The change was a surprise as was the kiss. Mark was given no opportunity to kiss her back before Claire was nipping his bottom lip. He had barely had the chance to try and move his tongue to play with her own as he felt the way the tip of his cock now hit at a different angle. The change slowed down the rise as the sensation was different and would ensure that he would be able to keep this up for longer than he had anticipated. Mark found her nipple at his mouth, ready and waiting for his lips, teeth, and tongue to show them no mercy.<br/><br/>His tongue lashed out and at first he gently flicked the tip of her nipple as a quick introductory tease. He was all about giving her pleasure, mainly because the more he did for her the more she appeared to do for him, so it was a win-win situation as opposed to the lose-lose situation they had earlier in the day. The nice gentle teasing soon died with one tug from his front teeth. Mark made sure not to bit too hard to draw blood, but she would definitely notice it, and he pulled the bit into a suck and alternated between biting and sucking while throwing in the occasional flick of the tongue to give her nipple a rest. His head was unable to move much so he would be reliant upon her for access to the other breast, but he figured she would initiate that when she was good and ready, until then he continued to give attention while she fucked him silly.
