#17 - Mechanical + Denial (Pixiv Fanbox)

Ben Tennyson's been captured by a strange alien species intent on milking him for his semen. The cruel twist is that these aliens are only interested in precum, meaning he's kept on the edge of orgasm 24/7 without any chance of release he's become desperate for! All he can do is groan into his oversized gag alongside the dozens of other boy captives, hoping somebody somewhere will save him from this edging hell.
