Actually, it has been known to happen. See below.
Among fraternal twins, in rare cases, the eggs are fertilised at different times with two or more acts of sexual intercourse, either within one menstrual cycle (superfecundation) or, even more rarely, later on in the pregnancy (superfetation). This can lead to the possibility of a woman carrying fraternal twins with different fathers (that is, half-siblings). This phenomenon is known as heteropaternal superfecundation. One 1992 study estimates that the frequency of heteropaternal superfecundation among dizygotic twins whose parents were involved in paternity suits was approximately 2.4%.
More about twins:
Fraternal twins (commonly known as "non-identical twins") usually occur when two fertilized eggs are implanted in the uterine wall at the same time. The two eggs form two zygotes, and these twins are therefore also known as dizygotic as well as "biovular" twins. When two eggs are independently fertilized by two different sperm cells, fraternal twins result.
Identical twins occur when a single egg is fertilized to form one zygote (monozygotic) which then divides into two separate embryos. The two embryos develop into fetuses sharing the same womb. When one egg is fertilized by one sperm cell, and then divides and separates, two identical cells will result. Depending on the stage at which the zygote divides, identical twins may share the same amnion (in which case they are known as monoamniotic) or not (diamniotic). Diamniotic identical twins may share the same placenta and chorion (known as monochorionic) or not (dichorionic). All monoamniotic twins are monochorionic. Also note that any monochorionic or monoamniotic twins are identical twins. This condition does not occur in fraternal twins. The placentas of fraternal twins may, however, fuse if their implantation sites are located close to each other. Fused placentas can be indistinguishable from monochorionic twins in prenatal examinations, and difficult to distinguish in the delivery room.

No, but an odd truth about twins is that if a woman has sex with more than one man while she is ovulating and ovulates more than one egg... she can get pregnant with faternal (not identical) twins that could even have different fathers. That's weird isn't it? Best wishes

NO WAY! Never be hesitant to ask any questions, it's when you don't ask that it becomes a problem.

nope- when a woman is pregnant she doesn't produce another egg to fertilize.
