"I can't wait, but are you not late already for your gym class Ashley?"

I say. Ashley quickly understands what I am trying to do, so looks at the time, shouts "Oh my god, I am so late!" and runs out of the room. She shouts "by mom!" and "nice to meet you Matt" as she opens the front door and then slams it shut.

Millie looks a bit deflated, and says: "I was looking forward to showing you guys my summer gear."

I reply: "I would still love to see it."

Millie stands there, thinks for a while, then says: "Change of plans actually, I am a bit tired so I am going for a nap." She spins around and walks out of the living room, and I am just sitting there a bit confused and not sure what to do. Then Millie shouts as she is walking up the stairs: "You want to join me?"

I get a big smile on my face, so I quickly follow Millie up the stairs into her bed room. As Millie enters her bed room, she pulls her dress over her head, leaving her wearing only a tiny white thong and then she crawls into bed. I quickly slip out of my clothes, make a split second decision to also take of my underwear, and crawl into bed with her.

Millie is under the blanket, so I also go under the blanket and snuggle up next to hear. I lean in for a kiss, and she kisses me back, pulling my head closer to her with her hand on the back of my head.

I run my hand along her body, feeling the outline of her breasts, the side of her stomach, the string of the tiny g-string she is wearing, then her thigh. We kiss some more, and I start touching her big tits, then I run my hand along the other side of her body, but there is something missing, I can't feel her g-string there any longer.

I get a bit confused, so I move my hand along her hip for a while, then Millie opens her eyes and asks: "You did not notice me slipping my panties off?"

I give her a deep kiss, and roll on top of her. Millie opens her legs a bit, and I can feel the wetness of her pussy on the top of my dick. I push very gently, and the top of my dick slides into her. Millie's fingers are grasping my shoulders, I push some more, and my dick disappears completely into Millie's pussy.
