was 15. You should have seen the attention I got in high school.
Whoa now. Keep that dick of yours at 5500 RPMs, but don't stop stroking. Just slow down if you need to. I'm just starting to break you in.
Can you picture what it would have been like to be one of the boys in my class when my breasts first got this big? I bet you would have been one of those creepy guys who just stares and never gets up the nerve to come talk to me. That's why you grew up and bought yourself this sweet ride. You're compensating for how pathetic and inadequate you really are. Your macho act never fooled me for a second. You're such a sad little man. Look at you so helpless right now. You are in my complete control. You will obey my every command. You have no choice.
