shrugs and goes back to railing the squirrel, cock growing inside of him, bulging through his chest, making sure to massage his heart with the massive batcock 

Balros & Echoen
The squirrel is tight and impossibly deep, yet you still manage to grow so huge that you're filling and stretching and bulging him out, can feel his heart thumping hard againt your shaft. Your balls begin to throb and beat with the same intensity, bloating with ultrapotent seed. Seed so fucking virile that your womb violently inflates against the squirrel's back and your tits fatten against his head. Wings erupt from your back.

groans loudly, holding the squirrel against his increasingly growing bust and belly, his cock at least 3 times bigger than the squirrel, stretching him out more while he greatly enjoyed the feeling of the squirrel's quickening heart rate against his heavily beating shaft, those thick nipples on those massive breasts quickly turn into massive beating cocks as well, each throb causing the battits to bounce intensely,  balls just getting bigger and bigger until shi's just sitting on them comfortably, precum shooting into the squirrel's belly so intensely that you'd think shi was already cumming

Balros & Echoen
Every throb of your huge cock within him feels like an explosive orgasm in and of itself, each pulse and pump simultaneously with a surge or growth inside the heartpumping squirrel. Fat balls flop forth from your nipples to fuel your nipplecocks, ivory gouts of heavy batty-fieron cum pumping forth with high pressure. Your tits ache wonderfully full and plush, swelling and churning larger and fuller of milk-cum. When you sit on your balls, you're also sitting on your heavily engorged pussymound, nestled between your huge nuts and being kneaded, squished, by their pumping growth. Even your prostate bloats and mutates, plunging you into self-induced throbbing buttgasms; your asscheeks swell round and bountiful.

holds tightly onto the squirrel screetching out in lust as his precum thickens and gushes with each audible heartbeat from the bat's body causing the squirrel's belly to bloat out quickly with all that bat cum.  Soon shi's gushing milkcum from her nipple cocks and hir nose grows out, that too becoming phallic and gushing out highly contagious snoutcum into the squirrel's fur, quickly making his nose grow and throb.  The screetching earlier summons more massive Fiebats into existence which proceed to rub over the squirrel's massive gut and nose, while one easily takes his growing squirrel cock into its massive beating pussy.  other fiebats just take the original Fiebat, one for the massive pussy and another for hir ass.  two more take the nipple cocks into their massive pusses as well, soon both the bat and the squirrel are being taken by every which way
