After taking a piss and using some mouth wash Mackenzie met her friend Taylor at the back of the house in the nude.Taylor is a sixteen year old girl,shorter than most girls her age but makes up for it on the soccer field and love's to fuck!"Hi Tay,come on in."Mackenzie said to her friend.Mackenzie and Taylor hugged and kissed,oh the things girls do when guys are not around!A few minutes later in Mackenzie's bedroom Taylor stripped out of her red warm up suit and hoodie as her bike ride over was rather cool on this spring morning."So when do I get to meet Mike?"Taylor asked Mackenzie as her pussy was getting wetter."Soon,I sent him an email Tay,Ryan want's to fuck you."Mackenzie said she got back into her bed.Brendan walked into the room naked as the day he was born."Nice cock Brendan!"Taylor said as she looked at the boy's rock hard cock.

Taylor must have came three times as Brendan fucked her,a fact that made Mackenzie horny as hell.Mackenzie thought about the last few years,Friday night football games,dances,history class and getting on the bus to play East Garland High in a must win soccer game.The one thing that stands out the most is all the during the school day.At Hawthorne High certain rooms are used for sex at certain hours.As a freshman Mackenzie had her first male teacher within the first few weeks of the school year.Now as a senior all Mackenzie has to do is grab a hot freshmen boy.How many times has Mackenzie come home from school after getting fucked by two boys during the day and thought nothing of it? Brendan was getting close as he felt his balls were about to explode.Taylor begged for more as Brendan gave her his all."Uh,uh,oh I'm gonna cum now....OH BRENDAN!!!"Taylor was loud,and good thing no one else was in the house as Mackenzie leaned over kissed Taylor,"Welcome to the family sis."Mackenzie said to her friend.Mackenzie then ate her brothers cum out of Taylor's pussy as Brendan soaked it all in.About ten minutes later Mackenzie spread her legs for Brendan and said"Show how much you love me little bro."
