Yes, it makes the most sense

Allie was my roommate; it made the most sense for me to be the one to help her to bed.

"Come on," I said, extending a hand to help her up, "Let's get you to bed. Maybe we shouldn't have let you end up with the dirty pint."

She didn't really respond, just slipping her arm around my shoulders and leaning all her weight on me so I wasn't so much supporting her as dragging her to our room.

I tapped my keycard against the sensor, pushed the door open with the weight of our bodies, and led her to her bed.

"Can't sleep like this," she said groggily.

"Like what?"

"Clothes. Need pyjamas. For sleep."

"I, uh... You'll have to deal with it for tonight. It'll be okay."

She nestled into a comfortable position on the bed and closed her eyes.

"Sam?" she half-whispered as I turned away.

"Yeah?"

"Thanks. You're a great guy. I like you."

"I quite like you too," I replied, turning out the light before stripping down to my boxers, still struggling to contain the erection I had been nursing on-and-off for a while, and climbing into my own bed.

"Let me know if you need anything," I whispered.

Allie responded with a murmur.

"Goodnight, Allie."

There was no reply. A quick glance over to her bed revealed that she was out cold. She looked cute sleeping.

I tried to sleep myself, but I wasn't yet that tired, and the girl in the window, combined with the sexy revelations that came out over the course of the evening – and, I'll admit, the pretty, drunk girl in the bed across from me – had left me in a somewhat excited state. Almost unconsciously, my hands reached down to lightly stroke my rock-hard cock through the soft material of my boxers. God, I needed release. There was no chance of Allie catching me this time – she was out cold – but it felt wrong to masturbate with someone else sleeping right there.
