Suck them

I reach behind her and grab her sweet ass, pulling her towards me. She gasps as i attack one of her tits with my mouth, first licking it all over then sucking it into my mouth.
"Mmmmmmm, that feels so good" she says as she grabs my head and pulls me into her, running her fingers through my hair.
I suck her left nipple back and forth deeply into my mouth, as my hand finds her other nipple and begins to pinch it and roll it in my fingers. She gasps at the unexpectedly intense pleasure I am giving her.
"Oh wow...that feels so good" she says, her breath getting more shallow as she nears an orgasm. "I...I think you're going to make me cum! Just from sucking my tits...wow!"
This urges me to work harder. I grab her right tit hard, pinching her nipple hard as well, as i suck her left nipple furiously. As she begins to moan and pant, close for sure, I begin to nibble her left nipple, finally with one hard bite, and that's all she can take.
"OH! Oh yes, oh my god i came! Damn you're good" she says.
I release her tits and lean in to kiss her. Great tongue."
"Mmmmm, that was amazing" she says, between kisses. "Now i need your cock!"
