I'm a 15 year old girl an I have stayed at my 20 year old guy friends house a couple of times now.
We hug, just like I do all my male an female friends. With him he really snuggles into me an likes me to play with his hair. When my arm aches from doing this is stop an pretend to be asleep. After a while he will start moving his arm an then hug my waist. He will put my hand where he wants his an then place his hand underneath like I want it to be there. Before we went to bed he was tickling my hands an feet an also touching my thigh. Then we started to play fight a little he was on top of me an I was laying on my front, my top kept coming up at the back, he kept pulling it down an then in the end put his hands up an started massaging me, he also slapped my butt a couple of times.
In bed he always wraps our legs together.
When he thinks I'm asleep he plays with my hair an kisses my forehead. Then later in the night he will but his hand up my tshirt an the second sleep over was touching my boobs. An he also had his hand on my *** the second time, an even undone my flies to put his hand in my jeans. Then lastly he takes my hand an starts touching his cock.
I never react, just make out I'm sleeping. Should I mention it to him?

Perhaps you should mention it to your parents, since a 15 year old has no business sleeping over night with a 20 year old.

Where are your parents and how do you manage to be sleeping over at an adults house?

Not only is what he's doing illegal and definitely makes him to be some kind of pig but I also have to ask why you're allowing this to happen? Tell your parents... stop going there. This could wind up being very, very bad for you if you continue it.

No you should NOT mention it to him. You should tell him that you are too young to be sleeping over at a 20 year old's house. Then you tell your parents about his feeling you up.

I too have to wonder at parents that would let a 15 yr old sleep over at a 20 yr old. Especially if he has his own apartment. And, if he lives with his parents, then why are they letting this happen?
