My Sister's Boyfriend

Chapter 4

I gulped..I was scared, I mean he is really hot and everything, but what if my mom or sister find out?.

"Uh, where's my mom?" I asked.

"She said she had to go do some stuff, she would be back later" he said, "now let's start"

He began by taking my shirt and jeans off, so now I was in my bra and pantys.

"So fucking beautiful" he said as he looked at me up and down.

I just blushed.

He took my bra and pantys off and started sucking one nipple while pinching the other one.

"You like that?" He asked as I moaned softly.

"Yess" I moaned out.

Alex began taking off his swim shorts as I sat on the bed and watched. He looks so nice..his dick was probably about 9.5". It was sooo huge!.

"Pretty big dick, ain't it?" He said as he stroked it a few times.

I was so amazed, I always wanted to do this with him but was too scared. He came over to me and told me what to do.

I began sucking and stroking his dick. I even deep throated it. After a few minutes of doing that Alex rolled on a condom. At that point I got really scared.

"I don't know if I wanna do this.." I said really nervous.

"It'll be fun, I promise" Alex said.

I gulped again..this isn't right, he's my sisters boyfriend I said in my head.

"But you're my sisters boyfriend..this wouldn't be right" I added.

"It'll be fine, she's sleeping outside" he said, "and besides, I always wanted to do this"

Alex ended up talking me into it and we started..

"Ok, it'll hurt at first but I'll go slow" Alex said.

We did doggy style first, so I got on my hands and knees on my bed and Alex got behind me.

"Ready?" Alex asked.

"Yea" I said.
