I Don't Mind

"Really Billy....I don't mind if you wear my clothes....and I won't tell....but you'll have to do some things for me...."
"Like what...."
"Well for starters I want you to suck my nipples.....Johnny did that last week at the Drive-In and it felt wonderful!!!"
"Oh yeah I'd love to do that!!!!"
"And I can feel your.....thing is hard.....I don't want any of your stuff staining my clothes so if you feel like you have to squirt just tell me and I'll catch it all in my mouth like I do with Johnny!!!"
"You're the best Sis!"
"Get busy Billy....mom and dad will be home soon..."
