I wish the two dildos on the strap on would become two butt plugs, Ty thought. He chuckled when he realized that he actually forgot the names of the father and the oldest son.
The moment Susie took off the strap-on, it began to shift in her hands. The former father dildo separated from the inside of the underwear and fell onto the carpet, shifting into the shape of a round-tipped cone with a widened flat base. Meanwhile, the latex underwear that used to be Alex shrank and absorbed into his tongue-turned dildo, till the dildo was all that’s left. It too molded into a similar shape as his father.
Susie picked up both of the new butt plugs, and threw one for Helen to catch. The two young women giggled as they crouched down in front of each other, and placed each of the butt plugs right under their butts while bringing one end of the purple dildo right in front of their pussies.
With a lick of their lips, the two pushed down. They cringed as the plugs popped into their anuses, and stayed stuck inside with their flattened base pressing between their butt-cheeks. Susie and Helen laughed as they took in the pressure of the plugs inside of them, as they slid their rears a little around their spot on the carpet. After letting the plugs settle inside themselves, Helen and Susie held the tips of the purple dildo against their vaginas.
“Let’s do it,” Helen quipped. And with a grin from Susie, the two women thrusted forward, shoving Billy and Katie’s former rears through their slits. Yet another chorus of moaning filled the bedroom as the women pushed their hips in and out, and forced the dildo-heads further into their bodies. They pushed against the women's fleshy vaginal walls, which also pushed against the two plugs inside the women’s asses.
Billy and Katie were feeling the same ecstasy that their father and their eldest brother were immersed in right now. In their reduced form, they thought little about their former identities as normal, separate human kids, and now acted more like a single toy longing to be touched and played with.
As their squeals continued to ring in the women's heads, Helen and Susie bent their heads over and shared a french kiss. With their tongues invading each other's mouths, all three of each women's main orifices were filled.
Ty continued watching from the sidelines as the women continued to thrust their bodies. He was preparing one more depraved transformation.
