What am I supposed to do with a cucumber?

Mila Pie finally meets with Sherri Ost after a long wait. They get together and the chemistry gets unbearable from the very beginning. After getting home, she finds some lingerie and a... cucumber in his backpack?!? WTF is that? She's intrigued, a bit angry, and confused but he quickly shuts her up and asks her to put it on and she looks dynamite as expected! She forgets all about it (ofc) and starts kissing and blowing Sheeri right there making him hard and ready to put his cucumber to good use, as he should!
