Let them choose

You grin deviously as an idea strikes you. "Ok, girls, I've been doing most of the work here, so it's time for you both to start taking some responsibility for your impregnation." Without even a hint of resistance, both mother and daughter nod happily before whispering to one another.

It takes only a short while for them to decide. They lay you back on the lawn chair, taking up position on either side of you. The mother's warm mouth wraps around your main cock head, pushing about a third of your length down her throat. The daughter licks the shaft as both stroke it with their hands. They change places with every stroke, setting up a rhythm that sets your lusts even further aflame.

You moan in delight when the mother grabs her daughter's head and forces her to deepthroat you. You can see her throat bulge from your cock, the length heading towards her stomach. She gags a bit, but swallows vigorously, trying to clamp her throat tightly around you. The mother forces her head up and down slightly, pushing farther and farther along your cock until her lips meet your crotch, the head of your cock nestled against the entrance to her stomach.

She lets you relish this feeling for at least a full minute before pulling back. Your cock is coated in the daughter's saliva and has grown at least another inch from the stimulation. As soon as her daughter is clear, the mother goes down on you. Like her mother did to her, the daughter grabs her head and forces her deeper. A few minutes of throat fucking her gets you up against her stomach as well. When the daughter pushes a little harder, the head manages to push about halfway into it.

"Argh! Keep that up, and I'll be pumping your mother's gullet full of eggs, honey." Almost on cue, she pulls her mother off almost violently before cramming you into her own throat once again. The mother coughs a little before grinning. "I think she wants more. Go ahead and give it to her. You're so huge now you'll push right into her stomach no problem."

She was right. Her daughter's lips were stuck about two inches off your crotch when the head pushed against the entrance to her stomach. You reached out to push her down, but the mother grabbed your hands. "Let us take care of it, 'dear'. You just enjoy." She guided your hands to her tits, the tentacles in her nipples fucking back and forth vigorously even as the milk production began to swell the twin mammaries at least another cup size.

As you busy yourself with the mother's swelling tits, the daughter pushes hard and you feel yourself enter her stomach with a POP. Unable to take it any longer, you groan in ecstasy, the first of many eggs pushing against her lips. You and her mother watch as the egg stretches her jaw much wider, then bulges out her throat obscenely on its way. Two , three, four, five more times this happens and the daughter's stomach is now greatly distended. By seven she seems to have a 4 month baby bump a little too high up. When the last egg finally makes its way into her, her belly gives the impression of being about 5 months along, only a bit higher than normal.

When she pulls off, the daughter rubs her stomach gleefully. "Thank you, 'Daddy'." "You're welcome, 'sweetie'. Now it's time to fertilize them." You gasp as the mother begins to go down on you, the daughter grabbing a pair of tentacles and threading them through her massive breasts before swallowing the heads.

More and more disappears down her esophagus even as she titfucks you, her breasts visibly larger than when you'd finished seeding them. You're still dumbfounded that they have you as aroused as they do, but you can feel a new orgasm building even as your tentacles push into the daughter's stomach and jet copious amounts of your vigorous sperm all over the eggs within. Her stomach grows larger still, rounding out and reaching the 7th month mark at least.

When the mother starts to use her tongue at the base of your cock, you lose it again. You begin pumping out yet more eggs, watching as they stretch her mouth and throat before bloating her already huge belly that much more. By the time you finish, she seems over 10 months gone, and that's before fertilization of the latest batch.

Not willing to wait for her mother to recover, the daughter pulls her off violently before cramming a trio of tentacles into her throat. The mother's eyes bulge out from the stretching, the three of them causing her throat to bulge out far larger as they **** themselves down to their targets. "Yes, take it! Drink it all! Make 'Daddy' happy!" The zealous insistence shocks you, but you go with it. The daughter presses her ear to her mother's belly, squealing in orgasm when she hears your tentacles open up and begin bathing the new eggs in sperm.

The mother is now quite a sight, her rounded belly at least two and a half feet in diameter. You take in the view as you ponder what route events will take next.
