Absolutely. And Kristen has a plan
From Torg Adventure
It didn't take long for you to start getting hard again - partly because you now had an unobstructed view of three hot women bringing two of them closer to orgasm, and partly because you slid up behind Kristen's inviting parted thighs and started to rub yourself against her. As Kristen started to grind back against you, she took her hand from Meg's cunt and leaned up to her ear to whisper something to her. You couldn't hear what was said, but the raven-haired girl's sudden enthusiastic moan and grip on Doe's ass left you with good reason to guess that Kristen had filled her in on the plan to impregnate a third woman - and that Meg loved the idea.
Meg started whispering loudly as Kristen switched to move her ear toward Doe's, and her lustful cries of "Yes! Oh yes! Do it! Please!" made your cock twitch. At the same time, Doe groaned and nodded her head, then lifted it to look over her shoulder at Meg, then to the blonde, and then turned back to you.
"You really get off that much on it?"
Your face flushed and your lips parted to answer, but Kristen cut you off with a "Yes! We fucking love it! Please do it for us!"
Doe turned three shades of red, then suddenly waved you over. Softly, she said "Alright.. Come stick it in me, then."
Your mouth gaped and you weren't sure if your face was white or red. Kristen revealed her deception by grabbing your cock and leading it to Doe's face with one hand while grabbing a fistful of her hair with the other. Her eyes burned into yours as she said "This is going to be so hot!"
With a sudden shove, your step-sister's face was pushed onto your half-hard cock. Kristen held the base of it, and Doe began to suck you as hard as she could. Meg's head dropped from the pussy above her and called out, "Oohh yeaah! You're going to give it to her, aren't you?!"
Kristen nodded and moaned. "Yeeessss. He's going to give it to her so hard."
You'd never seen her look so turned on. She started to force your sister's head back and forth.
"He's going to put it deep inside of her belly," Meg moaned, now rubbing her pussy and sliding a finger into herself. Doe was startled by the words, and you were sure that both of you had wondered whether Meg meant you'd fill your sister's pussy or her throat. When she recovered, Doe worked your cock with more hunger.
"That's right," Kristen cooed. "We're going to make her take it."
The double meanings were causing you to get harder faster than you thought possible, and as Kristen noticed, she pulled Doe's head back.
"Do you want your brother's cock?" It sounded so innocent and teasing as she held your sister's lips back from the tip.
"Yes!" she breathed.
"Yes, she does!" Meg loudly whispered.
"Do you want it deep?" Kristen continued. Doe hesitated for a moment and looked at the length of your cock, then lifted her eyes to your reddened face.
"Yes," she said again, a little more quietly and less sure of herself - though a quiver ran down her body and her fingers touched her pussy.
Kristen leaned in close and started to press Doe's head forward, letting her lips have the tip of your now rock solid cock.
"Ohh fuck! This is so hot! She's getting off on it!" Meg groaned, panting harder.
"Do you want to feel him cumming for you? Inside of you?" Kristen asked insistently.
Your sister's eyes fell into a lustful haze as she responded with a purring "Yyeesss."
Where do you give it to her?
