(This is a custom clip and I can make one for you too! Just send me a DM!!) The idea is you're a chemist, working on experimental viagra, you have some at home in the fridge because of step-sons you don't have to go into details with, but maybe you planned to do some off the books experiments with your husband. Either way my friends and I find it and sip it thinking it's kool-aid or something, but with developing/still growing boys has some unexpected side effects. It makes our cocks/balls larger, don't have to show that transformation or anything, just we turn up to you for help and you see our bulges - and it also makes us aggressive. So commentary from you would be how we're young, your step-sons friends, too big , worried about your job/pregnancy Would actually like just my friends to come in first and start, and I come in after they've used you a bit. I lingered because I ended up sipping more before we all realized what it was and my cock/balls/everything is bigger than them. Would like a bit more of a freak out about me joining as I'm your step-son and could impregnate you, stuff like that.
