You put your arms around Lucy's shoulders so she could get a better grip on you.
"Jeez, you're sweaty. How about we go take a shower?" Lucy said.
You didn't answer but she knew you didn't mind. Lucy carried you like a baby to the shower room in the basement. It was a large room, large enough for the whole family to use if they wanted, with three showerheads. The house's previous owner used the basement as a home gym and wanted a gym-style sower room.
Lucy set you down, and you quickly peeled off your underwear. Lucy turned on some warm water, and took off her own clothes, revealing her toned, athletic body. The warm water felt good on your body, very soothing and relaxing. Lucy was already soaping herself up and washing her hair. Seeing her like that, naked and soapy... you couldn't control it, your penis hardened. Lucy took noticed and laughed.
"Aw, is 'Little Shrimpy' excited again?" Lucy said.
You blushed.
"L... Lucy! I'm sorry, I..." You stammered.
Lucy put her wet soapy hand on your shoulder.
"It's all right, Shrimpy. I'm just too sexy for you, aren't I? You're so lucky, Shrimpy, lucky to have a hot sister like me!" Lucy said with a devious smile.
She moved her and applied some soap to your balls. You moaned with pleasure.
"...Lucky enough to have a hot sister that does stuff like this!" Lucy said.
She scrubbed your balls a little more before abruptly shoving you to the ground.
"Whoah! Hey!" You shouted.
Lucy knelt down beside you and locked your body between her strong, powerful thighs.
"What are you doing, Lucy?" You said.
She giggled.
"I'm gonna wash you!" Lucy said.
Lucy took some shampoo and scrubbed it in your hair. She took some soap and slathered it all over your naked body. You didn't like being held down like this, so you squirmed and struggled, but Lucy held you tight.
"Hey, you're wiggling too much! You aren't making this easy!" Lucy said.
"I... I can wash myself you know!" You said.
"Aw, but I wanted to wash you." Lucy said.
It was clear she was getting some kind of a kick out of this.
Still holding you tight between her legs, Lucy slowly pushed you beneath the shower head. Your butt was rubbing right against her pussy now. It felt weir to you, but Lucy was loving it. She held you beneath the warm water and washed all the soap off of you.
"There you go, all clean!" Lucy said.
She released you and got to finishing up cleaning herself. You left the shower to grab a towel and dry off. You wrapped the towel around your waist, planning on getting a fresh pair of tightie-whities when you got upstairs back your room. Just then, Lucy finished up and started drying off too.
What does Lucy want to do with you next?
