you don't notice the spectator.

Britney pants "John, I'm coming." And she wiggles herself lose from your grip and tongue. She lowers her skirt back to normal and sits down in front of you, so she is more or less in the same eye-level as you.
"I want more, John." She pushes you backwards, so that from the kneeling position you move into sitting on your butt with your legs forward. You realize that your cock is still open in the wild, your pants are still around your ankles. And even though, you have given oral to Britney, your manhood is still hard.
Britney takes of her T-shirt and her perky tits show aroused pointing nipples. She then moves on your lap, and pushes them into your face.
Still aroused and in the routine of sucking your put the left nipple in your mouth and with your hand you want to squeeze her breast while you apply pressure with your mouth. But Britney pushes your hand away. "No, touching." It surprises you, but you don't mind, you just suck harder on her nipple so it will stay firmly in your mouth, while your tongue is licking the tip that's caught in the inside of your mouth.
"Ah, John, you are so good with your mouth. Your tongue is majestic."
Then she wiggles some more and suddenly you feel her hand on your cock. "I want you inside me." Britney moans.
And your hard cock is skillfully directed by her hand into her moist vagina.
"Oh, Christ. Britney you feel so good."
She put her left hand over you mouth and pushes you back. So you lie down on your back.
And she starts riding you. Her ass moving back and forth, back and forth. "Yes. you like that, eh. You love it when I take control and ride you."
"Yes. yes. God. Yes." you stammer.
And she keeps on moving up and down on your cock.
