Basically (ok, here goes), I sucked off my brother after getting naked and kissing/groping together.
We were sharing a hotel room for the weekend last week because of a cousin's wedding. It was after the reception, we were both a little tipsy and happy and had been dancing and celebrating with friends and family all afternoon and evening.
When we got back to the room it was late and we were just chatting about how nice a day we'd had. I said something about wishing I could have a wedding like that someday and he caught me off guard by telling me how sure he was that I would because of how sexy I was. He apologised immediately and I felt bad for him so told him thankyou for being so sweet.
For some reason I walked over and gave him a peck on the cheek. He looked at me after with the exact look a guy gives when he wants a girl, and for some reason I didn't pull away. I was waiting to see if he was gonna do what I thought he was gonna do- kiss me.
He did.
And I let him.
It was long and passionate and the most forbidden yet lovely thing I'd ever done. We eventually started fumbling and lay down on the bed together with our arms wrapped around each other. We didn't say anything. We just kissed, and began taking off each other's clothes.
If anyone has told me that at this wedding I'd be having my breasts sucked on by my brother as he fingered me, I'd have retched and then hit them. But that's exactly what happened and it made me cum three times in a row which I've never done before.
That was the point that I just slid down the bed and took my brother's penis into my mouth and gave him only the third ever blowjob I have ever given in my life. I even let him finish in my mouth and swallowed (never done that before).
After that we sort of just spooned and cuddled until we fell asleep.
In the morning we barely looked at each other and it's like there's just an unspoken agreement in place since then that we never speak of it again.
I can't believe this happened and I have literally NO idea what to do now.
