Buckets

If your mind wasn't completely focused on fucking this hot gym girl you might have felt a strange weight on your thighs. You might have noticed that under your new massive cock, your balls had been getting bigger and bigger.

But as you give a deep, reverberating groan, Sophia looked down and noticed.

The skin was stretched taught over two testes the size of small melons. Veins visible and obvious with audible churning sounds.

Sophia could also see the obvious shape of your cock between her modest breasts poking through her stomach, under her belly button and she watched with horror and arousal as the monstrous balls contracted.

A moment later you see through a haze of pleasure as the slither of cock you could see visibly expanded. Huge amounts of thick cum being pumped through it.

Sophia was shocked and looked down in amazement as her tight stomach was slowly inflated by the sheer volume. The sound of it rushing into her audible to you both even over your groans.

Her tight pussy grips your stupidly thick cock and not even a single drop spills back out as the pressure inside her increases but your hold of her prevents a single inch from being given.

"what. The. Fuck." she gasped as the flood slowed and your tight grip on her waist relaxed enough for her feet to touch the floor.
