As you gently probed the swelling orbs in your ballsack, you kept on thinking how good it felt to be this full. The essence you had taken inside had fully become a part of you, leaving a pleasant jiggling tingle below.
You needed more.
Grabbing another Cum Production vial, you unscrewed it and held it up to your cock greedily. The essence inside could sense the presence of a body and oozed itself inside just like the other one, a wet mass squelching and being slurped down toward your balls and prostate. There was a small pinch of pressure as the lump reached the testicles, then relief as it passed inside and melted into you causing it to get bigger.
A shudder confirmed it. You now had the cum production of three grown men, and judging by the pulsating tightness behind your crotch you were starting to see some serious bulging even though right now you could still keep it inside. How much more could your body take?
