We have several vibrating dildos-a thick black one, a large jelly one and a smaller jelly one. We use them in a couple of ways. The first-she will put it into her vagina and move it in and out while she gives me a blowjob and we will fantasize that we are having a threesome. I will say things like we imagine the third person saying like how good it feels and how tight she is. Second-sometimes I will use a dildo on her while I masterbate and then cum on her boobs when she cums. Great toys.
