Because I was in the mood:

How big is his cock

I base this on the average erect penis to be 13.12 cm (5.17 in) in length and 11.66 cm (4.59 in) in girth

Yami:

Size: He is long and thick no matter how you look at it, with relatively little foreskin. You can't wrap your fingers around him so that your fingertips would be able to touch. Which would translate into long foreplay sessions because he knows he needs to prepare his partner well. Length: ~20 cm (7,5-8 in) Girth: ~14 cm (5.5 in) Other: Has one massive, throbbing vein running down the length of the middle of the shaft Hair: He trims occasionally, but most of the time has at least an "aftershave". That being said, he does keep himself clean

Nozel:

Size: He is above average in length and girth, enough to be considered as "impressive", the tip of his cock is covered by foreskin before erection, but as he gets fully erect, the tip shows itself. Wrapping him with your fingers is possible, but it would require long fingers. Foreplay sessions are long, partly because he likes the build up Length: ~17 cm (6,5-7 in) Girth: ~12.5 cm (4,9 in) Other: Has a couple very prominent veins Hair: He keeps it trimmed at all times. There's a small patch of neatly cut hair at the base of his cock, but otherwise he's cleanly shaven and tidy.

Fuegoleon:

Size: He is well endowed, and he knows it. But not as much as to consider himself as "huge". He has little foreskin, and even while in flaccid state the foreskin doesn't cover the tip, but stays at the base of the tip. Girth is decent; at the thickest point your fingers are not able to wrap around him. Foreplay sessions are long, but mostly because he enjoys teasing and making his partner feel good Length: ~18 cm (7-7.5 in) Girth: ~13 cm (5.1 in) Other: He has a couple of larger veins here and there, but not so much larger that they'd stand out from the rest Hair: Keeps himself cleanly shaved at all times. Even to go as far as to apply some gently deodorant on his inner thighs.

William:

Size: He has good reach, and grows the most in length between flaccid and erect states out of his peers. He also does appear to have a lot of foreskin in flaccid state, but it's all stretched out by the time he's erect. Girth is alright, but one is able to wrap their fingers around his shaft. Foreplay is drawn-out because he's gentle and doesn't want to be too assertive in the bedroom Length: ~16 cm (6-6.5 in) Girth: ~12 cm (4.7 in) Other: Very veiny, with good sized, throbbing veins Hair: He shaves around once a week, but does keep a patch of hair around his cock. He's mostly concerned with shaving under his balls, because he finds the hair there to be itching and uncomfortable

Jack:

Size: He's long and thin, with decent foreskin. But honestly, one barely notices because he's very energetic in the bedroom. Wrapping fingers around his girth is doable, if you manage to make him still. Foreplay with him is sloppy and hasty, like he couldn't contain his excitement Length: ~17 cm (6,5-7 in) Girth: ~11,5 cm (4,5 in) Other: He has a couple of scars around his lower abdomen, of which he doesn't want to talk about (it's shaving incidents) Hair: Shaving isn't his forte ironically. So, there will be patches of hair here and there, but he does keep himself cleaned up

Julius:

Size: He is very sturdy, alright reach. The foreskin does require pulling back even while erect, but he is also meticulous about keeping himself as fresh and clean as possible at all times. Wrapping fingers around his cock is very difficult, even with long fingers. And the make-out sessions are usually long, because he knows that he needs to get his partner loosen up Length: ~ 14,5 cm (5.7-6 in) Girth: ~13 cm (5.13 in) Other: Very evened out cock, neat and "pretty". But sturdy. Very sturdy Hair: He has a patch of hair over his pubic bone, but otherwise it's clean shaved. Well trimmed, cleaned and tidy

Nacht:

Size: He's on the shorter and girthier side as well. But has little foreskin, and not prominent veins either. However, due to the bulkiness of his cock, he also tend to take his time with preparing his partner. Length: ~14 cm (5.5 in) Girth: ~13,5 cm (5.3 in) Other: No prominent veins, very smooth cock Hair: Keeps himself meticulously trimmed and hairless

Rill:

Size: He has a very cute penis. It's on the average side when it comes to length and girth, but he's also very sweet and energetic in bed. He has a decent amount of foreskin, but it stretches out when he's erect. And foreplay is long and sweet Length: ~13 cm (5.12-5.3 in) Girth: ~11.5 cm (4.55 in) Other: A couple prominent veins Hair: Has a patch of hair over his pubic bone that he likes to make of different shapes regularly

Morgen:

Size: He's on the longer and thinner side, with a couple of prominent veins. He also has a good amount of foreskin, which needs to be pulled back, even when he's erect. Foreplay with him is fast paced and sloppy, because he's much more eager than he might appear in public Length: ~17 cm (6.5-7 in) Girth: ~12 cm (4.7 in) Other: Has a couple of very prominent throbbing veins (don't run your finger over them, away such thoughts~) Hair: He keeps a very neatly trimmed patch at the base of his cock; it's like even that patch doesn't grow ever!

Marx:

Size: He is far bigger than one might expect. He is quite short in height, but is well endowed in other aspects. He has minimal foreskin, and an impressive girth. Foreplay tends to be "heavy" and intense, and he is one to take charge Length: ~17.5 cm (7-7.2 in) Girth: ~14 cm (5.5 in) Other: A lot of veins, even the smaller ones you can see look big Hair: Not a hair in sight below the equator
