I lost a bet

Never could stand football. That night for some reason I made bet with Mike after running my mouth about his team. I lost! Mike and I have been together for about six months . He is a tall slim but fit guy no mdel for sure bt cute. Istand about shoulder hight to him. Bit the three things he says he likes about me is mu long red hair handfull tits and the small bubble butt that I wiggle for him every time I get the chance.
Friday night is our date night we always put frifday to the side for one another and sometime even are able to have Saturdy night as well.
We spent the whole night drinking and having fun before going to bed and having our alone time. HMike is one of them guys that does not look like he is packing but the first time you see it your knees get weak and you wonder if your going to be able to take it.
He went home the next mornig we talked ove rthe phone Saturday and even sunday.Monday rolled around and I heard the door bell ring. Upon opening it it was Mike never before has he ever showed up unanounced. 
He wanted to spend the evening with me and watch Dallas play the forty ninners. I never have benn much into foot ball but who could complain with your man right next to you. We watched the pregame and had a few beers I began talking shit about his team. Saying that Dallas sucked and all that stuff. I had no idea what I was talking about I figured I could at least pretend.
Befoer the gane I sen he was getting a little upset or at least annoyed with me. 
  " Why don't we make a bet girlfriend?"
  "Hell why not. what you got ?"
  " If Miami wins I'll do what ever you want the rest of the night. But if Dallas wins I get what you have refused me sense we have been dating. That tight little ass of yours."
I agrreed I have not clue as to why but I did.I have never had anal nor expected to give it up. KNow I may have to with a guy that is bigger than the last two guys I was with put together.
The next two hours I was nervous but yet kind of excited at the same time. Dallas won by six points. I thought about trying to tlk him out of it but a bet is a bet.
I took his hand and led him to the bedrrom we kissed and undressed. He was hard as a rock I my self was getting a little turned on.  
  "Please be gential. you know my ass is a virgin ass."
  " I will sweetheart I promise."
I went through the dresser and found a bottle of lube and handed it to him. m hands were shaking it was if I was a virgin once agin fixing to have my cherry popped. I climbed up on the bed onto my knees. He kissed my lower back and rubbed my right cheek then my left. 
 I felt the coll sinsation of the libe dribble down my ass crack. his strong hands rubbing it his middle finger running circles around my tight rosebud.
 Then I felt his large head slip between my cheeks and softly press against my tight opening.
  " just relax baby just relax."
He pressed a little more then the pain hit he popped in me it fet as if a balloon just pepped inside my ass. I let out  muffled scream with my face barried in the pillow. After a few minutes the pain subsided and the pleasure began I began to enjoy the filled filling of his large cock deep inside me. My hips pushed back against his thrust. my moans where louder My hand fell between my legs and we both came at the same time. I felt every drop every squirt he releast inside my tight ass.
