If I walked in and found you like that I'd I run my hands up and down your inner thighs, just barely brushing against your pussy lips repeatedly then use my hard cock to spank your wet inner lips back and forth and up and down, teasing your clit over and over again, until your juices coat my cock and are running down your legs and you are shuddering and shaking.
When I am good and hard slide my cock in, just the tip and hold it there, then in and out, in and out, eight or ten times, then with one long deep thrust give you every inch I have til I'm buried balls deep and you can feel my hard fucking cock head on the back of your belly button. Once you have caught your breath I begin slowly to stroke in and out, with ever increasing tempo, longer, deeper, faster, harder. I'll take a handful of your hair and face you towards me and make you look in my eyes and say to you " Cum for me, cum, for me over and over. Your pussy clamps down hard on my cock and you scream out "I'm cumming, I'm cumming, I release a flood of my hot sticky gooey mess deep in your belly. Still inside you, you reach down and gather two fingers full of our mixed juices and bring them to your lips for a taste of us together.

lovely cock, with a beatiful head
mmm I agree totally! two cocks inside the one pussy filling  up every last little part of her, rubbing all over inside her and also all over her clit and lips -  the sensations drive her crazy! Is also wonderful feeling your cock rub against the head and shaft of the other. It is like a warm wet hard hand wanking your cock all over and when that other cock cums the feelings are awesome. The hard jerks followed by the strong pulses all along the length of your cock feel wonderful then the heat and wet of his cum filling her up feels simply fantastic. For the women having two cocks cum inside her at the same time is a feeling almost beyond description. Wish could be there with you two enjoying such wonderful fun and times together mmmmm

I want to take you into the livingroom and open the curtains on the front window. So the whole neighborhood can watch as you get on your knees and take all of my cock in your mouth and I grab the back of your head and pound your face long and hard. Cars stop in the street and people get out to watch your gorgeous face devour every inch of my meat.
Then I pick you up and face you out the window and plow your dripping wet pussy from behind with my long stiff tongue as your tits press up against the cool glass. You beg me to take you now and as the neighbors watch as I take your right leg and lift it onto the window sill so your pussy is spread open for me to insert my cock all the way into your steaming pussy and fuck the shit out of you. Then pull out, push you down and cover your face and tits with a bucket of my hot gooey cum. The audience applauds.
