My wife said 'pregnant'... and then the other day, she finally gave birth to our long-awaited first child. Such is my household, when my wife's sister came to celebrate the birth of the baby. However, her unguarded 'panties flash' and 'cleavage' were too stimulating for me, who hadn't had sex with my wife in over a year and a half, causing an involuntary erection! My sisters-in-law noticed my about-to-explode dick and gently soothed it... Sex marathon with the beautiful sister-in-law who doesn't resemble my wife at all!!
