Wife's oral skills put to the test by a professional

After a long day at work, I couldn't wait to get home and enjoy some quality time with my girlfriend. I knew she was eager to please me, but I had a sneaky suspicion that her oral skills could use some improvement. As soon as we got to the house, I wasted no time in putting her to the test. I introduced her to a friend of mine, a true connoisseur of pleasure, who was more than willing to help me out. He took her to the guest room, where he proceeded to give her a run for her money. His skills were unmatched, and he made her work for every last drop of his creamy delight. Watching her lick out every bit of his seed from his throbbing member was a sight to behold. I could tell she was thoroughly enjoying herself, and I hoped this little test would help her hone her skills.
