That one summer was finally coming to an end. Mom and I had spent the summer getting to know one another intimately. Making love to a beautiful sexy woman is so special and when that woman happens to be your own mother it takes everything up another level of intensity and excitement. I had learned so much, not only about how one woman wants to be treated and loved but about myself also. I was confident packing to leave for my first job out of college. I knew more about who I was and what I wanted for the life in front of me. One thing I wanted was to make love to my mom more. I just couldn't see not having her.
"Don't forget son, your sister wants to see you before you leave." Mom told me, slipping on that thin worn gown I had come to enjoy so much and walking slowly to my door to go clean up.
"Ok mom." I replied. What on earth could my sister want to tell me, I thought as I went to the bathroom for a shower.
I had barely seen my sister this summer given how involved Mom and I had become and how little Debra seemed to be at home. As I showered I began to picture Debra in my mind, seeing an eighteen year old, athletic girl, 5 ft 3 or 4 inches tall with a decent figure. I was guessing Debra to be about a 34c to 36B bra size, maybe a waist at 23 or 24 inches and a nice shapely ass, She was toned and tanned from all the water skiing she and her friends do every summer. She wasn't a total jock type because at times around the house I remember seeing a young woman in very feminine clothes making a noticeable impression on me. The more I thought about my sister a very familiar feeling began to spread through my crotch. Just picturing my sister in my mind was actually arousing me. Taking a deep breath and slowly releasing it I gradually clamed down enough to finish the shower and change into shorts and a lightweight tee shirt. I had several days before I had to get to my new town for my job so I was still thinking about how many more times Mom and I could get together. Standing in front of my sisters closed bedroom door, I knocked and said, "Hey sis? Mom says you want to tell me something?"
"Come in." I heard Debra say, so I turned the knob and pushed open the door taking several steps into my sisters' room.
Debra was on her bed sitting cross-legged wearing her bikini top and a wrap skirt under which I assumed she was wearing her bikini bottoms. I was pleasantly surprised that Debra had enough fullness in her breast to be wearing the top I now saw her in. Like most girls her age, Debra didn't seem embarrassed about her body or how she showed it off. I quickly noted that in a few years Debra could be rivaling our mother in the looks department.
"Hey sis. What do you need? I'm headed over to a friends house in a minute." I offered to get the conversation going.
"How many more days are you going to be here?" Debra asked looking up at me leaving the magazine she had been looking at in her lap.
"I'll be here five more days before I drive to Clarkson." Answering my sister.
"Good." She said, adding, "I think we need to have a talk about Mom."
Debra just looked straight into my eyes not giving any hint as to what she meant by that statement. I was taken back at first wondering if she knew anything about mom and I? Measuring my response, I kept Debra's eye contact and bravely replied, "What about Mom?"
Debra moved to the edge of her bed never letting her eyes leave mine and stood. Then reaching down to let her wrap skirt loose she dropped it to the floor at her feet. Before me stood my nearly naked sister wearing the briefest thong I could recently remember seeing on any woman. My eyes went straight to her crotch, which made me noticeably inhale as I saw how little coverage Debra had over her pussy. I immediately knew that my sister must be clean-shaven since any pubic hair would be quite noticeable with that thong.
"I'll tell you later big brother." Debra said placing her hands on her hips and slightly pushing her chest out as she added, "What do you think of my new suit?" she said smiling as she turned in place showing me her firm tanned bare ass.
"Great!" I told her starring at an ass I couldn't quite bring myself to believe was my sisters'.
"I wanted a mans opinion before I let Mom see me in this." Debra told me, as she kept moving around letting me get as good a look as I wanted. "You don't think it to, uh, revealing? Do you?" dropping her head just a bit then raising her eyes to look at me sheepishly.
