Suzy soon heard the sound of a rhythmic grunting and moaning. She raced upstairs to find to two people fucking on her brother's bed.
The woman had a mop of curly brown hair, was buff, had a huge rack and legs for miles she was riding a guy.
The man was buff too, he wasn't lying on his back as she rode him, he was sitting his head a few inches shot of hers.
Mike was deep inside Katie grunting as he squeezed her ass driving his cock into her pussy. She cupped his face in her hands. Her long legs either side of them biology was driving them not experience and Mike had more of it. He started to tighten his grip on Katie like a python, squeezing her body into his.
"Ah!" moaned Katie.
Her d cup breasts bounced as her body was wracked with the first orgasm of her life.
Thoughts of getting pregnant made her push at his chest in vain.
"Get it out-'
Mike replied by grabbed her buttocks and rammed his dick into her like a red hot knife, straining for release, until he hit bone.
"Ah-ha!" wailed Katie.
Each thrust drew her body closer to his as she wrapped her legs around his torso. Her arms around his neck she started thrust her hips rocking in time with her lover as the two people became one being.
"UGH!" groaned Mike blowing his load.
"Oooh..." Katie moaned.
She clung to him like a drowning person on a life raft. Her breasts jammed into his face. Her body trembling with aftershocks of multiply orgasms.
Katie's knees were under Mike's armpits as she, for the first time, kissed him full on the lips. The sheets of his small bed drenched with their body fluids. He leaned back onto his bed Katie having to grip him so she didn't fall off. Suzy came into focus looking aghast.
"Wha-What are you two doing?!?"
"Fucking" replied Mike honestly "so fuck off."
Suzy disappeared screaming knowing that person was her brother, because he looked like Dad, but that their father was in Mexico.
Katie's breasts rested on Mikey's chest as biology took over again his flaccid member started to become hard. Katie started to sense that Mike wasn't finished he was just starting with her. He flipped Katie onto her back.
The woman tried to hold him at bay by kissing him teasing him, pushing him away but they rolled onto the floor. Mike easily pinned Katie's hands above her head as he started on her a second time. This time her body was in time with his her d cup breasts bounced and quivered as he pinned her to the floor.
"uh...uh...uh..." Katie sounded like a broken record.
Mike came for the second time in his life but he too was drained. He rolled off of Katie and went to sleep.
