So it was the last day of spring break and me and my friends had decided to chill next to the pool again. We'd done other stuff during the week but we always seemed to end up here. Within all this time my brother seemed to take a slight interest in Piper.

"So where are Dan and Tyler today?" Sally asked putting down her magazine.

"I'm not sure but they'll end up here at some point, they always do." I answered. Just as I spoke the back garden doors opened.

"Hey girls, sunbathing again?" Dan asked as we all looked at the two boys.

"Yeah and what have you guys been doing today?" I asked.

"Just been with the team," they walked over and sat with us, Dan on the end of Piper's sun bed and Tyler on mine, "you alright Piper? Dan asked.

"Yeah fine, you?" She replied as a blush made an appearance on her cheeks.

Before Dan could reply Tyler spoke up. "Hey man is it ok if I go make a phone call it's important? He said standing up and readjusting his shorts.

"Sure man, shall we go for a swim girls?"

"You guys go ahead, I'm going to go and get a drink and apply more sun cream." I said getting up and heading inside.

Walking into the kitchen there was no sign of Tyler so I next checked the living room. Still no sign of him. Deciding he must of gone out front I went upstairs to get my sun cream. As I got closer to my room I could hear slight moans. Wondering what it was I go check it out.

"Tyler, what the fuck are you doing!" He was sat there on my bed stroking his dick with a pair of my panties.

"Oh shit, Sammy you weren't supposed to see, fuck." Pulling his boxers and shorts back up he walks towards me. "Please don't tell your brother, he'll kill me."

"I don't know Tyler, this is quite serious and a bit weird."

"It's just all week you've been wearing bikinis but this one just makes you look so hot and I couldn't help it."

I looked down at my black and silver string bikini then back at Tyler. "Well seen as it is me that's caused you this," I grab his bulge, "maybe I could help sort it?"

"Wh-what?"

I pull him over to the bed and sit him down before kneeling in front of him. I take off his shorts and boxers once again and take his length in my hand. "Wow your really big Tyler, what's this about 10 inches?"

"Erm yeah, what are you going to do?"

"This." I take the tip of him in my mouth and start to move my head up and down taking in more until I can't take anymore. I carry on just like that as I start to massage his balls and take what I can't fit in my mouth in my other hand. I can hear him moaning and it just encourages me to go faster.

"Oh fuck, Sam stop I'm gonna cum."

Instead of stopping I carry on until he cums. When he does cum in my mouth I pull away and swallow it. "See wasn't that bad now was it?"

"No but your brother can never find out." He says pulling up his boxers and shorts once more.

"How about a deal?" I ask

"What deal?"

"When either of us gets horny we call the other, call it a booty call and if one of us does anything other than kiss another person the deals off?"

"I don't know Sammy, I'm your brothers best friend."

"You weren't saying that before when I was sucking you off, come on it'll be fun."

"Fine, give me your phone so I can give you my number."

I pass him my phone and he gives me his. We enter our numbers into each others phones before swapping them back. "Well I best get back to everyone." I say before walking away.
