Jenni and Dana's on top

Donna leads both Dylan and Keeani outside while the pair wait inside.

She returns and puts strap on cocks on the two bound women.

The pair are led outside and see what Donna prepared...

This looks fun.

"You're done yet," Donna says, setting up a wired box.
She connects both fake cocks to them.

Now they can hum and zap.

"I suppose you'll need your hands for this," Donna says, rubbing Jenni's tits.

She removes the metal stocks and chains her hands in front of her like Dana.

They move into position.
Dana goes first, with Jenni taking mental notes...

Dana fills up Dylan's pussy.
Jenni gets her own 'cock' inside of Keeani's pussy.

They both start to fuck the pair...

Donna smiles.

She flips the switch and slowly turns up the power.
She wants to ease them into it at first.
