Ok, here goes a story.
I have a cousin, I-m 3 yrs older than her. She and I have been very close since always, we live a few houses away, we attended to the same school, we have no issues when it comes to nudity...
On late 2009 my uncle had a trouble with his wife and got divorced, since the house was hers, he and my cousin moved to our house. She slept in my room and used my bathroom.
One night in march 2010, few days defore my 14th birthday, my dad was working, my mom was in the living room watching a horror movie and my uncle was asleep, I was in my bed playing with my DS and she just finished taking a shower, when she came out and found that she had no clean clothes, so she decided to sleep naked.
I had no issues since we had slept naked many times before but this time something was different.
since the bed was small she was very close to me and the feeling of her fresh, humid body was making me feel "weird", then I realized I had a boner and my dick was grazing her leg.
We couln't sleep, and some time later, around 1 am, she told me "I-m bored, let-s play something", "like what?" I said..
At that moment, she got up and said "I saw something in a movie last night" she took of my sheets, lowered my boxers, sat down on my dick and said "start rubbing it"
So I did, and boy it felt so good...
we used to do that every night until one night, she finally told my to put my dick in her vagina.
We've been sexually active since then.
