I am your mate’s girlfriend and I have had a thing for you for a while.. I start the scene off saying how I really want to fuck you but not sure if yoy feel the same way.. I say how Ben really wants to get me pregnant but I don't want him to impregnate me. I want you to impregnate me. I say it's okay Sophie will never find out and it'll be our secret Then I am completely naked and riding on top of you saying how your dick is so big and that its so much bigger than Ben's, his dick never reaches my g spot but yours feels like it's in my belly filling me up. I say Mmmmm Im going to ride on top of you so you can I take more and more of your offsprings I want to grow huge with your cum all in my belly, And then I start rubbing my belly telling you how I love my big belly but I want to be so huge, my belly starts to grow as you cum (i slowly push belly out progressively like it's actually filling up) I bounce up and down jiggling my belly and telling you that I want your sperm and moaning and demanding that I want to drain your balls. I rub my big belly as I start saying how I can feel your balls draining into my belly as I take all of your cum making me grow bigger and bigger, but I demand that I want more and continue to ride on top of you taking all of your cum and my belly gets bigger and bigger and I say I just want more until I have completely drained your big juicy balls.
