Arrive

We both get out of the car and I leave my new book in the glove compartment so no one will steal it.

Cassidy teasingly says. "Afraid of bringing your book inside?" She knows how my sister gives me shit for sticking my head in books instead of pussy.

"Yeah, something like that." I put my arm around her shoulders and pull her closer to me as we walk to the door. I ring the doorbell.

It take a few moments but I hear someone running to the door. The door swings open and it's my sister Melissa, she is wearing a very small red string bikini and soaking wet like she just came from the pool. "Mike! How are you doing!?" She pulls me in for a big hug and her giant D cup tits press up against me. "It feels like I haven't seen you in forever!"

Not that I want to fuck my sister but I will admit she is hot as fuck. She is two years older than me, which makes her 24. She was one the slutty girls when she was in high school but has since slowed down. She always thought that I could have had a better dating life it I didn't hang out with Cassidy so much. Don't get me wrong they get along great but Melissa always saw something in me that I didn't see in myself.

"Yeah I guess it has been a long time. How are you doing?" I start to feel my cock get hard and start pressing into her thigh.

Melissa pulls away and looks down at what she did to me and gives me a quick wink. "I'm good. Well you know how work is." She spins a 360 around. "And I've been going to the gym and I almost fit back into the stuff from high school." I guess I was looking to hard and Cassidy gave me a nudge and gave me a look like 'behave yourself'.

I enthusiastically reply. "Shit, you do look good." Cassidy gives me another nudge.

Melissa pulls Cassidy in for a hug as well, shaking herself and Cassidy playfully side to side. It have me an opportunity to take a look at Melissa's ass and of course she is wearing a g-string bottom.

Fuck tonight is going to be hard to behave myself.

Melissa jumps up and grabs both of our hands and pulls us up stairs into her room. "Cass I have a swimsuit that you will love. and we might have a pair of shorts for you Mike." Melissa hands me a pair of guys shorts that will be a little big, but they should fit fine. She hands a small ball of clothing to Cassidy. " Here, these should look great on you." I turn around and slide off my pants and boxers to put on the swim shorts. They are definitely too big but I'll just have to be careful that they don't fall off. I start to turn around and Melissa Grabs me by the shoulders and forces me to face the same way. "Not yet. Cass isn't ready yet." I wait a few more moments and Melissa turns me around.

My jaw hits the floor. Cassidy is wearing basically 2 small triangles that don't even cover her areolas properly and a strip of fabric that just barely cover her pussy lips. "I look so fucking hot don't I?" She takes a step towards me. "And check this out!" this turns around to reveal her backside. the middle string splits right after her pussy and kinda goes around her ass cheeks. If she were to bend over we would be able to see her asshole.
