Maybe a flogger

"Uhh hey. Me and my girlfriend have been getting into more... kinkier."

The woman nods. "Cool. What are you into?"

"Well... Uhh, I did spank her this one time and it was kinda hot."

After a playful giggle, the clerk says "Well, have you ever tried a flogger?"

"No."

"That'd probably be the best beginner toy for impact play."

"Sounds good to me."

"Alright, come with me."

You follow the clerk to your destination, sneaking a glance at her plump rump as you do so. At the right aisle, she hands you a box that reads 'Shade of Grey Basic Flogger'. As you look at the box, you picture having Adela bent over, ready to be flogged by her 'Sir'. You feel your cock stiffen whilst you lose yourself in a daydream.

The clerk then breaks you out of your pondering. "So, is that what you're looking for?"

"Perfect. Yeah, uhh... do you have a bag?'

"Sure do."

$20 later, you walk out of Love+ with your new flogger, and a raging hard-on fueled by your perverted thoughts.
