A surprise for boyfriends birthday

My boyfriend got a birthday treat when I invited my friend Kelly over to party with us.  She came over and sat next to me and started kissing me. I could see my b/f’s cock was harder than ever through his jeans.  Then she put her hand up my skirt and began to finger me.  I was feeling her tits and then she took off my skirt and was licking me out.  He couldn’t wait any longer and I gave him a blowjob while he watched her licking my cunt.  He came in about a minute!!!!
