Nice read as always; wasn't aware Sennet could go THAT fast! As for other questions...

A) What sort of girls does Sennet like?
B) What sort of girls does Erik like?
C) What sort of guys does Erik like?

Sennet is INCREDIBLY fast in short distances, yeah! but he needs lot of water and rest after a few times of that
Erik managed to catch him in some training times, but is very very hard

1) mostly cheerfull and playfull, not serious ones. about their body, he preffers tall girls, have no trouble if are a little chubby
2) he loves curvy girls, preferibly of his same height or a little less. not very crazy ones or super playfull, you know that Erik is not so crazy as sennet. Erik preffers girls that he could just sat with them and talk before have a sex encounter.
3) Ones that have no fear to make him enjoy lot of pleasure but not beiong around saying what they did XD about thir body, muscular and with short hair, with playfull hands but at same time not super horny and kinky. guys that respects him

Good answers!

i am slowly doing an adult drawing of Erik with girls AND boys at same time, actually. something like they helping him in a sexy way to forget the stress x3

It's a good way to relieve stress!

erik can be a fun guy but actually he is under TERRIBLE stress by have to be in alert all the time because the gangs chasing his tail, and also during the hockey games. so just being with friends or in that sexy moments can clear his mind. so the people that he met really tries his best to pleasure him, because is a good person

Aww

as you saw, Sennet and Almeta are always joking with him and also eating or having fun with him by the same reason x3

Good friends!

very good friends x3

Ahh, good stuff.

hope be interesting x3
