"Whoa", said Matt, in that deep voice Ty wasn't used to hearing.
"Are you alright?", asked Ty.
"Yeah, yeah, I'm fine", whispered Matt back.
Ty looked down at Matt's crotch and sees that Matt's jeans are bulging slightly.
"Aah", whispers Matt.
Matt feels a tightening in his underwear, that feels weird.
Ty looks down and see the bulge becoming bigger and bigger, it must be nearly 8 inches by now.
"Wait, I didn't say when he should stop growing, did I?" Ty thinks to himself. Ty decides to let Matt get a LOT bigger!
Ty glances over again and sees that Matt's pants are already almost at their limit, barely containing Matt's manhood.
It must be at least a foot long! Ty thought, and sure enough, Matt's pants looked very stretched over what looked like a cucumber in Matt's pants. Ty wished that Matt was wearing compression shorts instead.
Ty looked down. HOLY CRAP! Matt's shorts were too close to breaking. It looked like two cucumbers were shoved down there, along with two melons. Matt looked very uncomfortable in his shorts.
Ty wished the growth would stop, and it did.
