Have some fun while you experiment some more

You take a minute to think on what to do next. In reflection, your body might be Olympian but your equipment is not. Between your legs is a perfectly average 6-inch shlong, currently at half-mast

“I wish I had a huge, addictive, 12-inch cock that women would find irresistible when they see it.”

Mr. Happy starts to grow, standing at full mast almost immediately; he doesn’t just stop there, however. Your cock swells, that magical tingling sensation running throughout your shaft as it grows longer and thicker. Soon, there's a grin on your face and a foot of meat between your legs.

“I wish Jennie forgot something important in the bathroom and has to try and get it right this second.”

There's a loud knocking at the bathroom door followed by Jennie's voice, “Hey, Meat-Head, are you almost done?”

Meat-head? That's a new one. “Not yet, why?” you reply, turning on the shower with a shit-eating grin across your face.

“I- *Ugh* -I forgot my cell phone in the bathroom. Can you just, like… hand it to me?”

Sure enough, on the toilet tank is now her cellphone. “I literally JUST got in the shower,” you lie, “Can it wait like five minutes?”

“FUCK. No, it can’t. I’m waiting on a phone call.”

“Is it important?” you ask.

“Yes, shit-for-brains, it's important!”

“Then just come in and get it.”

“Ugh!” she huffs, “FINE. Just cover yourself up.”

“Can do,” you lie, standing in full view of the door, naked as the day you were born.

“Alright, I'm coming in,” she says, opening the door and stepping inside.

Steam had already started to build up inside the bathroom, making it harder to see; even so, it took her no more than three steps to realize you weren’t trying to hide your modesty. She covers her eyes, her face turning a bright shade of red.

“GOD DAMN IT, ANON! WHAT THE HELL DO YOU-” She catches a glimpse of your hypnotic love rod from between her fingers and stops berating you mid sentence. She drops to her knees, her mouth watering. “Oh my god… It's so… so…”

“So?”

“So BIG!” She answers, sliding closer on her knees. “I-I want it…” she reaches her hand out, almost afraid to touch it; her eyes filled with longing.

You wish that any woman under your cock's irresistible influence would do anything you tell them and ask, “What do you want to do with your dweeby brother's monster cock?”

“I-I… I can’t… But, I… I want you… I want IT…” Her hands start to explore her body, hey mind engulfed with lust. She slides one hand down the front of her shorts, the other under her top, squeezing and kneading. Her breathing gets deeper and huskier, literally panting in heat as she's overwhelmed with desire.

“Jennie, stop touching yourself.” She groans in frustration, “B-b-but I NEED to do something about this… this NEED! I need it SO bad…”

“Then beg.”

Without a second’s hesitation she clasps her hands together, and pleads, “I-I b… I beg you…”

“Then get undressed and step into the shower.” She grins, standing up in a hurry and practically tearing off her tank top.

Your step-sister is attractive in that girl next door kind of way. She's thin and athletic from playing sports with a cute, round rear and a perky pair of breasts. While she's plenty attractive by her own merits, you think now's as good a time as any to live out a fantasy or two.
