Sophia could not believe the feel of his mouth on her breasts.  She'd had men kiss them before, of course, suck on a nipple, lick.  But despite the fact of how sensitive her breasts were, it usually did nothing for her.  They were clumsy and ridiculous looking.  Something about the way Justin devoured them, though, his mouth moving every time it seemed she couldn't take any more at that spot, varying what he did, but always with such intense passion.  She felt like for the first in forever she was with a man who had as much passion as she did.<br/><br/>And he was relentless.  His cock was grinding against her pubic bone, a delicious motion that could have brought her to orgasm by itself, given long enough.  But now he added his fingers, pressing them through the sheer silk of her panties against her lips.  The cock added the hard grind, the fingers the teasing stroking.  It was all she needed, it was all she could handle.<br/><br/>Justin could feel Sophia jerk in his grasp, pinned against the wall as she was, her arms twisting in his grasp as her body tried to find some way to contort itself, to express its peak.  She grabbed his head in her hands, hard, her nails pressing into his scalp unknowing as she tried with all her strength to hold him, right there on her left breast, his mouth on her nipple.  She was cumming, it was coming, she was trembling and she did not want him to move, not an inch, using every muscle in her body to clamp down on him, hold him still.  For a long agonizing moment nothing moved, not a breath, not a twitch in her, until she feared she would just die, that this slow building peak would never come.  And then it did, and she arched her back and cried out before taking in a long rasping gasp, her panties flooding with her moistness.
