Sen-chan and the Case of the Alpaca Milk

In searching for the perfect milk, Detective Sen-chan employs an experimental potion to shrink down and find the source. The source, however, is within Alpaca Suri's breast! Finding an opportunity, Sen-chan uses the potion in Suri's room while she sleeps and crawls on top of her nipple. But the detective doesn't realize how much of her touch arouses the alpaca. As Sen-chan slips into the nipple, it starts to harden and push her further than she anticipates. Swallowed by Suri's teat, Sen-chan must wait until the opportunity escape.
