Some strange lotions.

'First, I'm going to put these lotions on you." Vanessa said. Lauren looked up at her sister in confusion. Lotion? She figured her sister would be out to humiliate her! What was humiliating about lotion?

Little did Lauren know, Vanessa had a trick up her sleeve. There were no ordinary lotions. She'd taken them both from her mother's house. They were expensive, rare cosmetic lotions.

Then, Vanessa switched to the skin loosening lotion. she squirted this on her hand then started rubbing it onto Lauren's small stomach. Lauren sniffled a giggle as her belly was rubbed until it shined with lotion. At this point she felt something strange in her chest. A tingle. A slight stimulation. What was happening?
