I was surprised when my childhood friend sisters, who I thought were cute, started talking to me, but it turns out they've recently gotten boyfriends, and they're virgins. "We've always left it up to the guys, so we don't really know how to treat a virgin... so you can be my practice partner! My parents won't be home next weekend, so come over to my place!" They called me out, half-forced, and asked me, "How's this kiss? Does a blowjob feel good? Do you want to cum inside me?" I spent a happy day at the mercy of the two teasing girls, having sex all day while my parents were away.
