It is enough to get you another hard-on.

You move near Rikku, place a hand on her hip and start caressing her tender skin. It is enough to get you another hard-on. After a few kisses you **** her to turn around. She lie on her belly, her face buries between the pillows, her arms and the legs slightly apart.

You gaze at her for sometime and then place your hand on her back. You slide your finger over her spine, from the nape of her neck down to the beginning of the deep valley that separated the two full mounds of her bottom. You place a hand on each side of her cheeks and open the mounds, exposing her anus. It is a round, protruding, slightly puckered hole covered by dark, almost purple skin.

Between her anus and her pussy is darker skin covered by light and short fluffy hair. You can't stand anymore and dive your face in that adorable valley, your tongue darting to the puckered hole. Rikku’s body shudders fiercely as if she'd has been whipped. You cover her anus with your mouth, sucking it and pushing your tongue in at the same time.

Rikku responds by raising hre ass and forcing it against your face. You suck more strongly and her body stiffens. She is panting loudly as you repeat the caress several times until you are breathless. You break off and she remains with her face buried between her arms. "Put your cock in my ass, John," she pants, "but lubricate it before you do."

Rikku indicates to a tube of Vaseline. You place a big glob of Vaseline on your finger and push it slowly into Rikku's bunghole. Working carefully to stretch her sphincter, you move in slow circular movements, her ass widening more and more as she relaxes her sphincter. You add more Vaseline to keep up a good lubrication. You play with her bottom a long time, loving it, but the pressure in your cock is growing urgent so you lie over her.
