My Mother was shocked when she greeted us on Tuesday, the 26th of November."Are you girls pregnant?" she asked in shock."Oh yes," Margie answered with...a big smile."But how ... when!!?" Mom stammered."The usual way in late August," Katie told her."When are you due?" Mom asked still startled."In late May," Margie told her."And you're this large already?" Mom asked in amazement."Yes, we gained a lot of weight, and started showing very quickly," Katie told her.Needless to say Dad, and later Uncle. She broke the embrace and told me she loved me and missed me so much. She jumped up and said lets go swimming, I told her I had no swim trunks and she said that was ok because she knew before hand and picked me up some along with a couple shirts and some sandals. When I left home I had a backpack with only a few pieces of clothes. She warned me that since I lost so much weight through basic training that she might have picked up a size to big but I should be ok. She then showed me what she got. She says,"I have a suprise for you" and pulls out a strapon. "Yes oh fuck please." She grabs my legs forces them above my head. "You've been a bad bad girl. Fucking my boyfriend. Hun touch your dick again" she puts in deep and I scream "FUCK" and she pounds my little pussy. "Cum baby cum" I sqeel, sqwerm, squeeze my pussy down, and cum. "Now suck all this pussy juice" as I slurp every drop. "Okay, let's take care of you now" as we pull him on the bed.He grabs his girlfriend and throws her down.. Once outside the bathroom window, I stood there not 10 feet away and watched Krista strip out of her clothes. She had nicely shaped tits just barely a “B” cup [baseball sized] with a small mole about 1" from her left areola. Her areolas were the size of quarters and pinkish brown with nipples the size of pencil erasers. While her hair was a blondish color, her public hair was the same color as her mother’s. Mousey brown in color, Krista had a nice full triangular patch pointing to her well.
