What had her so worked up?  Gosh there was so much, more than she could really think about as she wrapped her lips around the shaft and took Mark's cock into her mouth. The cheating, there was something hot about the sneaky hiding infidelity. The way he objectified her, even though she was overweight and well into her 30's. Chris had barely ever done that, and by the time she started having his children he almost treated her more like a mother than a wife or lover. And there were baser instincts- Mark was big and strong and young, and had a big cock, much larger than her husband. He could finish and get right back up, it was like having a sex toy that was a real man.<br/><br/>She gasped with her mouthful, slobbering a little and stroking it in as he grabbed her hair then pulled her heavy tits free from her shirt and bra, letting them hang out of the top. Trish felt like a sex toy herself, but it made her feel sexy, and she redoubled her efforts.  They could go to the bedroom after this, she knew he would be hard again before they made it to the top of the stairs, and she started bobbing and throating with little gags, using her spit to keep her hand slippery and sliding as she gripped tight. Trying hard to make him cum in her mouth.
