Briefly

You and Kathy stop just short of running into the twins, they themselves coming to a stop when they get a load of Kay's skimpy outfit, and the naked guy jerking himself off right behind her.

"Wow!" One of the two exclaims. I didn't know which was Rhonda, and which was Ramona "What's with the outfit, Kitty Kat?"

"Some wise-ass stole my regular clothes from my gym locker, this was all I had," Kathy explained.

"Well you look great Kay!" the other twin declared. "Super sexy."

"Hot!" added the first twin. The two of them very casually reached out and gave a friendly tweak to each of Kathy's exposed nipples, like it was the most normal thing in the world.

Still pinching your friend's nipple, the second twin asked, "aren't you going to introduce us to your naked, masturbating friend?"

"Of course, how rude of me. John, this is Rhonda," she said, gesturing to the first twin. "And this is Ramona. Rhonda, Ramona, this is John Doe. You probably heard them talking about him on the morning announcements."

"Very nice to meet you, John," said Rhonda, sidling up to her sister.

"A pleasure," added Ramona, resting her chin on Rhonda's shoulder and gently caressing her twin's abdomen. Rhonda reciprocated this affectionate touch, stroking her sister's inner thigh, just above the knee through the skintight denim. They seemed very comfortable with each other.

"Well, anyway, I was just taking John to the nurse's office--"

Ramona whispered something to Rhonda, her lips pressed against her sister's earlobe, causing her to smile. "We're headed that direction ourselves, to programming class. Mind if we join you?"

The four of us walked along the connecting hall, the sisters hands around each other's waists, Kathy recounting the incident in the showers, and I, synchronizing my cock stroking to the rhythm of the conversation. Just as the twins broke off to enter their computer class, it occurred to me I needed to pee.

"Here we are," Kat announced, standing in front of the nurse's office.

"Are you coming in?" I asked, "Or are you headed straight to class?"
