I just slept with my sister.

[unazed]

I don't know if Dlang.org is the right place for this thread, but 
I honestly have no where else to turn because this situation 
directly involves my family, and friends.
Let me start from the beginning, I am 18 and my sister is 21. I 
just finished high school and my sister is home from college. I 
guess this year her grades started slipping or something, because 
I walked past her room and she was crying. I walked inside her 
room to ask her what's up and she hands me a letter - apparently 
she's up for review by her college for dismissal. I feel kinda 
sorry for her so I gave her a hug and one thing led to another 
and we started making out. This is really weird because I've made 
out with girls before, but my sister blows them all out of the 
water. In the back of my mind lies the fact that she's my sister 
and what we are doing is sick and wrong, but I guess my sister 
has more experience and it felt so fucking good.
Here's the dilemma - after making out, Karen started taking her 
clothes off and she started pulling my pants down. I'm like, hey, 
what are you doing? She's like, oh come on Jordan, aren't you 
even a LITTLE curious? I felt bad because its true, my sister is 
a hottie and I always wished that she wasn't my sister. I've even 
gone as far as to fap to thoughts of doing her. She then said 
"For tonight, let's not be brother and sister. I really need this 
because I feel like shit right now and our parents won't be back 
till late and we aren't going to tell anyone.

I pretty much just fucked my sister. No, to be more honest, I 
just lost my virginity to my sister. My question is: WHAT THE 
FUCK DO I DO NOW?? What do people usually do after they fuck 
their sisters?
