The young woman grimaced a bit as her stiffeness rubbed uncomftorably against the cold rock when she shifted.  She found her own breasts leaking with increasingly more milk as her arrousal started to climb,  and slickness was begining to run slowly down her own thighs.  She continued to drink, more and more of that warm creamy fluid that was dripping down her throat, by now though it was also running down the various scant curves of her body,  as well as splashing against her face.  Still the other hand worked,  tugging and squeezing on the thick portrusion trying to coax more and more cream fourth until the woman had her relief.  The soft touch of at the back of her hand caused her to moan against the woman's breast as unwittingly she began to slowly grind her cock against the rough stone.
