On her face/In her mouth

Just as you feel you're about to explode you pull your cock out of her pussy and position yourself so that your knees are either side of her and your balls are rubbing against her big tits.
"Open your fucking mouth,slut" you command,which she does eagerly.
You feel your cock twitch and you let loose a torrent of hot white sperm straight at Penelope's face.
A huge explosion of cum splatters all over her,on her chin,her cheeks and in her hair.
She tries to catch as much as she can in her mouth but there's so much of it it just goes everywhere.
As the last spasm wracks your body you look down to see this beautiful actress covered in your hot juice and smile to yourself.
She swallows what she managed to catch in her mouth then licks her lips clean before asking "So,do we have a deal?"
