The day came for my sister to go to the prom and she ran around the house like a crazy person...ironing her dress, getting her hair & nails done...all the typical things a girl does before a big dance. As she was getting ready, I couldn't help but stare at her as she ran around the house in her little tank top & cotton short panties. I had never given her body a second thought before but today was different...she looked so cute & so hot all at the same time. I felt my cock give a little twitch when she bent down on the floor looking for her hairbrush. I tried to look away, but how can you turn your eyes away when a hot teen girl is bending over in front of you wearing practically nothing?! I got up & went to take a shower, thinking that the cool water would dismiss any more of those thoughts.
While I was in the shower, I looked down & noticed that my cock was still a bit hard. I figured that I was going to have to do a quick jerk-off since the cool water wasn't helping it any. I soaped up my hand & started to stroke myself when all of a sudden, this loud banging on the door startled me.
"MARK!"
"What?"
"Mark...I need to get in there...all my stuff is there & I have to get ready."
"Give me a minute...I'll be right out!" I figured my jerking off would have to wait so I started to rinse off when the door opened up & Megan walked in.
"Megan...couldn't you at least wait until I got out?"
"Mark, I have to get in here...besides, it's not like we haven't seen each other naked before."
"Megan...we were like 6 & 3 at the time...it's a little different now," I said as I shut the water off & grabbed a towel.
I looked at her bending over the sink trying to apply her makeup. Damn, her ass looked awesome in those panties.
I cleared out of her way, went to my room, got dressed & headed downstairs to eat dinner. Mom had to go out for a while and Dad was still away on maneuvers so it was just me to send her off on her big night.
At around 7:30, my sister came downstairs...she was a vision! Her hair was up but it had a few strands hanging down the sides. The navy blue satin dress she wore clung to her body and her shoes made her at least an inch taller. She was stunning!
"Damn Meg...you look beautiful!"
"Do you think so?"
"Oh yea...you're a hottie!...every guy will be looking at you tonight!"
Megan smiled..."Thanks Mark...I kind of feel sexy tonight!"
Since Mom & Dad weren't home, I took it upon myself to give her the whole sex-talk thing...making sure that she didn't go too far & that no means no...that kind of crap. She laughed & rolled her eyes & said "OK Dad!" I snapped a few pictures so we could show them how beautiful she looked.
We sat & talked while we waited for Frankie to pick her up. 15 minutes...then a half hour...then an hour....I couldn't believe it...this asshole stood up my sister! She sat there...looking at the door...tears streaming down her face...she looked like a fragile little girl that had just had her dreams shattered. I was going to kick Frankie's ass but first, I had to take care of her.
I ran upstairs, stripped down, threw on one of my blue suits and slipped out the back door. I took some flowers from the garden and walked around to the front of the house. I rang the doorbell and as she answered the door, she burst into tears.
"Hi..I'm Mark and I've come to take you to the Dance!" I said...trying to make it as real as it could get at this point.
