When used properly.

“You going to fuck my tits or what?” You demand. Upon not getting a quick response, you carefully pull yourself up from a sitting position. You need to make sure your balance is there but as you suspected, you are extremely front-heavy now. You fall onto your belly and breasts. As luck would have it, your breasts fell forward ahead of you and your nips are right at Jay’s waist’s height.

“If I do, you might end up face down for a while, baby,” Jay giggles at your situation.

“Oof, I hoped I was stronger with how big I am down there,” you admit.

“You are a big girl, but so are we, baby! We don’t want you to be immobile! I mean, you move so sexy with your curves...even when falling on your face!”

“You may as well just do it, Jay. I’m stuck already,” you explain. “Impregnate me, please. Knock up my fat titties!”

“How can I say no to that?!?” She asks as she pushes her rock-hard dicks at your nipples.

You didn’t realize how ready you were. Your nipples stretch around her cocks with ease. Your head rests in your cleavage for a close view of her cocks slipping into you. Jay sighs as she fully buries her rods inside you. She then retreats slightly and then pushes her hips forward. Your breasts ripple as the smack of her collision is followed by another. Her tempo has you transfixed as the jiggle of your expansive tits soon translates to a rocking of your bed.

“Here it comes,” you correctly guess once you see her balls twitch and feel her cocks swell as her tubes begin to gape.

“I’m so fertile right now, your fat tits don’t stand a chance, baby!”

It’s different feeling a high volume of liquid pumped into your nipples instead of your biggest asset. You tingle as the cum permeates your tissue, fertilizing whatever grew there over the past few days. You know for sure your breasts are impregnated. You are going to be bringing something (two somethings) to term.

“Am I still going to lactate?” you ask.

“Of course, baby,” Jay says as she pulls out. “You feel it already?”

“My boobs tingle and it feels almost itchy,” you reply.

“Mmm you sure are. Don’t be surprised if you are dripping soon!”

“I can’t wait! I’m going to be stuck for a while though...”
