No!!! Do not let him do that! Call the police!!!
If (presuming you are the 13 year old girl) you want him to touch you, then it is down to you to be responsible, but be warned that this is illegal in some places/states/countries for anyone under 16 to have sexual contact and perform sexual acts, and it is also illegal for somebody OVER 16 to touch someone UNDER 16 in this way. If you do not want this guy to touch you in this way, tell him this and then tell a trusted adult immediately.
