I've just got some new lingerie and a sex toy for my husband. He's been out of town for so long and I thought it would be fun to surprise him when he gets home. I'm already wearing my lingerie when my stepson knocks on the door. I let him in and figure I'd ask him his advice, you know, from the perspective of a male. I show him what I'm wearing, I think he approves. I also tell him about the fleshlight. I've never used one before, and I don't really know how it works. It doesn't come with instructions. He agrees to help me figure it out. I sit him on the bed and show him the toy. It feels so real and looks so good! I stick my fingers inside, but the only real way to test it out is with a dick. I convince my stepson to let me pull his pants down and try it out. It would really help me out if he let me borrow his hard dick for this, I mean how else am I supposed to learn? I give him a nice handjob to get him hard. I lube up the toy and squeeze his dick into it. Wow, he has a nice dick, I need to be careful, I'm so naughty! His father would be so upset! He starts to get really hard and it's pretty obvious he likes this toy! The only rule is, he can't cum inside it! It needs to get washed and look like new, and I just won't be able to live with myself if I know someone else came inside it before my husband does. This thing is a lot of fun, and it makes him really hard, he starts to moan and squirm and it looks like he's about to burst! Uh, oh! I don't know what else to do so I just pull the toy off his dick and open my mouth over it! He squirts a big warm load into my mouth and onto my face. That was a close call! Time to wash the toy and try it on my husband. Thanks for your help son!
