Ben Jerks Off

"Man, why do you wanna see me jerk off?" Ben asked defensively, although his cock did start to chub up at the thought of it.

"Ah I get it, you're nervous" Sebastian needled him again, "Don't worry little cousin, I'll help get your little shrimp dick here started"

Unbuckling his own slacks, Sebastian wiggled his ass until they fell to the ground and his own huge cock fell free, slapping audibly against his inner thigh. Smirking to himself, Sebastian pulled Ben forward by his now extremely hard cock until they were side-by-side.

"Ben man, look at the difference! You're as hard as a bone and I'm soft as a noodle, but look!"

Sebastian lined their cocks up side-by-side, holding his soft and floppy cock up against Ben's rock hard erection. Ben flushed red with embarrassment noting that his hard cock was probably 2-3 inches shorter than Sebastian's completely soft cock, and much less thick. Ben was feeling totally humiliated by the sight, but his cock got even harder at the comparison.

"Damn Ben, looks like seeing your shrimp dick up against mine gets you pretty hot" Sebastian chuckled, gathering Ben's now copiously leaking precum and smearing it along their cocks.

"F-fuck you Seb, I-I'm not..." Ben protested, but felt himself squirming under Sebastian's skilled hands.

"Damn man, if I knew you were this hot for my big cock I'd have gone for you first" Sebastian mused, now using his slick hands to jerk both of their cocks at the same time. Sebastian's cock had hardened up to his massive 9 hard inches but he had modified his stroke to focus more on Ben's little dick.

"I, ahh- I'm not" Ben moaned trying to protest but his body betraying him. Ben felt his knees go weak, his abs start to tighten and his short cock had started to shudder.

Ben had always told people he was 5-inches to start, which was already a little below average, but the truth is he was closer to 4. He loved seeing the look of awe and lust on people's faces once his cock had swollen up into his massive size, but the attention from Sebastian was making his cock seem kinda hot when it was small too.

"S-Sebastian, I- I think I'm gonna cum" Ben moaned, now eagerly thrusting his hard, short cock into Sebastian's slick hands and against his own humongous meat.

"Yeah man, fuckin' come for me" Sebastian groaned, feeling his own cock start to tremble and shudder in arousal.

"Maybe we'll practice up a few times when we go to bed and in a few days I can fuck that tight throat of yours while Sue watches and plays with herself"

That thought was all it took for the two of them to start spilling their loads. Ben whimpered and groaned as his cock started to spurt his thick load into the air, splashing a little on his naked torso and arms, and coating Sebastian's stroking hand with the rest of his thick load.

Sebastian's mighty cock shot a matching huge load. After the first few shots went wild, plastering a bit of the walls and the mirror of the changing room he took the squirting cock in hand and directed the rest onto Ben's naked torso. Several squirts later his massive cock ran dry, and Ben's bare torso was plastered with Seb's warm, sticky cum.

"Seb, man-" Ben began to pant, slightly torn between anxious, grossed out and extremely turned on.

Noticing that an errant squirt had splashed Ben in the face, Sebastian smirked and leaned in.

"Sorry man," he offered, extending his tongue to eat the rest of his load off of Ben's upturned face. He scooped it up with his tongue, cleaning the rest off with heavy, sloppy kisses. Before either cousin realized it they had started to exchange sloppy, cum-filled kisses; the kind Ben normally thought of when he busted in Sue's mouth and they made out immediately after.

Realizing what they were doing and how much the shopping trip had taken a distinct trip to gay town, the two boys broke apart quickly.

"Fuck man, we destroyed this place" Sebastian changed topic quickly, surveying the sticky mess they had left the changing room, "grab your shorts and lets get out of here."

Ben agreed and pulled his clothes on without speaking a word about what had happened. That had just gotten out of hand, it had been an accident. It wouldn't happen again, right?
