Your little sister finishes you off

“Sure,” you say.

She reaches out her hand and grips you. She giggles. “It’s harder than I expected.”

She squeezes you, pumping the blood in your cock and sending pleasure through your body. She sees you twitch in pleasure. “Does that feel good?”

“So good,” you groan.

Your little sister slides her hand up your hard cock. She palms your tip and squeezes. “Oh that’s almost squishy.”

You squirm in pleasure. Fuck. You’re so close to exploding again. Your little sister is too attractive and too curious.

She slips her little hand up and down your cock. She looks up at you, “Is this what you were doing when you were thinking about me?”

She grips you with her other hand. She uses both to stroke your cock. “Were you thinking about your little sister naked in the hot tub? Did my body have you running in the bathroom to do this?”

Fuck. She’s too good at this. You’re so close. You bite your cheek to keep from moaning her name.

“What’s going to happen if I keep doing this? Show me. I want to see.”

You thrust and start fucking your little sister’s stroking hands. She milks you like a cow. Your knees go weak. Your cock throbs. Cum explodes from your cock and splatters the lifted lid of the toilet. You groan and shoot another rope. Two more fall into the toilet.

You have to peel your sister’s hands off your overly sensitive cock. She’s giggling in delight and you collapse to your knees in pleasure.

Holy fuck. A handy from your 18 year old sister. You weren’t expecting that tonight.

Your little sister says, “If you can get it hard again, you know where my room is, I want to learn more.”
