Uke told the seme to stop and the seme did. Controlled himself and didn't push the uke too far.
While the uke does enter this bout of B/D under the pretense of being trained and then sold, the semes do what they know he'd like and aren't bullies. Plus something sort of heartwarming occurs at the very end (^_^)
While hit by a spot of nasty jealousy that accidentally injures Italy, Germany apologizes and the two sleep with each other. Germany takes his time with Italy and allows Italy to decide the pace and is gentle when penetrating Italy.
The seme is a much older man, a father, that picks up an abused young man. He is very much a replacement father figure but also a lover and is very gentle with the uke and also gives him a new home away from his abusive parents.
