First Lesbian Experience

It was my 18th birthday and a few girlfriends and I went to celebrate. While we were eating dinner, my best friend (who had a boyfriend) kept leaning over the table and touching my thigh and even holding my hand. I didn't think anything of it, we are always affectionate with each other as close friends sometimes are. She drove me home and spent the night. We laid in the same bed and after a while i opened my eyes to see her hovering about me. She then kissed me out of nowhere and moved down my neck to my stomach placing kisses up and down my body. It felt so good, i was in shock, not wanting her to stop, yet at the same time she was by best friend and both of us are straight. I then felt her hands reach under my panties and slowly rub my pussy. I was so wet that she easily slid two fingers inside me while licking and sucking on my clit. Before i know it we had flipped over and i was now riding her face until eventually I came all over her tongue. She smiled at me and we made out, falling asleep in each others arms. Now 5 yrs later, she is my best friend with benefits, we play with each other often. Matter of fact, as you're reading this, she is asleep next too me now, having just ate out my pussy again.
