She rides you

 "Here" she says as she pushes you down.  She puts her hands on your stomach and starts to bob up and down.  Oh god it feels so good.  She looks amazing too.  You have always enjoyed the site of breasts jumping up and down.
   She sees you looking at her breasts and smiles.  "you like watching my boops jump up and down while i fuck you baby?"  you can only nod.  god, she is so tight, her pussy muscles are just milking your cock.  You move your hands to her hips to help support her.  She gets the hint and moves her hands up to her bouncing tits and starts to massage them.  "Oh yeah baby, you cock feels so good inside me."  
   You moan in delight.  Her pussy feels so good, and she looks so fucking hot, riding your dick and feeling up her own tits.  "Twist your nipples for me honey.  Hurt your tits."
   She looks at you with lust as she moves her fingers to her nipples and starts to pull on them.  "You want to watch me hurt my tits, is that it baby?  Do you want to hurt me?"
