His lesbian girlfriend gets a hand up her ass
The fact that they are both street whores and have known each other for as long as they can remember makes them even closer. This has not only made them develop an incredible affinity, it also allows them to understand each other much better, even without using words. At that point, one already knows what the other wants, which isn’t very difficult when your lesbian girlfriend gets a full hand inside her ass. It’s very easy to please such a slut, as you just have to shove giant things inside her pussy or behind and that’s it. The rest will be to let her have many orgasms and that’s it.
