I was in Miami for a few days on a business trip and my friend, Ben, said that I could stay over at his place whenever I was in town. He was also on a business trip out of town but gave me the code so that I could let myself in when I got there.
The first morning I walked to the kitchen in my boxers and t-shirt to get some water and that's when I ran into his sister doing dishes, in nothing but a black t-shirt and a black laced thong.
"Good morning" I said as I walked into the room, making her jump a little as she turned around.
"Sorry I didn't know you were staying over," she said. She had moved in with Ben temporarily while she was waiting to move into her new home, but didn't feel the need to get dressed since she was expecting to have the house to herself for a few days. I guess Ben had forgotten to tell her that I was in town for the weekend and had forgotten to let me know that she was also staying over since it was all very last minute.
"That's okay" I said, trying not to look where my eyes desperately wanted to look.
"Sorry for scaring you," I said. "I thought I had the house to myself."
We stood there talking for a few minutes. She told me that she had just broken up with her boyfriend and was staying with her brother temporarily until she could move into her new place.
As we talked, I kept slowly moving in closer and closer, testing the waters. I tried desperately to not allow my eyes to wander but those black panties kept grabbing my attention, making my cock hard now. It was obvious that she could see the tent forming in my boxers but tried not to make it noticeable.
When our bodies were almost touching, I slowly moved my hand and rubbed softly between her bellybutton and just above her pubic line. She wasn't pushing me away so I took it as an invitation to keep going, so I did.
I then slid my fingers slowly down her panties, until I reached her clit, already making her moan in pleasure. After a few moments fingering her, I pulled my fingers out and sucked on them for a moment, while she watched, turning her on even more.
