She continued...

"Mmmmm," she hummed around you. "It's really different."

She then started bobbing back and forth slowly, moving slightly down your length with each movement. She certainly didn't get all the way down, but she made it maybe halfway before stopping and holding still, feeling you inside her mouth.

You watched as she began moving back and forth again, keeping her hand fixed around the base of you cock. You could feel her sliding her tongue around experimentally while she sucked on you. You could hear Terry shifting behind you on the bed while she watched.

Marcia pulled her mouth off you and breathed heavily, her eyes glazed with lust. She looked up at you, still pumping your cock with her hand. "I think you need to fuck me now, Y/N. Where should we do it?"

You looked over at Terry, waiting for her input. She fidgeted for a moment and took a deep breath. "Of course, on our bed."

Marcia nodded and took you by the hand, leading you to the bed.

As soon as both of you sat on the bed, Marcia's hand was back on your cock, stroking steadily as if to make sure your erection went nowhere.

"Y/N, since Marcia wants me to feel like a part of this whole experience, I'm going to sit back on the bed," Terry said as she scooted a little to make room for us. "Then Marcia is going to lie back on me and I'll hold her while you kneel between her legs. From there, you can fuck her and cum in her.

Terry went into position. Marcia crawled towards her girlfriend on all fours, looking back at you and smiling before wiggling her butt. You could see her wet pussy in the dim light before she turned over and laid back on my Terry .They looked at one another and kissed lovingly while Marcia spread her legs wide for you. She then looked at you, smiling. "Give me that dick, big boy..."

You moved in and knelt in front of her, sidling forward. You took hold of Marcia's hips and positioned your tip near her entrance. Your pointed the tip near her entrance even more, making her shiver and giggle. Then you slid it up and down her lips, parting them slightly, before pushing forward gently until the tip was about to enter her.

"May I?" You asked, something you did with every girl. They both smiled and nodded. You eased yout hips forward and slid your cock gently inside her. Marcia stiffened and took a deep breath. You are halfway inside her now and paused, gauging her reaction.

"Gnnnn, you can feel it throb in you..." she breathed, looking at you with glassy eyes. Her hands reached back and held Terry's shoulders. Terry was staring rapt at her girlfriend's pussy, with your cock sliding inside her.

You pushed forward again and Marcia groaned flexing her fingers and squirming, her eyes closed. Her curly brown hair spread out over Terry's chest.

"Thank you, Y/N," murmured Terry. "Thank you so much for doing this. Give me and my girlfriend baby..."

Her pussy was certainly wet enough and you began to move back and forth with your hips, pushing your cock a little further into her each time, but taking it slow. You didn't want to hurt her. If Marcia, didn't get pregnant this time, it wouldn't do to have her dreading another session. You maintained a nice, slow rhythm, allowing her to adjust.

"That feels... really good..." Marcia breathed, looking at me.

"Bettern'n a dildo..."

She turned her head and pressed her lips to my Terry's, the two of them kissing hungrily. You tried not to watch, but it wasbreally turning me on making out. But you are here to give them a baby and that's your priority.

"Nnnnn, go faster, Y/N..." Marcia moaned while my Terry kissed her. Their tongues pull at each other and Terry squeezed Marcia's breasts and pinched her nipples. Marcia groaned and her hands came down and stroked your forearms. She was not only caressing you, but feeling your muscles and it occurred to you that she might like your strength.

You not only began moving back and forth more quickly but strongly, pumping into her and she gasped loudly, breaking the kiss and looking at you with wide eyes. "Oh my God, yesssss," she panted. "Mmmmm, more of that!"

"Try squeezing your pussy around me," You said as you held onto her. "You'll like it."

She tried to squeeze, letting out little gasps as did so. You could feel her tighten around your cock. You moved closer and she keened as you pushed deeper inside her. One of her hands snaked down and began massaging her clit, stopping to feel the top of your shaft as it slid wetly in and out of her. She kept squeezing, trying to match your rhythm. You glanced up and looked at Terry- her face was flushed, but she was watching her girlfriend intently, lost in the sight of her.

"Unh, oh God," Marcia grunted, her body starting to shake. "Oh, Jesus, I'm gonna... fuck!"

Terry jammed her mouth against Marcia's, kissing her fiercely as her girlfriend contorted and writhed, screaming as she came. You held her hips tight, feeling her pussy clamp down around you, fluttering through orgasm. You allowed yourself to pass over the threshold of no return, the tingling heat spreading through you.

"Gonna cum!" You said in a strained voice, pushing as far in as you could and remain kneeling. Marcia nodded her head eagerly even as she kissed Terry, moaning her assent. You sighed and jammed your hips forward, burying yourself in her. Marcia went rigid and screamed again into Connie's mouth. Your pearly cum inundated her pussy, with your body heaving against her.

You relaxed, sagging in on yourself, kneeling between Marcia's legs and your cock still throbbing inside her. Marcia and Terry were still kissing, but it lacked the urgent nature of the earlier kiss while she climaxed. It was gentle and loving now, a shared moment of contentment. You watched them quietly, smiling at a job well-done.

Marcia finally ended the kiss and smiled at you dreamily. "Gotta admit, that was better than I would have guessed it could be. And damn, son, you cum a lot. I'll be sloshing for days when I walk."

"You were warned," I chuckled, gently and slowly pulling your cock out of her pussy.

Weeks later, Marcia got pregnant and thanked you several times for the job well done. Even Terry offered you a chance to live with them while Marcia goes through her pregnancy, but you declined.
