Tanning oil

"Would you give me a hand?" Cindi said as she held up a bottle of tanning oil adding, "I got this on Alpha 12. It's supposed to increase the body's absorption of Vitamin D and help with an all over tan."

"Sure." Adam said eyeing the bottle Cindi held in her hand realizing she wanted him to help her put it on. The idea that he was going to rubbing the slick oil all over his sister's voluptuos body was really exciting him now and he began to worry about how much self control he really had.

Cindi handed the bottle to her brother as she tied up her long blonde hair above her head.

"You know..." Adam began with his eyes still locked on Cindi's nearly naked body standing next to the tanning bed, "if we really want to get an all over tan we should probably take off our swimsuits and tan in the buff."

"You mean....naked?" Cindi squealed in surprise at her brother's suggestion.

"Sure, why not?" he said, "It's just us afterall. No one else is around."

"Ugh...I don't know." Cindi said looking over towards her shirtless brother and felt her sensitive nipples getting hard, "We are brother and sister."

"Yeah it's not like we're strangers or anything like that." Adam told her, "What could be more natural? Besides no one would ever have to know. It would be our little secret."

Adam's horse size cock was now throbing with anticipation as he wondered whether Cindi would actually take off her string bikini.

The busty 18 year old bit her lower lip as she considered what her brother was saying.

Does little sis get naked before her big brother?
