Pound her Missionary Style

You smile and push her to the ground.
Time to fuck this bitch.
You're already half naked since you was masturbating, so she quickly jumps on top of you.

When you insert your dick, you feel yourself pulse inside her and you know that you are very excited and won't last long, not with how close you went when masturbating, but as you look at her face you see her biting her own lips and feel how wet she is, and you know that she too is very excited. Both will cum soon.

You are half-wrong about that

Annamae lock her legs around your hips and pull you closer and deeper, and you realize that you're too excited to hold on for a reasonable time, even more so when she starts to use all of her tricks, kissing you and shaking and moving her hips in interesting ways as she keep you close to her...

You try to move on the offense, tease her breasts, control her hips, but it's too much. She locks you in a long, deep, kiss and doesn't let you go, her legs trapping you. She will make you dry as she did to her own brother... this excites you so much you lose control of yourself, throbbing inside her. You shiver and start to cum, too horny to care.

Moments later she screams, quivers, and cums as well.

When is over you kiss her gently and smile at her. She fucks like a wild thing and is a hell of a woman to handle both her own brother and you in the same night like that. You liked. You liked a lot. You all rest for a few seconds, then she starts to put her own clothes back.

Her brother gets closer than you both and all of you start to talk. They want you to promise to keep a secret about the whole **** thing, which you easily agree. There is no reason to refuse. Annamae then makes a joke about how she totally owned you and you tease her nipples, still sensitive, while you two cuddle together.

Clarence join and there's a bit of banter after that about who fucks better than who, with several names being throw around, including Calvin's - to your surprise. It's obvious that their family is very weird, but you find that you couldn't care less.

You all talk a little more, about they having an affair and about sex in general, but the duo is very aware that their parents will look for them if they disappear for too long, so soon enough you all must come back to the house.

You return to your room to sleep, happy and satisfied, but also surprised with the whole situation.
