Clarify: If by lips you mean your mouth, then no. Oral sex does not cause pregnancy. If you mean your labia (vaginal lips), it is possible especially if the head of the penis causes the lips to spread open and he has pre-cum on this penis. A drop of pre- cum may have as many as 20 million sperm. While, this is much less likely that if he ejaculates it still slightly possible as sperm can swim.

No: Assuming that you mean lips on your mouth the answer is no. Penile insertion of the vagina is needed for pregnancy.
