My sister.

"Now you was putting on a good show." Sam said. "If you had something worth showing.".

I start to cover up with my hand and Sam shows me the video on her phone.

"Hands off my property, baby dick or the video goes viral." she said.

Sam locked the phone and put it in her pocket.

"But..." I start to say and Sam cuts me off.

"You are now my C.F.N.M. ****, and will only speak when spoken to." Sam snaps.

"What's that Sam." I say.

"What's that "Mistress. " And it means you are now my naked ****, it stands for Clothed Female Naked Male. Do you understand? Sam says.

"Yes Mistress." I say.

"Good. Now mix me a Mojito and get me some towels." She says. "I am off for a swim."

"Yes Mistress." I say.

So I go and get the towels and put them on the sun lounger and then mix the drink. By the time I am placing the drink on the table she is laid out in the sun wearing a scandalous bikini, she takes a sip and hands me a bottle of tanning oil and lifts her left leg.

"Oil me up ****." she says.

Now I have never oiled up a girl or even touched my sister. now before I got the top off the bottle I was at full mast.

"Perverts that get hard over there sister need punishment." Sam says. "Now cool off and swim some laps while I think.".

I start swimming and keep going until soft.
