Small penis humiliation, jerk off instruction, and cuck training by a lactating mommy. Some lactation but not heavily focused on it. I noticed you in the shower and you are really tiny down there. I ask you to show it to me and can't help but laugh at it and humiliate you. I say "no wonder you seem to like mommy's milky breasts, you mustn't have progressed passed that stage! and milk myself a bit through my shirt. I take pity on you and instruct you to jerk off your little penis, but you have to listen to everything mommy says meaning don't cum until I say so! I give some edging jerk off instruction while still humiliating you for your small penis. I remove my shirt and express a little milk, so you can see it drip down my breasts. After a little JOI, edging, and SPH, I start to talk about your future as a cuck since that is the only way you can please a woman. I give more JOI and eventually give you permission to cum. The last minute or two, I throw my shirt back on and tell you about how you are going to practice being a good cuck by helping mommy get ready to go out and find a big cock to fuck, and hear my moaning through the walls knowing you will never make a woman cum like that.
