He swapped me (25F) and i got railed, hard.

So my BF has always been competitive. Easily pushed into silly bets and its all a bit stupid. Well we were at a party last week, and had a few drinks. I started talking to a girl that i hadnt met before. We were chatting away and it wasnt long before our BFs came over. I saw my BF check her our, at the same time as her BF looked me up and down. Well it wasnt long before they we each complimenting us on how we look, how sexy we were. Each trying to one up the other.

Long story short, turns out they play football against each other, and my BF just wanted to get one over on him. The compliments turned to jokes around "wish my girl was as hot as yours, wish i could sleep next to that" etc, until he said "well lets swap then!". Both us girls stood there shocked. I knew already what my BF was thinking: "i am going to fuck his girl". They agreed to this very quickly without even thinking about us? fuck him. I will go along with it too. My BF led her away, this guy led me to a nearby room.

With privacy now, he got close to me and said "your boyfriend is so fucking annoying". That won be over, my tongue was down his throat so quickly it took him a second to realise. His hand drifted up my skirt, my hand found his cock over his jeans. It wasnt fully hard yet. I would fix that.

I dropped to my knees and pulled his pants down. Out flopped this semi hard monster. Way bigger than my BF and not even fully hard. It fell next to my face, and i licked it from base to tip before taking the head into my mouth. I looked up because of that sexy eye contact and realised there was a phone out recording me. I blew it a little kiss before giving my best pornstar blowjob. By the time he was hard, he was easily bigger than any real cock i had the pleasure of seeing. About the same size as some of my toys. I needed it.

I stood up and he pulled what was left of my clothes off me. I wrapped a leg around him, guiding his cock into my already wet pussy. He was inching into me with each thrust. I was already wimpering on this monster. He lifted me up, resting me on the desk next to us, and grabbed both my arms under my legs. I couldnt do anything but moan as he started to own my pussy. It didnt take long til he told me to roll over. He was a bit taller than me, so i ended up on my toes as i felt his cock between my legs. I placed the head in my pussy as I felt has hands on my hips, holding me tight as he started thrusting. I was so full. I felt his balls slap my clit. I was lost in pleasure. I felt him hook my arms behind me and pull my body up. Arms held behind me by one arm, the other playing with my nipple. I must have cum 2 or 3 times before i felt him tense up, thrust deep into me and cum.

We kissed a bit more, cleaned up and got dressed. He told me that we should do this regularly and not tell my BF. I agreed with him, too good to pass up.
