The Babysitter and the Sisterly Trio/ChapterVIII/Bear Evy/Vibe Riley
"What are those for?" Riley asks, confused.
"I'll show you." I tell her. I sit down on the bed next to Riley, and lift her into my lap. I pull her pants down to her thighs, and pick up the vibrators.
"See, these vibrate when you turn them on." I explain to her. "And if you put them in the right place, it'll feel really good!"
I turn on the froggy egg vibrator and move it down to Riley's groin. Finding her little clit, I press the vibrating frog against it. Riley lets out a sound halfway between a moan and a squeak, and cums almost instantly.
"Th-aaattt fffeeelllsss ssssoooo g-ggoooooddd!!!" Riley exclaims with a whoop.
I pick her up again and set down on the bed beside me. Then her guide her hands to hold the vibrator against herself, and tell her to try moving it around a bit to find the places it feels the bed at.
Now it's Tera's turn...
