Onyx moaned into her toy's rear as the tip of her cock was suckled on so daintily, her hips involuntarily thrusting a bit and poking the sensitive back of Rose's throat. She redoubled her efforts, sending her tongue thrusting deeper into her tight rear while the hand stroking Rose's hair began to push gently, guiding the FennMink to go deeper and swallow her into her tight throat, wanting to bulge it out with her cock and truly pleasure her Pet who was so sensitive there. At the same time the hand groping Rose's ass slid over and slipped a thick thumb in with her long tongue, letting her continue to stretch the hole while focusing her tongue on teasing her deeper.
