Bob.

"I want to try Bob first," Elizabeth replied meekly, glancing over the massive rubber cock in Talia's small hand.

Amy flicked on Bob and it hummed while it vibrated in her hands. She leaned over my wife's thigh and gently stuck the longer and thicker "finger" of the vibrator into Elizabeth's pussy while the "thumb" rubbed against her sensitive clit.

"OOOOOOooooh..." Elizabeth gasped, trying to close her thighs together but was stopped by the girls, who kept them spread open for my benefit. She bit her hand to silence herself or risk waking up Adam and possibly the neighbors.

My cock got harder as I jerked off to my wife cumming from the vibrations of Amy's sex toy.

"Are you to meet Vlad now?" Talia asked with a mischievous grin as she held up her big dildo.
