[m4f]Curing my friend's depression with my hot gf

"I am 18+ and all participants and characters must be 18+"

I want to RP a prompt about a strong friendship, so strong I'm even willing to share you (my GF) to make my friend feels better. After breakup the friend I hold dear like a brother falls into depression, so much so he looses his job and I let him stay in our spare room. After a couple months since gets worse, and I believe what's preventing him from getting his usual confident and happy self is some female warmth that can help him get back on track. He's really fragile at the moment so I fear asking for a stranger might do more harm than good, that's where you come in. You have always had a caring and motherly side to you, helping my friend in these difficult times, so I figured you'd be the perfect one to help him get out of this. I've a few rules in mind to avoid things getting too out of hand, me being present and not penetration involved. What neither of us knew is how hung my friend really is...

I'm looking for someone fairly descriptive for this, if it looks like fun to you, hit me up with your descriptions and kinks
