As I left, she said, "Make sure to meet my roommate Mara [changed], she's the hostess upstairs."She had occasionally been texting, and when I met Mara... a few minutes later it was was beautiful. Closer to my age, probably about 28, with light brown skin, curly brown hair with light blonde highlights and a small, slight build with small breasts and narrow hips. But beautiful thick lips and a statuesque nose. Her eyes were blue, but I suspect they were contacts. I found out later her dad was black. This time however, I was the designated driver, allowing Laurie, Kay and Suzy to have a little fun.Some of the items up for bid included artwork, tickets to sporting events, golf passes, vacation getaways, and several delicious looking cakes. Our table went together and won a chocolate caramel cake with a bid of $100. It was nice to donate some money and indulge in something sweet and delicious at the same time. The wine was flowing and everyone was giggling and enjoying our treat, but I had to. I couldnt believe what I had heard. I heard my dad trudge up the stairs to the 3rd floor and heard my mom stop at the second to go change. I waited about five more minutes and heard my mom quietly walk up to the third floor and decided to tip toe after her. I neeled near the top of the stairs and listened. No one had bothered to shut their door since the twin girls were at a family friends house in Maui for the night. I peared in. My mom Kelly was wearing the same sexy sundress she had worn to. My gaze met hers and lingered for about a second then I actually realised she had just caught me admiring her gorgeous body. She flashed a smile and gave me a wink. I leaned my seat back and sat there in embarrassment as she entered the vending area. She slipped in some coins and something dropped. As she bent over to reach into the slot to grab her item, she gave me a good view of her pink panties riding up in between her plump pussy lips. I immediately felt a trickle between my legs and I bit.
