The little word at the end earned Roslyn's buttocks a loud smack as Sara took her 'revenge' for it, smirking amusedly. Her hand rose and smacked on the other cheek as she tapped the toy's tip against Roslyn's mound, brushing to it a hint as she spoke up. "I think we should get this a bit more slick for that cute backside, we don't want to injure the slutty little butt with a dry insertion now do we?"<br/><br/>Her tone was a bit teasing and friendly, her other hand parting those buttocks a bit better to rub her thumb gently along the pucker's rim, massaging it teasingly. Taking care to not press too hard, she slipped the tip of her thumb up within Roslyn's backside, rubbing the pucker itself with the thumb teasing the gates, her other hand massaging the rubbery toy's tip against her mound.<br/><br/>"Starting to look ready to me. Lovely snug butt, and I guess I should have something slippery for the toy to aid it in its journey inside you dear."
