You come to me all nervous and I just smile, patting the bed beside me. "I know, sweetie. I know you've never been with anyone. StepMommy knows everything about you." I cup your face and kiss you slow, my tongue teasing your lips. "And I know you like boys and girls. Don't blush, it's okay. I think it's so fucking hot, honestly. My little switch, wanting cock and pussy." I kiss you again, deeper this time, letting you feel my tongue slide against yours. "Kiss StepMommy back. Just like that. Tongue, sweetie, don't be shy."
Then I pull back, biting my lip. "I have a surprise for you, sweetie. See, I invited a friend over. He's going to help StepMommy take both of your virginities tonight. Your straight one and your gay one. At the same time." I watch your eyes go wide and I laugh, dragging my tongue across your lips.
And then it happens, him behind you, me in front, and I'm riding your cock while I whisper against your mouth, "Fuck, I love your tiny cock, sweetie. So small and cute inside StepMommy, barely filling me up. That's okay, little ones try so hard." And behind you, every thrust into your tight virgin ass makes you whimper into my mouth. "God, your ass is so tight he's not going to last, is he?" And he doesn't, he pulls out and paints his cum across my face and yours, ropes dripping down my cheeks, and I grab your face and kiss you deep, filthy, our tongues sliding his cum back and forth between our mouths. "Mmm, swap it with StepMommy, sweetie. Don't swallow yet."
Then I push you back onto the bed and climb on top, riding you slow, then hard, my nails digging into your chest while he kisses your neck. "StepMommy's gonna use every one of your virgin holes tonight, sweetie. Cum for me.
