As her hands close over my shaft I feel a reflexive, involuntary, uncontrolled spasm that causes my member to twitch in her grip.  Then as she positions the head against the mouth of her vagina the welcoming heat and moisture seems to pour over it.  I feel her slowly opening, spreading, enveloping me, as the walls of her vagina grip, and enclose me as my length is slowly absorbed into her.<br/><br/>When her hips settle on mine, all feeling and concentration is on that one area.  I am barely conscious of  any other stimulation save that overwhelming clutch of her tight, hot, wet vagina grasping my shaft.
