Sex marathon with Saya

"Don't get too cocky now stepson! Just because you have great abs doesn't mean you can keep up with me in bed!!" Saya winks in challenge.

You smirk at your confident and easygoing stepmom: "But you actually want me to keep up with you in bed don't you?"

"Of course! I'm a cool and supportive stepmom! I want you to be the best at everything you do even sex!" Saya says energetically.

"You really are the coolest stepmom ever Saya I mean it!" You touch her perfect C-cup tits and play with them for the first time. They are shapely and perky but still feels soft to touch. You can spend all week playing with her tits and ask nothing more!

Saya caresses your abs lovingly and says: "I'm glad you think I'm cool Takeru-kun because when I married your dad I was scared you'd hate me."

"I don't hate you Saya. You're coolest girl in our class!!" You caress the athletic body of your classmate turned stepmom while she smiles winningly.

You then position your throbbing dick at the opening of her perfect pussy: "I think we did enough warm-up. Let's start the real training!"

Saya grins naughtily: "I thought you'd never ask! I'm ready you can go ahead and jam it in~!!"

"AHH!!!" You and your stepmom moan together as one as your rock hard penis penetrates her pink pussy inch by inch. Its easily the greatest pleasure you've felt in your life and your mind almost goes blank from the sensation!

"Damn you're huge!" Saya shouts while you go all the way into her. She moves her hips and leads you deeper inside refusing to back down from the challenge.

You start thrusting like a machine. Saya moans louder with every thrust. You are both covered in sweat after a while but neither of you want to stop!

Saya wasn't kidding when she compared sex to physical exercise. You pant from how good it feels and hope that you won't disappoint your athletic stepmom by ejaculating too early. "Fuck me harder Takeru!" Saya drops the -kun while begging you to fuck her harder.

"SAYA!" You lose track of time. There's just you and Saya now. Nothing else in the world matters! You pound into her with every shred of strength you have making her gasp from the intensity of your desire! You can feel her pussy contract when she has her first orgasm!

You have a moment of triumph understanding you made Saya cum first! But you're not too far behind in your own orgasm.

Your mind goes fully blank this time from how good it feels! A moment of darkness then you collapse on top of your equally exhausted stepmom.

Saya says dully: "Wow you're really something Takeru. I don't think I can move my legs."

"Me neither" You whisper too tired to speak louder.

"I think we went a little overboard with how hard we fucked" Saya admits. Then she playfully caresses you on the back: "But the second we can move again I want round two!!!"

"You read my mind" You chuckle realizing that this whole week will be a sex marathon with your stepmom! You feel a little scared of dying from exhaustion but if the later rounds feel as good as the first it will be a worthy ****!
