She peered through the doorway to see her step-dad undressing. He had just come home from the gym after a long day at work. She could smell him, he smelled warm and welcoming. He was a decently sized guy. He had broad shoulders, abs and a nice jawline with a touch of stubble. She continued to watch through the crack in the door as he peeled off his clothes, tossing them into the laundry pile. He finally took off his underwear. His cock was perfect for her. He had trimmed his pubes and it hung nicely as he walked to the shower, no idea his young step-daughter was watching him closely. The room was steamy from the hot shower. She knew her mom wouldn’t be home for a while. She watched as he scrubbed his body and slipped a hand down her pants, past her lace panties and to her perfect pussy. She was already wet from seeing her step dad undress. She couldn’t resist and began to rub her clit softly, letting out only the tiniest of moans. The man turned his head but didn’t see her, he continued to wash himself. She decided that enough was enough and took off her own clothes. She waited till his back was turned and snuck into the bathroom. She slipped the door to the shower open and got in with him. He appeared startled at first but relaxed once she grabbed and fondled his balls. He moved his hands across her breast, massaging them. He picked her up and began to kiss her. He pushed her back against the cold shower wall making a shiver go down her spine. It had been long enough and the girl spoke a few words “I want you to fuck me”. It all it took and he slowly slid his hard cock into her tight, wet pussy. She moaned and cling to him more. He moved slowly at first, slowly gaining speed with each thrust. The girl started to moan and moan. Eventually she could t take it anymore and came all over his hard cock.
