So I look in and see it goes right into the guests bathroom. We haver forced hot air and the hole came through the back of that resister and someone h...d painted it black so nobody could see you. I laughed it off as who is going to look at their k**s.almost a year goes by and my wife's younger sister comes to stay. She's 22 5' nothing and pretty as hell. We had three k**s and was nice to have her around as my wife worked nights to help out. Well one night I was finishing putting the k**s to bed. She twitched under me as I took that erect spire and rolled it between my thumb and forefinger. As I felt her body quivering under my tormenting caress, I pressed my rock-hard dick firmly against her, sliding it rapidly back and forth along the full length of that slick sweltering valley."Oh Andy ... wha ... wha ... OHHHHHHHHH GODDDDDDDDD!" she moaned loudly as she started to come. I felt my balls drawing up close to my body as she started to convulse and shake in my grasp. I tweaked her clit. She was shattered. After the emotional energy she had put in to the tour and the big night she had with her friends the night before she could not wait to finish today. It was not going to be a big finish to the day. She just had to tidy up the petting zoo and tend to the elephants, chimps and giraffe next door. Lucy sat and cuddled a baby chimp in the enclosure, she had done all of her duties and had half an hour left until leaving. She stroked the chimps fur and watched the others playing as. I rub your forearms gently…slowly…generating heat between us, and you bend down to kiss me. I love that first kiss, when your lips are still cold and you’re so hungry for me it hurts. Don’t deny it, you… You cradle my head and tilt my chin so when your tongue slides between my lips… it’s like a million little fireworks are going off inside me. So hot and explosive, I know my new panties are already stained. We always skip dinner after that. Even though I’ve kept it warm for you all day between.
