So I almost killed my best friend last night.

My best friend and I have been friends since 2011 he lives about 1.5-2 hours from me and we have feelings for one another but can't make the next step toward a relationship because of the distance, well just started having sex last year and discovered that 69 is our favorite number 😜. 
Anywho, he's been asking me to squirt in his mouth for awhile now but I've been afraid to, well last night... it happened and he was literally drowning! OMG when I tell you I was scared, I freaked TF out but couldn't move because he was holding me. 
Has anyone else had a similar experience?
P.S. I LOVE him but he just refuses to consider trying the LDR thing although the drive is nothing for me, when he came to my graduation and to christen my apartment he made a big deal out of the drive.
