You wanna fuck Natalie's tight asshole

As you turn towards Natalie she begins to breathe rapidly and nervously.

"It's alright sweetie. Just relax. I'm using plenty of lube and I'm being careful, so it's nothing like in porn."

That appears to comfort her, and when you position yourself behind Natalie, she's way more relaxed than Emma was.

The first couple of thrusts are as tough as with Emma but Natalie is tall and generally larger than the slim Emma. This includes her anus apparently as she's not as tight as Emma.

It doesn't take long before you're as deep as you can possibly go. Natalie has stayed quiet for most of the time, but now that you're thrusting in and out of her tight asshole she opens up.

"Oh my god James!", she bursts out. "I'm close... I'm gonna fucking cum with your dick deep inside my ass!"

The vibrator in her pussy is at maximum speed and when you give her right asscheek a playful slap she buries her head in the bed and screams her orgasm into the soft material of the bed.

You don't want to cum in Natalie either as you're saving it for someone special. Deep down inside you know that it's Kimmy's ass you want to pump full of your cum, but Mary or Emily wouldn't be so bad either.

You look to your left to find Emma shaking from another orgasm. She's watching you pull out of Natalie's ass with a hungry look and her eyes are dreamy. You call out for Liam to lower the speed on Emma's vibrator but Liam is very busy with Mary.

"Yeah Liam. Cum all over my big titties you naughty boy.", Mary says to him. Shortly afterwards, her tits are indeed covered in his fluids and you turn away from the scene grinning.

You decide Emily is next and perhaps it's time to cum in someone's ass.
