For my 18th birthday I had a pretty normal day. I opened up some presents and had some cake. The only plans I'd made were to spend the next day shopping with my sister at the city she lives in. So we went to her flat to spend the night so we don't get stuck in traffic the next day.
The things you should probably know first are that she's 31 years old but still very hot. A 5F-4 high brunette with a nice curved ass and 36DD breasts. I couldn't help but fantasize about fucking her sometimes, right?
Me, I was only just 18 and bearing in mind my birthday's in December it wasn't all that surprising we got snowed in.
I was still half asleep when my sister came into the room and told me it was snowing so much we can't leave. I just looked at her; she was in a pink bath robe that was loosely tied.
"Then what shall we do?" I replied.
I was still staring at her. Her silky legs were bare and I could almost make out a lacy thong she was wearing. Her body was damp from a shower she had just taken. The thong actually looked damp as well. It was going up her slit- Yup, camel toe.
"Do me."
I looked at her in disbelief, waiting to find out if I'd heard her wrong or something. It all felt like a dream. Then she started to untie her robe. My jaw was opening up and my mouth starting to water. I realised she might just be playing a joke on me. I should at least protest a bit.
"What are you on about?" As though I didn't understand see wanted me to see her naked.
No reply. She just opened it up and let it fall to the ground. Then as she started walking to me from the door.
"You make me so wet. All hot guys do. I'm still a virgin you know; and I know you are too so let's have sex. Just once if you want- it can be my little secret birthday present to you."
My mind felt like it was going to explode. I looked up and down her body, openly scanning her now. My big sisters body is perfect. Her nipples were hard and I could see them popping up through her matching white lacy bra.
Then I got up out of bed, in my boxer shorts I walked over to her and grabbed her hand. I placed it on my tenting boxers and she wrapped it around my cock. She was breathing deep and so was I. I could feel her hand tensing and then unwrapping itself from me. I looked down at her face and a cheeky grin emerged. Her hand sunk under my shorts and each finger slowly started to enclose around me again. Tighter now, without any clothes between her and me.
