How did I come to be standing in the bathroom, in just my boxers, smoothing self-tanning lotion on my pretty sister's back? Did I mention she was wearing only g-string type panties? Oh yeah! She was. Well read on. I'll tell you all.
Susan is my sister's name. She had just turned eighteen at the time, me too; I'm Solomon. Obviously we're twins. We were in our final year at high-school and our parents were taking us on a two week holiday in the mid-year break. It was the last day of school, then the next morning we were to fly out, so Susan and I were excited. Here in Melbourne Australia, mid-year is mid-winter, which may seem strange to Northern Hemisphere readers. Our holiday destination, the Gold Coast, is 1600 km or 1000 miles closer to the equator than our home and mid-winter there is mild, warm and sunny making it Australia's most popular beach resort. Susan wanted to look her best at the beach, so she had purchased a large tube of self-tanning lotion and two new bikinis.
We usually got home from school about 4:00pm, and our parents, who back then owned a sportswear shop, didn't close up til 5:30pm, then battled the traffic for an hour to arrive home about 6:30, stressed, tired and irritable.
Susan was so desperate to get her tan going, she reluctantly asked for my help. "Solly, um, d'you reckon you could help me with this...tanning stuff? I can do my legs and that, but I can't do my back. There's plenty enough for two if you want to use it as well."
"Yeah...okay, let me read the instructions."
"No need for that, smarty, I know what to do. Come into the bathroom." She said, crankily.
In the bathroom Susan sat down on the wooden chair, took off her shoes and socks, pulled up the skirt of her checkered school dress and began rubbing dollops of the tanning lotion into her legs. She had great legs so it was a turn on, but none-the-less I asked, "What am I here for?"
"I'll need you to rub the stuff on the back of my legs in a minute," was her grumpy reply.
"If you are gonna be so...annoying, I'm not helping."
She looked up meekly "Sorry Solomon, I'm a bit...whatever...about asking you to do this, but Mum will be busy and rushing to get ready for the trip."
"Right. Okay then, if you've finished doing the front of you legs, you need to stand up for me."
She stood with her back to me.
"Um, no good, I can't see to do it. Stand on the chair."
She climbed up on the chair and bending forward a little, held on to it's back. I squirted lotion into my hand and started rubbing it onto her shapely calves. I was really getting turned on so I looked up at the back of her thighs, then found I could look right up her skirt. I'm sure my eyes bulged out at the sight of her round, pantie clad bottom cheeks. My cock certainly did.
"Solomon! Stop looking...there." Susan whined.
I laughed, guiltily, "Oops. Sprung. Sorry."
"So you should be, and don't get that on my uniform, it probably stains."
"Now you tell me. It'll be near impossible not to. So...then, how are we going to do higher up without staining you dress?"
"Aww...I'm gonna have to take it off aren't I? She moaned. "Embarrassing! You seeing me in my underwear!"
"Oh, don't fret!" I reasoned, "You'll be more covered up than in your bikini."
"It's different," she muttered, pulling her school sweater then the dress up over her head and throwing them into the bathtub.
