He puts on a robe and answers the door

Adam pulled off his shirt (his last piece of clothing), and grabbed his bathrobe off of the floor. He managed to press his throbbing cock against his stomach and tie the robe tight just as he reached the door.

Devon and Clark jumped as he opened the door. They both wore a look of relief after they found him, but then quickly felt an jolt of embarrassment about why they had followed him.

"Hey guys. Come on in." They quickly slipped through the door.
