My Boyfriend and I Sharing a Room With My Brother and His Girlfriend Leads To Sex Part 1

My brother, Mark, and I always had a good relationship. As we got older, we became more like friends. He's only two years older than me. He moved away for college but I stayed at home.

After he graduated, he moved back home and we started to hang out together. Once I started dating a very good friend of his, our social circles got even closer.

I was twenty dating his friend and my brother had a girlfriend at the time too. We planned a trip during the summer to the beach that included my boyriend, Trent, my brother and his girlfriend, Lisa. To save money our early 20 something broke asses decided to get one room with two beds.

The first day we went down, we went to the beach, freshened up and went out at night on the boardwalk. Of course we stocked the room with snacks, food and alcohol.

That first night after when we shut the lights out, it didn't take long to feel my boyfriend's dick pressed against my ass. We were spooning and I grinded my ass up against my boyfriend's hardness, feeling naughty that we were teasing each other while my brother and his girlfriend were sleeping in the other bed. Trent got more daring by slipping his hand underneath my shirt and played with my nipple.

I did my best to stifle my moan but it got a bit more challenging when he slipped his hand down to my wet pussy. Spreading my thighs, I gave him easier access. I was so aroused and needed to be fucked so I turned on my back and we began to make out. My hand found its way on his dick and I stroked him as he fingered me.

Eventually Trent found himself in between my legs with his boxers pulled down. I spread my legs wider and lined him up to my pussy. He pushed in slow and as if he was trying to be careful not to wake up the other couple in the bed right next to us. I wrapped my legs around him, loving how my boyfriend thrusted slow and deep inside me. I bit my lip so I wouldn't moan my pleasure.

I was startled when I heard a moan come from my brother and his girlfriend's bed. I was so focused on my boyfriend I hadn't noticed there had been shifting of bodies on the other bed. It was dark but with what little moonlight came through from the slit in the curtains from the window, I could see bodies moving on the other bed. A movement like my brother was fucking his girlfriend.

Trent moved faster in me, probably turned on just as I was knowing other people were fucking too. I didn't go crazy with my moans, wanting to still he somewhat discreet. However, our room was filled with soft moans, some from me and others from Lisa, and skin up against skin.

I could hear my brother grunt as he came in his girlfriend. Hearing my brother cum had me excited and is what sent me over the edge and had me coming hard all over my boyfriend's cock.

After a few minutes Lisa got up to go to the bathroom and then I did the same after she went back into bed.

The next day the four of us didn't mention how we all fucked. The rest of the day went as normal. However, at night the same thing happened. After the lights were off each couple fucked but still acted as if we were being discreet.

As the trip went on we became much less discreet.
