They all service Rob orally

"Oh my God, it's so much bigger than John's." Christy says with her eyes wide open.

"Suck his cock, Christy!" Rachel tells her.

"Do it!" Jennifer says.

"Girl, you need a real dick, not the tiny little peepee inside John's pants!" Mackenzie chimes in, to which the girls all laugh.

As if swayed by their comments and Rob's size, she started to pleasure him and all the other girls follow.

Christy sucked on the tip of Rob's penis while Jennifer's tongue went up and down his long and meaty shaft. Mackenzie and May worshipped his sweaty, smelly balls while Rachel stood up to stick her tongue inside his mouth. They all love his taste, your sweet girlfriend included. You can tell because they compliment Rob as they carry out their lust.

"Oh Rob~, your balls are so BIG!" Mackenzie said as she sucks on his nuts.

"And so tasty too!" May adds with glee.

"I could worship this HORSE COCK all day!" Jennifer chimes in.

"I'm never sucking John's tiny dick again!" Christy exclaims.

Soon, 4 of the girls start alternate between his cock and his other manly assets.

You can see Mackenzie and May move from his scrotum to his arms. They suck on his biceps with loving adoration. Rachel starts to lick the big pecs on his chest while Jennifer puts her tongue on his six pack abs.

Interestingly enough, your girlfriend doesn't follow, fixated on his dick and its intimidating size. It gets to the point that the other girls stop going for his cock, cheering Christy on as she services his pole.

"Go, Christy, **** on that big dick!" Mackenzie calls out.

"Suck him dry, Christy!" May yells

"Yeah! Make that dick CUM!" Rachel adds.

As Christy, singlehandedly, worships Rob's cock, stroking it with both hands, painting it with saliva and taking it down her throat, you wonder if he will cum from such impassioned oral sex.
