Britney's first.

Dan was laying on his bed, slowly jerking his cock to keep it at its maximum height as he waited to see which of his extremely sexy step-sisters would be the first to take up the offer, he didn't have to wait long as Britney's cute yet incredibly sexy face peered round the door.

"Hey Brit, come on in!"

"Hey Dan, HOLY SHIT!"

Britney's mouth fell open as she caught sight of Dan's big cock for the first time. She could feel her mouth and pussy watering at the sight of it. She undressed almost on auto-pilot, revealing her pert and perky b-cup tits, her smooth flawless skin and her hairless pussy. Dan's cock twitched at the sight of his next "victim". Britney smiled as she crawled onto her step-brothers bed, before hovering over his cock and giving it a few licks, before giving him a slow blow job.

Dan smiled at what Britney was doing, but he wanted to feel her tightness surround him, gently guiding Britney onto her back, Dan started to explore his prey's body with his tongue, making note of Britney's erogenous zones (her neck, just above her breasts and her puffy nipples) before making his way down to her pussy.
